Advice on how to make a specific dado cut

I’ve got it.

Take the board you are going to make the plate out of, 10” x 6”. Joint and and plane it flat. After it’s it’s parallel, NOW make your dado cuts before you do anything else.. After that, use a horizontal table router table to cut your 12 degree bottom angle. Kinda like a raised panel.

Now, if the bottom is not like and upside down raised panel, but flat, and you want the 12 degree dado’s, try this. Take your board and pencil your dados on the end. Set up you table saw to the proper depth. Get your protractor or whatever your making the angle with.

Place your plate board against the fence. Now, with a scrap piece of 1/4” board, raise the plate board, slip the scrap under the plate, and adjust it until the plate is at 12 degrees. Mark the place the scrap would be. Now, use some double sided sticky tape to secure the scrap in place. Make your dado cut. The scrap will of course need to be parallel to the blade, and long enough to reach past the blade.

Does that make sense? Let me know if it doesn’t and I’ll try again! ;)

Im not quite getting a grip on your description but could you do the dado with an angle adj. base router ? Or just stick with red meat.?BTW I dont think a dado is what your after is it ?

Me neither. A picture would be worth 1000, no 10,000 words in this case.

Actually, I re-read it again and think I understand part of it. I would tackle it with a glue-up. Bottom is then perfectly flat with no tool marks. Like this:

-- Backer boards, stop blocks, build oversized, and never buy a hand plane--

If you go with a common dovetail angle (14 degrees maybe) You can cut one side with a saw blade cut then finish the dado width with a dovetail bit on the router table

Nibble….away. It won’t take long.

You can make a “Stumpy” horizontal router table…. It is definitly worth the price for the plans and when you’re done, you can still make a ton of stuff with it.

I am glad someone had the answer, let us know how it works out

The good folks above have already given you a number of good, effective techniques. I’ll give you one more.

Cut the dado at the 12 degree angle with either the table saw or router table. You can make a carrier jig to hold the wood at the 12 degree angle on the router table or tilt the dado blade on the table saw.

Then cut a triangular cross section (12 degree angle) length of wood that will fit in the bottom of each dado and glue it in. Just another thought.

Nibble it out with the TS and finish with a sharp chisel.

Nice solution, Riverwood!

I also like Firehouse’s and riverwood’s methods.

@ Jonathan – that’s exactly what I meant. Sorry, folks, been away from the computer for the evening…I’ll read up right now!

Thanks everyone! I love Riverwood’s solution…seems easiest. And Thanks Jonathan for the graphic. Perfect@ I’ll post pictures when I’m done!

I think the nibble and chisel method is the best; maybe not the quickest, but less chance of screwing up.

Riverwood & Jonathan’s suggestion worked perfectly! Yay! Thanks, everyone!
