    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.
    Click image for larger version  Name:	weld nut.jpg Views:	0 Size:	114.8 KB ID:	857152
    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)

    The fence slot is .400" high and .200 deep. The T-nuts are 0.375" high so they fit nicely with an adequate but not sloppy clearance. About .1" thick and the protrusion fits in the slot on the fence. The hole is threaded 10-24 a common screw size (10-32 is also common but this is 10-24).
    The closed back of the slot means that the screw length is limited.
    I use it for attaching a sacrificial rip fence face or a tall fence or a long rip fence. and for the miter fence you can attach a long miter fence with stops.
    If you use a 3/4" thick 1x2 or 1x3 or 1x4 board then a counter sunk 3/4 or even 1/2" screw will work nicely.
    A countersink of 1/2" depth and a 1/2" screw will bury the head in the fence out of the way. Best to try and adjust deeper if needed.
    Final note, I drill the hole for the bolt and nut 15/16ths up from the bottom of the fence being installed. This leaves 1/16th clearance so the fence does not drag.

    I bought a pack of 50 of these which is way more than I need, but they're kind of hard to find except at the specialty industrial stores and shipping tends to be high.
    If you want 2 or 4 of these, drop me a PM with your address and I'll mail you some in the interest of promoting the saw.
    ​A pair of these nuts should easily hold a auxiliary fence as I described above.

    End-on view of T-nut entering rip fence; note I have one of the metal roller holder replacing the original roller holder. I found it was easiest to take the rip fence off the saw to install the T-nut rather than install in position where you were kind of blindly feeling for the slot.

    At the hardware store today I picked up these 10-24 x 3/4" set screws. With a spot of super glue (or even blue loctite) they will turn into true T-bolts.
    This will be much easier to thread into the slot in the fence then locate the mounting holes in the auxiliary fence over the jutting out stud. A half inch deep recess maybe 3/4" or 1" diameter will allow me to put a 10-24 nut over it easily.​

    • 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...
