I am using a plunge router to cut crosses in boards. I have been using a 1/2" spiral carbide bit, but the finish cut leave rough and occasional burnt spots - especially in maple. I've been cutting these crosses in box lids for soup kitchens, churches and assisted living places. I have "Prayer Request" engrave along the cross.
I use a guide bushing that is .625" outside diameter. If I used that for the original cuts then swap out that bushing with one that is say .615" I believe the router bit would just be taking off a tiny bit of wood and clean up the cut.
Years ago I was using a 1/4" router bit and purchased two brass guide bushings. One is .434" and the other is .442". By using the .442" bushing first then by swapping to the .434" with the same router bit it would shave off just a tiny bit of wood. I have no idea where I purchase those guide bushing.
I went to a machine shop today and show them what I was trying to do, but was told they couldn't shave any off the current bushing because there wasn't enough metal there.
I tried using a 1/4" spiral bit with the two bushing that I have (.434" and .442"), but the bit isn't long enough. It is 2 1/2" long, and would require around 2 3/4" to 3" long bit.
Does anyone know where I could purchase guide bushing around 5/8" and another either slightly larger or smaller or a 1/4" spiral bit that is around 3" long?
Here is a photo that I posted earlier showing what I am trying to accomplish.
