Jarrah thickness
Hi, I have some old Jarrah timber from a pergola which I am looking to turn into a drinks cabinet. What is the minimum thickness I should resaw the timber to? I am trying to reduce weight but maintain the stability of the wood.
Thanks

I'd say about 20 mm. By the time its dressed it could be around 16 mm? Should still be OK.
It depends on your design but to save weight you could also go for a mix of thin and thicker boards, say 12 and 20 mm dressed.

Depending on how good you are at resawing accurately, i'd resaw 2-5mm thicker than what you're planning on using in your final project. Then let it climatise for as long as it takes for it to stablise. Use a moisture reader if you have one otherwise let it sit for a month or so after you've resawed it. Dress it all round and you should have a reasonably stable piece of timber, I always like to let it sit for a day or so after this step to allow it to climatise before cutting any joinery.
In terms of your final thickness for your project thats entirely up to the look you're after, as BobL says i also like to hover around the 12-16mm mark for the case itself.

I would want the case to be around 18-20mm thick, with the latter more desirable. 16mm is too thin, unless this is a box. Aim for 24mm thick re-sawn sides.

Agree with the previous post for some weight for stability.
