Something I came up with today, to make the bowl sanding operation a little less labor intensive.

The pictures pretty much explain it.

Looks like you had better wear an arm guard. I thought you were going to rip your arm open and bleed all over that purdy RW.

One thing I've noticed with this jig though is the inability to tilt the dish forward for the back sanding. I used one very similar but the middle post was able to swivel and tilt forward and back allowing the dish to sit nicely... maybe yours does that I just can't tell.

Good observation John, the jigs does not tilt. What I do for the back is raise the body form at the neck end with a pair of wood blocks..

Good move Lance! The Borges Guitars shop has a similar rig, with a tilting center post as John mentioned. It's a great jig...nice work!

Hey, are we gonna be calling you the New Jig Man soon?
Now all you gotta do is motorize that puppy...Don W38369.2792476852

Very nice Lance. I was gonna do something like that but after my last bout with sanding bowl induced tendonitis and Tim's arcitle I decided to motorize. Here is mine based on Tim McKnights great article in Guitar Maker Magazine. The only other thing I did was add the four threaded rods outside the bowl which allows me to adjust the height I want it sanded to. Ya just set the height stops turn it on and when the mold rests on the stops it's finished. Then you can just glue in the linings and set back in place before you make any changes and a couple minutes later it's ready for the top/back to be glued on.

I am building one similar, however, my disk sits on top of the rim. As the disk spins you can place hands on disk to put pressure at needed places. I mark the rim and kerf with chalk or grease pencil and let it spin few times turn off and look at rim. Can easily tell where need to apply pressure. I do rims (at school this was called parabolic sanding, have no idea what that means)with no kerfing in and then after kerf do it again. The box sit in mold and lower bout on a ledge that is adjustable so sands even. Have pics of it if anyone ever interested. Have no plans though

I was going to build similar to Lance's design. (Good stuff Lance.) But after reading this I think I will go motorized. I really like what you have done with the bolts for depth guage John!! Good job Guys! Except all this knowledge I have to build more jigs and experiment. That means less production at the moment. Oh well I know it will pay back greatly.

Jigs mean a break in production followed hopefully by a sharp increase in both production and quality.
