Thread: Glycerol Source

Can't help with your question, but interested in the rejuvenation process you're using. Any chance of starting a new thread on it please.

Darren,
We meet again... welcome to the forums. I am pretty sure I saw glycerol in a hobby shop in Fyshwick the other day. Not sure about quantities they sell in as I wasn't interested in it at the time. This hobby shop specialised in higher quality remote control equipment.

G'day Darren. Welcome to the best place to get information - I'm sure the answer you want will come.

You could try vetinary supplies or stock and feed agents.

Also known as glycerine - mail order from Melb

Hi Darren,

I too would be interested in learning more about your rejuvenation method.

You must be able to get it in big amounts cos My old work had a 25 litre container of it. Can't help you with where from tough.

Welcome tooooooo.

Is the reguvinating involving spraying the veneer with 10% glycerine/water mix then flatten under a weighted board? I did that with some very curly and crispy Huon veneer and it worked a treat.

Thanks for the link. Will give it ago. Here is a run down of the rejuvination process:

Mixture;

60ml of Glycerine
60ml of Metho
880ml of water

Makes a one litre spray bottle.

Spray the crusty curled veneers on both sides and let them sit for about 15 minutes. Then drain the excess liquid off the veneers.

The moist veneers need to be clamped between two boards or put into a vacuum press (thats the way I do it) to initially flatten them. Keep them pressed for about 30 minutes.

The flattened moist veneers then need to be lighly clamped between two boards and separated by corregated cardboard for at least a week but better if longer.

Put corregated cardboard on the bottom board, then a veneer, then cardboard then veneer and so on and finnish with cardboard and then the top board and lightly clamp so you dont crush the cardboard.

After 24 hours I take the veneers out and clamp them between the two boards to stop them buckling and dry the damp cardboard sheets in the sun and the repeat the claping process and then leave the veneers in the light press for at least two weeks.

When you go to use the veneers keep them flat under wieght until you are about to glue them as they will want to go back to their curled gnarly shape if allowed to.

Hope the above is understandable as I am not the best at describing a process with out the subject in front of me.

I use much the same recipe and process for new veneer that I' need to use straight away, but for veneer that I'm storing for future use, I also add some animal glue to the mix which keeps the veneers flat indefinitely. I also store flattened veneer in those plastic vacuum seal storage bags between sheets of ply.

Thanks for that info gents. Don't do a lot of veneering, but it's handy to know.
