Thin Back

My Sanding Machine which I made 35 years ago finally Manfunctioned and took a nice piece of Indian Rosewood that I was going to use for a Dreadnaught Back down to 1.5mm. I don't feel happy about using it as I have never taken a back down to this thickness before. Has anyone used this thickness on a Steel string or a Flamenco Guitar before. I would welcome any opinions before I junk it. Harry.

you could make a laminated back with it, ! in a veneer press
My thinnest back was 1.8mm for a flamenca negra .. works well.

Thanks Stephen for the reply. I think I will cut my losses and not use it. I figured out what went wrong with my sander. Two bolts came loose and allowed the feed frame to vibrate up and down. Teach me to not take everything for granted even after al these years. Thanks again, Harry.

Why did you use 1.8mm, any particular reason? Because it was a negra?
Do you think it would make much difference if it was around 2mm?

Why junk it?
Why not use it and see what happens?
My guess it will make a very loud (and light)guitar

Could be really interesting to find out and rosewood is expensive so its a shame not to give it a try.

I would use it.

I think I'd modify the back braces slightly to compensate, and I would make my tentallones perhaps a bit bigger (thicker) for a stronger back-to-side join ....

I think you'd probably be fine. Just have to be a bit more careful...

"Thin" can mean a wide range.

Romanillos says that Torres sides were almost always 1mm. Yah, I know - but his book clearly says 1mm!

RE: Thin Back (in reply to Ramón)

thicker linings would have no benefit nor would heavier braces. After all the back is thinner therefore it requires less bracing to hold it in place. Before considering whether to use it I'd want to know how coarse the sandpaper was on the sander. If it was really coarse there would be little latitude for finish sanding or taking out blemishes.

RE: Thin Back (in reply to AndrewE)

I used 1.8 as the rosewood was very stiff, for a negra, if you use cypress then 2mm to 2.2 would be good, so... rosewood is heavier and more rigid..

I once (long time ago!) used a HUGE sanding machine industrial one with double rollers, to sand some rio sets I was going to use... set up the machine and put the timber through for a test pass... and . it didnt come out the other end!! sanded it to oblivion!! wooops. good job noone was looking, think I buggered up the machine. It was used for doors etc you know, 3 inch plus or minus a few feet!
