Making a new back plate to my 40 inch lathe. Managed the internal thread (68 mm thread on spindle, that is 2.68 inches dia.), had luck, seems to fit.
But I need good ideas on how to put a nice beginning and end on the thread. Don't have a Bridgeport, only a shaper - and I don't fancy using the shaper for this, although it presumably just might be done. Screw-up expectancy factor too high.
Thinking of using a cold chisel, after all no-one will see the result when the back plate is in place. But I will know it's there and that it will be ugly as h***.
Any ideas, fellers?
Regards, fusker
