Ok here comes another update. I've been working on the 4 link the last few weeks and I've finally got it all together and bags one. I still have a few things to tidy up but I'm leaving for vacation Sunday and thought I'd do an update before I go. Here's the lowdown.
I built my notch out of 3x5 3/16" thick rectangular steel. Here are the first two pieces tacked up.
The top pieces had to angle in for me to be able to fit my bags between the frame and the tire. The 1/2 ton trucks have the bend in the frame from factory but my 1 ton is straight.
I ordered a 4 link kit from Welder Series and was super excited about it. Until it arrived and I saw how puny it was. Don't get me wrong. It's a nice piece and wil work great on my '51 when I get around to building it. But it's nowhere near big enough for this beast. I'm attempting to build the heaviest duty four link I can. Here you can see my new redesigned bag perch compared to the one I ordered from Welder Series.
And here's one of the frame mounts for the 4 link bars beside the kit version. I made the new ones from 1/4" plate and the bent piece in the middle are 3/8" thick.
Top pieces of the notch tacked up. It took forever to cut the angles in these. Notice the lip on the angled pieces. I didn't consider that turning in toward the center would make the rail wider when I first designed it. But I'm happy because it gave me a little bit more metal to weld too.
