Sanding LDD treated wood
Well I have tried LDD treatment for wood and I am finding that my
sandpaper clogs up immediatly. I think it was Lief that mentioned that the paper could be tapped on a hard surface and it would clean itself. I have not found that to be the case. Need help on sanding some spalted punky birch that has been treated with LDD. By the way that is Dishwashing Detergent not Automatic Dishwasher Detergent I hope. Rod |

LDD is for green wood, and not for "punky spalted"; or have I missed something? Bjarte |

Stiff nylon toothbrush in a pinch. You don't have to rush to sand while the surface is full of glycerol, you know. It'll evaporate in a couple of days. On wet stock - no LDD, just wet - I generally just run a sand at 120 or 150 after spinning out as much moisture as possible, reserving the 220 and 320 for when it's dry (er). They clog too badly, else. Just be careful not to overheat when it's getting dry. Yep, high-suds/humectant-added hand washing stuff is what he preaches. Madge is gone, but we still have Leif. |

He is he http://www.ronkent.com/RKhome.html It certainly does help with punky spalted wood BUT, be very careful. Do not leave the wood in the LDD too long. It should be only for a few minutes and when turned past the penetration level the LDD should be re-applied. If you leave it to soak you will not get any finish to stay on the wood as penetration can be 100% in just a few hours. Once the LDD is in the wood it can only be removed with a soak in water, then microwave, repeating cycle until no more foam appears. -- Remove no & spam to email meet me at: http://peterhyde.bravehost.com/ |

You just wait until I have completed all the operations, George! Ol' Madgie will be back in town!!*G* A side note about the topic, all the advice given is good. The thoroughly punked out wood that I have turned, didn't have any green wood portions, so I didn't bother with LDD. Some punky wood still has green areas and then I would use LDD. For really punky wood I used repeated dowsings of wood hardener. Seemed to work just fine! Definitely dishwashing soap (washing up soap for the more UK/Oz/NZ oriented?) Leif |

Sanding LDD treated wood
Thanks for the help. Too late smart and too soon oldt. Already soaked
the wood overnight I guess I was reading Liefs instructions and it seemed he was soaking all of the samples overnight and then turning them. Is there no finish that will adhere to this stuff. I was hoping for stabilization as I am making a lidded box as a test of the process. I am thinking that to resoak the wood will destabalize it again. Rod |

Sanding LDD treated wood
Hi Leif
Things are definitly working. Thanks for the tip on wood hrdener. I am confused as I thought the LDD had to soak into the wood to stabalize it and yet in Ron Kents article it appears that he just wipes it on and then turns the wood. You seem to soak it overnight. In any case does the LDD have to be compleatly removed in order for a finish to adhere to the work? I like to turn objects with a natural edge on them with the bark on. To do this I usually treat the bark with CA glue to ensure that it does not fall off somwhere down the line. Can I use LDD treatment for works like this. Rod |

What you're doing is the type of work _least_ likely to crack while drying. Interrupted-edge stuff is generally turned thin from the get-go and allowed to warp quietly. My experience says 3/8 or less has to be abused to get it to crack. I'd suggest opening the ears and flying without the feather here. Lots of wood has been dryed defect-free with no outside influence. Here's an example which should have cracked for certain with pith and all. http://photobucket.com/albums/d160/G...t=ff519f4b.jpg Reason it's a touch thick is that it was so punky and soggy it was moving too much to get an accurate gouge cut. That, and there was a guy inside looking at me. http://photobucket.com/albums/d160/G...t=e9b2539f.jpg Once your piece is dry, the only chemistry which might bother you would be the extra surfactant flattening a water-based finish. |
