Re: Coolest or most useful tool that you have?

in some ways, a cool tool is my Rockwell Uniplane - it can surface just about any wood in any orientation, and down to very small pieces. Woodturners such as Max Krimmel (he's also a guitar builder) use them to surface and build up stock by gluing small pieces together. I have also seen a video wher...

Re: Handy pointed tool

I stopped using knitting needles when I poked one in the right ear, and then the point emerged from the left ear. My dignity was compromised.

Re: Acrylic Templates

Who needs high speed tools? A leisurely cut with a fine-toothed bandsaw and then a trimming with a sanding drum on a drill press cut the outline without a fuss. It would have been no more difficult if it had been 1/4" acrylic or polycarbonate. The template in the picture was made with ordinary windo...

Re: Acrylic Templates

Here's one that I made. I had the plan copied (be sure to take a ruler along to measure the copy!). Then I applied 3M SprayMount (or 77?) to1/8" acrylic and laid the copy on it. After the adhesive was set, I cut away and removed everything but the outline & bracing pattern. I use spirits of naphtha ...

Re: 1HP motor: any benefit to wiring 220 vs 110

I think Brian has explained it very well. That said, after moving a 1.5HP tool from one place to another, for convenience I rewired the motor from 120V to 240V (both circuits were short runs of 12ga wire. The tool seemed to start with a stronger 'zing', but it really made no difference in the perfor...

Hmm, weren't you the guy who was wondering if it would be possible to build without a shop? These machines do take up space. Where would you use it and store it?

Re: Broken router collet. Why?

It's fortunate that you weren't injured. This is the first time that I've heard of a collet breaking, but come to think of it, I've never tightened a collet without a bit in it. On router bits that I use frequently, I put a rubber O-ring on the shank at the proper insertion depth. It also acts as a ...

Re: Dust Collectors

The static is a nuisance but is not dangerous except in factory-size installations. Some plastics are more susceptible to static charge accumulation. Aside from that, dryer vent hose may not be the best choice for a duct because it's corrugated and often very thin-walled. Try using rigid Sch 30 sewe...

Re: Using a clothes steam iron for bending sides?

I don't have any pics or the unit anymore, but I re-engineered toaster oven (~1500W) as a heat source under a Fox style bender. The thermostat was of good quality, but after relocating the sensor under the bender it was necessary recalibrate the knob.

Re: Is this style dust collector a complete waste of space?

Generally, manufacturers' CFM specifications are notoriously misleading. For any given D/C unit, the true CFM will be determined by the characteristics of the duct system from a tool to the unit, including the diameters, lengths, number and tightness of turns, That said, often the downfall of most o...

Re: Ikea in guitarbuilding? Thinking of making a Breim/Vuku spraybooth

Matthew - the parrot (aka Versa-vise) vise should serve you well. The Stew-Mac 'luthier ' vise is an old design that was favored by gunsmiths, and I suspect it became an 'essential' tool after it appeared in Cumpiano & Natelson's book. You don't need it. As Clay suggested, a portable work bench/tabl...

Re: Ikea in guitarbuilding? Thinking of making a Breim/Vuku spraybooth

Well, they don't look expensive to try out. How would you deal with fumes and overspray? I would be hesitant to use a fan due to possibility of explosion even if it were a brushless DC muffin fan.

Re: Cheap chinese cyclones: any good?

Yes, they are not inherently stable. The best setup I've seen has it and the vacuum on a trolly tied together. Otherwise you should probably find something vertical to tie it to. It has a tendency to want to topple over. If it isn't standing upright, it isn't working. Good point there - that's why ...

Simon, I made my own mini-cyclone separator after looking through Bill Pentz' site, and I installed it as a fixed wall unit. I've made another for a location where several tools are grouped. The construction method is the same as I developed for a large 16" dia separator that I made many years ago, ...

Re: Great hobby knife - highly recommended

Bard-Parker makes a #11 blade with a rib back that strengthens it. It's certainly bad technique to pry or scrape with scalpel blades - they are not designed for such forces. Nonetheless, we all do it sometimes, but in my experience these blades have always broken at the eye first, and stayed attache...

Re: What's the correct drill bit?

I would go with a Forstner bit, equipped with a shank extension to reach the four inch depth. If you clamp it up securely on the drill press, you could possibly hog out most of hole with a smaller bit - e.g. a 1/2" or 3/4" bit, and then without disturbing the setup, chuck the extended Forstner and f...

Stephen, I still do it with the Mark I brain and eyes, and use a kitchen oven thermometer with a cabled probe, costing about $10-15.
