Ooops I miss spoke.
I didn't use wood putty, (on left) that is obviously for just filling nail holes on trim etc.
I used plastic wood (on right) which will fill and stay put for ever. On mine I also have the drum wrapped in Velcro that would keep anything loose from coming out. This stuff gets so hard I sometimes start sanding on it before its completely dry.
Not sure if your interested in making your own bending machine, but its pretty easy, and can be done cheap.
Mine is just scrap plywood, springs I've collected over the years, cauls made from scrap, aluminum tube ($12.00 worth per machine) old quick grip clamps from garage sales ($5.00 for two) and a Watlow silicon heat blanket (same company that makes them for the luthier supply companies) This one is for heating or keeping 5 gal buckets thawed or warm. It comes with a built in rheostat/thermostat that will not let the blanket get more then 350 degrees. I've checked and it does not get any warmer than that, plus it works great. Found it on Ebay for $10.00
