Measuring threads
What's the best way of measuring threads. Thread wires of a thread micrometer and how difficult are they both to use?

If you can afford them thread mics would be preffered over wires,a has been noted in previous posts the wires can be awkward to use.
The thread mics only require you to position the anvils on the threads correctly.

Wires are something like $25 a set... And can measure everything..... Thread micrometer will go in 25mm increments plus has to have a swag of anvils to go with it, 55 degree for whitworth and 60 for metric and unified.. Different anvils for different ranges of pitches as well...
Gold, the colour of choice for the discerning person.

Hi Andre,
Making my plug gauge was the first time i had used thread wires. They are not that hard to use, as R.C said in the latest project thread, you just need both hands and a tail.....I'm thinking a simple block made from a plastic could really help to hold the wires in place. The only one problem i see with them is when measuring course pitches, the wire sets say they can measure to 3tpi, but a mic anvil won't sit on both wires at such large centers.
The CDCO ones are only $7, and the quality looks good.1915 17"x50" LeBlond heavy duty Lathe, 24" Queen city shaper, 1970's G Vernier FV.3.TO Universal Mill, 1958 Blohm HFS 6 surface grinder, 1942 Rivett 715 Lathe, 14"x40" Antrac Lathe, Startrite H225 Bandsaw, 1949 Hercus Camelback Drill press, 1947 Holbrook C10 Lathe.

I ended up buying an American made set of thread wires and a 2.5 inch sine bar. I purchased them from http://www.fishermachine.com the wires were $25 and the sine bar was $38.

Just ran into this link while looking at metrology stuff on PM, may be a good idea if a suitable rubber profile can be found. http://www.f-m-s.dk/3%20WIRE%20HOLDERS.pdf

I have a set of these. A pair of them costs around 80 €.
I got the complete set for 25.- €, NOS. He didn't know what he was selling to me.
They slip on the anvil and spindle and are relatively easy to use.
They also do have a calculator online to get the measured pitch diameter.
Whenever I read something from Gordon, I'm close to getting a heart attack. The contraption he described will not work that well. Either the wires will be bent, or they will not slip into the Vee correctly or they will fall out. You have a measuring force of just 1 N.
Put a dab of grease on the thread and fix the wires with that. Better than wasting time cutting rubber.
