The idea that you "deserve" an answer in this context is problematic. You can ask a question and express a feeling if you don't get an answer you like, but you're not entitled to an answer.
They're printing those houses here in Detroit too, but using concrete for climbing devices wouldn't work. It seems to make a big difference what the thing being printed needs to be made from.
As I said, for better or worse, although which side you see is colored by experience with this particular device or the absence of that. I'm assuming you climbed on your own device prior to it receiving any sort of certification. There is some amount of practical understanding of risk and...
One thing I can say is that Gordon's devices are constantly being refined and upgraded based purely on real world feedback over many years of use by many working arborists in different locations and with different climbing styles. For better or worse, he is not beholden to meeting certification...
I'm going to be listing a Unicender for sale shortly here, $200 shipped in the states. You could buy it, try it, and resell it if you don't like it at that price.
I think a good method, especially for the smaller chains, is to use the combo file for every other or every third sharpening. Just do a round file by hand in between because I agree that the combo takes off too much raker.
I'm interested in the SMC pulley, Courant throw cube, all the slings and biners, the wedges, the Notch chainsaw lanyard, and the Hoffman boots. PM me a total with shipping if you would and we'll go from there!
Just want to sing Arbsession's praises again. I reached out to see about getting a replacement ratchet buckle and some screws for the Spikepod gaff strap set I bought and Casey contacted the manufacturer right away. They opted to send me a whole new set because the style had changed at no cost...
I think the idea that someone who would choose Arborplex as a climb line is also keen to buy the latest and greatest mechanical is a bit strange and not in keeping with reality, but I'm sure they've ran the numbers like good capitalists.
Glad it wasn't worse and you're telling the story with an unbroken body. We don't have Raywood Ash in our neck of the woods. Anyone know of a Midwest equivalent for reference, in terms of characteristics?
