    Notes on "Ripstrate" used with Ryobi BT3000

    The Ripstrate is a nice tablesaw add-on (www.trend-lines.com, part # RS1, $39.95). It does three things: Holds the work down, pulls the work towards straight towards the rip fence and provides modest anti- kickback protection. I had previously used “Board Buddies”, but have since abandoned their use in favor of this solution. Below are notes and pictures on my installation.

    Ripstrate installed on auxiliary fence and being used to secure a piece of 1” thick UHMW that is being ripped (actually, this was taken right after I finished the rip...I just placed the pieces back together.)

    1. Spring provides downward and rightward tension
    2. Wheels hold work
    3. Anti-kickback “brake” keeps wheels from turning backward
    4. Work thickness adjustment (keeps wheels from slamming down when work passes completely by device). This is just a hex bolt that forms a “stop” to keep the arms from descending to the table.

    Note that wheels and device are angled slightly towards the right (by virtue of holes in fence being drilled slightly out of parallel alignment). This causes the work to always be pulled towards the rip fence.

    I’ve made a 2” thick aux fence out of some Oak scrap. The aux fence bears most of the support burden for the device.

    1. The device is supported by the aux fence and a clamping bolt (wingnut) on the right side of the fence.
    2. In addition, I have added a clamp down bolt/plate to keep the device stable and horizontal.

    Parts:
    • The device comes with the wheels, spring and mount. Additions:
    • Auxiliary fence with 5/8” holes drilled to support mounting studs (note instructions say 1⁄2”, but I found that the studs were thicker than that.
    • “Wedge” piece goes between wing-nut clamping bolt and fence. I decided to make a wedge to keep the device angled to the right as it’s supposed to be.
    • Aluminum plate sized to drop into top of mount. I use a know with stud and tee-nut in fence channel to keep device stable and horizontal.

      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

    • 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...
