Questions About Starting Strength Style C-Channel Power Rack
So I'm considering building a power rack similar to what Rip has at WFAC. Mainly because he made the plans available in the book, materials are cheap, and I can weld so I wouldn't be paying and labor or shipping. However, I have two reservations.
My main reservation is regarding the J-cups, or rather...the bolts. I can't really think of anything more annoying than having to go get a damned socket every time I want to change the hook position on the rack...and before you say anything about the safety pins acting as hooks...they only act as hooks OUTSIDE the rack. If I wanted to squat and bench outside the rack I wouldn't build a power rack...I'd just get some cheap squat stands.
Is anyone aware of j-cups that will work with a c channel rack like this? Does anyone have fab plans for a diy solution if they are not commercially available?
My second reservation has to do with the rigidity. Obviously Rip is of the opinion that these are extremely sturdy racks, more so than square tube racks. However, every time I see a video of someone lifting at WFAC, the racks are shaking all over the place like this: YouTube what's the story here? It seems like a rack that shakes all over the place (particularly if it's not bolted down as mine won't be) is less than ideal, even if it's not about to fall down. Have I just seen people lifting in a bad rack or two, or do they all do this? I've literally never seen a rack quake like that before.
