Well, I took a chance and bought an R4512 today. Bought it home and unboxed it. It tested it before fully assembling. It has the problem where if the blade shifts t to one side by about 1/16” when I change the height of the blade. What are the chances of finding a good one? After all the driving to get it and the trouble of getting it in and out of my van…. I just would hate to return it for another one with the same problem. Has anyone really diagnosed the actual problem? If you get a good one, could it go bad over time?

So frustrating… but I do have to say thanks for the other LJ’s who warned me to test it before completely building it.

When I go back to HD tonight, I’m going to see if they are willing to open up and test a new one. It just worries me that if 10-50% of the machines have the problem, that it must be a design flaw and could happen later down the road. Glad to hear yours is working well. How long have you had it.

Look at the serial numbers (or manufacture dates) of the one you are returning as compared to any others they have in stock. They may even be able to TELL you when they ordered and received them. I got stung by this myself, and unfortunately for me there was no replacement available that did not ALSO have the problem. My current understanding is that if you get a good one… it stays good. The problem is apparently a manufacturing flaw, not one that shows up over time. There are several people that have the R4512 and it’s fine. If it was going to DEVELOP the issue, I think it would have shown up by now.

Oh…. and my local HD was VERY understanding with this. The manager bent over backwards, even offering to send a couple guys and a truck to my house to pick up the defective one. They don’t have to do that. I’ve found HD to be pretty decent to deal with when it comes to returns.

Ask for a manager and explain that you’d like to exchange due to defect, but that there is a known issue with these saws that you believe was fixed in newer stock. They were perfectly willing to help me partially unbox a replacement and check it.

I think you’ll be fine. Hopefully you’ll get one that is free of the issue. I really liked the saw. But between having no stock without the defect AND finding out there’s no service center closer than about 300 miles (HD doesn’t service the big tools)... I just couldn’t go forward. Ended up with a Steel City 35990G. Also a nice saw (just used it this morning :) )

Worst case scenario, you’ll get your money back from Home Depot. That’s what ended up happening with me. Mine had that problem with the blade shifting as well as with being unable to align the blade with the miter slot with any repeatability.

I don’t think this was anything that was ever corrected in a different production run though. I had a model that was manufactured in September 2012, and I saw reviewers say that their saw had no problems that posted before my saw was manufactured. You can the manufacturing date on the label on the outside of the carton. If I remember correctly, there’s a code that says EMXXYY where XX is the year and YY is the week # (1-52). Could be the other way around too, my memory is a little fuzzy.

If you can manage to find a good R4512, you’ll be getting a decent saw for the price, but if not, I agree with Charlie; if you can swing the extra money, the Steel City is a better saw.

Or there’s always Craigslist…

I have one of the duds. Mine is the 21833 Craftsman.
I really don’t understand how these saws get so many good reviews.
Even if mine did not have the problem I would still be very disappointed with it.
I have pointed out on here many times they are designed on the bleeding edge of failure.
I would be amazed if this saw lasts more than a few years of light use.

I was thinking about how I’ll work with HD to test the saw before I buy it. Then started thinking “they ought to look at all their inventory so they don’t sell anyone else a defective saw.” My next thought was, ‘dump thought’ we all know that will never happen. It really is a shame and says a lot about both Home Depot and Ridgid, when they have a product with a known defect and not only do they not fix it but they don’t even test it before boxing them up and selling them.

craftsman70…......i saw a comment on a thread somewhere over the last couple of days from a 4512 owner with the alignment issue. he noted that, once properly aligned at a “low” height, elevating the blade beyond the needed height and then lowering it to the height needed for a cutting operation, returned the blade to proper alignment. sort of like backing into the cut height as opposed to raising the blade to the needed cut height. just passing on some hopefully helpful info.

Thanks Toolie, I see how that could work. That is probably the best path for people who have owned theirs past the 90-day return window. I do already have an older Craftsman (~1999) I can fall back to, so if I can’t get a r4512 that works correctly, I am just going to stick with my old one.

Toolie, I don’t think that will work. I have a good R4512 but I have seen a bad one. All you need to do is touch that height adjustment knob (literally) to kick it out. It’s less noticeable to the eye at lower heights, but it’s there.

Can someone point me to a thread that describes the problem in full detail and how to diagnose it? Would be greatly appreciated.

Craftsman....If you want a Ridgid, the LJ member (Shelly_B) who won the Baileigh Contest has a Ridgid 3650 for sale that includes sleds and inserts. You might luck out and she might be a short drive from you

Craftsman, sorry about the bad luck with the saw. As far as Home Depot checking their saws, this is a quality control issue at the factory.

These saws come boxed up and unopened . Its not practical to expect Home Depot to inspect every piece of machinery that comes into their stores. It just isn’t going to happen. And when customers buy new, they expect to
get a product in an unopened box. Otherwise, it qualifies as a display model.

But Home Depot is obligated to take care of the customer and honor the warranty. I’m sure they will work with you, but its really a manufactor quality control problem, not HD.

Matt, it’s really easy. You can do it in the home depot parking lot

1. Install the blade. You don’t even need to assemble the saw

2. Raise the blade about 2.5 to 3”

3. put something flat and straight (a steel rule, long combination square, etc) flush against the blade right behind the teeth so it barely makes contact. Make sure the blade is pretty square and the angle is at 0 degrees.

4. clamp the straight edge down

5. Attempt to raise or lower the blade. You don’t even need to crank away at it. As soon as you have tension on that screw, the blade will either jump into or jump away from the straight edge if the saw is defective. It’s very noticeable to the naked eye – we are talking like 1/16 of an inch; not thousands of an inch.

Toolie, I don’t think that will work.

as i think i indicated, i’m not advocating the process as a solution. merely passing along info ( wish i could remember where i saw the actual thread!) in an attempt to be helpful. i don’t own a 4512.
