The User Manual has a procedure for squaring up the blade to the miter slot. It also has a method for squaring up the fence to the blade.
I thought I’d take a square to the table to see just how far it is since I’ve never adjusted anything. I also noticed lately that when I do stuff on the saw the wood starts out against the fence but slowly creeps away. If I put pressure I am getting burns so the blade is probably out of alignment with the fence. But which is it? Is the blade out of alignment or the fence?
The miter slot comes to the rescue as the reference edge. Of course I didn’t follow the manual for how to realign yet, but I wanted to get a feel for how things line up. I took a square and here’s what I got:
#1 – The front edge of the saw is not a clean edge. It’s got multiple “layers” which make it hard to lay a square along it.
#2 – The back of the saw has a nice square edge without “layers”, but it’s not square to the miter slot. Makes me doubt the ability of the fence to actually work.
#3 – The front edge is square to the miter slot. It’s really square, which makes sense since that’s where the fence attaches. Well, sorta. The fence is on both sides… I think there’s more to the back of the fence.
#4 – Surprisingly, the blade is pretty square to the front of the saw.
#5 – Not surprisingly the fence is not and it’s further away at the back so that explains why wood creeps away from the fence as I push it through. It also explains why I use my miter saw to cut squares.
I realize I’m accumulating tolerances/inaccuracies by referencing to the front fence and not the miter slot but it seems like a table saw needs to be fence referenced for long cuts and to the miter slot for short cuts.
Now to follow the procedure for adjusting the fence…
