Not so fast!
Well I love the R4512 as well but it was a stormy honeymoon that was for sure.
First thing was the blade was not anywhere near being close to parallel with the miter slot, and trying to get it there using the manual method of loosening the trunnion bolts, tapping it then tightening back down said bolts only left me bleeding and using profanity a sailor would blush at hearing.
So I got this thing called the PAL Alignment system specifically for the Ridgid R4512. Strike one the new R4512 come with 10mm trunnion bolts not the 9/16th that come with that kits. Strike two, the "L" shaped aluminum brackets were to small too fit over the new trunnions. But I did get to use the 2 adjustment screws that the kits did come with to put into the new L bracket I made with extrusions I found at the hardwares store and the 10mm drill and the tap I had to get to drill and tap the holes for the adjustment screws.
After that I got it pretty near parallel. If anyone can get that blade true with the miter slot using the loosen tap and retighten those damn things than they are a better man than I. But with my homemade PALs system it was pretty easy to get it there.
NOW I have NOT had the issue YET with the blade going out of parallel when raising it and lowering it. That's a whole nother RANT
The fence is slightly not true flat, the heel of the fence on the front raises the stock slightly off the table as its feed in, to align the fence using the 4 allen bolts is a trial and error thing. More Error than trial.
BE WARNED! If you buy the PALs kit "even when you specify it for the RIDGID 4512" it will not fit or work! Same for the same one for the SEARS version of this same saw. I have e-mailed the inventor and seller about this and he says they have no intentions on retooling for these two saws and or WARNING on his webpage and or other advertising vehicles such as amazon about this huge FAIL! nice huh!
