I haven’t read anything about anyone doing this, I don’t know if it’s a good idea…
Anyway, what I’m wondering is whether pre-tensioning cabinet panels would have any beneficial effect on stiffness.
This is where I got the idea, aluminium beam frames on motorcycles are welded under tension to give additional resistance to flex under stress. If for arguments sake, bracing inside a cabinet was very slightly too wide, say 1mm or 2mm too wide, thereby requiring the sides or back of the cabinet to be forced into place; the sides of the cabinet would be under tension so should have additional resistance to flex because of the tension shouldn’t they?
The sides could be secured using threaded bars which ran between the tops and bottoms of the stressed panels.
Bad idea? Daft? Possibly beneficial?
