Older Delta Contractor saw
I just acquired a model 34-444 type 2 (I think) contractor saw off craigslist. It runs great and is in good shape, but I have two issues. One, there are no stops for 45 and 90, no holes in the table top for them. Two, the gear that tilts the blade has some play, and there doesn't seem to be an adjustable eccentric like Dewalt told me to look for. Apparently some models had this. It rattles a little when it's running, and I'm concerned about accuracy (the reason I bought the saw in the first place).
Does anybody have experience/ideas that might help either of these?
