I believe you are talking about dies and taps- which have a sort of inward cut Maltese Cross appearance, or cloverlead appearance in the stock, which is placed in a holder- and the job begun.

Do you need s special tool to cut bike spokes?

Depends on whether you're talking about cutting threads in them or merely about cutting them off. Cutting threads in the does require a special tool as spoke threads aren't cut but rolled. Using a die cutter is awkward and likely to result ina weaker thread. If your intention merely is to cut them off then any thread cutter strong enough to deal with steel will do the job. Don't get one intended for electrical (copper or aluminum) cable, as the steel spokes will damage those shears.

When lathe cutting threads how do you measure external screw threads to know they have been cut deep enough?

The only sure method is to have the appropriate internal (female) thread eg. a nut available and to try this on the cut thread. If the fit is too tight then another cut or pass must be made on the lathe. If you are cutting both male and female threads to match then cut the female thread first and use it to check the cutting of the male thread. Submitted by Bill Lavery


What is meant by pitch measurement in lathe?

Pitch measurement refers to the distance from one thread to the next when threads are cut on a lathe. Different threads have different pitches and a lathe can be set to to cut to any specified pitch. This is achieved by selecting the pitch and engaging the lead screw on levers located on the headstock, then engaging the half-nut around the lead screw from the apron. With the correct threading tool inserted threads can be cut into the workpiece.
