I am a long ways from ever mounting this cab to the frame but I figured while I was channeling the truck I should figure out how I was going to mount the cab to the new frame. The old cab had six mounting points that I could see. A and B pillars and near the fire wall, but when I channeled the cab I cut all that out so I needed to figure where and how I was going to mount the new setup.
The guys over at WelderSeries recommended these
Formed notch plate, I could fabricate my own mounts, site even has a mini tutorial video.
They also recommended using their universal polyurethane mounts.
When the parts arrived I got to work hacking and grinding and figuring out where I was going to mount the cab to the frame. I followed the the old setup and decided to create one mount near the A pillar and one near the B pillar.
Eventually I ended up with these. The smaller one is for the A pillar and the bigger is for the B pillar. The cab is wider at the rear so I wanted to push the mount out as far as I could. Cut out with a grinder and holes created with a step drill bit and drill press. Little whack with the flap disc and I think I created something that might work.
Now came time to add some extra strength to the floor where I want the mounts to sit. So further boxed those sections in with more 1×1 steel. I cut some 1/4 inch plate and welded it to the underside of the 1×1 steel tubing. This might be total over kill but figured might as well make it strong.
Located the mounting holes and drilled them out.
Right around now is when I released I screwed up. When I channeled the truck I wanted a 4.5 inch channel, but in my haste to get going I put my 3×1 steel side braces right at the 4.5 inch mark and never accounted for the 1×1 steel supports that go side to side. So I have lost and inch in my channeling.
In the end this will be no big deal as the frame is narrow and you really have to get down under the truck to see the 1/2 of frame sticking out of the bottom. Than I released that if I want to mount the truck on bushings I would need some space between the bottom of the 1×1 steel supports and the top of the frame. But how much, not any easy answer to find but googling and asking questions in FB groups I found out my plan of 1/2 – 3/4 inch should be plenty. So now my frame is sticking out a bit more. I guess the biggest lesson from this is try to account for how all your materials will stack up in the end to get your final measurements. So in the end I have about 1 inch of frame sticking out of the bottom. My 4.5 inch channel is now a 3 inch channel.
To be continued, more parts have arrived so I can switch to another part of the build. I will come back to this later.
