Turning off BT3*00 from left side; another view
After reading Ed62’s article I was invigorated. During my first use of my new 21829, I felt the need for left side turn off and Ed had supplied an answer. I sat before my saw and considered Ed’s solution. Good, but I thought I saw another approach. I wanted a switch that could be easily added or removed, one that interfered with saw function to a minimal extent and one that could be adjusted to eliminate any slop in my construction efforts. (This is important; I received my training as an electrical engineer. Forced to take an entry level mechanical engineering course (ME101) I flew through the statics part and barely escaped after dynamics). Besides, I didn’t have any PVC pipe in my shop.
Fortunately Sears (read Ryobi) has provided a plethora of opportunities for customization. Notably, in this case, the one inch T-channel on the bottom of the front rail. By attaching a hinge to a slide inserted in this channel I was able to construct a cutoff switch, which met my requirements. I selected a piano hinge because it could be mounted flush to the slide and the dimensions were appropriate for the narrow slide. To the hinge I mounted two pieces of aluminum, one to carry a bolt used as a finger to push the switch and another to aid in support of a bar for throwing the switch to turn off the saw. A long, but narrow, push bar was added attached to the aluminum supports. Job done, all else is details.
Materials
Slide 1”x 1/8” x 4” steel
Hinge 1 1/16” x 30”
Support 6” x 3” x 1/8” Aluminum
Support 3” x 3 “ x 1/8 Aluminum
Push Bar 6’ x 2” x 1/2” walnut (or what you have)
Hardware #10-32 x 3/8” screws, nuts and washers (used as spacers)
Clamp screws (2) 5/16”
Finger 3” x ¼” bolt + nut and plastic end cap
Tools
# 10-32 Die
5/16 Die
Drill or drill press, drill bits
Hacksaw (for steel)
Jig saw (for Aluminum)
File (to smooth edges of metal)

by LCHIENSmall 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)...-

by LCHIENAfter 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...-

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...-

by twistsolRipping 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

by LCHIENBT3000 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...-

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...-
