sorry for bing a wippersnaper here. I have seen this used. with a scaff wrench it is fairly easy, just mark out even steps on iy by grinding tiny bits out on all sides so you can adjust bits as per power rack.
wrt bar placment, i had seen had the bracket for resting the bar drilled/bolted on to the wall with spacer.
it was drilled/bolted into floor/wall and looked plent sturdt for the 400lb that was on there.
It was with steel not alli scaffolding.
I know that scaff can vary from country to country though,
It seemed to work well enough and you can nick if from a site or 2!
I thought they spoke English in England. What the hell did you just say?
Ahh man, I thought the exact same thing!! Here I was trying to visualize what he was saying and I lost him at the 5th word! [/quote]
Generally, a “spanner” is “English” for a Crescent (adjustable) wrench.
