Sanding

[camb]

After I have sanded the inside of a bowl I seem to have a build up of saw dust that doesn't want to come off. Can someone tell me what causes this and how to rectify it thanks Jeff

From everything I've read, I think denatured alcohol would help with that.

What are you using to remove it? Is it green (wet) wood? If it is sanding dust tends to stick a bit. I usually can remove all sanding dust with a paper towel with lathe running slowly. I use compressed air on hallow forms that I can't reach into easily. Sometimes I use DNA as Avi suggested above.

The wood is very dry ,I tried paper towels

I can only think of two things. Maybe what you are seeing isn't sanding dust but rather sanding scratches. This can happen easily when sanding bowls depending on the wood, quality of the sandpaper and also your technique. The other possibility is the wood has pores and the dust is getting in them. I that case compressed air or DNA can help.

Can you be more specific about what you are seeing?

Would like to see a picture of the wood & know what species we are talking about. If access to a air hose could also use air to blow out saw dust. Some folks use mineral spirits or water on a rag to wipe their bowls too.

It must be saw dust in the sanding marks thanks all Jeff

Since you are sanding the inside of a bowl, do you think you are feeling end grain that needs to be stiffened? It can feel like roughage sometimes. If it is end grain, try sanding with wax on the sand paper. This stiffens the endgrain and also minimizes loose sanding dust.
Actually, I use a mixture of mineral oil and clear beeswax.
Just a thought.............

I second that, Gordon. It really does cut down on the sanding dust. One of the guys at our local Woodcraft showed me that trick & gave me a little jar of his mixture.

Thank you , I have bees wax and mineral oil I will give it a shot. Jeff

Actually Edgar, I have to give credit to one of Carl Jacobson's videos for that tip. It really makes going back over endgrain with a gouge and light touch a quick solution.
