People often complain about their table saw miter gauge having too much play.
I find it annoying myself. Especially when you want consistent, accurate cuts
when making box joints. I saw that Delta makes a miter gauge with adjustable
screws to eliminate that problem. So I basically imitated their concept on
my own miter gauge. My only concern was that I might ruin my fairly new gauge
in the process.
I chose brass screws over steel, because brass glides smoother and won't be causing further wear in the miter slot. It is somewhat difficult to find brass setscrews...so that means you have to cut the heads off each screw and then cut a slot using a hacksaw. Not very difficult.
Use 10-32 brass machine screws. Tools: Drill press, vise, center punch, #21 drill bit, tap & die set, cutting oil, hacksaw.
With normal table saw usage, the screws will wear very slowly.
You might have to tweak an adjustment once in two months....and usually
less than 1/4 of a turn.
A small amount of Locktite on the screws may help to keep them from getting loose.
