Modifying Bosch RA1054 edge guide
I'd like to route a dado about 16" in from the edge of a sheet.
Being perfectly parallel to the edge matters.
The RA1054's guide rods aren't long enough to do this, so I'm considering replacing them with a pair of longer steel rods. Per my micrometer, the rods are 9.65mm in diameter which seems an odd size. Switch to imperial and they're 49/128"... close enough to 3/8", which should be easily obtainable. (googling "49/128 inches in mm" yields 9.72mm, surprisingly far from the measured 9.65)
1. Are there any hidden traps for a router newbie in doing what I have in mind here - either the jig modification, or using it this way?
2. Has anyone already done this and can point me to rods that work?
I recognize that operating farther from the edge make the edge guide a bit more likely to shift and not stay square to the edge, but I think that's probably manageable at 16". In case it doesn't feel good, I may oversize the new rods to allow 18" depth, then use that extra 2" to fasten a longer fence into the edge guide.
It may be less hassle to simply build a single use edge guide for this operation... take a 12" x 24" sheet of 1/4" plywood or hardboard, mount the router at one end, attach a fence beneath the other end.
All input is welcome... especially the kind that saves me from errors and hazards.
