Thread: weather woes

I think you have answered your own question. It would appear the panels are backsawn, which means they are more suseptable to climatic variations. As stickering and weights solves the problem over night, it is fair to assume conditions during the day are less than ideal. If you do a moisture check on the timber it will probably read very low. If climate conditions remain humid the material will eventualy come into sinc. Only problem is, when the air dries out it will start moving again. Why not leave an offcut out and monitor it? When it settles, attack the job again. In the meantime, sticker out the work pieces. Remember, thin backsawn timber is always going to be prone to cupping.

Things to be aware of are, rapid changes in temp and humidity, pretty obvious hey!
So, when you are doing a job that requires uniformity you must employ tactics that ensure minimal changes to the temp and humidity.
Believe it or not the answer is all around you, being sarking, simply wrap your work in sarking, silver side out, till the next time you need to carry on with the job and you will find the product slows down the temp and humidity rise and fall dramatically, try it on a piece of scrap, put it in the boiling sun under sarking and you will find the enclosed item, cool.

Oddjob1 use the stuff that is non porous.

Thanks for the responses.
I may have been a little quick off the mark as the timber seems to be settling down quite well now with just tiny movements which i can work with.
