having seen a number of screw cutting devices offered and now having a real grasp of how they work but put off by the price I have decided to make my own. The device itself is straight forward enough and making the cutter straightforward once I establish a few things.
I am assuming the following
1) TPI the same as the spindle nose thread makes it possible to make screw on wood chucks.
2) the total length of thread that would need to be turned probably no more than length of the spindle nose.
The diameters required to be turned are from max lathe capacity to the smallest likely to be used, The dia of the cutter must be smaller than the smallest dia thread to be cut so how small would the experienced turners suggest for a start. After all I can always make a smaller cutter later if required, what is the dia of and how many teeth are there on the proprietry item that you have.
what drawbacks have you found, what changes/ improvements would you like to see.
