I built a cross-cut sled more than a few years ago, with an adjustable mitre bar. It sits unused against the wall in my shop becuase I cannot get a runner on it without it binding or being wiggly, and I hate wiggly. I've tried an Incra runner and a Kreg runner. I also bought 2 pieces of 3/4" x 3/8" cold rolled steel, but they don't run smoothly without a little binding (in the long run, I'd rather have a softer runner material than my table saw top). I can get the Incra and Kreg runners adjusted and running smooth through the table slot with no trouble, until I attach them to the jig. Then it's either bind city or wiggle-rama. For safety, I really want to build a sled that uses both table slots, but haven't even attempted yet - if I can't get one runner to run smooth, how do I do that with 2 runners.
I have a Jet table saw. It's been a some time since I checked, but with a dial gauge I believe the slots are quite parallel to each other. But back to the initial problem!
How do I attach runners to the cross-cut sled successfully? Thanks in advance for your ideas, as I may not get back to the forum for a couple weeks.
