First off: yes I know a router does this. But even a cheap 3/4 inch router bit is pushing 20 bucks. I can get circular saw blades for seven bucks each.

This is a proof of concept that I have been thinking about for a bit. I got some beautiful wide red oak for an upcoming project,I didn’t want to cut up to fit in the planer. So I decided to give this a go.

All made from scrap plywood. I have a planing width of 44 inches.

The surface certainly isn’t glue ready but its flat, and a little sanding or planing does just fine.

The wood in there was just a test piece.

That is a new idea. You just have to plane off the high spots and you have a flat board.

So do you keep the saw angled like that while you make the cut?

Very clever. Can you share a photo of the results on the wood?

Cool idea and probably not as tedious as router. I can see running the saw blade over several sections to serve as points of reference and use a electric or hand plane to flatten the piece. Flip it over and make more reference marks; rinse and repeat a few more times and you have flat board. If it is wide enough to go through the planer or sander, you can skip part two. Like it.

Do you clamp the guide assembly with each pass before running the saw sled across the work or does the guide assembly have enough mass to keep from moving while planing?

Very creative! I would point out that the arbor bearings on your circular saw aren’t designed to withstand the transverse loading being put on the blade in this way. But with light passes and occasional use, it’s not really cause for much concern.
