Topic tags/keywords: question

I have the opportunity to receive a Ridgid R4511 carcass (no motor, switch, or fence). I’ve been reading lumberjocks for a few months now and am very much a woodworking noob compared to the majority of you, so I’m hoping some of you might be able to help point me in the right direction.

I have done some research regarding replacing the motor, but have not had much success, other than finding one site that had a direct/OEM replacement that retails for something like $680. Yikes! In my search I saw one guy on here who retrofitted a 3HP motor, but there was surprisingly little specific information (brand, model #, etc.). One issue appears to be a unique, non-standard bolt pattern, but I may be mistaken on that. Does anyone know where to obtain either a 1.5HP direct replacement for a much better price, or provide some input regarding a particular 3HP unit that I could use instead of the OEM unit? Also, if the bolt pattern for the mount is indeed unique to the OEM motor, would it not be possible to fabricate a new motor mount (I have access to the necessary equipment to fabricate one, if need be)?

Regarding the switch, I realize I’ll likely need to match the switch to the motor, but if I end up going with an OEM or similar 1.5HP motor, is it safe to say that I could get an appropriate “aftermarket” (i.e., non-Ridgid brand) for significantly cheaper than the OEM replacement?

Thanks in advance for help/insight you can provide.

how much did you paid for this Ridgid R4511
With all the missing parts, it is not worth your time.

Sell it and get the RIDGID R4512

The R4511 has the big yoke style cabinet mounted trunnions, so it has some mechanical advantages over the R4512. The fence was the weak link, so if you picked this saw up cheap, it could be worth pursing.

Those trunnions were made for a 1.5 to 2hp motor, and that’s what I’d suggest you look into. I think it might have a standard NEMA 56 frame (not sure)...if so, it shouldn’t be hard to find a suitable off the shelf motor for it that won’t break the bank. That saw is made by Steel City/Orion and has the same guts as the Craftsman 22116 and the Steel City 35925, 35930, and I think the 35950. You might even find that a motor from a Craftsman 22104, 22114, 22124, older Steel City 35605, or even a Delta 35-715 would fit. You could always contact Steel City to find out what you need and see what they charge for an original, but you should also be able to find a good motor from Baldor, Leeson, Marathon, Dayton, WEG, GE, Reliance, Grizzly, and others…choosing the proper mount, duty ratings, and specs are just as important, if not more important as the brand. It’s hard for me to imagine that you can’t find one for < $350 new. A decent used motor could the ticket if you can find one….$75-$125. It’s a left tilt saw so be sure to get the correct rotation or reversible rotation.

The Delta T2 is a great deal at < $155 shipped from Tools-plus.com.

I’m getting the R4511 for free. I understand that it would be easier to just buy a new saw, but if I were to go that route, the 4512 probably would not be very high on my list. From the reviews and such I’ve read, the 4511 appears to get significantly more praise than the 4512 (all granite vs. cast center/stamped wings, cabinet vs. table mounted trunnions). My thinking is that for maybe $500-$600 (hopefully less) “investment” and a little effort, I could have a unit that is equal in quality to a new $700-$1,000 saw. Is that unrealistic?

knottscott… One of the threads I read in which someone asked about swapping the stock motor for a 3HP said that Steel City made a saw identical to the R4511, but that the Steel City one included the 3HP motor. From what I read, all internals aside from the motor were the same between the Steel City and R4511 (” there is no difference in any of the part numbers but the motor”). If that is true, would it not stand to reason that the R4511 could safely handle an appropriate 3HP motor?

There’s not much too it, but here’s the thread: https://www.ridgidforum.com/forum/t32782/

not sure where you’re at but you might check to see if there is a motor shop in your area. When I was in SoCal there was a guy who re-did the windings for motors and alternators (he was the guy who was actually rebuilding cores for most of the local auto parts places) and I could get great rebuilt motors from him.

There are definitely benefits from having a 3hp motor, assuming you’ve got 220v to power it, and assuming the saw’s inerds are made to handle it. A few years back I had read that Steel City made a 3hp version of their earlier hybrids (not the newer ones like the R4511) that had beefed up parts to accept the bigger motor…the story went on to say that according to someone “in the know” at Steel City, the 1.75hp Steel City hybrid had the same parts in it as the 3hp version. I don’t know if that’s true of these particular models. There can also be a difference between “very similar” and “identical”, and it can be hard to know what the difference is. It sounds like you’re doing your homework though, and these things are fairly stout.

Keep us posted please!

I may be ‘looking a gift horse in the mouth’ here. Is the rest of the saw ok? Do you know why it was stripped? Seems funny that the motor and fence would be taken off a running saw. That said, if the only thing wrong with the saw is the missing motor, switch and fence, go for it. Switches and fences are often upgraded from stock anyway. -Jack

Greg, thanks for that tip. I hadn’t even thought of that. I’m in Alabama, and there’s actually a couple places in Birmingham that rebuild. I’ll be getting in touch with them.

knotscott, I definitely need to research it a bit more, and probably contact the few who mentioned the two being identical, to try to verify that information before going that route. I am very mindful of the gap between similar and identical.

Jeff, I’m in no hurry. I’ve been looking at saws for several months. I may be able to find a nice used saw for less money. The problem is, I’ve been scouring craigslist and the like for several months now, and literally nothing worthwhile at a reasonable price has come along. Or, what few decent deals pop up are either more than 3 hours away (negating much of the savings) or sell very quickly. I was set to drive to Nashville this weekend to pay way too much for another R4511 ($450), but it sold within three days of the ad being posted. 90% of the other table saws I’ve seen are 20+ year-old Craftsmans that people want $300+ for. And half those sellers don’t even know what the model number is for the saw they’re selling. It’s quite frustrating. As far as buying a new one, I would be looking to spend roughly $900 to get what I want. Considering I can likely put maybe $500-$600 (and a little sweat) into this R4511 carcass and have an equal quality or better TS, I am not too motivated to jump on a new unit.

Jack, the owner supposedly used those items (motor, switch, fence) on a different saw. Other than the missing items, it’s in perfect shape. And yeah, chances are I would most likely be replacing the fence on a new saw anyway, so I might as well start with a blank slate, so to speak.

Here’s a motor rebuild and replacement service in Leeds, AL.
I have used them for industrial service.

But, if you change your mind and decide not to fix it, I’d be glad to take it off you hands. I would take the motor and fence off my 2 year old Craftsman 21833 (same as the Ridgid 4512) and put it into that saw.
