I bought my R4511 in jan and am finally setting it up now. After aligning several cman 113 saws, doing the 90 degree alignment on this saw was AWEsomely easy. I set it up w/ a .003 toe out at the back. I debated doing this because most of the time I’ll be using a riving knife. But, I figured that wont be 100% of the time so better safe than sorry.

I’m using a guide I found on the rigid forums to calculate the shim thicknesses for aligning the blade at 45 degrees.

How much do you care about this alignment?
Do you guys w/ cabinet and hybrids also align at 45*?
Is it as critical as the 90 deg alignment for safety?

Is this worth chasing even to +-.003 that my guide suggests?

According to my readings the table at the front of the blade is .01” higher than at the back (an consequently about .03 over the front/back of the full table). BUT, I dont think the problem gets as bad as the 90deg alignment which gets worse by Error x Length of cut. The length of cut at 45 will only ever be 3-4” max.

I can’t speak to your specific situation with your saw; forgive me. But I have found that, in general, trying to get settings to be absolutely perfect leads to madness. You can fiddle and fiddle and fiddle and never get it quite right. Perfectionism is good-but only up to a point.

I don’t make enough bevel cuts to really mess much with the 45° setup….whatever I got from the 90° alignment has always sufficed.

when i disected the ridgid forum post by davewoodworks, i found it pretty easy to follow and applied it to both of my emerson electric built 10” contractor saws . i figure a little more accuracy @ set up will compensate for my lack of woodworking skill.
