Drum sanding

Timbuck · Apr 25, 2013

When I thickness the one piece Backs and Tops of sopranos on the Jet 10-20 I don't see the point in sanding wood that will be cut off later and end in the bin..So I profile the plates first then sand.
Here is another youtube (Watching Paint Dry Production Video) I made of Mrs Timbuck at work sanding.

I do them the same way. Is that what you thin your sopranos to? .075"?

Timbuck · Apr 25, 2013

Yes Chuck..back and sides .075" Top plate .0625" - .065".

But where is the special machine which cuts all 12 backs/tops to shape in a single pass? I can't believe that you don't have at least a jig for that!

I'm kind of amazed that you are able to thickness them on the 10-20 without having to use a carrier board. Gives me TAS

I'm drawn to the magnetic train wreck of allen wrenches stuck to the side of the sander. it gives a nice contrast.

I tape e'm all together 6 at a time with masking tape then mark out the top one on the pile with the template and then trim all six in one go on the bandsaw...I've not try'd 12 yet

The 10-20 plus goes down to 1mm from the conveyor with no problems.

How much more do you think you take off during final sanding? Do you hand sand them once assembled or use a sander?

Mrs Timbuck will sand them by hand a little before applying FP ..but nothing severe just a light once over with 200 grit to remove any marks...I find a rough flat CLA finish keys well into the first layer FP application on Mahogany.

Thanks. What grit are you using on the drum sander?

I use 80 G for most sanding..but occasionally use 60 G if I need to remove a lot of stock

I'm starting to believe that Ken just films and Mrs. Timbuck does all the real work.
