Hi All

Any one got any tips for removing ebony dust from spruce ?

I have had the top sealed all through production, but when I took off the seal coat, I've got some dust in the grain of the spruce which is being stubbon.

Many Thanks

Russell

I've had some success with a rubber eraser on maple bindings.

Thanks Tim

I tried Mathalyted spirit, as I have never been able to find Naptha over here.

I also tried White Spirit and this has got most of it out.

Look for Zippo lighter fluid (same stuff as Naptha).

Zippo fluid is naptha?? I never knew that. I have a huge bottle of zippo fluid

I always thought it wouldn't evaporate entirely.. it seems to have that oily residue.. Im gonna test it on a set of maple right now

Just read the bottle...

Contents : Naptha..

Good tip Tim ;)Jason38606.8435300926

Thank you for that, I didn't know that either, I can get hold of Zippo fluid easily.

Many Thanks

Russell,

I'll pass along a tip I learned from Bill Cumpiano that may help you. If you are sanding with a grit finer than 220, go back to 220 and see if that doesn't help. Cumpiano claims -- and I have no reason to doubt him -- that the size of the dust particles created by grits finer than 220 can lodge in a wood like spruce's grain structure, causing this discoloration effect. If one does not use sandpaper any finer than 220 grit, the dust particles are too large to penetrate.

I've tried this, and it really does seem to work. Even though I'm often tempted to hit the wood with 320 before calling it quits, I make sure that, if I do, I stay well away from any woods that might discolor the spruce.

Best,

Michael

Hi Russell,

I also had problems finding Naptha over here, turns out that we don't call it Naptha, we call it Shellite.

Your lot call it Coleman Fuel.

Here's a link to a table of International Fuel Names for any one else with the same problem
