I’m making a wooden bread box door on an X-Carve. The top and bottom edges need a 10° angle so the door tilts inward when opening.
What’s the best approach? Any tips for clean results on ¾″ solid wood?
Thank you!
I don’t think this makes sense to do on the CNC, assuming you have access to a table saw or any normal router. The setup time to swap bits (if you can even get one that will work) and configure the path would likely outweigh any benefit of doing it on the CNC vs a manual pass.
The best bet would be to cut the panel out on the CNC, then run it through the table saw with the blade tilted. Should give you a clean face and be extremely quick, even for a one-off. In theory you should be able to do both sides with the same fence setup (though there might be a little variation if the edge isn’t riding on the fence cleanly).
The second best would be to use a router table with a fence, but I don’t know how reasonable it would be to find a 10º / 80º chamfer bit big enough for that. I think you could find a 15º bit, though. Be very careful of blowing out the end with that being all end-grain. You might need to build a jig with a sacrificial edge.
Another fairly easy option is to sand that in by hand, if you have access to a big enough belt or disc sander with a tilting table. Just score some lines in to help you know where to stop (or use the flush edge if that works).
You might even find it’s pretty fast to hand-plane the edge, since 10º is very shallow. But that appears to be all end-grain, so it could also be a real pain. And you’ll again have to be cautious of end grain blowing out.
If you can’t do any of those, another option would be to use the Super Gradient Generator app within Easel to generate a stepped edge, which the CNC will try to mimic as best as it can. Afterwards, you can then hand-sand or use a hand-plane to even out the final surface.
Personally, I really hope you have access to a table saw, because that would be extremely quick, safe, and provide the cleanest result with very little setup.
