I've got a friend who wants a more readily accessible roof from the deck, but can't afford to loose any of the deck space to a staircase. My idea is a permanently installed ladder that hinges out and attaches to a block(the bottom step) with some sort of quick disconnect. Much less production than a ladder ladder to put up, and with a short handrail and wider steps it will be more inviting for the average guests to climb up and see the view(for instance, we always watch the 4th of July fireworks from his roof, but a bunch of drunk people on a 10 ft ladder...
I've already built the upper metal "pool ladder" style handrails and incorporated 2 gate hinges into the mounting plate for the ladder to be added latter(now).
The problem I'm running into now is finalizing the ladder design. Not too heavy, but also needs to be really stable. Looking at the steps on the deck, I'd like to match this style(obviously at a different angle, stringers more like 70 degrees when folded out), but not sure if I'd need to add more to stiffen it up since the stringers will be ~10 ft long and won't be solidly built in like the staircase.
I believe the steps and decking are teak. I'm looking for any suggestions on what type of wood to use and if I need to add triangulation or maybe just a thin solid backing to stiffen it up.
My main worry is making it too cumbersome. How would you build something like this? 1x6 or 1x8 sides and runners? or 2xSomething on the sides? 1xSomething for the sides and a reinforcing piece that also acts as the mount for a short handrail? I'll figure out the bottom step details latter, need to finalize main idea now and gather materials for the weekend.
Thanks for any input.
