Well done Larry,

Unless turning loads of threads many professional machinists forget how to use the thread dial properly, I confess that unless doing a production job I use the "Reverse clutch method" where the clasp nut is simply left engaged and you simply wind the tool back out of way of the thread and then reverse the spindle rotation which "rewinds" the carriage, so the tool, back to the start of the thread and in the correct position every time.

It's not that I'm lazy, it's just that it removes one possible error from the list of a million things that can go wrong when turning, Yes it takes a little longer but so little longer that unless it's a "ten off" or more I don't think it's worth doing it any other way.

So that is external threads mastered,
time to have a go at internals

Despite the fears that most folks seem to have around internal threads it's really no different to external just the spring in the boring bar to contend with and of course most folks never single point turn internal threads down to 3/8" the practical minimum for most people is probably 3/4" which is also luckily about the same diameter that taps start to get ridiculously pricey.
