    BT3000 Safer Power Switch Modification by Jim Frye

    This add on to the BT3000 came about from a question on the tool forum concerning problems turning the saw off in an emergency situation. I have “missed” the switch cover many times because I was concentrating on the spinning saw blade, the work piece, the cut off, and my left hand. The stock BT3K switch cover is only 2.25 square inches in area and positioned where it is, can be a difficult target to hit the first time. There is a large switch on the market that measures something like 12” square, but my tool budget is a bit pinched. I came up with what amounts to an extension for the stock switch cover. I used a 6” wide by 10” long piece of thin rigid plastic. This produces a larger target of 60 square inches. This could be 1/8” plexiglas or thinner also. It doesn’t have to be very strong, just stiff enough to cause the switch to turn off when struck. It also can’t be very heavy or it will turn the saw off by it’s own weight. This cover extension is mounted on the existing cover with double sided carpet tape. This tape has fabric in it and is very strong. The extension could also be mounted with small screws and nuts if they were positioned to clear the switch mounting screws under the cover. The extension is mounted with 1” of it above the existing switch cover and centered on the cover. The bottom of the extension is then flush with bottom of the upper horizontal stand rail. This arrangement allows the entire cover to be raised to turn the saw on, or to remove the screws that hold the switch in the cabinet. It’s easy enough to slip your hand under the cover and turn the saw on without completely raising the cover. The larger surface area of this cover makes it easy to blindly reach down and shut off the saw with out looking.

      Small T-nut for the left side of BT3 rip fence or front of miter fence (Article Version)

      11-30-2023, 04:00 PM
      I have found a perfect T-nut for the front of the BT3 miter fence and for the left side of the rip fence (same extrusion used both places)

      Its actually a weld nut, but fits the T-slot described above.

      Weld Nut: #10-24 Thread, Tab, 1/32 in Base Ht, 3/8 in Base Wd, 5/8 in Base Lg, Steel, 50 PK
      Item 1LAJ3 Mfr. Model 1LAJ3​ (WW Graingers)...

    • Special DIY T-bolt for BT3000 Miter Fence, Rip Fence and Rails
      by LCHIEN
      After a bit more thinking, some universal T-bolts for the rip miter fence make more sense than fixture blocks.
      The two big slots in the rip fence and the miter fence and the front and rear rails are sized to take 1.00 inches wide x 1/8th and 1-1/8" wide x 1/8th.

      So I took some 1/8th flat Aluminum 1.00 inches wide and cut 1-1/8" long to make a 1" x 1-1/8" rectangular plates; I used a short rip fence Block to space the length but not cause a kickback with the...

    • How to make a BT3x00 Rip Fence/Miter Fence fixture block for mounting jigs
      by LCHIEN

      DIY BT3000 FIXTURE BLOCK for Rip/Miter Fence extrusion

      Simple shop construction - no machining.


      This is intended to fit the top T-track on the Rip and miter fence (uses the same extrusion) on the Ryobi BT3x00 / Craftsman 22811 family of saws
      You must make the Block and Base parts; you can make them 1.5" or 3 inches long or modify to any other length.
      Make the base from 1/8” aluminum bar, you can get 1.5”, 2”, and 3” at Lowes...

    • Another Thin Strip Jig
      by twistsol
      Ripping thin strips can be accomplished in a number of ways, but this jig is the best I've found so far.

      • There is no need to move the fence so every strip comes out exactly the same.
      • It is incredibly easy to build
      • It keeps your hands well away from the blade the whole time
      • It keeps control of the strip you are ripping all the way through the cut and past the blade
      • It doesn't interfere with the blade guard.
      • You can cut strips from any length of stock
      In the starting position,...

      BT3000 tall rip fence

      09-12-2021, 07:58 PM
      I have had a tall BT3000 fence for a number of years, I should have used it a few days ago but I didn't because it was too much trouble, And I paid the price as the tall item was a little unstable and I had a hard time controlling it as the two pieces separated and wallowed out a bigger kerf than I wanted at one place.

      Anyway the BT3000 tall fence is generally held on by the T-slots in the side of the rip fence. This is...

    • Extending rails/rail profiles
      by LCHIEN


      I am finally going to use my BT3000 extension rails.
      My objective is to have some easily attachable rail extensions rather than a full time wide BT3000 using two full rails taking up a lot of space and requiring table support under the right side as many do.
      I just want some wider support but not to do full 4x8 sheets of ply... if I need that, I'll break the sheet down on some sawhorses with a circ saw and some guides.

      I think I am going to cut my extension...
