I live in the Acton Ontario area and am making a full size cello. The rib stock I bought from Lief needs to be reduced down to the usual 1.5 mm. Does anyone know where, within a commute of 1 hour or so, I could have rib sanding done accurately in a shop?

Thanks in advance

In general this work is done with a block plane and scrappers.

MANFIO is right. But I prefer to use more modern methods such as a sander. BTW, highly figured wood IMHO is better handled with a sander.

I'd call either Lief or Heinl in Toronto and ask who the cello makers are in your area...they should be able to help you... Good luck!

Try local furniture manufactures. I've worked at two in the past and both had thickness sanders.

Thanks Matt:

I found a place in Burlington "Exotic Woods" that will do it...

Best regards

Hi actonern,

Glad you found a place. We used to use a place in London (I don't think they are around any more) to do thickness sanding for fine furniture; it is my only experience with thickness sanders, but it worked like a dream.

My son bought one of these tools for thickness planing guitar parts. You are right-- they DO work like a dream. He also bought a dust-collector to keep it clean, and it is a marvellous combination.

The one my son has is made by "Jet" -- it seems to work well.

I have a Performax drum sander that works very well, it's too easy, has a 16" drum , open at one end, I think Delta may have a smaller one out now. You might be looking to spend 6-9 hundred for one maybe.
I also use it to sand joined tops and backs to the correct thickness, and to get the underside of the plate really flat, pretty easy to get it to a tenth of a mil. accuracy. It helps to thickness neck blocks after two edges have been squared too.
You will need dust collection of some kind, a shop vac will work ok.

In case you don't want to spend the money and have lots of time on your hands, there are many recipes out there for home-built thickness sanders, ranging in sophistication from the simplicity of attaching a drum to a motor, to designs which rival high end commercial ones for complexity and quality.

One source for ideas is the GAL publication Lutherie Tools. I built one out of 2 x 4s with a 4" drum made from plywood and particle board discs mounted on a cold-rolled steel mandrel and sanded to final shape against the platen, it's been working great for 10 years.

I used to have a Performax 16" open-ended one (you could sand a board up to 32" wide in two passes). It worked great the few times I used it but prefer to use handplanes for that type of work and sold it. I think Performax have a 10" bench top model. You will definately need a dust collector with it, I bought a 1HP model that worked well and I still use it with my bandsaw. The one Mat Roop posted it neat.
