The Amana AGM raised panel set I’m using has a back cutter and came set up with a large bearing.

Everything turned out great, but I did think that the depth of the Ogee wasn’t quite what I thought it should be and the panels don’t drop into the styles very far.

The instructions that came with the set seemed great, but did not include any illustrations or reference to the back cutter feature. So I used the bits as they came set up from the factory…...... WRONG!!!!

So I go to Amana’s web site tonight and find a brochure for the raised panel set with the back cutter and it turns out that there’s a smaller bearing that came with the set, which I should have used.


Bad news… I’ve finish sanded and sealed three of the six panels already…

Good news… The router table is still set up at exactly the correct height, so I can swap the bearings and cut the deeper Ogee.

Bad news… In order to prevent tearing out the trailing edge when routing the end grain, I backed up the panel with a piece of scrap and I cut both end grain ends first before cutting the long grain….

BUT HOW CAN I BACK UP THE END GRAIN CUTS AND PREVENT TEAR OUT NOW THAT I’VE ALREADY ROUTED ALL FOUR SIDES?

Needless to say, I’m pretty frustrated and do not want to lose these panels or have ugly tear out on each one.

Any ideas?

All I can think of is to borrow a contour transfer tool from work…

transfer the existing Ogee contour onto a scrap block as best as I can, cut the contour on the band saw and then use that scrap block to back up the end grain cuts.

Matt, you should be able to do another deeper pass using the smaller bearing just the same as you would any multiple pass using a large bit. You are still cutting all 4 sides of the panel which would take care of any tear-out from the previous side…..

Not sure what to tell you about the ones that are finished. You’ll probably have to go back and refinish those surfaces that get cut with the new setup. As far as a backer board goes, I never use one on raised panels. If you start with the cross grain cut (which you always should with any profile), any tear out will be removed by the long grain cut. Give it a try on some scrap and see.

Doesn’t answer your question, but I wonder why we need back cutters since most of us now have planers that easily make 5/8” thick panels. The only reason I can think of is if you must use 3/4” material. I don’t prefer the appearance of panels that have the back cutter cove, though tastes may vary, of course.

Back cutters are for when you want the raised panel appearance on both the inside and out…..

Rich is right, do the end grain pass first. Should be fine.
