As mentioned in a previous blog about the arrival of the mini-lathe, my first project is a cutoff disk mandrel for a dremel like drill.
For this I needed an M2 tap and die set which arrived in the post on Saturday from SFC-Tooling. The body of the mandrel caused no problems and was machined and tapped. The screw on the other hand caused a problem for my first tapping attempt.
I have discovered a technique from Fadmucker for making such small threads. He’s made a special die holder with a pre-drilled M2 clearance hole. This means that the die is held perpendicular to the item being threaded.
