router table miter slot

Devoted readers (thank you!) know that I like to keep my router table simple but very capable

The router table is truly a key tool in the small shop but there is a wide range of complexity and cost involved. I admit to being intermittently tempted by router lifts, tracks and slots in the table and fence, bit changes and height adjustments from above the table, and micro adjustability of almost everything.

Yet, my simple set up continues to do everything required. It consists of an MDF top and fence on a 2×4 base, dust collection, and the Bosch 1617EVS held in a dedicated base attached underneath the table. Moreover, the flatness accuracy of the top equals the best tables reviewed in Fine Woodworking magazine #237, and it substantially exceeds most of them. Some of those rigs cost more than ten Bens. 

But what about routing a rabbet or profile on the end of a narrow stick, or, more challenging, a dado in the middle of, say, a 4″-wide rail? I again admit to being tempted by an impressive cast iron tabletop with a miter gauge slot. 

router end grain on router table

For routing on the end of the stick, the workpiece alone gives too little registration against the fence. Therefore, I have usually used a squared piece of plywood or MDF, about 10″ x 12″, to register the workpiece against the fence and prevent tearout at the trailing edge. (See photo just above.)

However, sometimes it is handy to use a miter gauge, especially for a short dado. This also allows me to register the left end of the workpiece against the miter gauge stop for a repeatable task.

Well, there just is not enough depth in a 3/4″ MDF top for a metal-lined track for a miter gauge. (Unlike for a T-track, which is more shallow.) Thicker MDF is an another option but that would mean a new table top that would require a recess to mount the router base. A bare slot in the 3/4″ MDF is also problematic in that it would wear quickly. I could line the slot with UHMW tape but it would be hard to get the width just right to avoid having to adjust my miter gauge bar every time I brought it over from the table saw. 

So, as usual, I turn to the late Pat Warner’s writings for a solution. On page 99 of his The Router Book, there is a simple way of making a temporary “slot” in your MDF router table top. My version uses nominal 1/2″ MDF with adhesive UHMW tape on inside edges. (See the photo at the top.) The outer board is screwed down in the near right corner to give more clearance for the miter gauge head, and elsewhere the boards are clamped.

This allows me to use my table saw miter gauge – the wonderful Incra 1000HD and its adjustable end stop. Note that I do not need to adjust the width of the bar. Instead, I retain the setting that works for the table saw, and then for the router table, simply set the two MDF boards snugly against the bar for a wobble-free fit. A backer board prevents tearout at the trailing end of the workpiece. The router table fence is not functional for the cut itself but is close by for dust collection if possible.

It looks like I just saved several hundred dollars yet again. 

Mmmm, that walnut looks nice.

DeWalt cordless sander

The DeWalt DCW210 is a cordless 5″ random orbit sander that is powered by the company’s 20-volt lithium-ion battery system.

Smitten with DeWalt’s 20V Max series of tools, it is a bit like dealing with Apple stuff. I know I’m being played but the products are just darned good. 

Handling is excellent. Weight, vibration level, and control are comfortable. With a top grip, the only option, the sander tends to meet the work squarely with no tendency to tip or gouge. At least with a smallish 2.0 amp-hour battery, balance is excellent. The rubberized area enhances the feel, and the on-off switch is easily accessible from the grip position. 

This is a finishing sander, not a stock removal hog. In that context, it has plenty of power. It is similar to my Bosch ROS20VS, if not more aggressive. The DCW210 has a standard 8-hole base with hook-and-loop disc attachment, and runs with a 3/32″ diameter orbit. The brushless motor is very efficient, so I read. It has a variable speed dial, also accessible from the grip position, but I rarely use that option on a sander. 

You’re going to love this as I do: the motor brake stops the motion immediately when you hit the power switch. Hallelujah!

Dust collection with the onboard bag is surprisingly good but of course, no match for sanding with a vacuum hose. (I vacuumed up the tool nice for the photo.) The bag’s good-sized plastic collar and locking system makes it easy to use one hand to detach and attach with a nice positive click. A spring that lines the bag can be compressed and popped to “shake out” stubborn dust. I find it is more useful for allowing a vacuum hose to thoroughly clean out the bag without it being sucked into the hose. 

