I am having a little trouble centering my router on a table insert.
I picked up a Skil 1825, and a Freud Universal Router Table Base (the black phenolic one with the red and grey inserts). The problem is that in order to mount the router, I have to use the router baseplate as a drill template, and centering it on the table base after removing it from the router is pretty much a hit and miss operation.
What I did so far was:
- unscrewed the router base
- put a Freud guide bushing (3/8" ID) into the table base insert
- mounted a 1/4" pilot bit in the router collet
- put the router and base on the table insert, with the pilot bit centred in the guide bushing as best I could
- Taped the router base edges to the table base
- Clamped the router base to the table base
- drilled and countersunk holes (with drill press) using the router base mounting holes as guides.
I think I may have let something slip a bit, and perhaps did so even after I drilled the first two or three holes. I can just get the router attached to the table base. It's difficult because one or two of the holes are visibly offset after I line up two of them.
The end result is that when I put in the 3/8" ID guide bushing and the
1/4" pilot bit, the bit is in contact with one side of the ID of the guide bushing. So, it's close, but I want it closer.I am considering messing with one or two of the holes I drilled, perhaps enlarging the appropriate holes to try to swing the centre into alignment, or perhaps drilling another set of holes after rotating the router a bit.
I am also considering through-drilling the threaded mounting holes and tapping them for 10-32 (8-32 in there now). This way, I could centre everything up. then drop a bit down through the drilled out holes and starting a hole in the table base by finger twisting the bit..
I might even be better off turning a hunk of aluminum with a 1/4" or
1/2" 'shaft' and a shoulder the right size to fit the opening in the Skil base.Anyway, I have seen some great answers here, and wonder if anyone might have a suggestion as to the best way to proceed.
Thanks, Larry
