« Part 14: Fast Accurate Louis Cubes Part 15 of Simple Jigs and Techniques series Part 16: Re-design of my Veneer Guillotine »

I’ve read about this technique in Pierre Ramond’s books but never had a need for it before. I wish I had tried it out sooner. It is an amazing little technique and so easy that my first attempt was good enough to use and I had four rings like the one In the photos done in about a half hour.

The pipe (or bar) needs to be about 200 – 220 degrees F. I’ll let the photos explain the procedure.

Here’s the setup. A quick online search will turn up this style of jig in several places.

My first try, a ~1” coil, just the right size for my rings.

Cut to size

Glued in .....

.....and sanded off

Next I tried a 1/4” punch shaft for some more intricate pieces I will need tomorrow.

Too easy! You just gotta try this!

Thanks for looking in,

Hey that looks like a sweet deal, How do you regulate the temp.?
I use an old curling iron that my wife used to use when her hair was longer, and an old electric soldering iron (not gun) ... Looks like you are using some 1/8th inch stock, I bend 1/16 and 1/32 stock for string inlay usually holly.
I have found that some woods bend easily with heat and some are just to brittle, and some just want a bit of moisture added.
Thanks for the tip.

I’m using 1/16” maple, wet. The pieces are in water in the milk jug in photo #1. I just set the torch at dead low and check it with water drops. I will be experimenting with some others. This is fun.
