Thread: Mitring plywood

Sorry, I meant a bevel cut along the board.

Personally, if the saw can do it, I'd pull the saw from the wc and set it up to rip at 45 degrees freehand (using the saw's own guide). This way you are moving the saw through the job and not the job through the saw.....so the plywood can be clamped to a bench and be nice and stable which it may not be if you are wrestling with it over the wc.

Ditto with the router....

If you are not already familiar with manoevering big bits of timber over the Bevel Ripping Guide, then I'd recommend SBD's post about using the/a saw with a guide clamped to the sheet. If you have the router table top, then you could use a 45 degree bit in the router to put the final 45 on a precut piece.

I have found if you are not totally in control with the BRG, then the timber can rock a bit and you get a far from perfect edge, and the taller the piece the more likely it is to happen.

Personally...

I rip the timber to width, and then put it through the router table with a big chamfer bit. The work stays flat (well as flat as a RTA300 can get), and your back in control. I know is double handling, but its safe and accurate.

Thanks everyone.

I know it can be done on the bevel ripping guide (seen it done by a demo guy) but I think I need a lot more practice before I can get anywhere near the consistency I require.

I think I'll go get a chamfer bit and give it a go. Also having the mini-extension table, I guess I could easily mitre long pieces that way.

Ditto here. I had to build 3 box columns for a kitchen breakfast bar, about 10 inches square from 18mm MDF. Ripped the MDF to width on the WC, then used 45 deg bevel bit to bevel the edges to 45 deg on the router table. Perfect square columns resulted, found I had absolute control over the work this way. Final box column then had 3 vertical flutes routed in each side using handheld router.
