Hello,

Ok, the frame is ready for blasting , just have to remove a few bolts and engine mounts.
Interestingly, when removing the rubber axle bumper, all bolts were good, and F marked, but 1 was a odd ball with an offset strike.
The wrench didn't hold, so I used a vise grip to hold it.

I will place it back into position the same way, when I install the new F marked GPW rubber bumper blocks . They are perfect reproductions and I am looking forward to their arrival .


Now,
I do not like blasting, so I called a place in a nearby town that does it.
They will blast the frame for $100 and hour. They said it usually takes 1 to 3 hours for a car frame.
This frame should be a little easier.
Great !!
However, they won't blast the body as they said their blast pressure is too high and could warp thin steel.

Ok, well I will drop off the frame, and blast the body myself.
Just have to get some parts for my blaster and more media.

I got all the spring hangers repaired, and ground back, and the bolt holes filed so a new bolt fits in tight.

Now this brings me to the GPW springs adventure !!
They are going to the blasters as well .
The Ford springs that I got to replace the existing ones look good.
However, they do have an issue !
On the 2 rear springs,
2 spring clips on each spring are loose, the other 2 are factory perfect.
How this happened, I have no idea !
I haven't seen it on any other jeep.

The GPW clips are riveted onto a particular spring.
The clip holes are wallowed a little, but the rivet is solidly attached to the underlying spring.
My question is what can I do to repair this issue ?
I don't have any rivet tools yet, but I will have to invest in some ๐Ÿ˜ƒ
I am wondering after they are blasted clean, if I heat up the existing "stretched out " rivets, I can re rivet them back down tight ?

If not, I will have to figure out where to get new rivets, and a way to attach new spring clips.
I have a full set of nos GPW spring clips from Ron.
But no rivets yet.

Here are some pictures of the springs :

Bazza, do you have any ideas here??
๐Ÿ˜๐Ÿ˜๐Ÿ˜


I will post the spring repair question in the technical knowledge section as well.
I searched for a similar repair and found nothing, but I am sure someone has done this clip repair before.

I plan to take these springs apart, and replace the center bolt in each spring with an NOS bolt.

I can clean and restore each spring, as they need attention.

The 2 front springs, and the TRS are in excellent condition !


UPDATE :
G member Bowman provided what we all need !!! Thanks !!

The definitive answer of what size rivet is used to attach the Ford GPW spring clips:

1/4 x 9/16 round head rivet !!

This is great !!!

You can still buy new clips genuine ford NOS . There are several different ones though due to the number of spring leaves . The special bolts are just now available from JMP (F stamped) The rivets can be bought off ebay - nothing special about them. You will need to heat up the rivet in a fire and hammer it into place . Alternatively put the rivet in cold heat the end up with OXY Acetylene and hammer. Don't warm the spring leaves up.
I have done mine and you should find other posts under GPW springs. I think we have spoken about this before ?

good luck

Hello Barrie ,

Thanks for the information !!
JMP is really helping us all out !!
I don't remember talking about the rivet repair but certainly possible, it has been a long time ๐Ÿ˜๐Ÿ˜

Is there any particular type or size rivet I should be searching for ?

I assume the the lower side of the rivet needs to be flat ?
Do I use a regular rivet, then grind it flat, to fit between the springs ??

I see several steel rivet options on ebay, I will measure what I have to see if I can get ones close to what I need.

I would like to learn how to do it, and have the torches.
I need to get an air hammer with a rivet tool to attach.

Especially since I also need to rivet in the rear seat brackets on the GPW body .
The brackets were yanked out by Bubba some time ago.

The rivets for the spring and the seat bracket look to be about the same size.

Best Regards,
Ray

Just have a practice Ray - find some old metal drill some holes and have a go - I can't remember what size the rivets are maybe 5/16" - buy some you can cut off to length a Dome head hot rivet .If you were doing a frame or chassis the air tool will help a lot but if its just the springs and you can get help with it a hammer is all you need (plus an anvil or old engine block to place the work on).

Hello,

Thanks Barrie,

I will give it a try, and will measure the rivet head for the size.

I will order some off ebay today, and also a cupped air hammer shaft.

It should be a fun learning effort !
You have inspired me to go for it !!

If it works, I will repair also the existing GPW springs that were on the frame, but had Willys type replacement clips added to it after the Ford ones were removed.


Thanks !!

Best Regards,
Ray

Hello Barrie,

Update:

The correct rivet to attach the GPW spring clips to the leaf spring is
1/4 inch by 9/16 of an inch, round head steel rivets.
Thanks to Bowman for posting this Ford document !

