I have the same Arbor press. I disassembled it at the end of the ram I drew an X, and drilled it out. I went to Harbor freight and bought a package of their hi powered magnets, stacked 2 in the hole. I know the flaring tool your talking about. I used the hole in my press for my Kydex dies. I also drilled the Arbor plate between holes and added the same magnets to hold the lower die. The dies slip in and out easily now. The ram will drill easily it is made from cast iron.I have a HF arbor press and now have a need or would like to have a flaring tool attachment for flaring the ends of tubes for knife handles. Any of you guys have this attachment or advise you can share. The ram arm on my press doesn't have any threaded hole to mount one.
