Re: Makers Knife

If you want to make your own knives or reconfigure old knives, that's fine. It's quite easy to make good knives from O-1 tool steel. The key is to achieve the correct heat for hardening and then tempering them. I recently purchased some precision ground O-1 stock from WTTool.com and the hardening an...

Re: an 'air-fume ejector' for a spray booth?

A manometer for calculation of airflow might be useful for the development.

an 'air-fume ejector' for a spray booth?

Obviously, this is an old-timely illustration of a forced draft spray booth, but I think the concept may work just fine. Any opinions?

Re: safety shoes for woodworkers

It looks cute but the question is how comfortable it is on the feet? I did need to carve out the instep a little bit to fit into them, but once they're on they aren't floppy, and they aren't heavy. Actually, they're quite comfortable standing still, or walking outside on the lawn - warm and dry. On...

shimpo pottery wheel for spinning radius dishes?

Hello, Someone gave me a Shimpo 21 variable speed pottery wheel. Our House Artist isn't particularly interested in pottery (busy with glass & painting), so I'm wondering if anybody else ahs repurposed it by placing a radius dish on the 12" platten. It draws 400 watts and spins at 0-250RPM, and seems...

Re: safety shoes for woodworkers

The shoes are quite old but show no signs of cracking. They're made from watersoaked poplar, and were hand carved inside with a spoon auger and hook knife. The outside was shaped with a block knife which operates like a papercutter. Here's a video: https://youtu.be/dt5BLJhiMO0 They're pretty comfort...

Re: Dust-mageddon!! Dust bag attachment help needed

I bought bungee cord at the hardware store, guesstimated the desired stretch, and then inserted the ends of the bungee cord into a thin-walled brass tube and punched the tube to lock the cord in place. It worked for me.

safety shoes for woodworkers

Hey, my 93y/o neighbor (born in Germany) gave me a pair of shoes. They're actually pretty comfortable but best worn outdoors in the soft earth.

Pretty natty, eh?

Re: Handcrafted Luthier Tools

Like many others, I've made a number of tools - a frewire bender, fingerboard slotting fixtures (standard and fan-frets), and maybe few other things that I can't remember. Just search in this forum and the old library for my name.

Look carefully at the cross-sectional shape of his cutter. It's feathered for clearance on both sides.

Re: The scorper, a rosette channel cutter

Bryan, One way to deal with that would be to make the scorper with cutting edges on both ends. One would be as in the video. The other end would be modified by hollowing out the center of the edge with a file to form two spurs on the outer edges. The cut would be started with the modified end to sco...

Re: Woodworking Workbench

I think you'll end up building more than one. And they'll probably mutate as needs dictate. Many of the features of a traditional cabinetmaker's bench may or may not be useful, but you won't go too far wrong. Lately I've been admiring Paul Sellers very practical advice about workbenches and handtool...

Re: One of those offbeat ideas - a d/c-powered pipe organ?

Hmm, the first question is to determine the pressure & maximum flow rate after determining how many ranks of pipes are desired. Maybe a simpler way would be to make a mechanical bleed valve, with the issue of keeping bleed off quiet.

One of those offbeat ideas - a dust-collector-powered pipe organ?

Every once in a while, a semi-crazy idea pops into my head. I was thinking about one of my high school teachers who had built a new house for himself - around a church pipe organ that he'd bought (Really!). So it occurred to me that it might be possible to build one using a dust collector blower for...

Re: Drum sander attachment for my outside sanding lathe

Bob, do you get an even thickness with your rig? If so, it's easier to build and set up than the one I built (in the library) which gives good results but takes time to set up and adjust (I like to do a woodturning too).
