Hey guys, I still have had no luck finding a real model number or markings on this thing, No parts that look familiar either.
I've taken some measurements and have sterted to turn down a phillips bit for a screwgun. the starting diameter and the groove in the shank of the bit to lock it in the apex are almost identical as the diameter of the pin and the slot it needs. Only hard part is turning down the nipple for the pin. I have been spinning the bit in a drill motor and grinding with a dremmell. stop and remeasure. I'll let ya know how it goes. maybe even figure out how to post a pic.
thanks
