Extra versatility for when I add the turret press: the bench plate kit allows presses to be swapped out in about a minute by loosening some screws. Remove the clamps from the plate and it’s a mostly flat surface that’s left…or I can just undo the C-clamps to move all of it out of the way to use the workbench underneath.
The metal plates Lee sells for use with its presses don’t work with the older (non-breechlock) Challenger press. Two wooden blocks are included with the kit, intended for use with other brands of presses; I drilled one for my press. The metal plate I have will end up bolted to a Classic Turret Press; I won’t need to buy one with it.
