Hey, I am just getting in to woodworking and am starting to get some tools. I wanted to get a decent saw that did not break the bank and based off of the reviews I read and watched the Ridgid 4512 seemed to fit the bill. I got the saw assembled and got my straight edge out to align the extension tables and quickly noticed that the cast iron table top is not flat. The table top seems to cup, the deepest part of the cup starts just to the right of the saw and extends over to just before the right miter slot. I used some feeler gauges and the deepest part is 0.32mm I took a few pics linked below.

This is a brand new saw just out of the box should I take it back or is this a non-issue? It seems like the cup is in one of the worst spots it could be in but I am unsure if or how much this will affect my work. I am pretty new to woodworking and I would like whatever saw I get to last me a while until I can improve enough to justify something that costs 2k. I would rather not have to disassemble this thing and lug it back to the store but I also do not want to fight with this thing to get good cuts every time I use it. Any feedback you guys can offer is appreciated.

Doesn’t surprise me. Had a late model craftsman that did the same. I just set it up like the bow didn’t exist.

Tough call… the cupped table is not good, but the ability to work upside down is quite the conversation starter.

You have a bigger problem, it’s assembled upside down.

So after making some test cuts I am not seeing any major issues so I think I will just keep it . If it ends up being an issue I can always put a few strips of tape over the low spots and put a veneer over top of that to make it all one big flat surface. Plus that is much easier than taking this thing apart and lugging it back to Home Depot.

Super annoying to disassemble and return, but I would definitely take it back!

I would return it as is and not bother with disassembly. Have them unload it at HD and mess with it.

He has a small shop… To save space he mounts larger pieces of equipment on the ceiling to double his square footage.

Ridgid quality strikes again. I’ll keep my pipe wrenches, sander, and vac., but I’m not buyin’ any more Ridgid stuff.
Just a personal rejection and opinion.

Here’s my prediction: You will live with it for a few years, but it will always bug you. Eventually as your woodworking gets better you will notice problems creeping into your work. You’ll have an, “aha moment” and realize the un-flat table is the culprit. It will be quickly sold. You’ll order a cabinet saw and you’ll think, why didn’t I get the cabinet saw to begin with?

IMO, the first step in checking TS flatness should always be to make some test cuts and see if it effects the cut accuracy. It generally takes a fairly large deviation to have an impact.
