I'm trying to build a taper/straightedge jig for my table saw, but I've hit a snag with the miter slide I ordered from Amazon. It turns out the slide is 3/4 inch wide, whereas my miter slot measures only 11/16 inch. I've searched for alternatives but can't find any that aren't the same width. I could DIY a wooden slide, but I'm concerned about how it will hold up with the humidity where I live—it might fit well at some times and not at others. I'm also worried about making precise cuts as a beginner. I thought about using a plastic slide and shaving it to fit, but I'm afraid I wouldn't get an even shave and end up with a wobbly connection. Does anyone have suggestions for buying or making a miter slide that would fit well? Thanks!

What model of table saw do you have? It helps to know that to give better suggestions.
Consider buying a cheap cutting board from the dollar store to cut your own slide. They're usually made from UHMW, which is super slippery, easy to cut, and resistant to seasonal changes.
That sounds like a great idea! I’m a bit nervous about cutting it straight though; my attempts have been pretty uneven. Maybe I should invest in a push block to help with the cuts.
I’ve used two layers of 1/4” luan glued together for my slides. They stay dimensionally stable and don’t really change size with humidity.
That’s interesting! What thickness is your slide? I think mine is around 3/8 inch. How do you usually cut it to width? Do you take a bit off at a time for the perfect fit?

I’ve got a budget-friendly 10in Ryobi that I picked up from Facebook Marketplace. I might have to look into replacing it soon since it’s already malfunctioned on me.
