So, last night I spent an hour or two trying to invent a jig to align the various parts of my table saw with the new dial indicator I received from Amazon. This is what I came up with, which seemed pretty solid:

I think it would be fine if the miter sled that came with the Bosch 4100 table saw wasn’t such a piece of crap. There’s somewhere in the range of 0.007”-0.012” of play when the sled is in the left miter slot. It’s nearly as bad on the right slot. I tried shimming the left side of the sled’s slider with 3 layers of clear packing tape, and it made it a little better, but there was still play. Sometimes I would get readings of 0.002” from front to back hitting the same spot on the saw blade, sometimes it was more like 0.008”. Plus the dial indicator I bought was a cheapo, made in China affair, which adds to the aggravation, as if I pulled the tip back and put it back onto the blade, I would get different readings (guess I should just break down and buy a good Starrett dial indicator).

Argh! So I still don’t know if my saw is set up well or not. I need a better miter sled, that is readily apparent. Starting to wish I’d just bought a better saw in the first place, although I got the Bosch for only $310, still new in the package, which I thought was a pretty good deal. I may try to dream up something else that can fit into the miter slot more snugly to hold my dial indicator tonight.

I did pick up a 4×8x2 piece of pink foam as brtech suggested above so I can rip on the floor with a guide, but I got distracted the rest of last night putting up a new hanging fluorescent light out in the shop (garage) so I can see a little bit better out there. :)

Hopefully tonight can be a little more productive.
