As the winter is coming, we're planning with my wife to build a simple, indoor climbing frame for our small children and ourselves.
We're also thinking of doing it ourselves as we can't afford to pay a lot for someone to do it for us. I'm not a wood working pro by any means, but I have and am reasonably comfortable with jigsaw, drill, sander, etc.
We've been doing some research and thinking, and I think we have a reasonable design which should be 1) easy to build, 2) low cost, 3) stable enough.
As context, our house is a timber frame building where all internal walls and ceilings are made of plasterboard, so anchoring is out of question, but we do plan to at least secure the frame to the walls.
Without further ado, here are our current sketches:
So the idea is to have 4 vertical poles in the 4 corners and 4 support beams in a rectangular shape on the top. The rope ladder and climbing net will be suspended from the top beams.
Since I don't think I'd be able to do some proper wood joints, I was searching around and found some three way metal connectors:
So the idea with these is that the beams would slot in, but the whole frame would be height adjustable as the pole bit has holes on both ends.
My first question would be, how are these called? I only found this US based site, but I'd like to buy them in the UK.
As for the timber, I was thinking of getting 75mm*75mm poles in 2.4m length, like these for example: http://www.ebay.co.uk/itm/3-x-3-75mm-Pressure-Treated-Timber-Wooden-Gate-Fence-Post-1-8m-2-4m-6ft-8ft-/151978589963?var=&hash=item2362a13f0b:m:mT27JK_Z9k8n_Z_wD0EmnTg
So the second questions is, would this construction be solid enough to hold a light adult (I'm ~70kg)?
Thanks in advance for any comments / help!
