View Full Version : Need Advice - Turning "Punky" Wood

I'd like to get started turning peppermills, so I purchased a few spalted maple peppermill blanks. They all have "punky" places throughout, but the one I'm worried about is the most spalted - the prettiest one, of course - which obviously has the most rot.

What do you recommend to stabilize these blanks with? I'll have to make sure they are dry, which may make matters worse, but I don't have a pressure stabilizer and really don't want to spend a lot of money on the process.

Are they too big to use CA? would you soak them in a home-made or lacquer-based stabilizing medium?

Please throw all your ideas at me!:)

OK, since you said all ideas, my $0.02 would be to not turn it. I think it's just not worth it, punky wood looks bad, since it is punky. It won't buff to a shine. It sands easy, so your turning is not round. (you get flat spots) I've tried salvaging punky wood because it does look nice, but it's a lot of work and best be left alone.

That being said, CA fixes just about everything, and does work for fixing punky wood, BUT you can sometimes see the CA after you finish. It does stain maple.

I've used this clear penetrating epoxy sealer on some very punky spalted mango. The local Woodcraft store sells it here. It's fairly pricey, but not as bad as an equivalent amount of CA. It has very low viscosity so it really penetrates the wood, much like a thin CA.

System Three also makes and epoxy sealer, but I haven't used it so I can't recommend it, but here's a link.

Good luck.

Thank you, Kyle.

It's probably more work than it's worth. I guess the hardest part is to see an incredibly spalted piece go to waste.

Roger, I may try one of these. Were you able to achieve a decent finish after using it?

Remember Eric, nothing on the inside of a mill except bare wood. No CA, no Cactus juice, no PR...nothing. So...I'd make a cool weed pot or vessel from the punky stuff and get a more stable piece for a mill.

Eric, I guess that I am odd man out, I agree that it is somewhat a hassle compared to good wood but for me it is worth it. When I get it close to making the finishing cuts, I soak it with glue diluted 50% with water. Then I soak it with diluted lacquer sanding sealer when I start the sanding process. This is an example.

This bowl is approximately 4 x 11" and finished with two coats of pre-cat lacquer.

Very easy to use and it works very well in stabilizing punky blanks.

I mix sanding dust of the same species of wood and lacquer. I brush it into the soft spots and any tear out. Then I spin the piece to help rub the mixture into the wood. Acts like wood filler and blends right in.
