Review on 🔧 2-Pack UHMW Precision Milled Bar 3/4" x 3/8" x 36" for Jigs, Fixtures, Miter Slots - Smooth & Durable Material for Easy Sliding. Perfect for Table Saws, Router Tables, Bandsaws. by Mike Flyers

I read a review saying these guides are too big for their table saw slots. After measuring my own table saw I realized that they would also be too big for my table saw (Shopsmith V) but I figured it would actually be good because I could cut them to the perfect size and I even had plans Make sure my rails have an edge so my sled doesn't rise. Well I don't seem to have the right tools for this. At 16 inches, they are a bit too wide and thick for me. The material is so hard that trying to scrape that amount causes my table saw and band saw blades and power tools to heat up and warp. Deformation is not that big of a problem, they arrived deformed, but you can give them the right shape for a while and they will adjust. I don't have a jointer or planer, but I believe these tools will have the same problems. (I confess I haven't tried hand tools or sanding). The lesson I learned here was to measure the grooves you are going to use them in and if they don't fit, don't buy them. DO NOT assume that you can fine-tune them. They are exactly the size they say and it was too big for me.
