Which is made from drill rod, untreated. It looks like I am stuck with the 3.5mm allen socket to drive this.
I see some carbide broaches on the net, mostly for quite heavy prices. 1. My mill hasn't the ability to drive even a wobbler as its all tapped out at about 150 lbs of push. 2. I have a live center for this mini-lathe, and if I really really snug down the tailstock clamp, it might make 200 + lbs of push. Likely not enough to push it straight in. But what if I drill a dimple in the end of the key to keep it on the point of the live center, with this screw screwed into a piece of scrap centered in the chuck, drilled with a 3.5mm bit 12mm or so into it, then place the sharpened allen bit piece between the screw and the tail stock, and offset the tail stock several thou. Starting the spindle would provide the wobble needed to do it one corner of the wrench at a time. Is this workable or do I need magnitudes more pressure and a carbide cutter? Thanks Guys.