The outlet diameter will not fit standard shop vac hoses but this does not matter to me because using a cordless sander with a hose would pretty much negate the advantages of having no power cord. So I will use this sander without tails of any sort.

I cannot offer data on how long the battery charge will last. After a while of sanding, I check the charge-level indicator on the battery and replace it if it is low. With just two extra lightweight 2.0 Ah batteries on hand and using the DCB113 charger, I could keep working indefinitely. You can also buy higher capacity batteries but I guess at some point the weight would get uncomfortable. Anyway, this is a finish sander suited for relatively light work. Note that DeWalt charger models vary considerably in their charge time.

I will still use my bigger Bosch 3725DVS (3/16″ diameter orbit) with its cord and a vac hose for heavier work but the DeWalt DCW210 is now my go-to tool for finish sanding. 

This review is unsolicited and uncompensated. I just want to help you choose good tools.

workbench height

In a 2011 post, I argued for an empirical approach to determining your best workbench height instead of relying on any formula. The many variables in body characteristics, woodworking styles, and tools necessitate practical testing.

Consider the tasks you do at the bench, such as planing, sawing, and chiseling, and the portion of time and effort you are likely to devote to each category. Then find a workbench, Workmate, or a sturdy table to try the work at different heights created by clamping layers of boards or plywood to the table. Find what feels best all-around. 

Maybe your ideal bench height will change over time as mine has. Recently, after assessing how I was working, and then testing just as I recommend to others, I raised my bench almost two inches to 37″. I feel more comfortable overall, particularly being able to stay closer to a neutral head posture. I can reduce the bend in my neck, which reduces stress on the lower cervical vertebral joints. 

On the other hand, I can feel that the higher bench height transfers more of the work of certain tasks such as heavy planing to my upper back and arms. Fortunately, I’ve maintained good upper body strength, especially in the upper back and shoulders, so I don’t seem to miss the reduced drive from the ground. In fact, firming my upper back as I work actually further removes stress from my neck.

I used long #14 screws to attach a glued stack of Baltic Birch plywood to the base of the bench, replacing the previous riser blocks. 3M Safety-Walk slip resistant tape applied to the bottom along with filler blocks between the bench and the back wall do a great job of keeping the bench stable in all directions.

Assess your stress” and work habits to make your shop time more efficient and pleasant.

making a dovetail marker

The process I used to construct these markers ensured their accuracy.

I used bubinga but many dense, fine-grained hardwoods such as hard maple would do fine. Start with a 1 3/8″-thick, flat board without internal stresses, at least 12″ long and 5″ wide for safety, with a straight, squared long grain edge.

Using appropriate safety precautions, make a 1″ x 1″ rabbet on the long grain edge. I used many shallow passes with a 1″ diameter straight bit on the router table, finishing with a light pass over the entirety of the inside surface.

On the table saw, rip away a 1 1/2″ strip containing the rabbet. 

For safety and accuracy, short pieces – the markers themselves – will be cut on the table saw from this long work piece.

Two principles guide the process. We want to work with the rabbet always facing the blade to eliminate even the minor tear out that can occur at the trailing edge of a cross cut. This keeps the inside edges of the marker crisp. This also keeps the work piece stable against the fence.  

We also do not want to reset the miter gauge in case there is even the slightest inconsistency from the right side to the left side settings.

So, prepare by making a wedge. Use the miter gauge to cross cut a squared edge on a piece of scrap or MDF. Then set the miter gauge at the desired dovetail angle and cut off a narrow wedge. Glue sandpaper to the angled edge, and to the straight edge if you don’t have sandpaper on your miter gauge fence. 

Use the wedge against the miter gauge fence, set at 90°, to cross cut the end of the work piece held against the wedge. This creates one side of the marker (as in the photo at top). Then, flip the wedge end for end, and cross cut to produce the finished marker about 1 1/4″ wide (as below).

making a dovetail marker

Check the marker with a square and bevel gauge. Both sides should be the same. Chamfer the non-working edges on the outside. Label it with the dovetail slope – I carved the numbers. The oil (non-film) finish has worked well over the years.

For reference: 5:1 = 11.3° 6:1 = 9.5° 7:1 = 8.1° 8:1 = 7.1°

dovetail marker

Make dovetail layout easier and speedier with these shop-made markers. I have been using them in my shop for many years. 

