Lots on eBay Lately
Maybe it is budget cuts, I don't know, but lots of AFM8's out there right now. Hard to get one less than $100. Pass on ones that look very used. DMC will rebuild for $100 flat fee.
Positioners - happily i got two positioners with mine, but neither was of any use, so I took one apart, studied the function made precision measurements and made an insert for a K13 in about 30 min on my lathe. I used small dia solder to establish the crimp depth and it works on dSub's great! My plan is to make new inserts for other pins if needed. They must be very precise. .0005" to dimension or better!
BTW - they can not be fully dissembled, or not without removing some press pins. I sent a rough one back (eBay) since it was not the same as the picture, but the seller happily and rapidly replaced with another one posted. The first one did not cycle smoothly, it had sticky regions. Maybe it stuck in place and that is why it was beat up.
+1 on steinair coax crimper - also they have replaceable dies that handle PIDG connectors. Good cost saving, quality tool.