Outstanding !!!!!

Hello,

I took the last few things off the frame to get it ready to be dropped off for blasting.

Here is one more part that I got cleaned up , primed and painted.
I always like to see paint going on ๐Ÿ˜๐Ÿ˜
The brace for the master cylinder area. A nice circled F mark.

I am thinking that I will add some bolts to threaded frame holes, and also a few washers and bolts in the spring bushings that appear to be in good shape still, to protect them from the blasting.
Evidently the place uses high pressure, so I don't want to damage any threads or bushings while being blasted.

Best Regards,
Ray

Hello,

Ok, so instead of sending my frame out to get blasted, approx $300 ?
I was offered 2 pallets of glass bead media, about 84, 50 pound bags, for $8 a bag.
So I bought all that, and will get a blasting attachment for my power washer and try this method.
Plus I can recycle the media from the driveway when dry, and reuse.

Now with the new parts for my vacuum blaster, I also bought 2 bags of medium glass bead media. That cost $75 a bag !!
Uggh !!
But free shipping ๐Ÿ˜

So I will now be able to do all my blasting without the dust issue, with wet blasting , and less dust with the repaired vacuum blaster.


Some great new frame bumpers have arrived.
These are F marked, rubber axle bumpers.
These are perfect reproduction items !!!
Very nice, not that anyone sees them, but it is just nice knowing they are correct and high quality !!
Resized_20211122_101624(1).jpeg
Resized_20211122_101626(1).jpeg
These are just beautiful !!!

Just starting to drizzle , so a little rain on them .

For comparison to a particular original one on my 43 :

Resized_20211122_110914.jpeg
Resized_20211122_110902.jpeg
The only differences are, that the new one has a 38 on it, the one I have has a 42.
The F in the 38 one is also in a slightly different center point.
There must have been many subtle differences between many batches of the bumpers from the factory .
๐Ÿ˜ƒ๐Ÿ˜ƒ๐Ÿ˜ƒ๐Ÿ˜ƒ
These are so good !!

Another update:
Looking at the other original bumper on this jeep, yet another variation in markings !
This one has the gpw and numbers located in a totally different orientation and also has a 47 on it.

Hmm.... ๐Ÿค”๐Ÿค”๐Ÿค”

Those frame bumpers look great Ray. Are they JMP too?

Hello Dave,

I don't think they are JMP.
They came in clear plastic bags, with no labeling.
I looked at JMP ones Ron has on the site, but they didn't have the markings on the rubber.
At least the ones pictured didn't have any.
I got these from another supplier .

I get most of my parts from Ron, unless he is out of stock.
Hopefully parts will start coming in soon, as I have to get an F script gas tank from Ron.

Best Regards,
Ray

Hello Dave,

A quick question for you ?
You gave me the rivet size for the GPW spring clips, which is outstanding !!!
Thanks so much for that!!

Would you possibly have the rivet size for the rear seat brackets that are riveted to the sides of the wheel wells on the Ford built GPW bodies ?

Mine were torn out, but I will rivet new brackets in once I get the rivet size.

Hopefully they are the same as the leaf spring clips.

Ray

Hello,

Happy Thanksgiving to everyone !!

I got this nice WW2 ax for the Jeep.
It ismade by Warren and has USA stamped on it.
The ax handle has olive drab paint remnants on it as well as the ax head. Some previous owner cleaned the paint off the handle.
I was happy to get this rare ax.
Warren was a supplier of this ax during WW2.
Most WW2 axes are getting harder to find, along with shovels.
But I keep looking, and that is half the fun.

I will clean and repaint this ax to mount on the Jeep !

This is a strange one Ray. The rear seat support GPW-1162400 isn't mentioned at all in the GPW March 1943 parts list. No mention of the rivet to use either. The rear seat pivot bracket is listed, together with it's 1/4 x 3/8 round head rivets. That ties in nicely with the 0.26" punched holes shown in the blueprints for the pivot bracket.

However, the blueprint specifies 3 x 0.28" punched holes for your rear seat support bracket - 0.02" larger holes than the pivot bracket. I can't find any rivets listed that would suit a 0.28" hole, other than another 1/4" rivet above.

The 1/4" rivet is 0.01" smaller than the punched hole on the blueprint.
So in the same way, a 0.28" hole might be expected to take a 0.27" rivet. That would make it a 17/64" maybe but that size isn't listed in the parts manual!

It's possible that a later GPW manual will include the correction. Sorry can't be more help.
