« Part 16: Better Dial Indicator Mounting Part 17 of Delta Mortiser 14-651 series Part 18: Table with tool »

I got the dial indicator mounted and it works good. A 10 mil movement isn’t much on the knob, but it’s pretty clear on the gauge. And I found when a mortise is off by as little as 20 mils it shows up on the joint if the pieces are the same thickness.

Mortise 0.377:

Two sides 0.177 and 0.180:

That is 10x the accuracy I was getting by sighting it.

Here’s the pudding…

Nominal values:
Thickness .750”
Mortise .375”
Cheeks .1875”

Reality
Thickness .720”
Mortise .377
