Threading die starting method
When cutting male threads, the first few threads are not well formed until the die get a good grip on the part to pull itself forward.

I use this method to cut good threads from the beginning.
Mount a headless bolt of the proper thread in the tail stock chuck. Mount the part to be threaded in the lathe chuck.
Place the die stock on the part and thread the die onto the bolt mounted in the tail stock.
