Im currently making a jewelry box tray and was trying to route a rabbet for the bottom of the tray. It screwed up my pieces and I’m not sure what I’m doing wrong. I started with the router speed at 5 and lowered it down to 1.

Are you feeding from right to left? Also try and take less wood out and work up to your final depth.

Yup right to left, also only taking out an 1/8”. I figured since it’s so little I could do it in one pass?

I’d route first and miter last

You’re going to get nine thousand different answers and suggestions on this…...Here is mine…..

1. Move the fence forward and take smaller bites. Move the fence back in small increments until desired depth is achieved.

2. Use a backer board when running any kind of profile.

3. Speed on that bit should run around 12,000 to 15,000 RPM

That should fix the problem.

Yes, I defintely will route first and miter last next time.
How do I know how many RPM when the settings are numbered in single digits?

I’d be doing that on a table saw with a dado blade…......easy pleasy in one pass no tear out.

I’m trying to understand how you got the cut we see while feeding right-to-left. Thinking maybe you ran the pieces on edge, freehand, without having the fence in line with the bearing? And the bit grabbed and climbed into the mitered section? (Hope your fingers were out of the way. That would be a dangerous approach)

Better to put the fence in line with the bearing (use a straight edge to keep everything in line) and keep the material against the fence at all times.

When ever jointing,planing,or machining wood ,you have to pay attention to what’s called grain run out(grain direction).If you don’t,and you machine against the run out,you take the chance of tearing out the grain.Where it can’t be helped you were better off starting with a shallow saw cut first.

I hope this helps
