Not my idea, but it works REALLY well for sizing bullets.... Today I mounted my Lee Press upside down on my bench....
I used 1/4" ready rod to make the long bolts, and 1/2" pipe for the standoffs.... The only modification needed to the press was to grind part of the webs away on either side at the top where they interfered with the standoffs.... In addition, I added a lead weight to the handle so that it doesn't rise up when you let go of it.... This keeps the ram up to give lots of room above the sizing die for loading the bullets....
You simply drop the bullet into the bottom of the NOE sizing bushing (which is now on top of the die) and lift up on the handle.... The sized bullet drops into the plastic tub on a shelf just under the press.... No more working blind, upside down, or having the bullet enter the die crooked, or pinched fingers....
