    Raising and Lowering Blade.

    Threads stripped on the motor mount that the raising and lowering screw goes through. Any suggestions on how to fix?

    Check the shims ------ I have a hard time thinking the threads are stripped.

      I have the saw apart the bolt goes straight through. After researching I found a thread that said to use a Heliocoil. I am going to try later today. Thanks for your reply

        Yes, Helicoil is a good way to fix.

        If your only tool is a hammer, you tend to treat all problems as if they were nails.

          Joe I got your message yesterday and after I started replying, we had and internet outage (and my house phone also) before I could reply; lost my answer. It came back on line about 30 minutes ago.

          I was going to mention the heliocoil, but it seems that you have already found that.

            about the size of the helicoil 9/16"-12
            will need a 19/32 drill

            from the BT3 FAQ======================

            Sometimes the threaded elevation rod engages a threaded hole in the motor assembly and the thread is worn/stripped. You will need to enlarge the hole and thread a new helicoil (a stainless steel threaded insert) into the hole to repair the thread. See these elevation rebuild instructions by JohnG.

            [posted by “Knuckles” Brian] I went the HeliCoil route. Thanks to Ed's instructions in the Article section, it wasn't too difficult. It's not something I'd want to do every day. I searched about a dozen auto parts, hardware, and machine shops in this area, and I had no luck finding the 9/16"-12 Helicoil (or clone) kit. I ended up ordering one from a website called Cartools.com. It cost something like $50, shipping included. Wouldn't you know, though, after I bought it I stopped in a local discount tool place that I hadn't noticed previously; they had a clone (Permacoil) kit for $15.

            The next problem was finding a 19/32" drill bit to drill out the lug that the threaded rod goes through. [ed. Note – some helicoil kits include this drill bit]…
            Probably the most tedious (and potentially disastrous) step of the repair was drilling out the hole prior to tapping it. I figured that I only had one shot to drill the hole on the same axis, and I wouldn't know how well I did until "the reckoning" of trying to put it together. I used a 1/2" drill bit to help get the bit centered, and find the axis. I didn't measure the angle, but it wasn't exactly 90º to the table. I had to shim it with some laminated air and a few mosquito wings.

            Once I got the hole drilled and tapped, the insert went in nice and easy, and I epoxied it in place. I made sure to keep screwing the insert tool in and out so that any epoxy that squeezed into the inside threads was "threaded" in.

            I learned something during assembly that's important to the instructions. Install the threaded rod and bevel gears before tightening the screws that attach the motor housing and the guide holder. …
