Here is what the diamond polisher looks like so far. The ten inch drums are laminated MDF, with a half inch layer of neoprene foam backing. There will be eight ounce leather over the foam with 14,000 grit on one, and 50,000 grit on the other. Woody The basic drum  The drum painted, and backing applied  |

How big are the diamonds you have to polish?!? Man, you'd have to have a BIG woodworking shop to build something like that! ..... Oh wait... It looks like you DO!  Nice work, are you going to overlap (angle cut) the leather 'belt' edges? When do they go on sale?  Dr Joe . |

Dr. Joe:
The shop is large enought to build up the 25' boats. I did do one at 31' but that was a real pain...the shop is only 32' inside.
I am toying with the idea of making leather belts for three inch expando drums. I first want to see if my joining method holds together. The belts will be scarphed, and glued.

Woody
Nice job looks great, should do some good work. I see you are just like the rest of us woodworking people. Never throw a piece of scrap away, might need it sometime.

PS. You might want to feather the edges on the leather where it overlaps. One directional, but it won"t snag and come apart.

Because this thread is featured on the new and improved DIY Lapidary Equipment page I am working on, I Updated this thread to provide a better more complete conclusion to the project write-up. Woodyrock created two separate update threads and I have quoted them here including a lot of really amazing pertinent to the OP - Tommy Quoted from: forum.rocktumblinghobby.com/thread/49590/drum-framesSeeing as how the weather was wet, and cold today here in the great Pacific Northwest I decided to light off the steam box, build a fire, and bend some drum frames of of some air dried White Oak. You will readily see this is no high tech operation but it does work. The steam box itself is a length of fibreglas pipe, the source of steam an old pressure cooker sitting on top of the crab cooker. The drum frame former is just a 16" wood disc bolted to a saw horse so it can rotate. Here is the steam box  This is the frame former  This is an hours worth of bending setting up.  Quoted from: forum.rocktumblinghobby.com/thread/50240/drumsWell, you saw the drum frames I made a while back, so here are drums. My, her brother, and I got together, and took a class at a nearby reservation on drum making Saturday, then today, we made more drums at home. During the class, a Skokomish weaver show us how to weave the handles which looks a lot better than just plain wrapping them. Five of the drums are elk skin, one of which was neck material which is thick, so that drum has a very deep voice. The sixth drum is deer hide, which is much thinner than elf, so it has a much higher pitched voice. Punching the lacing holes  Lacing the skin edge  Getting the skin on  Lacing the drum  Weaving the handle  Finished handle  Finished drums..one is was being played when I shot this  |
