Grumpy Grumman

Postby Pro Metal Shop » Sat May 26, 2012 7:38 pm

Here's my Grumman Kubvan project, it runs and drives the way it is now, however I'm swapping out the 454 for a fresh 402.

Image

Here's the 402 that I will be installing in the next month or so.

Image

Image

Image

I am hoping to get my new tires and rims mounted in the next week or so.

Image


I'll post as I progress on my project Grump, I've only been getting weekends on it but I may start working on it after shop hours.

Here's a look at the rear and how far inboard the shocks are.

Image

I'm figuring at the least I'm going to replace the frame rail's from the front sub-frame back. At that point I will relocate or even add some degree of angle to help reduce any roll motion in the rear. Even adding 12 to 18 degrees will reduce but all the sway. That and add a nice rear roll pan to cover most of the suspension.

Well a bit forward of my build but I know I'm going to need a new brake pedal so, I had one I built a few ago and it will work perfectly for the Grump....

I will build the swing mount when I tear it down for the winter ! ! Or sooner :D I have another big block I should be nesting on in , in the next few weeks along with a TCI turbo 400 trans and a 2800 stall converter that is a bit more street friendly. ;)

Hi Guys
I've been playing with the idea of fenders on my Grumman Kubvan to cover the tires a bit better. The back ones are flat and do the job, however, " there flat " so just an idea and it would work for all four corners.
I started with some 18 gage cold, and put a 3/4 inch 60 degree bend on one edge and ran it threw the stretcher to get a radii for the wheel opening.

Image

Image

Then trial fit....

Image

Image

Now that it fits the opening I need to to shrink the outer edge to give it a sort of bike fender shape.

Image

Here's a look at the shrinking dies I used called thumb nail dies.....

You can see the compound in the fender starting

Image

Image

I premarked some lines to follow when the fender was still some what square, so I could track straight.

Now that I've shrunk the outer edge I am trimming in a bit to get a bit close to my crown with the shrink.

Image

Image

Here it is cut to about the size I want to end up with.

Image

Now I need to get a real strong shrink and isolate it to a particular area, so I am going to tuck shrink with my tines.

Image

Image

Here's a nice tuck formed.

Image

Here I tapped the edge with my door edge hammer to lock the tuck so it doesn't try to open as a trying to crush it in to it's self.

Image

This is the direction I will hammer to drive the metal into itself.

Image

Image

Ok some fast forward some wheeling and cleaning up the first outer edge I gave it a trial fit and here's what we got.

Beautiful workmanship. But why not aluminum?

Thank you Pop, that is just my test panel and I'm going to be using 3003 H14 aluminum when comes time to build all four. This one will give me a pattern to go by that I will be able to reveres from left to right. :D

Well I started to unbolt the body from the chassis yesterday, hoping to get up to the shop and get more done. I'm doing this so I can swap my motor and trans and give a ( look see ) on what else I need to clean up, replace, or repair, while I have the body off..... I will post some pictures later for updates. :D :mrgreen:

Hi Guys
Well got the body off today, took be about an hour longer then expected, but I also mocked up a whale tail on Kates Mustang GT :D :D

Image

Had to mark some wires so even if I replace them I know were they are going..

Image

Image

everything worked but just not organized, so it will take time to get it cleaned up and put were or replaced with new.

Well its coming up so far nothing hanging up......

Image

and she's free :D :D
