I am in the process of tuning up my grandfather's 50s Craftsman tablesaw. The model is 113-27521. I've read through the manual (http://www.manualslib.com/manual/497...113-27521.html) and I can't find any mention of 90 or 45 stops. As it's currently set up, it is possible for me to turn the hand wheel too far and go past 90. I have re-set the tilt angle indicator pointer thing, but I would rather rely on a mechanical stop than my ability to correctly eyeball a needle pointing at a line.
Looking at the guts, I'm pretty sure I've found the problem. The attached photo shows the tilt adjustment screw. It has a stop on it, but I can see that the lift bracket is able to slide up onto the stop instead of stopping when it reaches it. I don't think the problem is with the stop, I think the slot in the lift bracket is worn out so that it's big enough to slide over the stop. Since this part would be hard (impossible?) to find and the repair seems a little daunting, I came up with an alternative plan. I think there is room on the table saw base to just drill a hole from the outside and add my own stop bolt. I tried to illustrate that in the attached picture.

So my question...is this a bad idea? It seems simple enough, but I've been known to overlook simple things before. Has anyone done this kind of mod? Or see any problem with it?
