Woodturners Wonders lamp

Good lighting is one of the most under-appreciated assets for fine woodworking, especially handwork at the bench. It is a shame to see an elaborately equipped shop with nothing more than fluorescent ceiling lights illuminating the workbench.

Basically, the properties of lighting are intensity, distance from source to the object, angle of incidence, and quality, which includes the color cast (color temperature). Without delving into technical detail, for detailed tasks such as hand cutting joinery, you want a strong light that is adjustable for distance and angle, and has a pleasing whiteness.

The Super Nova lamp from Woodturners Wonders delivers big time on all counts. It was developed by woodturner and inventive guy Ken Rizza for use with a lathe but is just as useful for general woodworking. The three LEDs in the lamp head together use 9 watts of power to generate 870 lumens.

This is a heavy-duty lamp. The 30″ flexible stainless steel neck, covered with a black flexible, non-reflective shroud, holds its adjustment in any position. This is the key to the effectiveness of a lamp like this – the light can be adjusted to the exact location and direction desired and it stays put. The heavy rectangular base houses a switchable magnet that holds with 286 pounds of force! The base is large enough to easily accommodate a clamp to secure it to a wooden surface.

Below is not trick photography. The base is holding unyieldingly to the even the 2mm sheet steel of the bandsaw cover, while the neck does not sag a bit when fully extended. Wow!

The LEDs are rated for 50,000 hours life (8 hours/day every day for more than 17 years). The lamp is equipped with a generous 9-foot cord. Unfortunately it ends with the obligatory transformer but at least this one is small and light. A minor complaint is that I wish the switch button was placed on the back of the lamp head instead of on the side of it because I tend to switch the lamp off when grabbing the head to adjust it.

This bad boy lamp is not cheap at a regular price of $159 (look for sales) but a good light is one of the most important tools in the shop. It is by far the best lamp for detailed bench work that I have ever used or seen. Several cheaper “good” task lamps have frustrated me over the years. I cannot at this time attest to its durability but it certainly seems sturdy and does carry a two-year warranty. Smaller models are available.

I suggest trying a top quality task light in your shop. You may be surprised what you have been missing as you experience the improved visual feedback for detailed handwork, and using a raking light for surfacing and finishing.

Sensgard Zem hearing protectors

These Sensgard Zem hearing protectors are the best I have ever used. Before elaborating, I will explain the problems I have had with some other protectors.

I do not like stuffing things into my ear canals. This includes foam plugs that are first compressed with the fingers, which are often dirty, then jammed in where they are uncomfortable and then tend to work their way loose. Various silicon, latex, or high tech torpedoes that are also held in the ear canal much as a cork is held in a wine bottle are also unwelcome in my ears.

Bulky, cumbersome earmuffs are at the other end of the range of options. I have top-quality Peltor muffs but even with their soft padding, they squeeze the temples of my eyeglasses uncomfortably against my skull. It isn’t long before I decide the noise is more tolerable than the headache.

Finally, all problems are solved with Zem hearing protectors by Sensgard. The replaceable foam cuffs of these extremely lightweight protectors comfortably skirt the entrance to the ear canal. The acoustic chambers (the arms) vault my eyeglass temples – no more skull aches. They go on and off in a snap, and when not in use, hang around the neck or fold compactly for storage.

All these advantages would be enough but here is the best part: the noise reduction is phenomenal. I powered up my DW735 thickness planer, measured 100 dB(A) at 2 feet under no load, and then put on the Sensgards. I was flabbergasted at the dramatic but even, pleasant noise diminishment. The nominal NRR (Noise Reduction Rating) is 31 but they are far more superior to my Peltor model, listed at 28, than the numbers might suggest.

I actually had to accustom myself to remaining alert to the ferocity of woodshop machinery while enjoying the auditory peace. Yet, I could adequately hear important shop sounds such as speech.

More information about the Zem technology is available on the Sensgard website. I have the NRR31 model in easy-to-find lime green. Put them on according to the simple package instructions; that makes a big difference. I found the lowest price on Amazon. Extra foam cuffs are good to have.
