Bought a used ridgid 3650 table saw a little bit ago, got reading about problems in the beginning about not being able to use dado blades because of a certain problem. I've never used dado blades or had a table saw that could use them. Took my blade off for the first time to change it and was looking at the shaft it goes on. Not sure but I'm assuming its the one that won't use dado blades. There's a notch on the bolt which I assume will mess up the height of a dado stack. Attached a pic to get your alls opinions, if that's the case is there any way of getting a replacement for it? Would really like to be able to use a dado blade down the road.

Looks like you might have one of the miscut arbors. You can use a spacer like a thick blade stabilizer or very flat washer to take up the gap, you can fill the gap with jbweld, or you can replace the arbor.

That misfit arbor was a problem in some 3650 s a while back. I think they were replaced for original owners by ridgid.

Could you use a blade stabilizer to space the dado forward of that spot a bit? That would throw off your fence measurement and mean the max width of the dado you can use is less but I would think that would help.

If you can get a corrected part it might be worth doing but I don't know how hard the part is to get, how much it cots or how hard it is to install.

Good luck.

I don't see why you couldn't still use it with a dado stack.. as long as you are not concerned about the middle portion being perfectly flat (which usually isn't a problem for most situations).

Cheers,

You might be able to wrap copper wire in the slot to flatten it out. If one chipper or blade drops down into the clot the set will be unbalanced and being wobbling, how much I don't know but probably enough to be upsetting and eventually mess with bearings

Figured I'd post this just in case anyone else runs into the problem and searches the web and finds this thread. Finally got around to calling ridgid today and told them about it and getting it fixed. Forgot how they worded it, but basically since there was a recall basically for this problem, it's on a list so even though the saw is old and I didn't buy it new or anything, it's still covered under warranty to get it fixed.

I have the same saw, purchased 2nd hand years after it was first sold and it had the arbor problem.

I called Ridgid and asked them to repair it, and they did. At no charge to me.

Give them a call and let them make it right. If they balk, mention how unsafe it is and such.

Great idea. Mention the word "safety" to almost any manufacturer and they will usually fall all over themselves making it right for fear of liability and unfavorable publicity.

So I took my saw to the repair place today, get a call from them saying they called ridgid to get whatever code/number they needed to get the go ahead to get the parts to fix it. Well the person they talked to said they've never heard of such problem or anything like that dealing with the 3650. So I called them and got the same response, said they've never heard of any issue with that saw and basically I was SOL. Even though the person I talked to yesterday said it was cleared to get fixed and that the problem is posted to a bulletin for that saw, so even though it's older and I bought it used it should be fixed. I also had an email from them from a couple months ago asking about the problem, they said it wold be fixed. The ….. woman said well my supervisor and no one has heard of that problem. I wanted to yell at her and use some choice words but didn't, but all you have to do is search the internet and you can find out about the problem, guess they think I'm too stupid to know that. Sent another email and made a rather lengthy post on their facebook page about it. So freaking pissed, my table saw is stuck at a shop all weekend with no part coming and not sure when/if it'll happen. Meant to mention in my rant on their page how I'd hate to stack some dado blades on there and be in an accident especially after trying to get the problem fixed.
