Yes, we put our 35 IAE Stables up and I'll never do it again. We're just about to have another 20 put up (Loddon) and we're paying them to do so. You never get them up the way the professionals can.
You put all the metal frame work up first, doing each line of stables and not tightening it all up until everything is square. Then you tighten everything up and then slide all the boards in. We have plastic (amazing stuff) and you have to cut every last board (which has a nightmare). It was very very hard work!
Oh, wow. fantastic pictures! Impressive set-up. What I meant was, how do you fix the last board in? I need a custom tackroom set up and am considering using a local fabricator. IAE can't deliver til after Xmas now I couldn't give measurements til this week.
