Significant runout will cause the bit to wobble and leave a ledge like this. You just need to figure out if the runout is in the bit or the router. Should be easy enough.

Do you have a way to clamp the router in a vise and check the flutes with a dial indicator?

I certainly can do some more investigating on the router bit. I will probaby first do a visual on the two cutters to see if one appears shorter or higher than the other. I have several vises in the shop, so I can do that too.

I have not heard back from stew-mac yet, but has only been a day or so. So I will wait another day or so before calling them. I was able to bind #1, so I am not in a huge hurry, but don't want to be working on #2 before getting this resolved. I will also try placing a simular bit in the jig and see if anything strange happens.

I have no experience with the SM kit... I was gently guided towards the LMI set. No brass bushing, etc. First time I used it, zero problems. Were you using the bushing when this happened? (sorry, but I do not think anybody else brought this up)

Actually I did not get the bushing. I will have to ask why. I order the bit seperate and just ordered the bearings I needed, but I thought it came with the bit and allen wrench.

update. after checking the jig and the router I notice the bit wobbling durring the cut. I changed routers and made some cuts by hand. No weird ledge. I do see the bit wobble in the laminate router, so I am guessing a bent collet or router shaft.

Thanks for those you offered suggestions.
