Topic tags/keywords: question miter saw bosch runout tool dial indicator

I recently purchased a Bosch GCM12SD Dual bevel axial glide miter saw. There seems to be quite a bit of run out. I don’t have a dial indicator yet because I don’t know what I need which would be best to test the arbor and the blade. I want something that I can use to check other tools as the need arises. Does anyone have any recommendations for a versatile dial indicator (preferably digital), and attachments to test miter and table saws blade and arbor?

Harbor Freight sells one, not digital, but it works. It’s like 10-15 bucks. I’ve used it on my TS and drill press. As for attachments, they sell a magnetic base for it. I’ve just made a jig to hold it where I need it.

That’s definitely the right price. Does anyone know any techniques for measuring a miter saw?

Yeah, that is the trick to determine if the blade or the arbor is at fault. Test them both, perhaps it is just a bent blade.

The magnetic base won’t do you much good on an aluminum miter saw base (though I used to have an old 8 1/4” slider that did have a CI base).

The Harbor Freight magnetic base is quite heavy, you could add a wood clamp to it to gain stability, and yeah, the dial indicator is dead accurate and a bargain at the price.
