Well made some headway today on the Grump......

I got the fender well headers off, drive shaft, and fuel lines... and then removed the motor and trans..

Image

Image

Then I got out outside hung it in the air with my tractor and pressure washed the frame and it's components.

Image

Image

Tomorrow I'm going to dress up some of the welds and make it look a bit more presentable.... :D :D

Well I ran square dimensional marks on the Grump frame today. I started with a straight bar just behind the steering box and measured from the center gauge hole in the front cross member and cross checked back from the upper arm mounts.

Image

From there I went back to a good marker on the rear frame rails which I chose a factory rivet head....

Image

Right side measures 77 .750 77 3/4 inch

Image

The left side measures 77 .375 77 3/8 inch

Image

That gives me .375 or 3/8 of an inch out of square now divide that in half if they are both out with each other even and that gives you .187 or 3/16 inch.
So that gives me enough to change the perimeter rails. I have some 2 X 5x 3/16 wall so there are a few changes I can make along the way. One get those ugly angle irons off and clean up the whole appearance of the frame. Also they ( previous builder ) went from 32 inches across the front from out side to out side of frame rail to 34 1/8 I guess for choice :D :D

Oh and I pulled the steering box I ordered a quicker manual one and pick it up in Carlisle tomorrow. I also ordered tubular upper and lower control arms with adjustable bushing for caster and urethane bushings, so it should handle better.... And look cool to .... :D :D

Well I got some tubing cut today, and removed the front clip of the frame.

Image

Image

Got my center line for my rear cross member marked.

Image

and did my pre-cut

Image

this way I don't have to work so hard to cut in my drive shaft loop after the rear cross member is installed..

Image

Image

Image

Image

and here's how I left it before I came down for some supper.

Image

Guess I'll head back up for a bit to get thing lined up for tomorrow..... :D :D

This part of the build cruises right along, and is the most fun part of the build. Today I'm hoping to get the rear clip fabricated, and maybe installed this weekend.
Last evening after dinner, I went back up and got the Front clip level and the perimeter lined up with the front, level and plumb, and tacked in place.

Image

After getting the centers lined up I cross measure to make sure I haven't created a diamond effect, and constantly checking my level side to side, front to back.

Image

Image

Off to the shop :D :D

Well made a bit more progress today, with the frame. I was going to fab a new back half and got looking and with some cleaning up the rear frame rails are in pretty nice shape. Most of the bad was in the center of the chassis and now that I have that taken care of I will just mate the rear half to my new cross member.
I started by cleaning up the rails were they would meet up with the new cross.

Image

This is about were they should go.

Image

Image

Well after removing the lower link bars I clamped some C channel to the bottom of the cross member to rest the rear frame rails on which would keep the guess work out of at least that part of the line up.
After which I tacked the frame rails in place and cross measures to make sure I was were I needed to be.
After tacking in place I removed the rear cross member were as I had no need for two of them with in ten inches of each other, and not to mention it was butt ugly. :D

Image

Image

Tomorrow I will install my drive shaft loop and start to secure more of the frame. :D :D

Just came down for lunch, after starting to tie in the front clip to the side rails.

After I welded inside the rails I was ready to close the outside, I'm using 10 gauge plate to join the clip to the rail.

Image

I'm going to give it a slight bend which will ad strength and save some room.
Looks like I will need about 50 degrees

Image

Image

After a slight bend.

Image

Image

Not quite enough the first time.

That looks as close as I need.

Image

Fast forward , trimmed and clamped in place and tacked.


Image

Image

Well done with lunch, so back at it. :D :D

It was a lot cooler today, but that didn't get the job done any faster. :character0029:
I finished up the front clip except for underneath. I can get that when I strip all the components off it and flip it up side down.

Image

Image

I also got the rear frame rails welded to the rear cross member.

Image

Image


Image

Tomorrow I'm hoping to get the drive shaft safety loop installed, and maybe fit the Grump back on to get a look at were I'm installing body mounts. Im sure not putting those angle iron mounts on. :D:D

Ok some updates on the Grump, I had less time in this week it just seemed the week flew by...... Well one of the things I needed to do was a simple task but just getting to it seemed impossible. But finally got it tacked in place was my safety loop.

Image

Image

Next I had to clean up a real mess from a previous builder on the front cross member were the motor mounts were installed.

Image

Image

After the clean up

Image

Image

Now I ordered my motor mounts today, but I'm fabricating the frame mounts. I can't put them in place till my motor mounts come in but I started the pieces.

Image

Image

Image

My new steering box and pitman arm came in and mounted up perfectly.

Image

My tubular arms came in today also.
