Tricks of the trade

 

Here tip that make life easier.?
Threading and the lack of Threading dial.

The lathe I used have a lead screw of 4tpi.
I did not need a Threading dial? for 4. ,8 , 12, 16 or 24 tpi did not need a threading dial fast and easy threading.?

This works on mini lathes too.
16tpi lead screw 16 or 32 tpi? do not need a threading dial
1.5mm lead screw 1.5 or .75 mm
2 mm lead screw 2, 1 or .5 mm

So on projects and doing I try pick a thread that is easy.

Thank you very much for the idea.

[ Easier to set up than a four jaw chuck if you have no virtually no experience of same. Equally - Easy for those who have I4J skill. ]?

For blind threading RH use reverse and cut from back side.?

You use a carriage stop move carriage to stop and ingauge the haft nut and start in reverse.? Now cutter will back out hole.?

Note this only works with a threading dial or it same thread as the lead screw.?
It does work use a dial indicator and manual turn the till at mark on dial indicator. Works about same but slower
