I didn’t use any of the parts in the Stanwood kit. I wanted to preserve them intact for possible future options. The anvil: Get an old 7/64 drill bit and break/cut 1/2” or so off the butt end. You’ll use this short end later. I shaped a piece of 1/2” baltic birch plywood to fit in the base of the press and epoxied the bit in one end, upside down, so the butt end would stick through the little hole in the base. On my last set of hammers I pushed the bit through the wood, so I guess I’ll do it over in metal. I have about 3/4” of bit sticking out from the wood piece. The ram: Your press will come with a pin punch and a small hex head machine screw for inserting center pins. Both thread into the ram. Get another hex head machine screw that size, drill a hole in the center of the head, and epoxy the short end of the bit into the screw. I have about 1/4” of bit sticking out of the screw. When you get it all together, just make sure you have enough space between the ram and the anvil to get a hammer in between, with some to spare. The handle: The original handle is a piece of 3/8” or 1/2” flat steel stock. I broke mine on my second set of hammers, right at the hole where the ram attaches to the handle. I made a new handle from 3/4” flat stock, 1/16” thick. It is holding up well. I cut a 3/4” dowel in half and attached it with screw posts, like a butcher knife handle, then rounded the end on the grinder. All the press parts are held together with roll pins, so disassembly and assembly is pretty easy. The main change I made in the handle is where the ram attaches. Since the handle moves in an arc and the ram moves vertically, the contact point moves back along the handle when you push down. The solution in the original handle was a big hole, which left very little metal at that point. That’s fine for center pins, not so good for a swaging press. I used a smaller bit and a really small file to make a horizontal slot for the ram attachment pin, preserving the handle’s strength. If you have access to a milling machine, that would make the operation a lot easier. I also had to round off the pivot end of the handle for clearance in the yoke where it attaches. I hope this is reasonably clear. If not, let me know and I’ll bring my camera in tomorrow and take pictures. Regards, Ken Z.

I went ahead and ordered one...

You have to make your own. Stanwood uses a benchtop drill press. I’ve only got my big drill, so I modified a center pin punch, Schaff #178, p. 44. This included making a new handle, since the old one was too wimpy for lead. Some years back John Hartmann described a press he made for installing backchecks, out of a device that converts your hand drill to a drill press. It looked cool, so I kept the link: http://www.grizzly.com/products/item.cfm?itemnumber=g8061 I suppose you could make a chuck of some sort for that as well. Regards, Ken Z.
