Re: Tap/Drill Chart

take the OD of the thread and subtract 1 pitch for the tap drill diameter 1/4-40 tap drill = .25 - 1/40 7/32 is close enough since I don't have a 1/40th of an inch drill worked for me for 50+ years Yes, the entire Starrett chart can be replaced by that one, easily remembered equation. TD = MD - P T...

I seem to remember hearing (years ago) that the platinum standard that defines the Meter has changed in length since it was manufactured. So now there is a standard based on some wavelength of light. Am I remembering this correctly? ~RN Even if the erstwhile platinum standard maintained its length ...

Re: Gage blocks

Thank you all, especially to SteveM. That sounded like good advice which made good sense; the least number of blocks, the less any deviation. I learned something new today. Thanks! The trick now is to decide which blocks to use to obtain a desired size with the minimum number of blocks. Starrett ha...

Decimal error. Read 0.011 degree error for a 0.001" over 5"
I think the use of bold type is inferring that you are incorrect about the error being less at high angles, because in fact, it gets worse as the angle increases closer to 90.

Exactly!

With a 5" sine-bar the error at small angle is 0.1145 degrees for each 0.001" error on the block. At high angles is even less.
Want to try that again?...
