Reply To: Measuring RPMs…

Tom,
it just so happens I have one of those! It came in a box of bits I bought at auction and I had no idea what it was until a friend told me. It does the job and lets you know what the rpm’s are but as David says, over time you will just know where you should be with regard to speed. In the meantime it will be quite handy and should speed up the learning process as long as its not too expensive.
Paul.
