First, if this belongs in the section on tools and jig tutorials, can it be moved?

I have a 4" belt sander/disk sander combo, and need to thickness my headstock and to thickness sand the veneers I have for the front and back of the headstock. Headstock is mahogany, the two veneers are ebony and cocobolo.
I searched the tools/jigs section without any luck, but would appreciate pictures and maybe even a how-to about making a jig to place by the belt sander and slide the headstock in and out. I figure if that can be done, I can use double sided tape on the veneers and a straight board to attach them to in order to get them thinner.
I appreciate any and all help - especially with lots of pics.
Thanks,
Bob

It can and has been done did by others including myself once upon a time which was a long time ago and as such just don't remember how any more. It worked, but I do remember it was a lot of hassle and so built me a thickness sander which was a hassle of a different flavour. But ya...it is possible.
Suggest you suck it up, save self the hassle and just purchase ready thicknessed plates.

Run Google and youtube for info and pics of thicknessing jigs with belt sandes.


thus spake duh Padma

After making the basic unit with a floating support I sanded a board in it and attached it to the base for the actual sanding support surface so I knew it was co-planar with the belt.

I free handed it... first I glue the headplate on, then carefully thin it down with a jointer, and then just pressed it against the belt... not the most elegant solution but it works.

I am with Tai. I get the top surface of the head true with planes, checking with a square for flatness and correct plane with the rest of the neck. Then I glue down the top plate (it is already thicknessed) I mark all the way around the three sides of the head stock to the thickness I need, then watching the lines I just sand it to the mark with the belt sander. I have mine up on a shelve were it is easy to see the lines. Then I check with a caliper at many places and do any final sanding with 120 grit held on a block of wood. Glue the back piece on and there you go.

But I have to say, Terence's method is way better.

Terence, in the 2nd picture with the assembled parts that go against the long board that is angled, it looks like that assembly will rotate to keep it flush against the long board. Is that just something like sheet rock screws or wood screws or even bolt going thru the bottom piece of the assembly? That makes great sense.
Thanks for all suggestions. I've considered just putting the headstock on the belt and sanding down to a line marked all around. I'll mull all of this over and figure it out.
Much appreciated,
Bob

As I recall it's a 1/4" dowel Bob. You could also use a 1/4" metal dowel pin. One on each side. I took those pictures several years ago so I'll have to go look at it.

Ake,

That is a nice jig. I like the idea of putting the guides above the belt. (for me it would be above) Very nice
