I have a friend that bolted down 3 short pieces of 2x4's to form a u shape. He then bolted his basic press two the 2x4's. The primers fell into the u shape and he sucked them up with his shop vac. Worked for him. I use a portable block of wood that I made along with a hammer and punch. I can de-prime in different places at my convenience, usually while watching tv. Primers fall into a catch that I just empty into the garbage can.
