Ive got another fiesta Si (mk3) that im making in to na 2.0 track car. Ive heard about seam welding to strengthen the chassis. Sounds like a good idea but i dont know where to start. What exactly would i be welding???


cheers

 

Strip off all the soundsproof/sealant....front front to back identify all the points where the chassis fixes to the body (usually a 'U' section chassis spot welded to the body) and work down each (seam) stiching (welding)the lip of the chassis to the body...differing opinions onthe next part...weld the two together leave a gap then weld again down each seam....we usually weld approx 25mm leave approx 50mm....mark it up before you start to make it uniform...

CHeers mate think i understand that. Dont spose you have any pics i can look at.

Thanks

 

Heres a pic of my car during the process....

 

thats the way im doing it on my nova as well.
i got told to leave gaps to stop distortion

 

Take it to Dave Colledge at Retro Ford (www.retro-ford.co.uk), get him to sort your cage too.....

It might cost a bit..... but grown men will either cum or cry when they see the cage etc.....

 

im going to be doint it myself with a couple of mates. Its jsut a cheap project really dont wanna spend loads of wedge. Just doing it to learn some new stuff really

 

i would use shorter stiches as not to put too much heat in and distort the metal work, obviously leave shorter gaps to tho.

good luck matey!
