Title: Sanding Question
Post by: simk on January 16, 2024, 05:22:49 AM
Hi there!

When sanding over different woods....how do you prevent smearing the softer white wood with the brown dust? Its somehow annoying but I'm sure you have the good recipe?

Thank you very much!

Sometimes when you sand edges that have carbon ply the tiny black dust gets in wood pores. I try to blow it out with compressed air. But not 100 percent effective

With all my woodworking I keep a damp cloth handy and wipe frequently... also raises the grain and males things smoother...

Like they said
DON'T use any paint thinners, oily wood color can transfer to the light color wood. I know :knothead:

You want to be careful using water as well, some dusts like Padauk dust practically turn into a dye when they’re mixed with water.

Thank you! I will try both methods! I love the bright white woods. They usually are very light too. Did anybody try poplar as a midlam?  :bigsmyl:

Paduke is really bad. I may be wrong but a wet cloth may make it worse.

I wouldn’t use a damp cloth or any type of thinner or acetone on bare wood myself. The best way to get rid of it is a fresh piece of 120 or 180 grit sand paper and a soft clean rag. Then use a sanding sealer like spray lacquer before sanding to 220. And never sand cross grain. Sand by hand the same direction of the wood grain.

.02 cents worth

Btw…. Use very light coats of lacquer on paduke… I’ve seen a heavy coats make That paduke bleed.

Try lightly scraping it with a cabinet scraper. That should remove the discoloration without affecting the bow itself.

even if I carefully try to sand with a fresh sdaning paper along the laminate direction the darker stuff spreads someinto the white lamination- its better but cannot completly avoid it. Never used paduke, but my reddish serviceberry makes a hell of a mess too every time I use it... good luck not all woods are that annoying.

excatly my strategie until now. softly scrape the discolored section clean - then only polish with steel wool. maybe not the perfect finish but clean. Thanks PatB!

once again it seems there ist not "the easy trick" for everything - some things obviously need a little cheating and nerves  :biglaugh:

What exactly is that white wood you are using? I've never had that problem with hard maple.
