My FIL makes bamboo ladders from scratch for people who order them. He does about one a month and makes them very long and seems to be well known on his quality. Today I helped him go track down and cut some bamboo and bring it back. There is a whole lengthy process to these deals if you want ones that you can climb up with confidence. Personally I will not use them, even the one my FIL makes. I have climbed up a few and I prefer my Little Giant multi purpose aluminum ladder that I brought over from the States. I like versatility and alumimun just feels far safer. The Bamboo ladders are a fixed height.
Here are few pics from the start
After bringing back the bamboo my FIL starts a fire and does what he calls heat treating the Bamboo. My Lab watches with careful eyes in the background
Starting the process of "Heat treating"
This will be a very long ladder. A guy came and ordered it yesterday. It takes 3 or so days to make one.
I will add more pictures of the process as I have time.
