Default Tolerance!!!!

Not as in respecting opinions but as in how close is close tolerances

A link by RJM in the thread below shows how to use playing cards to measure height adjustments on a reversible glue joint

http://www.routerforums.com/router-b...ing-miter.html

so I put a deck of cards in the shop and use them frequently. For grins I placed the deck in a squezze clamp an measured the deck thickness divided by #of cards and came up with each card equalling .011 thousands

I checked card against feeler gauge and verified the math so know i have an inexpensive feeler gauge that can measure what I cant see or feel

Slick stuff Bill! I use all kinds of different 'objects' to measure other things with tactile touch, which in my case is far superior to my eyeballs making out the lines on a ruler. Oddly enough, especially considering my appreciation for poker, using playing cards had simply never occurred to me.

Thanks for the tip!

Hi Bill

May I ask why you want the fence off the table top by 1/32 or so you don't want any space under the fence, it's a good place for the chips to get hung up at and move the stock away from the bit..

Just asking Bill

Bob

The sub face was slotted prior to assembly. The MDF fence face material was placed at that height and marked for thru bolt location. after being installed it rests perfectly flat on table and slides wonderfully without any bolt snags That 1/32nd was perfect for achieving accurate results
