  • Possible Handwheel Fix/Repair

    New to the forum, been lurking for a while!
    I recently picked up a BT3000 for $60 and it needs some work but I don't mind. When I got the saw the blade wouldn't raise up and down and the gears would start to move and stop and the handle would just spin. I pulled the handwheel off and the hole in the handle with 2 flats to mate with the shaft that drives the gears to raise and lower the blade looked pretty much like a round hole with no flats in it. I could tell that the support ribs around the hole were more oval looking than round. The plastic had not been chewed away, just deformed. I suspect that the raise and lowering mechanism had gotten dirty and the previous owner tried to force the handwheel and left it sitting for a very long period of time with the flats of the handwheel aligned with the round part of the shaft and the handwheel had sort of permanently taken that round shape. The shims for the raising and lowering mechanism are in place as they should be and the aluminum threads are not stripped out (yeah for me!) so I'm pretty sure it is just dirty and not wanting to move as it should. For now I wanted to see if I could work on the handwheel and get it back to usable condition. I know a little about plastics and I know what ever plastic the handwheel is made of is some sort of thermal molded plastic. Those sorts of plastics tend to want to got back to the original position they were molded in when heated enough to make them pliable. I was able to heat the area in the pictures that I have my fingers on with a small embossing heat gun which is good for heating up small areas like this. Once heated enough to make it shiny in all the areas I needed to reposition I clamped it in place and left it to cool. It worked and the hole is once again in the correct shape and it is very rigid as it was once upon a time. Thermoplastics can be heated enough to reshape and then cooled to maintain that shape without losing much of its original strength. This should work just fine if anyone ever finds themselves in a similar situation. Of course I have more work to do before I can test the repaired handwheel, so I will be sure to report back on how well it actually worked out.

    Be sure to read the FAQ about the shim issues that the BT3000 (not the 3100) had. It could very well be what caused this, and still present on your saw. Pretty well documented on how to fix it though.

      I had already read through and checked the shims. They are in the right position. There is a lot of gunk in that area, looks like oil/sawdust mix. I'm sure someone used oil to lube that and it ended up collecting a bunch of sawdust and other dust and gumed up the works in there.

        that sounds about right.
        good luck on your repair

          Thanks! Lots of great info here for sure! My user name is my YouTube channel name. I have a fishing related channel...mostly DIY fishing related stuff. I fish freshwater almost exclusively and mostly around my home state of Arkansas. Feel free to stop by my channel and subscribe if you like it:

          I actually bought the Ryobi because I have always liked the design/unique features of them and I ran across this one at the right price AND I could use a second table saw to help out with producing parts for the fishing rod building jigs I make and sell on eBay.
          I already have an older Craftsman cast iron top contractors style table saw (I've had it for over 20 years).

          So here I am

          If I do any sort of mods or repairs that haven't been brought up before, I'll make sure to post them for others to see in the future. This is a great resource for these saws.

            This is not directly related, bu when working with the blade adjustment wheel, things can get messed up with just a bit of mis-adjustment behind the wheel.

            Here is a link to the fixing problems behind the wheel:
