Watch out for Nick Acton!!

I'm with Kris on this one. I noticed how the OP butchered the frame taking it apart also, but kept out of the thread, hoping a resolution was forthcoming. However, with a perfectly repairable chassis now ruined I am of the opinion you only have yourself to blame for most of this mess.
If you are a true scratch builder, you could have easily repaired the frame at the points you were concerned with and also repaired the bird cage if it required it. However, this would have required some real metal working skills, which I assume you don't possess, since you insisted on your path of cutting huge holes in the frame with a plasma cutter instead of cutting everything off flush, repositioning, and rewelding in proper placement. Probably a couple days work, max. IMHO, and I've actually done this, fabbed my birdcage, built my aluminum pieces, and modified my chassis where necessary. ( an original style chassis like yours)

I'm not really sure where the control arm mounting points were off by your pics, as the adjustment available in most of these will more than make up for any small differences in mounting. And adjustable control arms can be bought or manufactured by a decent metal worker/fabricator.

Continuing to post day after day to force a resolution to this problem is distasteful at best and embarrassing at worst.

Maybe you should consider changing your handle to something other than Scratchbuilder.

BTW, I've had great dealings with Nick over the 10 years or so that I've know him and I would trust him to build me a frame, car, or any other part if necessary any day of the week. That is, if I couldn't do it myself- which is why I'm a scratchbuilder.
