So I got my new Osborne EB-3. Wow. What a nice piece of engineering. It’s much heavier than I expected.

So of COURSE I had to go out to the shop and set it up. Interestingly, having a really good miter gauge, adjusted properly in my miter slot, pointed out to me that my blade-to-slot alignment was off. So I got out the dial indicator. It was off by .010.

That seemed excessive. Now I have the Steel City 35990G. The miter slots are split. Part in the main table and part in the wing. Hmmmmm….. conundrum….. How can I adjust my alignment without removing the wings, because if I remove the wings I don’t have a miter slot to use to check the alignment?

So I left the wings on. The front and back fence rails are bolted to the main table and the wings. Would this work? Short answer, yes! I loosened the 4 bolts in each wing (the wings secure to the saw frame, not the main table), and the 4 securing the main table, leaving the front right bolt pretty snug as a pivot. Applied some pressure in the direction I wanted to move, tap, tap, tap, with a deadblow on the appropriate spot and BAM! (as Chef Emeril would say) I had the alignment to half a thousandth. Go around and slowly tighten the main table bolts back up. Then each wing’s 4 bolts. Recheck alignment. .0015. So I’m a thousandth and a half off. OK I can live with that. Roll the saw back into its position, recheck alignment and it’s .001. I’m going to guess that this falls within the variance of the dial indicator and my ability to secure it etc.

Recheck flatness of the top. The left wing was hanging a bit too low at it’s outboard edge and was up just a hair at the seam. This is a relatively easy adjustment and took just a couple minutes. Sow now I’m aligned and flat because of the EB-3. :) Oh… and while I have the covers off I may as well vacuum the insides.

Recheck the EB-3. Needed a little tweak to the guide bar width adjustment.

So getting this one new toy, lead me to make improvements and adjustments to my table saw that I’m pretty sure will be noticeable. I still haven’t worked on the kitchen yet today, but hey… my TABLE SAW is diggin’ all the attention. :)

I had the opposite happen, I tuned up my TS and realized just how crappy my miter gauge was. I too invested in the EB-3 and have never looked back. My only complaint with it (and it is a small complaint) is the fact that attaching an auxillary fence can be a little tricky. Enjoy!
