I build my own weight bolts on a 11 x36 Logan lathe which sets unused in the pro shop room of my PH when I am doing counterman time. I stick a length of all thread in the spindle...face it off...bring up the tailstock... drill and tap 10/32 thd... back off tailstock... mount vertical dremel with cut off blade and grind horizontal slot across the face of the allthread. Works well and looks pretty but it takes to many manual passes to grind a deep enough slot for a screwdriver blade. Gotta be an easier/quicker way to machine this slot...saw blade style cutter or what...how do you do this...tell me somthing so simple , quick and pretty that I will really feel dumb. Thanks Ken Ken.
