I’m going to be purchasing a r4512 in a day or so, i was wondering about setting it up and squaring the fence and blade.

Can all this be done once its assembled? Or is it easier without some parts on?

I bought the craftsman 21833 and it is very similar. You will do this as part of the assembly process, the instructions will be articulated in the book. Otherwise there are some gentlemen who know rigid very well, PM Toolie, he is smart and knows a lot about rigid tools if you run into a problem. Knotscott is also very knowledgeable about table saws another smart one to ask.

I also have the Craftsman 21833. It is the same saw as the Ridgid 4512, made in the same factory, by the same workers from the same materials from the same design; otherwise, very similar except for the paint color.

The manual that came with mine was a photocopy of a photocopy of a photocopy and was pure crap before it lost some detail in the copy process. I understand the Ridgid does have a better manual. It was sorely needed.

I wish you better luck with your purchase than I had with mine. My saw has the amazing “Hula Arbor” feature. When you raise the blade the arbor twists out of alignment with the miter slot. Every movement up or down creates a different alignment condition and is not repeatable. Makes life interesting.

The only part that can be left off for the alignment process is the back cover. I would suggest, if the new manual does not already do this, that you leave all the cabinet panel screws almost loose (just slightly snug). That way you stand a better chance of getting the screws into the back cover when the time comes to button it all up. While the saw is upside down, and before you put the bottom on, it’s a good idea to determine the location of the bolts you use for alignment and figure out how to get the wrench in there. It will help you when alignment time comes and the saw is upright and the bottom is covered..

By the way, blade to fence alignment is not the problem you need to be worried about. That is done from the top and on the fence itself. The blade to miter slot is the bear and comes first. Just pray that it holds constant and does not do the twisty thing like many of them do.

Thanks crank, appreciate the help. How long ago did you buy your saw? I thought that problem was rectified.

I bought my saw in the spring of 2009, before Ridgid came out with the R4512 that fall.

I don’t think the problem has been solved. Ridgid, or maybe the Chinese manufacturer, have determined the number of complaints they get are acceptable, I suppose. Someone on LumberJocks, just a couple months ago was explaining how they bought two Ridgid R4512s, one right after the other, that had the problem. They gave up and bought something else.

If you get a good one, it’s a sweet running saw at a really fantastic price. I’m not saying otherwise. Just be sure to check for the problem. I haven’t heard of one developing the problem due to wear or anything. It’s either good or bad right from the start. Some kind of manufacturing defect.

I understand some have said if you raise it it goes out of alignment, but lowering slightly fixes it. If thats the case i can deal with it. I just know i cant spend $1000+ right now and not to mention 110v is my only option.

On my saw, raising the blade will twist the alignment out in one direction..back of the blade moves away from the miter slot.
Lowering the blade will move it back in the other direction, but not necessarily back to the aligned position.

Now, it might be that the saws that don’t have the problem will deflect in one direction and then return to the correct position when the pressure is reversed. I suppose that is possible because the guide rods in there are very light weight and the lifting mechanism is not centered. But, the saws like mine, with the alignment problem, do not return to the aligned position. Something in the system is actually shifting position, not just deflecting or bending. Since I don’t have a saw that returns to correct alignment, I can’t really say for sure how the good saws behave.

I had the same problem with a 4512 I bought this year. It wasn’t to bad when I first got the saw (I thought I could live with it) but it definitely got worse with time – resulting in a pretty bad kickback after a couple months, at which time I decided to return it.
I found that the blade to table alignment problem goes beyond just parallelism, but it also goes out in perpendicularism (is that a word? I guess it is now). The blade does kind of reset to “parallel” to the slots if you unload the screw that raises and lowers, but if you hit it with a square, it doesn’t necessarily go back to square to the table every time. It’s really a mess – and ALL the saws at HD were the same (the manager and I look at the entire stock and he RTV’d all of them)
And by the way, if you need to angle the blade, all bets are off.
But boy that saw is quiet and smooth!

I tried three r4512’s back in the spring of this year and found they still had the problem. Since Ridgid won’t acknowledge the problem exists, I doubt they’ll ever fix it with this model.

Thanks for the replies gents. I ended up picking it up. Hopefully i got lucky, but I’m not holding my breath, worst case is i have to take it back. We’ll see.

Has anyone actually tried fixing this issue themselves? Seems like for such a great saw it would be worth the time.

so i took the motor housing out of the box, raised it up and down and noticed the back moving in and out. Back to home depot it goes, and i’ll be looking for another saw. It’s a shame cause its a nice looking saw and there were many nice things said.

Have your say...
