First time using feeler gauge in shop

[Matthew Curtis]

I made a crosscut sled today and used my feeler gauges for the first time in the shop. I got my fence to .0025" over 88" using the five cut method.

I was wonder how close others are and are my results good, bad or ugly?

That's incredible. Are you sure you didn't type something wrong? I want to see this 7' sled.

Verry funny
Using five cuts all you need is an 18" square to compound the error to get what I got. Unless I totally missunderstant the five cut method.

[Van Huskey]

The last one I did (which I still use) I started with a ~24" square piece and was able to get the 5 cut error down to just under .001" (using an analog caliper). Before adjustment, my error was about .003".

[Cary Falk]

I guess I am used to seing it stated across the 18" dimension and divide the error by 4. How did you use feeler gauges? I have always used a caliper.

I'm curious about the feeler gauges too.

I watched the wood whisper video. He used a feeler gauge to make the adjustments. Placing a stop block against the fence, unscrew, then adding the thickness of a feeler gauge between the block and fence would make the adjustments before rescrewing the fence.

OK that's standard after measuring the cut and doing the math to determine the error in the fence. I thought you were somehow using the feeler gauges to measure the error. I haven't watched Marc's video on sleds so I don't know if he goes through the math to get it exact. You may want to track down William Ng's sled video to determine if his process is different from Marc's.

I got mine to 0.0000000005"

Anything less in woodworking just ain't gonna cut it.

Fully agree. Please let us maintain a high technical level here! ;)

Wood working precision

1) Measure with a micrometer

2) Mark with chalk

3) Cut with an axe

Simple really...............regards, Rod.

I don't know about anyone else but I feel a little inadequate now.

Better have at least 2 sleds. One for the heating season, one for the AC season...and maybe one for in between.

It's a pain to have to read the calibration instruments through a telescope from 100' away behind a heat shield, but so worth it. :D
