In this video i show you how i made my precision miter gauge vith nonius for my homemade table saw. Free plans you can download here: 3D sketchup model:
Hope you will not repeat my mistakes and make your miter gauge more accurate.

First of all i want to say sorry for my english, i know it's fare from perfect, so please correct me if you see errors. Thank you
Transcript:
00:15 first of all i started sanding 1mm thick aluminum sheet with 150, 220 and 320 grit sandpaper
00:32 cleaning surface with acetone, i used a nail cleaning liquid, as for me it works good also
00:44 print flipped images on glossy photo paper (or other laser iron transfer paper, my was 150g/m) on laser printer with maximum toner settings. Also print it with 100% scale. Download images here:
01:20 started transfering images to the aluminum surface. For this purpose i used an iron in three dots mode (maximum). Few napkins helped to distribute precure evenly.
02:22 despite my best efforts, I have failed.
if you know why the image transfering partially, please leave your opinion in comments
02:38 my second try was not much better but good enough for me, themost important part transfered good
02:50 some dots that not transfered i protected from etching with nail lacquer
03:05 etching electrolyte i prepared with water (40g) and salt (about 10-15g)
03:10 for this purpose i use a 12v 3,5A car battery charger. Positive terminal connect with etching detail and negative use as etching tool.
03:55 continue etching until you will fill the relief with nail
04:23 cleaning toner with nail liquid or acetone
05:53 my second fail, i forgot that metal is much harder than aluminum and it can leave a scratches, don't do like that
06:35 gluing aluminum sheets to the plywood with super glue
09:15 when i drilled this 10mm hole the drill bit muve a little left and subsequently the center moved to, but thanks God it was not
affected the accuracy.
09:47 with this reaming mill i made a precision holle for 8mm bushing that is just a little longer than this angular scale board.
10:22 drilling 8mm holes in nonius part for 6mm screws. That holes are bigger just to give nonius a space for calibrating
10:38 yes, i for got about clamping slot 😜
15:58 yes, t-track are much better for this purpose, but i didn't have that so here is my solution. One day i will rebuild it for sure :)
16:10 making bolts for t-track from wide head furniture bolts.
18:00 i decided to glue up aluminum pipe in one of plywood pieces to fix it there securely.
18:25 assembling
19:11 angle calibrating
19:28 whe the piece you cut is perfectly square, set up the nonius part in position 0 degrees
19:44 making a quick set up holes. I made them for 0, 10, 22.5, 30 and 45 degrees
Hope this information was helpful
