Thread: Milling boards from Jarrah beams. Worth it?

Looking at the pile you've probably got nothing to lose by trying. I'd look at the end grain carefully - the 210 face might be flat sawn maybe with some 1/4 visible the edges - so it might want to cup a little but 45-50mm is pretty thick so a pass through a thicknesser should fix that. Depending on what you're planning to do with the 45-50 boards you might consider cutting them along the 120 face to get more 1/4 sawn timber for more stability (although seasoned 45-50mm jarrah should be pretty stable) then glue up to width. Good luck - should be beautiful timber under there.

Cheers Charlie. If it doesn’t move too much the plan is the front door. I spose mill some, leave it for a bit. If stable front door, if it shifts too much use it for something else!

Anything to do with Jarrah is worth it.

If its a door you'll need to really minimise movement - stability is critical - so select as much of the 1/4 sawn timber as possible. There's a useful article in Fine Woodworking June 2012, issue #226 on building a lovely panelled front door. The door thickness in the article is 1 1/2 inches, about 38mm.
