Unfortunately my mate broke the channel board today. He hit a hole in the snow and bounced onto the nose at speed. 100kg+ rider plus camping pack.
It delaminated the aluminium plate, back to the drawing board with that idea ;-)
He didnt even know it happened. He said he heard a noise immediately after the crash but it wasnt till we got to the car park that I spotted the damage.
I feared this would happen with this design and have scrapped the idea for now
It took a massive amount of stress to break it and under normal conditions it would never break IMO but Im glad it worked out how it did today as it saves me making more boards like that
Falls, nice article. I've toyed with AL and bonding tests over the last couple years with some minor success, but not enough where I felt ready to make a ski. Citric acid with abrading and VDS would be a good test.
Back in the day when I was a cook we avoided using aluminum pots when making tomato sauces as the acid would pit the AL if left in the pot overnight or for long periods of time. (or maybe I'm just a bad cook ;-) )
I have on my to-do list to conduct AL tests with home products that typically have acid in them (vinegar, vinegar/salt solution, soda...).
