Been using some of my "lung breather" time to upgrade fixturing. (Don't seem to be allergic to aluminum and UHMW
) I've seen pics of this type here on OLF but can't find the thread. Anyone lead me to it? The last photo looks like the router is drooping--trust me it isn't. The indicator mounting holes are normally used to mount a dust collector shoe on a CNC router.Construction is 1x2x1/8" wall mounted at 45 degrees and 1x1x1/8" wall for the parallel links with 3/4" CR steel shafts running in UHMW for the pivots. The bracket holding the router is one I had on hand from K2 and a Bosch 1617 EVS router.
The two curved links at the top are to allow the arms to fold back next to each other while clearing the gas cylinder mounting. The black plastic knob is an adjustable stop to hold the cylinder extended for an extreme up (non-working) position. The cylinder balances the full size router and the upper hole could be used for a lighter trim router. I use a bearing collar that runs on top of the guitar body which controls the depth of cut. Another bearing collar below the tri-wing cutter sets the width of cut. The bearings mount to a custom arbor. (I've used this bearing setup for a number of years)
The next step in this project is to make the mounting/clamping blocks to hold the guitar body. Planning to use aluminum t-slot bars attached to the table top to adjust the position of the clamp blocks.
I figure I can always sell this setup to someone if I end up not building any more archtops. I enjoy building fixtures like many of the rest of you guys.

, with a tool like that you have to build more arch-tops. Looks like the trick for routing bindings, right? Might be a market there.
