Thanks Saltfever, but my understanding is it's a bit more complicated. In that in order to have the correct spacing of I think 2" between the shafts I'd like to get the same gears as they use on the plate type/HFT beaders. I'm trying to keep things somewhat standard so I don't have to do more work on the other end. Like making up for the odd diameters of the dies. Do you kinda get where I'm coming from here? I was hoping someone could either tell me what size/pitch the gears were in their beader and I could try and find a source. Ultimately I'll bet trying to make a one off I can't buy the parts for what these heavily subsidized Chinese tools are sold for. But it's a good mental exercise and might ultimately ease the sting of not buying that HFT I saw and just bite the bullet and buy the Amazon beader.
