My latest project, and blog entry at http://daves-workshop.blogspot.com/2014/04/a-simple-box-joint-jig-for-ryobi-bt3100.html is all about the Ryobi BT3100, more or less. I created a very simple yet shockingly effective box joint jig for use with the saw. This jig would work with any of the BT3x00 series saws, including the Craftsman variants 22811 and 21829. I suspect it should also work on the BTS-21 as it shares a common sliding miter table / fence arrangement. If you have a Ryobi table saw, with a sliding miter table that uses the same extrusion / fence with the T slot on the top of the fence, you can use this design. It is very simple and straight forward. I know other MFGs have used SMTs as well, although Ryobi is well known for it...


My first box joints using this jig, are surpisingly clean, snug fitting, and accuate. And yes I intentionally left the tails proud of the surface...

I had to remove material to clear the star knob on the back side of the 3/4 stock, this was done with a regular grinding stone on a dremel. Not super pretty, but I have plenty of clearance now!

The indexing pin is a 3/8" walnut scrap that I attached with a finish nail with my air nailer, and Titebond III. The spacing in to set my first cut / align the jig to the dado stack is just the cutoff of that same piece. Very effective, very affordable to do!

I have a LOT of projects I need to work, and I feel this setup should allow me to produce some drool worthy joints.


I need to grab some cheap stock to practice with, and set up the dovetail jig, both the MLCS and Harbor Freight jigs, and my box joint jigs, and just build boxes. Mostly to build skill more than boxes.


Once I am more comfortable with making these joints, I need to get very, very busy building things, to start off with, drawers, and a lot of them. I am going to reface my cabinets through the house, and in the process also replace the lousy butt joint and brad nail drawer boxes the builder used... I already have the bits I want to use for the doors which is the MLCS #8782 mitered door frame bit, and I have the matching cove bit. It's a squeeze, but I have fabbed up a sample drawer front using this bit set out of pine. Looked great. (Should have taken photos of it, but didn't think about it sorry...).


My first priority though should be a shadow / display box for LOML's wedding "stuff" (bouquet, garter, veil etc...).

i've subsequently moved on to a powermatic but for years a BT3000 was my tablesaw. a little underpowered but accurate and reliable little saw that held up to lots of use. i have fond memories of it and got a smile when i read your message.
continued good use of your BT3x00.
