Depending on the shape of the shaft used to extend the force to what
you are using the press for. With round or half round ends you can
use a close fitting dia. section of gas/black pipe welded to a plate
to attached the stamp or impression die to. To keep it tight and
attached to the shaft, you can drill and tap a hole in the pipe
section for a 1/4" or 5/16" screw with a hex head( makes it easier
to get off with a wrench after you over tightened it).
You also can use a pipe that fits tightly to the corners on a square
shaft. Put a screw in one side to hold it in position will in use.
It should look like an upside down capital T with the flat part the
mounting surface for the stamps or impression dies. You can mount
them to the plate with bolts and hold down clamps or have a pipe
section centered on each one and welded.
For short/ limited number of item runs you can do the same thing out
of wood and glue and screws. The only thing you will want a thick
layer of plywood as a base 1" or 1 1/2" thick can be glued and
screwed of thinner sheet.
Then you drill a hole centered in the back of the stack. Some find
it helpful if you glue a couple layers to drill the ram hole in the
back of the plate keep the hole size as close to the ram shaft size
as you can. When you try it if it wobbles/dances around to much. You
can use a low temp melt hot glue to fill the voids around the
ram/wood. Here are a couple more links for jacks and rubber casting
The harbor freight is a good source on info because they have most
of the instructions on line they also now have a 20 ton
