some magnets to hold in place.

lots of small welds time consuming but no warpage! used wet rag to cool welds not shown.

Re: 1956 3100 build
 

I think they look better without them .

Re: 1956 3100 build
 

But your head will feel better with them :)

Re: 1956 3100 build
 

headrest come off easy so will trial it when up and running. here is my attempt at steering column cover and dash extension. credits to Ogre on this
forum for the details on his build page. winging it from there.

Re: 1956 3100 build
 

Question regarding the firewall panels. This may sound like a dumb question, but here it goes. How do you attach the top edge of the panel to the actual firewall? Is it welded, panel bond, or? If it's welded how do you carefully grind down the welds?

Re: 1956 3100 build
 

Hi Ricky i welded the panels on. small welds cool with with wet rag and repeat. no visable distortion. i used edge of mini grinder wheel for around edges. it was time consuming. will post pic shortly

Wow, thank you. Very nice job!!!

Re: 1956 3100 build
 

thanks Ricky. i talked to JML55 on this forum and he gave some pointers. i welded some holes from under dash. i found this link here as well that really helped.
https://www.hotrod.com/articles/1204...ng-a-firewall/
next job has been i flattened a piece of copper tube and used foil tape to stick it to under cab on floor to weld up all holes previous seats mounting holes . filled in all other holes not needed in floor as well.

Re: 1956 3100 build
 

that's improvising, sweet.
I have a C clamp that I cut the bottom leg off (so now it looks like a 1/2 c clamp) and screwed a magnet to that part. it sticks well to flat surfaces like a floor or firewall. then the adjustment part I use to screw down a copper plate over the hole I am trying to patch up. that way I can tack in a patch and then get rid of the magnet so the distortion and interference to the weld is gone for a nicer finished weld. it does stutter and spit because of the magnet but if you work alone and can't be under the truck and still weld on the inside.....at least the patch gets tacked in before the magnet goes away. I have thought about a C clamp with more offset. maybe build one if I get a minute.

Re: 1956 3100 build
 

hi raven is it just me or does trying to mig weld around magnets make for weird reaction? lots of spitting and sputtering like as if gas isnt turned on?

Re: 1956 3100 build
 

Yup, magnets distort the weld somehow. Not sure on the theory of it all. I usually just use them to tack and once the pieces are stuck together

Re: 1956 3100 build
 

Once the parts are stuck I remove the magnets and tack a few other spots, then grind off the crappy tacks.

Re: 1956 3100 build
 

its when tacking i notice it

Re: 1956 3100 build
 

I have noticed that before when tacking, so I Googled it.

Here you go


Do magnets affect welding?
When using magnets to hold parts for tack-welding, keep the magnets away (at least 6'' )from the spot you're welding. Magnets make a strong field that disrupts the arc. Welding close to a magnet can be very difficult or impossible.

Re: 1956 3100 build
 

Thanks Temptest. as they say google is your friend.

Re: 1956 3100 build

Re: 1956 3100 build
 

Question about your lower dash. How wide is it?

Re: 1956 3100 build
 

Hey 62barnfind lower dash is 4" props to Ogre for pics i followed his for my diy.

Re: 1956 3100 build
 

Coming in late on this thread but I'm impressed with everything you've done.

You're planning to make the dash extension using fiberglass? It looks like flat thin plywood strips and the bottom curve is a cut shipping tube. Is that about right? How did you bend the plywood to follow the curves of the dash at the ends? I wonder if table saw cuts half way through would be enough or not? Also wonder how the cut shipping tube will follow that bend?

EDIT: Just went back to post #56 and I see a separate piece of plywood curve at the ends. BUT... is the long straight piece held on in some way? I'm thinking a 1x1 or a piece of small angle iron screwed to the underside of the dash?

Re: 1956 3100 build
 

Hi Dan thanks for the encouragement.its goes without saying this site is a great source of ideas. onto the dash extension. it is 1/4" plywood for main length. the ends are glued on with PL premium. and a couple small nails. a couple hidden screws holding sides to body. mailing tube is used for curved on bottom. i just shaped regular cardboard for end corners. it is going to be mounted to bottom of dash with some old pieces of shelving channel.i went with 73-87 chev truck emergency brake pedal. as i would not have been able to put extension on drivers side with underdash pull handle .
