Thanks for that! :-) Yeah, it's HDPE plastic with Aluminium angle for rails. We were meant to use power tools to make them, however my mate left them at his house...and the drive back was over an hour away...so we started with the hack saw.
They worked. The flex in the plastic, along with the softness of the aluminium caused the aluminium rails to crack at the bottom of the teeth - this occurred at the point of greatest flex, next to the aluminium cross bar. The cracks worked their way down to the right angle, but it was no biggy for me....they worked when needed.
I'm really not sure what I'd do next time...I vowed to never strap these heavy contraptions on to my pack again (they would now contribute to nearly two thirds of my overall base pack weight).
To me, MYOG snow shoes would have to be a passion - they are an item that is exposed to extreme forces, extreme conditions, and need to rate 10/10 for reliability and functionality, otherwise they would be dangerous and a wasted exercise. So, on that note, I probably wouldn't do it again due to the cost and time required to master this product.
