This is an update about an issue that I faced, this has to do with smallest crimping hole, this is for central pin of BNC connectors.
Recently I made two BNC high quality cables with Amphenol B1121A1-ND3G-1-50 connectors. http://www.ittsb.eu/forum/index.php?topic=1144.msg2928;topicseen#msg2928
And I discover that this ratchet tool small hole this is 2mm wide (compressed) and also specific Amphenol BNC center pin this is 2mm.
Therefore this Ratchet Crimping Pliers it is unable to crimp specific BNC center pin.
My solution were one work around, and this was to add one small piece of hard copper cable in this gap, so this to compensate
and make this hole smaller.
My work around worked, but after its crimping session I was forced to renew this addition filling (small piece of hard copper) with new one.
I did manage to crimp all my four connectors, by using patience and caution, but for productive work, I would have to characterize this tool as FAIL.
