I recently purchased a used Craftsman table saw which came with the OEM miter gauge. Like most OEM miter gauges, the miter bar was loose in the miter slot making the gauge some what less than accurate. I looked online and the starting price for a “precision” miter gauge is $65 outside of my budget right now.

I then had an idea. I have some clear plastic shipping tape, you know the thick indestructible type. P stuck a layer of it on one side of the miter bar, and trimmed of the excess. My miter gauge now has about 0.002” of play! And after building a stand for our automatic kitty litter box, the tape is still in excellent condition.

I am going to try sticking a layer of thinner cellophane tape (Scotch tape) on the other side of the bar to see if I can eliminate even more play.

I just bought an Incra miter (it’s as good as is claimed) and now I have five miters sitting gathering sawdust. I was thinking of using them for jigs in the future. I’m thinking of having the bars drilled like the incra, then use the same nylon discs to get rid of the play. I may do it myself if I can find the right bit! Your idea sounds like a good one though!

I just used this on my bosch 4100 stock miter gauge and it worked great. Easy to apply and trim.
My main use miter gauge is the incra V27. It’s great.

I use a center punch and hammer to tighten the slop out of mine. Just want to make a few ‘dimples on both sides along the bar. If you get it too tight, a little sanding will tweak it to perfect.

The aluminum tape used to seal ducts might last longer and be a more smoothly sliding surface.

My first thought was to drill and thread the miter bar for 10-32 nylon screws with the heads cut off. On second thought way too much work. Also the tape is a continuous solution vs a point solution. I’m glad others are using this same idea!

No OEM miter gauge is accurate, but most can be tweaked with little effort so it will be as accurate as the after market ones. The accuracy of any miter guage is dependent on the fit between the miter slot and the bar. There are several ways to fix this. One is to cut a slot in the bar, front and rear and drill and tap a hole for a set screw. Adjusting the screw, widens or shortens the width of the bar. This works as long as the slot in the table is straight and true as to width. Cheap table saws may not have slots uniform enough for this to work. Another method is to drill and tap holes into the edge of the bar and threading in a nylon screw. Most of the after market gauges employ one of these tricks. Off course tape works. It just might not last too long, but at least, it’s a cheap fix that can be repeated as needed at no cost.

Ron, aluminum tape will last a very long time.
Masking/packing tape, not so much.