Unlike most commercially produced markers, they allow you to pencil the entire length of the line on the end grain and face grain with one positioning. This produces an accurate alignment of those two lines, which in turn helps you saw accurately. They work for tails-first woodworkers as well as pins-first iconoclasts.

The outside dimensions are 1 1/2″ tall, 1 3/8″ deep, and about 1 1/4″ wide. There is 1″ of length on the inside of each arm of the marker, which will accommodate almost all dovetailing for most woodworkers. 

They are easy to make in a variety of dedicated dovetail slopes. No more setting a sliding bevel.

dovetail markers

You can also use them to square the pin layout on the end grain (that you transferred from the tails) down the side of the pin board with a pencil to help guide your saw. 

Note that there is no “relief” at the inside corner of this marker. All the working edges are crisp. A relief at the inside corner, though present in many, if not most, commercial markers, is unnecessary and misguided. Come on, who has “saw whiskers” on the pieces they are about to dovetail? The relief causes a break in the pencil line at the corner of the work piece, thereby disturbing an important visual link for guiding the saw.

The construction method makes these markers as accurate as anything you can buy. And, of course, the cost to make them is negligible. 

I detailed their construction in an article in Popular Woodworking magazine, November 2009, issue #179, but now I will present show the simple process here on the Heartwood blog in the next post.

shooting board

Here are the details of the shooting board I use. It is designed for use with the Veritas shooting plane, as well as to fit my workbench, the work I typically do, and my personal physical characteristics (I’m right handed).

It is constructed primarily from 18mm 13-ply birch plywood. The base and thus the overall dimensions are 22 3/4″ x 14 1/2″. The platform upon which the workpiece rests is 11 1/4″ wide, and is glued and screwed to the base.

The right side of the platform was planed accurately straight before installation. The tiny rabbet, which is the basis for how a shooting board works, is created with the first few passes of the plane that “break it in.”

Porcaro shooting board

The cleat at the front, glued and screwed, hooks onto the front of the workbench. The cleat on the right side fits into the tail vise. Together, they give the shooting board rock-solid stability in all directions while in use.

The channel for the plane is about 2 1/8″ wide, and lined on the bottom with 3/64″ PSA UHMW plastic. The 9mm 7-ply birch strip, 1 7/32″ wide, on the right side of the channel is adjusted to create a snug fit for the Veritas shooting plane, and firmly secured with pan-head screws placed at 3″ intervals. It is not glued, so it can be adjusted if needed. The inside wall of the strip is waxed.

Porcaro shooting board

The fence block is 2 1/4″ wide, made from two glued layers of the 18mm plywood. It is glued and screwed square to the sole of the plane nestled in the channel. The 3/4″-thick (or 7/8″) poplar replaceable subfence is attached with two 3″ x 1/4″ lag screws that enter from the back of the fence block, accompanied by heavy washers. The pass-through holes in the fence block for the lag screws are actually small slots that allow for some lateral adjustment of the subfence. You may want to use a third lag screw to ensure the subfence is snug against the fence block. 

shooting board fence

There are three ways to tune the 90° angle of the subfence. You can use whatever suits you; that is a big advantage of this design. Remember, we are using the in-place sole of the plane as a reference, not the channel edge itself. 

First, when you create the subfence itself, you can easily plane it as needed – it’s friendly poplar. Then, when you attach the fence you have the chance to put very thin shim(s) between it and the fence block. Now, if you placed the fence block dead on and use a perfectly thicknessed subfence, you should not need to do this, but it is good to have the option! Finally, when in use, you can put a piece of tape or a shaving between the workpiece and the subfence to fine tune the working angle.

For angles other than 90°, you can make and attach a different subfence.

The front of the subfence is 7 3/8″ from the back edge of the shooting board. This gives more than enough length to fully support the 5 1/2″ toe of the Veritas shooting plane. I prefer the plane to have full registration against the channel edge all the way through the cut. There are many shooting board designs with the fence at the end, which causes the plane to lose full registration before the cut is completed.

Also, the 7 3/8″ works out to make the front of the fence not too far away from me, so I don’t have to lean forward too much, while still allowing the base of the shooting board to reach across the tool trough to get full support from the rear wall of the trough. This also results in enough platform depth to accommodate the vast majority of workpiece widths that I use.

