Pneumatic de-rimmer in the works....

Hey fellas, been working on my derimming press. I decided to covert an old Rock Chucker. I lucked out because the ram on the air cylinder is the same diameter as the RC ram. In the picture the ram is at full stroke. I have an adapter that will screw on the end of the cylinder's ram and it is threaded on the opposite end to accept threaded base punches. A special thanks goes out to Roy for making the adapter for me. The adapter should be here in the next day or so, but Roy did send me some pictures.

I also have to drill holes in the linkage arms so I can insert the pins on each side that will anchor the press to the air cylinder. You can see the pins still just sticking out the side. After that a couple air fittings, some line, and a some sort of valve and I will be in business.

This is a close copy to Lafauns derimmer. Thanks for the idea!
