Disassembling, Preparing, and Welding On Donor Frame Head #2

by on Jun.25, 2021, under Chassis

Over time, I realized that the first donor frame head was just too different to use on my chassis. It is from a 1965 and is a slightly different design than mine. It's close, but I would have to alter the pieces of it I intended to use too much and would make the replacement more complicated than it needed to be. I found a really solid 1963 one for sale in thesamba.com classified ads and purchased it. It was an exact match. It arrived in great condition and was very well packaged for protection from shipping damage. In fact, it was by far the best packing job I've ever seen. These are the pictures that I received from the seller before I purchased it:


After much consideration, I decided to use the outer portion and front plate of this frame head and removed the tunnel and bottom plate portions. I removed large areas of both to make it easier to remove the areas that were spot and seam welded. I included a picture below that shows all the pieces that had to be removed.


Here's what it looked like after everything was removed:


I then cleaned it in the parts cleaner, briefly soaked it in rust remover to loosen up the rust, and then lightly sandblasted half of it just to see what it would look like. I was very pleased! It is very solid metal with only a slight bit of pitting. Overall, it is a much better thickness of metal than an aftermarket part and almost identical to my original.


I placed the new part on the tunnel to check the fit and was surprised how well it fit. On the top, it fit very well and was sprung outward on the bottom sides a little, but was easily clamped down for a very snug fit all around.


Next, I sandblasted the entire part, sprayed primer on the outside of it, masked off and sprayed U-POL Weld #2 Copper Weld Through Primer on the inside areas that are going to be welded, and sprayed Eastwood Matte Black Rust Encapsulator on all other areas on the inside that are not going to be welded.


One final check of the fit before welding on.


Welding time! I welded the donor frame head part on and dressed the welds. Most of them will be covered by seam sealer, so appearance isn't all that critical. After many years just thinking about how I has going to accomplish this, this part is finally done. If I can give one piece of advice to anyone out there doing a restoration - just get started and don't be afraid to make mistakes. You will likely make mistakes, but at least you are making progress. Half of the challenge is undoing what you've messed up. Progress beats procrastination every time.


I sprayed some primer over the bare areas that were just welded to protect it until I start to prep for paint. Now it's time to flip it back over to install the new fuel line and to weld the bottom plates on the new frame head and the tunnel.