The 11 1/4″ fence is long enough to firmly register almost all the work I do. You may want to make your shooting board wider. For any board longer than 20″ or so, I stack a couple of pieces of plywood under the left side of it to prevent it from tipping up at the working end. 

The screw eye allows you to store the shooting board on the shop wall, away from abuse.

Remember:

  • sharp!
  • dynamic stability in use
  • low-tech micro-adjustment
  • and . . . the grippy glove on the left hand

I put a lot of forethought into this design, gathering ideas from many other designs. It has worked out very well for me. I hope it helps you with your work.

Addendum:

A plane such as the Lie-Nielsen #9 or a bench plane on its side can be gripped directly above and just behind the cutting edge. For these planes, a snug enclosed channel in the shooting board, such as shown here, is still very helpful but not essential. For the Veritas (or Lie-Nielsen) shooting plane where the grip is far behind the cutting edge, a snug channel is, in my opinion, a practical necessity. The grip location in these planes makes it too easy to get off track in the shooting stroke. Both systems work but I have come to prefer what I have detailed here for you.

DeWalt medium trigger clamps

No respectable woodworker can venture to the local Home Depot for that next-on-the-list home fixit thingy and resist a stroll through the tool corral because, you know, there might be something there that you absolutely need without having realized it. So, in this lucid state, I acquired a few of these little DeWalt trigger clamps

DeWalt calls them “medium” but I rate them: small enough but strong enough. They are an excellent alternative to spring clamps, which I have never really liked. 

The 2 5/16″ (actual) throat depth is at least that of most spring clamps except for some awkwardly large steel and ratcheting models. The 6″ clamping length of the model I use is longer than nearly all spring clamps. There is remarkably little bowing of the I-beam bar even with the maximum force applied, which is nominally 100 pounds. 

The fixed jaw can be reversed for spreading. The jaw pads have horizontal and vertical V-grooves for use on corners and small round pieces. 

A trigger clamp is not quite as easy to use one-handed as a spring clamp. However, they are still convenient to apply with one hand if you preset the jaw opening, then carefully set the first jaw flat on the workpiece, and finally squeeze the handle to plant and tighten the second jaw. 

DeWalt’s trigger clamp series also includes “small,” which is too tiny for much use in my shop, and “large,” which I skip in favor of the “extra large,” which generates 600 pounds of force. I wrote about those in another post.

Veritas shooting plane

Shooting is a gateway skill to precise hand tool woodworking. So get started by shooting with the planes you have. 

The basic requirements are:

  • Mass. You want substantial momentum to firmly and steadily carry the blade through the cut after you get it started, especially for end grain shooting. 
  • The side of the plane should be square to the sole. If you only have a not-so-great plane, use tape to shim the side. I did this with my old Record jack plane when it was the only one I had. [Please see in the Comments section reader Michael’s germane point and my lengthy reply for more details on the squareness issue.]
  • It helps a lot to have a comfortable, secure grip to consistently apply pressure where it is needed. Dedicated shooting planes have this feature. 
  • The blade must be sharp. Sharp! A dull blade is not only harder to push through the cut, but accuracy will suffer as the plane and the blade itself deviate from a true path. 

For end grain shooting:

Best: a dedicated shooting plane. 

Veritas shooting plane

I use the Veritas shooting plane, and love it. Comfortable and accurate to use, it meets all the requirements above. The adjustable-angle handle properly and comfortably directs pressure, and the 20° skew really eases the blade through the cut. The bevel-up design is easy to set up and adjust, and provides excellent support to the blade close to its edge.

Is it worth spending about $350 dollars on a plane just for shooting? In view of all the other expenses involved in woodworking, yes, it is. (See the first sentence of this post.)

Lie-Nielsen also makes a great shooting plane, which I have had a chance to use briefly. This massive tool uses a bevel-down design and a skewed, Bedrock-style adjustable frog. Personally, I like the Veritas design and features, but both merit consideration. 

I use a straight edge blade for end grain shooting – no camber

Good: a bevel-up bench plane. 

Veritas jack plane

The Veritas BU jack plane is perhaps the most versatile plane of all, and a good shooter. The BU design gives good blade support, and makes it easy to swap dedicated blades for its varied uses. You can get a decent grip on this plane for shooting.

Adequate: a bevel-down bench plane. 

