Yep, I must admit .... My filler rod hand isn't as steady as it once was

Mind you .... Still not bad for a doddery old fart like me

I was TIG welding some stainless steel boat parts the other day at work &was so relaxed that i must have fallen asleep & started dreaming or something but when i snaped out of it i was still welding & the weld looked pretty good too thank god i wasnt MIGing I would have made a good mess but then again i dont think i would have falen asleep MIG welding.

Hah i just got my city & guilds in tig welding on monday. happy days! oh seeing as we are talking about welding and chassis..... rather than starting a new thread just want to ask a quick question on this idea.

Pic is not my chassis its a pic from Gingae1pom's build! but anyhow I really really really dont like that blue bar when i do my build i would like to remove the blue but add all the red... also using a roll bar design the same that will be also inplace of that bar. It will still be there just not any bits that extend past the plate....

what do you think? oh yeah yellow is plates! its kinda like the Donkervoort chassis shown here..

Whats wrong with the blue bar? Its covered in aluminium anyway. I can't see there being a massive problem, but imagine that blue bar helps loads in flex as the suspension loads up that turret.

I mean on every sporty production car, everyone puts a strut brace between the turrets to help the road holding.

Could not agree more. The red bits will not add any significant stiffness, just weight.

Well, usually strut bars link the upper suspension mount points. In Haynes the suspension mounts are well boxed anyway. Maybe the complete seat back box improves the torsional rigidity of the frame, but anyway it's just guesses, changes like that should be tested with FEA, like the book chassis was tested.

On the topic of TIG welding. We are a company that produce components for kit cars and chassis and we always TIG weld. Its just our policy to always TIG weld due to all the reasons people have mentioned above.
