on a volume basis, it is a big investment. you can't fletch volume with one or two jigs, you need dozens of them, because everyone waits 'till now, to get new arrows for deer season.
the shop i used to shoot at years ago in West Allis, WI, had a big 'lazy Susan", about 4 ft. in diameter, with 48 bitz's mounted around it's periphery. i always thought that was a slick set up !. that shop, was owned by George Stadtler, the guy that made "Astro" bows, way back when. his manufacturing was in the Onalaska/La Crosse area, but he had the parts for "factory custom orders" shipped to his shop, in West Allis, for assembly. in the back of his shop, there was a wall, lined with small 4"x4" cubbies, that held all the risers and limb sets and a work bench at the bottom of it, where he would sit and pick the parts to build custom bows. a friend of mine bought the shop from George when he retired, and i had the pleasure of building my own "custom Regency" from parts that were still there, out of that very building station.! that shop was an old bowling ally and the "automated bunks" traveled up and down the allies with their wheels in the gutters, for guidance. one of the very first examples of automatic bunks, around.
doesn't sound so exclusive, today, but at the time, George was a innovative guy, in the archery world !.
