I'm back from a week in Brisbane and found this email in my e-box http://ubb.ubeaut.com.au/ubb/smile.gif so thought I would post it here, as I have no idea http://ubb.ubeaut.com.au/ubb/biggrin.gif
At our church in Lyneham, Canberra, we have recently had to remove a 125 year old elm tree, which posed a safety hazard because of progressive dieback. We have taken a 15-20 cm slab from the lower part of the trunk which is about 1.30 m in diameter. We want to preserve this slab and erect it on a suitable stand as a memorial to our church, which is about the same age. I have been asked to take charge of the project., but apart from having found out that the slab has to be sanded and soaked in polyethylene glycol for a number of months to replace the water in the cells and fibres, and thus prevent splitting, I have not been able to find any further practical information. Can anybody help us with an answer to questions like what concentration of PEG to use, where it is obtainable and its cost, and what to do at the end of the soaking period.

Lets see what responses we can get for him!
Cheers
