Mix was off or moisture or epoxy went bad some hiw contaminants or somthin. Nope not to much hardner, I di...

Re: Well that did not work.
What do you mean? why didn't it hold or what happend? The epoxy just didnt hold, after it was cured I was able to peel the veneer apart like it was a sticky on a note pad. The epoxy was cured but in little round piece almost like sand. One of the test was one side of the veneer with fiber glass and...

Re: Well that did not work.
Ok, I've did some runs with a bamboo veneer and was all good. Used West epoxy, very strong bond. Which veneer did u use? Is moisture playing part with the QCM? Thx. The poplar veneer was dry, clean and I sanded it to rough it up a bit. The epoxy just didn't take. Next purchase of epoxy will be west...

Well that did not work.
After reading the Fiberless skis thread I decided I would give it a shot. I ordered some veneer, did a few test with QCM epoxy and some scraps. Come to find out it doesn't hold at all with veneer/veneer or veneer/base material. So I tried another test this time with fiberglass (so much for fiberless...

Eastern red cedar has a weight of 33 lbs/ft^3 and an elastic modulus of 6.07 GPa. So the modulus to weight ratio is 607 / 33 = 18.39 (I scaled the modulus up to get number that are easier to compare, actually it is 0,1839). Douglas fir has a weight of 30-33 lbs/ft^3 (average is 31.5) and an elastic...

look up the Janka hardness scale for red cedar, this will tell you how hard it is compared to other wood specie redcedar, eastern Janka Hardness: 900 lbf (4,000 N) Modulus of Rupture: 8,800 lbf/in2 (60.7 MPa) Elastic Modulus: 880,000 lbf/in2 (6.07 GPa) Seems ok to me, and comparing it to other wood...