I used a BD jack and jointer for shooting for years. I do not consider these ideal but they can get the job done. Don’t let anyone tell you that you “can’t” cut end grain with a bevel-down plane. Use a sharp blade, and set the chipbreaker close to the edge to reduce deflection.

bevel-down jointer and jack planes

Gripping a bevel-down bench plane for shooting may be a bit awkward for some. With the jack, I squish the base of my thumb behind the side hump and plant four fingers on the lever cap. A grippy glove can help. (So then you’ll have one on both hands.) 

For long grain shooting:

Compared to using a plane with the blade on the bottom (the “regular” way) this is just a matter of different manual mechanics. The plane is not running in a track as in end grain shooting. 

So, a BU or BD bench plane is fine, as long as it has decent mass and stability, the side is square to the sole, and you can get a decent grip. And . . . the blade is sharp.

I like my Lie-Nielsen #9 “iron miter plane,” which I’ve dedicated to long grain shooting, because its beefy, boxy design makes it stable through the stroke, and it handles exceptionally well with the “hot dog” grip. This is a bevel-up design with a 20° bed. (Hmm . . . ) Unfortunately, I don’t see it on their website any more. Veritas sells a somewhat similar plane. 

Lie-Nielsen #9

I keep the #9 set up with a straight edge blade, mostly because it is easier to maintain and works well for the thin stock that I’m usually using when long grain shooting. A mild camber, such as for a jointer plane, is also a good option, especially if you will be long grain shooting thicker stock, or if you are also using the same plane and blade for general tasks.

woodshop shoes

Have you given much consideration to your footwear in the shop?

The power input and the control of your tools originate from your stance. If it’s not well placed and reliable, your performance will suffer. You will also fatigue sooner.

Dependable footing is also essential to safety, especially with machine work. There, you cannot afford to compromise.

Our shop floors are usually littered with sawdust and shavings even with a good dust collection system gathering most of the waste from machine work. No matter what type of floor is in your shop, these make it potentially slippery. 

That said, sure, I’ve been known to get a few things done in my jammies and slippers in my home shop. But for serious work, I like low-cut hikers or at least trail-running shoes. Lately, my favorites are these sturdy Red Head Blue Ridge Low Hiking shoes from Bass Pro Shops. They have good support, wonderful grip, and a beefy toe cover. And the camo accents look kinda cool, don’t ya think?

[I have no affiliation with Bass Pro.]

Tormek with felt wheel

For a long time, I have not liked the leather honing wheel on the Tormek. I never used it for general sharpening because I prefer stones, but even for knives, gouges, and an occasional touch up of other edges, I find it fragments easily and does not hold the honing compound as well as I would like.

I finally got around to setting up the wheel with felt. It was easy to remove the leather and scrape clean the plastic base of the wheel. 

I got the felt from McMaster. I first tried PSA-backed felt just for the convenience of applying it to the wheel. The hardest available in this style was “Firm” F1. A 3/16″-thick strip proved to be still too soft.

The harderHard” felt is available only in sheets without the PSA backing. I cut the 1/8″-thick, 12″ x 12″ sheets into strips and applied them with 3M General Purpose 45 spray adhesive using simple butt joints to make a continuous layer around the wheel. The S2-20 (durometer 50A) works best. The S2-32 (durometer 80A) is nominally about half as compressible as the S2-20 but the difference does not seem to matter for this purpose. I prefer the texture of the S2-20 as it seems to grab the honing compound better.

Because I use the wheel for fine finishing, I charged it with 0.5 micron diamond. Mineral oil-based paste and water-based spray will both work but I think the paste is better. They cut fast but can get expensive over time. An economical alternative is a stick of Formax “green micro fine honing compound,” which I surmise is also about 0.5 micron, available from Woodcraft. Of course, it cannot cut as fast as diamond but with patience it can still produce an excellent edge. 

My preference is mineral oil-based synthetic diamond paste from Beta Diamond Products. It cuts fast and consistently, and a little bit goes a long way. I find the jar easier to deal with than the syringe. 

Bottom line: the felt replacement works very nicely; I like it a lot better than the leather wheel. It is especially helpful for knives, gouges, and is even handy for quick touch ups of plane blades and chisels. I keep these touch ups very light because I don’t want to round the edge too much, which would interfere the next time I work the edge on stones.
