Good Evening All,

I recently purchased a Ridgid R4512. I liked the features and since mine was built in may of this year, i thought most of the issues from the earlier built machines had been resolved, such as blade alignment as the blade moves up and down. I have another issue though. No matter how hard i try i cannot get the blade parallel to the T-slots. The best i can do is 1.32-1/16 inch front to back which is far from acceptable. I have even flipped the saw upside down to adjust the trunnions, it is like i am hitting the max adjustability and it is not enough. Has anyone else had this issue? If i can’t resolve it i will return the saw. but before going through that trouble, i thought i would ask if anyone else had a solution.

Drill out the trunnions holes. 3/32 more or less by what you’re dialing in so far.

Folks just won’t listen.
You got what you paid for, the cheapest, most poorly made table saw wanna be on the market.
You have my regrets.

I would return the saw. I don’t feel like you should have to remachine holes to make the saw work as it should.

Thanks for the responses all. I realize that i purchased on the lower end of saws but it is what i can afford right now, i searched months on CL to find a used cabinet saw but found nothing, what little i did find the owners were asking within a few hundred dollars of new. I would prefer to not start hacking on the saw while i still have the option to return in. Lifesaver2000, thanks for the thread link. The only thing i see that i did not try was backing off the set screws in the table. i did however tilt the blade a few degrees when adjusting so neither screw was making contact with anything, because of this i do not believe it is the issue. I think i will end up returning the saw, though i am torn which way to go. Get another R4512 and hope for the best, i really did like the saw otherwise. However i sure dont want the same issue all over again. I could go to the blue store and get the delta 36-725.. but i am not convinced this is a better saw, it costs more and i have not heard good things about the new delta’s customer service. Last option is scrounge up another $200 and order the Grizzly GO771, which has cabinet mounted trunnions and as a result i believe does not suffer the same issues as The R4512 and GO715P. Any other opinions?

I own the R4512, for the same reasons you do, Alex. It was about all I was willing to spend. And I didn’t want a contractor saw, the Grizz was more money for another Asian rim saw, etc….

But mine, through about the last year and a half, only had one problem – the C clip on the end of the worm gear that raises and lowers the blade came off, causing the gear to back out and jam into it’s mate mounted on the blade assembly. Instead of taking it all back, which is what they wanted, I decided to unjam it myself and put on a more reliable C clip, which cost me about two hours of my time and 80 cents for the C clip.

So much has been said about the trunnions on this saw, it gets hard to read it all. It is obvious that some kind of QC issue was not addressed in China and a fairly high percentage of them came out with the holes in the wrong places. My saw, the blade does move off parallel during the raise/lower process, but has always come back within .002-.003” when I am finished moving it. So I guess I got a good one.

It really comes down to two paths:
1. Do what The Fridge says, and enlarge the holes just enough to get you home. I personally would start with a round file, but using the side of a running drill bit would also work.
2. Pack up the whole thing as Joey suggests, take it all back, and hope you get one that does not have misaligned trunnion holes, or if they will give you all your money back, start over with some other brand and possibly spend more money.

That was my decision when my worm gear jammed into the half moon gear on the blade assembly. I decided honking all that iron back was harder than me unjamming it, checking everything for straightness, and putting on a new C clip, which has held beautifully. It is your decision.

And we all run into bad products from time to time. We make decisions on buying more based on our own personal experiences. I won’t ever buy another Craftsman product – others will never buy another Rigid product, and on and on.

If the 4512 is the most expensive saw you can afford, than you’ll have little choice but to exchange it for another 4512. Of course, there is a 50/50 chance you’ll end up with another turd.

That said, If the ONLY problem with the saw is the blade/miter alignment, then I’d take a drill/file to it and fix the issue myself.

Also, when you adjust the trunnions to align the blade to the miter….don’t completely loosen the trunion bolts. Leave them 85% tight (very snug). Adjust the trunnion with a dowel and a hammer. Re-tighten the bolts in a cross pattern, a little bit at a time.
I have a finicky craftsman that is hard to adjust. Its not anything close to 1/16” bad though. So enlarging the holes is probably your only play.

I am torn between exchanging it and trying again to see if i can get a good one, or paying a little more for the G0771. The grizzly appears to be a lot more saw with cast iron wings, full cabinet, slightly more powerful motor. Are these decently well reguarded and worth the 200.00 step up from the ridgid?

WAY better saw than the 4512. If you can swing the extra $200, I’d return the 4512 today and buy the Griz.

I wish I had a quarter for every time I’ve heard that “I Looked, I found nothing, I bought new….” line. I’d probably have enough to buy a new PM2000 if I did :)

The formula is pretty simple – patience and persistence. Some people will stumble across that killer deal right off the bat, and some will search for years before they stumble across it. Keep in mind, those great deals don’t sit out there very long – so what you usually wind up looking at are the ones that have been out there for a while (or will be!) due to price/condition/location/whatever… But if you are persistent, that deal will come along eventually. In the mean time, a nice used C-man or Delta contractor saw can get you by until the real deal comes along – at which time, you can sell it to recover the money you paid for it. There is no way I would pay money for any of the current ‘new’ offerings when you can get much more of a machine for a fraction of the cost.

Cheers,
Brad

I’d definitely vote for returning and buying the Grizzly if you can swing it. If not, I would not recommend returning it for another rigid unless there is something else wrong with the saw. It only takes a few minutes to file the holes out a bit and is much less work than loading it up and taking it back to the store. And, there’s always the possibility that the next one will have a different problem that isn’t so easily fixed. Filing the holes out won’t void your warranty. So, if you’re gonna stick with the Rigid, I’d say take a stab at fixing the one you have before exchanging it.

Definitely return it. The Delta 36-725 equivalent has a better track record, and a better fence. The G0771 is a nice option too if you can swing the extra money.

I too have a 4512 and must have been either:
1) really lucky as no alignment issues (yet)
2) really lucky as no jamming (yet)

Like the OP, I bought because this is what I could afford AND it was used so I got a GREAT deal. Is the saw perfect? Nope. Would a top-of-the-line Powermatic or Unisaw be perfect? Nope. The point being that every tool will have some issue(s). We just have to learn them, work around them.

So, Alexl, if you like the saw and just need to file/drill out the holes to make the saw perfect for your use, I’d say go for it. If you don’t feel comfortable doing that, then haul it back, do without a saw while you save pennies to get the current “good” saw that the internet suggests.

Thanks guys, i tried the whole obround thing with a file on the trunnions. it did get better… however now the step-downs on the trunnions are butting against the bosses on the table so no more movement is possible. I could file more clearance on the step-down but i risk messing up the machined surface and causing worse problems. Because of this, the saw is going back. i have family in missouri that i will visit over thanksgiving so i could possibly swing by grizzly’s retail outlet and save on shipping… unfortunately i am in the middle of a project and need a tablesaw sooner than that.

Why do people keep buying this saw? It is diseased with problems. And for goodness sake, stop recommending them to people.
