I�m in the process of making a transmission tunnel (as the person I have asked is taking ages to do it and I�m pretty close to doing it myself)
Just wondering what�s the difference and what is preferred, Cold rolled or Hot rolled sheet metal.
I�m thinking of using 1.6mm-2mm thickness, I�m thinking 2mm may be too thick??
Thanks
Bart

Thanks FastEH
I have already cut out the tunnel and bought cold rolled sheet metal, should arrive Tue so I will be withdrawing for a few days for not doing any work on the Torri
The RB25T Nissan box is pretty tall and fat so your tunnel my not be the go.
Thanks anyway, good luck with the sale on fleebay

[Bart]

as suggested already cold rolled is best 1.15 or .95 is the best (and closest to original thickness) i have found but depends on what shapes your trying to create.2mm will be to thick imo
good luck look forward to some pics.

Interesting, my tunnel is about 1.8mm thick.
I want to stay with that roughly

[Bart]

1.8 mmm not having measured mine ill have to take your word for it but most of my other panels are about 1 to 1.2mm i wonder if they made the floors thicker than exterior panels?

Yes I would say so.
I believe exterior panels are thinner. I had safety in mind so i went 2mm, dont want a fly wheel in my foot. The motor im using is capable of revving over 8000rpm. You just never know.

The tunnel in my LX varies from about 1.0 mm to 1.5 mm presumably depending on how much the metal has been stretched or shrunk and how cleanly I cut the holes.

ls2lxhatch - sounds like a good prognosis

bart - looks like fun 2mm will be a bartard to shape

Yeah it will be but fortunately there wont be too much shaping to do. It�s not too multi dimensional

[Bart]

Still early days, looks a little too angular, but then i probably shouldnt worry too much about asthetics since its just a tunnel.

[Bart]

This is my home made folder originally made to fold aluminium, to my surprise it folded 2mm cold rolled steel.




Tunnel progress, i have tappered the back end of the tunnel a little more.

looking good bart...top job

[Bart]

Time to fully weld it in today.

[Bart]

Fully welded
Real prick to get my head in there, welded a little blind near the fire wall but got there at the end.

Love your shed mate. Looks like mine
Better than some of the gurly sheds you see
AND.. I have bent sheets with a bender just like that

[Heath]

LOL I could not work in a shed like that, but clearly Bart can. That looks sensational! Very simple in its form (which I'm sure made it much easier to shape) but it just looks perfect. No excessively large dimensions... looks like there is still a fair bit of room left in the footwell for your feet to operate in etc. Tops!

Thanks mate its a little crowded in there but does the job, occasionally trip over shit lol
I have plans on building a 8m X 5m out back maybe a little bigger, have to see what the bloody council allows, damn Nazi's

Yeah I know what you mean, as mentioned its a little crowded, but builing something bigger in the future. The damn Pontiac takes a lot of space.

Had a bit of an accident today, while welding the outside of the tunnel with an oxy (as its much nicer weld) the inside of the car caught on fire, to be exact the damn plastic lower heater duckting which is right near the tunnel/fire wall. Got the extiguisher out but screwed the duckting and a coupl of wires. Not happy but could have been worse i guess. Sometimes it feels like im just digging a bigger hole for myself. ut my passion for cars and my Torana keeps me going.
