Title: Starrett V-Blocks
Post by: toolznthings on July 17, 2018, 09:02:13 PM
If you happen to want to add additional Starrett V-blocks to the ones you may have, be aware that they are sold in match pairs and additional ones won't match.
The two pictured are marked with " 150 " so they are a set. Use to be a note in their catalog that more than two matching were special order. Maybe that has changed ?

So how much would another set vary buy 0.0001" or less?

I had extras and they were not close at all. Your results may vary ?

How much is "not matching"? I couldn't imagine most home hobby machines noticing the difference.
