After years of making the same part repeatedly on the CNC router, I finally decided it was time to make the router load it’s own material.
Friction is a valid way to hold a part for routing. That is how most vices and clamps work. The key here is to calculate an amount of friction that will resist the cutting forces while at the same time keeping it low enough for the router to be able to overcome it while loading and unloading.
I’ll post more on this when we have it working. For now, here is a cool picture of the jig.
At Sinking Valley Woodworks, we take on odd jobs from time to time. One of these odd jobs was some car parts for an old Bentley restoration. Wood was a much more common material in cars in that era.
This particular piece is what goes at the top of the windshield and connects to the roof. It has curves on all faces, and compound curves on most. The new part was made out of Ash, carved on a CNC router, and finished by hand.
