OS, I've got two 2x8s spanning between those 2 valleys to the left of the front door with a 2' wide plywood tacked onto them. It gives me a flat island to store things and do repetitive cuts.
Most of the time working on this steep is easier on the back, it's almost up in your face. But cutting the tile 2 1/2 inches from the center dictated where the saw had to be and the position of operating the saw. It was having the muscles in the back locked in place while cutting that did the damage. But it's not just age, the kid in his 20's that works for me felt it too. But it probably doesn't take him 20 steps to walk fully upright in the morning.>>>
I'm 46 still gettin up on steep ones workin on them,to be honest steep ones are easier on my back then 4-6/12's but people call me nuts all the time...so be it,i love it still :silly:>>>
As long as you are not in a hurry and get enough for it it is all good. I would set some scaffold along the bottom of the valleys to have something to stand on and to hold my materials.>>>
It's Darwinism, by the time you're 41 many of those "No Fear" guys aren't still around. Only the real cautious make it to 57.

I'm 55 and I will be finishing converting all the valleys from closed to open on this estate. It's 10/12 and taken about 10 days. I feel it in my lower back, but get limpered up with Ibupropin. I've had ropes everywhere needed, but it's a pain to make that many temporary safety tie downs.>>>
I'm 57 and I can tell you that concrete HURTS!. I do the same as you only less now-a-days!>>>
