Having built the gauge to test the accuracy of the setup of my table saw, I might as well get on and use it.
The blade (of which I forgot to take photos) varies from front to back by about 0.2mm. That sounds like it should be correctable, so I’ll have a go.
These are from the right-hand T-slot to the left hand side of the fence.
Looks like it bows away from the slot (and therefore the blade) by about 0.2mm in the middle when compared with the ends? I’m not sure how I deal with that for the time being.
And the left hand T-slot and right hand side of the fence.
Looks like that side is also bowed, but more out at one end than the other.
I’m really not sure what to make of this for the moment. I guess the second set of measurements aren’t a big deal as I almost never use the fence on that side of the table. A bow of 0.2mm doesn’t sound like a lot, and in reality probably isn’t, but it’s enough to show in a joint.
More consideration required.
