  • BT3000 - Crack in Saw Table Casting - Repair or buy?

    Trying to dust of and setup my old, often moved, and rarely used BT3000, I found that it has a crack in the saw table. On the back left side, where the back rail is connected, I found a crack. Can it be effectively repaired? Or should I pay the 80 bucks for a replacement?

    Help???

    I am trying to get rolling on woodworking after a parent and job induced layoff.

    Thanks,

    Mike

      Or drill a few holes and add an external/internal doubler of metal with screws. If you get at least 2 screws on each side of the crack going through a stiff flat metal bar it'll hold the alignment just fine.

      Also, brazing cast aluminum is a LOT easier than any true welding process and the results are almost as strong. Brazing can be done with the right "filler" material and a plain old propane or MAPP gas torch. MUCH cheaper stuff than TIG welding equipment which is generally used for aluminum welding (though MIG can be used too with the right wire material).

      You JUST reminded me of some material that has been at MULTIPLE shows locally, but could be purchased CHEAPER, for the same thing, at Northern tools. ( Item# 11070)
      BAC Industries Propane Torch Kit for Welding Aluminum, Galvanized Metal and MORE, Model# AP201

      welding cast alm.

      The casting is a painted surface.power coat I think. tring to weld cast is extremly hard.your chance of a good job is prob 50/50. the cost of the weld job probaly would be close to the price of the top replacement.

  • Screw friction products EZ-Grip and Screw Grab?
    by LCHIEN
    I was reading an article about fasteners the other day.
    They mentioned a couple of products I had not heard of before:

    EZ-grip and Screw Grab

    Apparently if you have a screw that you have a hard time engaging like a worn Phillips, a drop of these products will increase the friction between the screw and the driver 8X it is claimed so that you can back out the screw.

    You can find them both at Amazon.
    Not cheap 5 oz of EZ-GRIP is $20; 1/2 oz of Screw...

  • Lonnie's No Measure Alignment procedure
    by Lonnie in Orlando
    Hi Guys - I haven't been on the forum much lately ... I bought a '55 MGTF-1500 that is taking up space, time, and money that is(was) used by my woodworking shop. The car has a wood frame beneith the body panels, so I guess it counts as woodworking. Thanks for resurrecting my No-Measure alignment thread. I see that it has lost some of the attachments. So I reposted it below. Note - there are a lot of good ways to adjust a BT3K or any other table saw. This is the one that I found is best for...

    by Black wallnut
    Since it seems time for my semi-annual maintenance and due to several posts asking how to lately I deciced to take pictures during mine. Keep in mind this is specifically for the BT3000 only.

    Step 1: double un-plug saw at outlet and onboard outlet. Remove throat plate, Sharkguard, Big dog clamp, and splitter (or the stock POS []). Remove blade and spacers.



    Step 2: remove left side cover and dust shroud.



    Step 3: remove the four...

  • BT3000 To 3100 Shim Upgrade
    by crokett
    Upgrading the shims avoids the issue of the BT3000 shims dropping out and causing the blade-raising mechanism to bind.


    Before you begin:
    Call Ryobi technical support at 1-800-525-2579 with the serial number from your saw to
    verify that your saw is eligible for the upgrade. Some earlier BT3000s are not.



    ‘Right’ and ‘Left’ designations assume you are starting by looking at the front of the saw.
    These instructions assume a stock
