[SCOTI]

One step forward, 2 steps back.

I've still been @ it but haven't really made 'progress' because I'm doing stuff twice. I was reading through various threads & came across one for "c-notches".... http://67-72chevytrucks.com/vboard/s...d.php?t=393867

There was some excellent info being discussed & shared & board member Lakeroadster helped several of us out w/an engineering perspective. With his input, I realized the c-notched area of my frame was much weaker than stock (which is much weaker than I anticipated).

I figured that modified area of frame would be about the same strength as stock w/the thicker .250" material for the home-made notch & the inside boxing. After running the specs through some calculations, the results were scary.

So, I asked more questions & started contemplating various options. I went ahead & cut up the same area on another frame to get the contours necessary to build a 'truss' section above the c-notches. This will add the much needed height for strength while keeping the flow of the frame.

I did a bunch of measuring, cutting, measuring, cutting, grinding, measuring, grinding..... well you get the idea . After all the effort, I have the outer portions of the trusses complete & tacked in place. I started cutting some re-inforcement plates that will be welded in between the original frame & the new sections to help tie things together better. Hopefully I'll get them trimmed down for a good fit & start welding things up during the week.

All the various clamps & steel is to ensure the new sections are square w/the top of the original frame while remaining square to each other. The proof is in the pics....

The new trusses add 2.5" above the top of the c-notch plate yielding a total 4" of reinforced material above the notched area. I left .500" room to be able to install a rubber strip that will be under the shallow bed floor cross-member that is in that area.

Lookin' good Scot, man you jumped right on the modification didn't ya!

Using the other frame for the truss was a great idea.

Great work.

I was really hoping to be posting up pics of a rolling chassis @ this point in time. This set-back prevented that so I'm really pushing to knock the repair out so I don't grow stagnant.

I was going to PM you about the updates because I didn't know if you checked in on the build section very often. Thanks again for your perspective & suggestions. If there's ever anything I can do to 'pay it forward', please let me know.
