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

Assuming you mean "thread tap", it is for cutting new threads in a hole.
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.
How do you clean rusted thread on galvanized pipe?
I find a wire brush is usually enough to clean threads.
How can you get a new PVC screw cap to attach to an old worn and rusted threading on a pipe?
Use pipe die on worn threads if you have enough room for die to fit. If not, clean threads with wire brush.
How do you stop hot water relief valve from leaking around threads on new installation?
You have to use pipe dope or Teflon tape on the threads before you put it together. Pipe dope should fill the threads and if tape is used, 3-4 layers of tape should be enough.

How do you re thread a bolt?
if the threads are just slightly misshaped, than you might be able to run a grade 8 nut over the threads, this will straighten them out well enough to use in most applications. (make sure the nut starts the threading straight or you will crossthread the bolt and it will likely be junk) if the threads are severly damaged you will need to buy a "die" and run the die over the bolt. a die looks like a large nut but instead of having smooth threads on the inside they have cutting edges. these can be bought at any hardware store, and they can be kind of pricy. ---- unless this is a special bolt that you cannot find anywhere to replace it with or it is expensive to replace, i would recomend just buying a new one.

Would a screw with more or less threads make work easier?
It is easier. The question is not complete enough to be answered. The word EASIER needs to be further defined. so the question should read: What is easier to [add information here]; more screw threads or less screw threads?
What is internal impedence of digital multimeter?
A: [practically all commercial digital meter have a 11 mega ohm input impedance but there are special meters that can be used to measure leakage current and they have impedance high enough to measure nano amps. Even an oscilloscope will have these kinds of impedance such that the reading is not influenced by external loading
