Re: [DML] Re: New composite underbody

["Martin Gutkowski" <martin@xxxxxxxxxxxxxx>]

I was referring to your frame extension modification as heath-robinson, not Ed's brackets which are a professionally produced product.

However in *my* professional opinion, the design is flawed. If you're going to make the LCA's act as wishbones, make them wishbones. Eliminate all fore/aft movement including that generated by the ARB. Simples.

I have a concept in my head, I have started come CAD models but I'm too busy making a living to spend much time on it at present

Heath Robinson, eh? Pretty hypocritical from a man who is working on replacement LCA's himself. 

Just so everyone is clear: all LCA's other than Martin's yet to be seen design are unacceptable.

Re: Byrnes LCA's: He did indeed "hand the job to a third party who knows what they're doing" (two actually: a structural engineering firm and a metallurgist). To be brutally honest, Byrne did more pre-release engineering than Bryan Pearce did on his arms. The design has been in use for more than a decade with no reported problems, so it is certainly service tested (far more extensively than the cheap folded up 16 gauge LCA's original to the car).

Don't know how Ed handled bracket engineering. Since they are sold by DMC franchises I have to assume they have Houston's blessing. They are pretty innocuous pieces of hardware, so I continue to be mesmerized by the controversy they stir.
