i thought that was Einstein. He discovered E=mc^2 in the bath

Still don’t know if he got a reply do we?

Give em a bit ofo oiling, if in several months they are still discolouring then you can stain them

you’d be right, I’m trying to hand plane some slabs of Jarrah for a work bench top. It is by far the hardest thing I’ve tried to flatten. High angle plane sharpened to 16000 still struggles and tears out

Seems to saw ok though, if a bit slow

@TonyRio- Google Marri, Karri and Tuart trees. They are other natives of Western Australia, and could be what you have. All species can be found growing in the same area/forrest as Jarrah,and often hard to distinguish between species when live.

Thanks for the heads up! I’m getting some in two weeks and plan to route out quite a bit.

I just finished two Jarrah end grain chopping boards. A lot of sanding, cutting and routing to flatten. There was an enormous amount of dust. When I took off my disposable N95 mask, it left a white space on my face where the mask had been All dust is bad for you. Wood is also carcinagenic. I also wear a 3M dual respirator with charcoal and dust filters. At the end of the day, my white dust filters in the air intakes were coated with dark brown/red dust from the Jarrah. Trust me, invest now in some type of dust protection.

First of go back to your high school physics/chemistry days and look up how to find the density of most anything (including yourself.) the amount of that this wood or you displace in water is the density of that substance! A famous science story goes that Archimedes was ask to tell the king if the Golden crown that he was sold was real gold or a fake. Archimedes was taking a bath and the idea struck him that all he needed to is to place the golden crown in water when he saw the water rise as he entered the tub. He got so excited about about this –he jumped out of the tub and ran down the street naked shouting EUREKA!!!!! EUREKA!!!!! EUREKA!!!!! EUREKA!!!!! (translation I HAVE FOUND IT!!!~!). HE WEIGHED THE CROWN AND THEN PUT IT IN WATER—AND FOUND THAT IT WAS BRASS AND NOT GOLD.! THE SCAMMER WAS CAUGHT AND PUT TO DEATH FOR DEFRAUDING THE KING AS THE RESULT OF THIS DISCOVERY.

This is a very tough wood–are you sure it is Jarrah (Eucalyptus marginata) or related species.
While you may succeed for old wood you have a very difficult task in front of you. If this was fresly cut young wood that would be a different story.

I have used a lot of jarrah with no protection whatsoever and no problems.

Did you ever get a reply? I burn Jarrah offcuts and cut up lengths picked up from curb throw-outs during collections weekends. I find the smell pleasant, but make sure it gets a fast start-up with a strong flame and a good draw up the chimney and that the smoke is drawn away from you and pets. Also check that the timber has not soaked up liquids such as oil and only attempt tp burn dry timber.

Many thanks for the nformation. Regards
