Inclusions bending questions

[Haynie]

What do you folks who put inclusions into your blanks use as a bending form?

You might have to define "inclusions" I think you might be referring to coins and watch parts or others that are thinned and bent around a tube?

If that is the question. Then any dowel of the proper dia. with some materials there will be spring back, so you bend it to a smaller dia, so the spring back is only enough so the fit for the adhesive is close.

Yes, that is what I was talking about. I tried rolling a thinned coin but it got scratched up. I thought pressing would be a more shine friendly process. I was just looking for options.

I drilled a piece of 1" corian with bits that match the tubes I am using then cut that in half along the drill holes. I then use a clamp and a transfer punch to bend the objects going in. Some of the embedded items benefit from a bit of heat before bending...enough to soften but not discolor them.

With the coins annealing would help you can always try it with un cut coins to see about color changes etc.

How do you get the coins thin enough to bend? Grinder? Sander? Turning?

I used a disc sander.
Used a forstner bit slightly larger than the coin, about half the depth.
made a holder (I used a scrap piece of soapstone) and used that to
push the coin up against the disc. If you take the time to square up
the holder and true up the disc sander table, that helps.

Hot glued mine to a piece of wood and used a belt sander. I was surprised at how clean it came off after reheating the glue with a heat gun. I like New London's idea better. I had one come off the block and imbed itself in the dry wall behind the sander. Kind of scary.

Ah. Time to hire an assistant. :tongue:

 

[Haynie]

Then they would want workman's comp.

oh. So you hire those assistants that can talk and think.
