Set-up blocks

Here's an idea for set-up blocks to use for tablesaw or router table settings:


Go to your industrial supply dealer and purchase a variety of lathe tool bits.

They come in a range from 3/16", 1/4", 5/16", and 1/2". Many are ground to size and

are plenty accurate for woodworking settings. Prefer the ground bits.Smiley Happy

(I wouldn't rely on them for calibrating calipers or micrometers though.)Smiley Sad


I was also fortunate enough to be able to get a set of precision pin gages (.060 -.250)

by .001" increments, and a small assortment of gage blocks when the manufacturing

plant I worked at closed down. These items have served me well.Smiley Very Happy

But the ground tool bits are invaluable.


Rockler sells brass blocks, but are advertised for an accuracy of +/- .005" this doesn't

sound too accurate to me. A review comment mentioned using them to check the

accuracy af a caliper - I don't recommend using them for that degree of accuracy.

Why is there enough time to do it over, but not enough time to do it right the first time?

Re: Set-up blocks

You need to move this to shop tips...

It's a good one...


But I have a question...


.005" = 1/200th's of an inch...

Working that tight with wood consistently is nearly impossible...

Just working at 1/64" with regularity is an IRL achievement..

this would have been the week that I'd have finished chewing thru the restraints...
if only new layers hadn't been added....


Forget the primal scream, just ROAR!!!
