I made a tool to squeeze the rivets using the guys from Iceland posted.
In Viking's example, they are doing GPW rivets. The MB rivets are not as easy to do because they are harder to get to. The frame is boxed in at the frame horns where a GPW is not. Anywho ....
I used a similar design but I had to make the throat bigger and the "C" clamp narrower in some areas so that it could get to all the rivets. This one has to reach 4" where Viking's reaches in 3" This one is not as strong, but I had no choice given the areas I had to reach.
This material is 1" thick but I added some reinforcement where I thought it might be week.
I used a 10 ton porta-power to do the squeezing:
I could not buy rivets that matched the head on my MB so I made some that look correct to me:
As you can see, the MB rivets are harder to get to than the GPW in Viking's video:
In fact, If you look at the above photo, you will see I had to cut some more out of the "C" clamp with a torch.
But ..... I think they turned out ok:
Not saying that they are correct, Just saying that they look like the other rivets in the frame:
A few blemishes but the rivets that were in the frame weren't perfect either.
Anywho, I'm not trying to fool anyone, They are what they are.
I did not post all of the failures but I did them similar to Viking's video. This was a two man operation. We heated them up till they glowed darn near yellow, Then guy 1 dropped the rivet in the hole while guy 2 quickly put the clamp into position. Guy one worked the pump. We had a couple bad ones but the more we did, the better we got and at the end, we had no problem with the process. Just have to be fast. I found that leaving 3/8" excess rivet gave me the look you see in my pics. As I said earlier, this "C" clamp is not as strong but I had no problem as long as we were fast. Once again .... spent all day on the jig and a couple hours installing rivets.
I need to make another anvil to do the flat rivets in the rear but now my confidence is high. Thanks to Viking27 and the guys who participated in the video and thread!
