Quote:Darren, I noticed that you mentioned getting a set of telescoping gauges. Those are definitely cheaper than a set of inside micrometers, until you add the set of outside micrometers required to use them. It's extremely difficult to measure a telescoping gauge with calipers and I wouldn't recommend it. A companion tool to go with the "T" gauges is a set of small hole gauges. I like the ones that have a flat end so you can measure shallow holes with them.
Tom,
I just bought a set of starrett telescoping gauges and used them to measure a hole I was boring on the lathe. I did use my calipers to measure the "T" gauge (I have outside mics but didn't use them) and wonder what the downfall is in this technique. I was enlarging the hole in a small pulley from 1/2" to 5/8". The previous pulley i modified I had to use my caliper which was very difficult to do and resulted in my purchase of the "T" gauge.
