I was going to spring for a commercial ts alignment tool but had a few 8020 leftover brackets. I cut a perfect miter bar out of QSWO and assembled a very solid miter slot alignment tool. I just had to drill one hole to attach the gage and 2 holes in the wood miter bar. It works beautifully and just wanted to share in case you want to save a few bucks and make your own. It took 10minutes to drill the 3 holes, tap one hole and screw together. I don't remember the part numbers but if anyone is interested, I try and can dig it up from my old files.
