Firstly I have heard rosewood is considerably stable, I have a room 8 meters wide which the boards will span across (not the lenghthways the boards are running). I have read I will need an expansion joint if over 6 metres. is there anyway of avioding this? is PNG Rosewood stable enough to just leave 10mm either side. no need mid floor joints other option is to leave 1.5mm gap every 1mt

If I decide to go ahead with this will I need to machine toung and groves in my boards? is it possible to butt join them? or will this be to unevan? biscuits? it is a lot of machining to machine 65m squared flooring Toung and grove from rough boards. should I perhaps buy premachined boards? boards need to be T&G, biscuits are not a good option. boards should be machined by a professional setup, its also a good idea to have them end matched to have less waste.

should I lay 140 x 12 mm boards or 110 mm x 12? I got a price for 150x50 or 120x50 for $2600 +GST a cube. lenghts of 1.8 to 3.6m. is this price ok? if you deep cut the 50mm down to 25mm this will cause problems with the boards unless they are re seasoned, you need the flooring to be kiln dired,

Thanks for reading, I will appreciate any advise on this subject.

cheers.

ok thanks gaza for your prompt responce.

With leaving 1.5mm gaps each metre, would it be possible to leave say .2mm gaps between each board using thin packers? or would this look wrong?

I was thinking I could deep cut the 50mm board 3x by bansaw. could this be done and sticked to airdry then planed then put through the thicknesser after a period of time?

also, how do you mean end match the boards to save material?

open to any other advice.

thanks.

step #1 : Make sure the floor is dead dry!

step #2:Gaza is on the money, read what he says and go to the reno forum.
