I was cruising the surplus isles at Princess Auto the other day when I noticed they’re selling Craftsman 22575 Digital Readouts (DRO) for about $15. I wasn’t sure if I could adapt the DRO to a non craftsman table saw, but I was willing to give it a gamble.
The trick to adapting this is to make sure your mounting point only moves in one axis.
+- half a degree isnt bad! That said this is a portable table saw and the angle finder needs to be zero’d every time the saw is moved.
If you want an digital angle readout and you dont want to modify your saw. You can always use something like this portable digital angle finder gauge.
