Dust Collector Pan for BT3000

    Dust Collector Pan for BT3000 Designed by Jim Frye

    This project is the result of an attempt to create a prototype for a dust collector pan for the bottom to the BT3K cabinet. The idea here is to keep the dust from falling onto the items stored on the lower part of the saw stand. Since I have been planning to enclose the saw stand with a wood cabinet, I wanted to use the space below the saw for tool, blade, and jig storage. An additional goal was to improve dust collection inside of the saw and above it also. The aim is to collect more dust inside the cabinet and hopefully extend the life of the motor and other mechanisms in the cabinet by keeping it cleaner. The use of a dust collection system or shop vac is essential when using this pan. There are no drawings for this project. I created it on the fly using a ruler, utility knife, hot melt glue gun, and some corrugated cardboard. The pan completely covers the bottom of the saw cabinet. The pipe sticking out of the back of the pan is a piece of an old shop vac wand and is used to clean out the collected dust in the pan with a shop vac. The pipe is normally plugged with an empty 35 mm film canister. The pipe extends far enough from the rear of the pan to clear a planned wood cabinet enclosure. The front and rear flanges of the pan are 2 1/2 wide, which is the same width as the saw stand angles. These get clamped between the stand and saw cabinet when the saw is bolted to the stand. The flanges on the sides are 1 wide and creased to be folded in half to 1/2 width. This way, they seal under the cabinet sides better. I designed this pan with 5 1/2 of drop at the rear so that the clean out pipe would clear the out feed table mount that is bolted to rear of the stand.

    The first piece I made was the rear. It is just a triangle with the 2 1/2 flange on the long side (top edge) and hangs straight down at 90 degrees to the flange. The remaining two sides connect to a 1 wide bottom. This little flat allows the clean out pipe to sit closer to the bottom of the pan. A 1 wide hem is left on the sides and on the 1 wide bottom for attaching the side and front panels.

    The two side panels were made next. They are mirror images of each other, but are the same size. The top edge of these was made to fit between the top flanges of stand. This top edge has the 1 flange that is folded in half as mentioned above. Since the side panels are right triangles, the rear edge of them is same length as the sloping lower edge of the rear panel. The lower edge of the side panels has a 1 wide hem added to it for joining to the front panel. I assembled the rear and side panels upside down on the workbench to ensure everything remained square. It helps to have some weights to hold things in square while gluing the joints.

    The front panel is the same width as the rear panel and has a 2 1/2 flange on it. The length of the remaining edges of the front panel is the same as the lower edges of the side panels. The front panel also has a 1 wide edge at the bottom to mate with the one on the rear panel. The two lower edges of the front panel have 1 wide hems for joining to the side panels. In these joints, the hems on each panel overlap onto the adjoining panel surface. This gives the bottom of the pan a double width glue seam for extra strength. The front panel was also glued to the assembly on the workbench to maintain alignment.

    After the pan was all glued together, I did a test fit in the stand with the saw unbolted. You have to remove the saw from the stand to install the pan. After trimming a few stray bits here and there to clear bolt holes, I took the pan back to the workbench and ran a bead of glue down all of the exposed joints (like a weld seam). I finished the pan with a spray coat of automotive silver paint and three coats of wiping varnish to make the cardboard less of a dust catcher. This resulted in a lightweight, but very stiff assembly. Im sure a sheet metal pan would a better solution, but this was a prototype to test how well it works and it only took two hours to create.

      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.

    • 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...

      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...
