Hi everyone,

I have had my R4512 for about 18 months and have not really used it much because all the fun life stuff. When I first got it I didn’t notice much blade shift, but I obviously wasn’t paying attention. I have finally measured my shift and it’s about 0.018” before tightening it. Once tightened it goes to about 0.020-0.024”, and once you take tension off it drops back to zero +/-0.002”. I have contacted Ridgid and they did say it needs replaced, but I am worried they will claim nothing is wrong once they have it. I hav sent back asking if they can send me the trunnion so I can replace it, since this will be cheaper for them. I even said I would understand that I would be expected to pay if I had to send it in if I could not put it back together. I am just waiting a reply.

I have seen this thread: http://lumberjocks.com/replies/on/2873123
It outlines the procedure pretty well. My question is has anyone been successful with either replacing the trunnion themselves, or has Ridgid actually done it and your shift gone away.

Sadly, I should have been paying more attention when I first bought it, but my son was born 3 days later and then life just happened. Thanks for any help and I appreciate ahead of time.

Just do not raise the blade all the way up beyond of what the saw was designed for and you are OK.
Or if you want turn your hybrid into monster Oliver you can make something like this guy

Thanks a lot for that video. That seems like it takes as much of the twisting out as you can hope for on this series of saws. Appreciate the input.

Well Ridgid has emailed me back and they are saying I have to send it in for repair, and they will not send me a replacement trunnion. I guess I will have to decide on if I want to send it in for repair and gamble with if they will fix it, and be out a saw for several months, or attempt the repair in the video posted and see if that will add some rigidity… I may try to call and see if I can get anything to work. we shall see.

Find a local authorized repair shop and drop it off. That is what I did with my Rigid 3650 and it took only a two weeks or so. It looks like there is one or two in your area, though not a short trip. Here is a link to their search tool: https://www.ridgid.com/us/en/service-centers-repair

Good luck!

On the second thought it looks like you have an imaginable problem. Start using it and you’ll discover there is nothing wrong with it.

For what it’s worth, I convinced the Rigid tech support to send me a replacement trunnion. They sent me the same version of the trunnion, with out the roman numeral II. This was only few months ago.

I added some custom made “Saw Pals” out of 1/4” angle iron on all 4 corners. I squared the table to the blade at about 1 1/2” blade height. It was dead on in the middle and out about +.002 at 1/4” height and -.002 at 3”. I had zero issues after that and all of my cuts were smooth as you could ask for. I used a 50 tooth Diablo combo blade and could barely feel saw marks, seeing them was even tougher, crosscutting and ripping at any height.

Don’t forget to get some shim stock for between the trunnion mounts that the table to square it up @ 45 degrees. Once I had everything set, nothing moved and it stayed square for more than a year of at least 3 times a week average usage. It really is a great saw for the price.

No but here’s a photo of one of my prototype pals made out of 1/8” angle iron. It flexed so I made a new set out of 1/4”. It’s sitting on top of some ripped cherry off cuts.

So let me understand the problem. The blade deviates 0.018” when tightened from what ? From untightened position ? Why would you measure it this way at all ? Just calibrate it when tightened and you have a perfect saw.

Have your say...
