Single point threading problem

I just back the cross feed out, engage the half nuts and let the carriage travel till the tool is over the tread. Stop the lathe, now use a combination of compound and cross feed till your into the cut thread. Back out the cross feed and start the lathe, now slowly bring the cross feed back in till your cutting. That depth on the cross feed is your new setting as you back out and return for subsequent passes.

Yep, same method I've always used - even works for blind-hole Metric-fine internal threads on an Imperial lathe (eek!) - and a bit quicker and easier than stripping the forks off the bike (and stripping the fairing, brakes, mudguard and handlebars off too so I can get the forks off - Grrr...) so I can try the steerer thread in the new custom headstock-bearing top-nut while it's still in the lathe... If only I had a M22 x 1.0 tap, eh?
