More frame work grinding, welding and epoxy primer

This weekend has been nothing but work. Today I reinforced the bell housing/trans. mounting brackets. I cut slots on both sides of the frame rail at the point where the existing brackets were welded on. I passed ¼" plates through the boxed area and welded on both sides. Also added horizontal triangular supports on both sides of the mounting ear's.

My grinding work has also exposed several metal stress cracks and tears in the right side of the frame. All the years of dropping the hammer on this thing has taken it's toll. Most of the cracks were found in the area where the right ladder bar front mounting bolt attaches to the frame. I ground all the ones I could get to and otherwise used a cutting torch to slit and clean the cracks a bit. After that I was able to use a Lincoln 125 MIG to get in and weld up all the stressed areas. This took awhile and I ruined 3 tips and really over heated the gun. Since this was all ¼" to 5/16" plate, or channel I used .035 wire. All is good now but the finish grinding was a difficult.

What a job! Welder's and fabricators what ever you charge can't be enough...

More frame work

This week I took the front leaf springs to the spring shop. The spring leaves were chrome plated back in the late 60's. The main leaf is the only painted leaf in the stack. I had the shop break down the spring stacks to see if we could salvage the old chrome. Thanks to the quality of the old chrome work we were able to polish and save them. Their not perfect and since this old U will be a street/race car I can live with a few pits and rust stains. I also had new bushings made for the spring eyes and fabbed up some new U-bolts which will go to the chrome shop.

Today I got back to welding the frame around the mounts and other areas where parts were held in place by the old rivets. I'm grinding down to bare metal and then using etching and weld through primer to seal it down until I can get a coat of epoxy primer on the whole frame. I also neutralized the acid treated areas and washed the whole thing down with a trisodium phophate cleaner.

As I disassembled the chassis I inspected all the parts and labeled them all as to their location and arrangement. Right, left, front, back, etc. I am going to rebuild both the king pin assembles and have new u-bolts made for the front leaf springs. Other than that everything just needs to be cleaned, polished or plated.

11-08-2009 06:05 PM Cleaning the frame

Today I attacked the frame with oven cleaner, Dawn and the pressure washer. It cleaned up well. After it dried I used an old rust proofing wand and blew a phosphoric acid based rust converter into the frame rails. The oven cleaner really does a good job and its biodegradable.

The frame measures 12'. 2 " long. It's boxed all the way back to where the boxes are located that house the front of the ladder bars and the pass through bolt they pivot on.

11-07-2009 08:46 PM Brake caliper brackets
GM big car disc brakes were added to the straight axle back in the 70's. The home made brackets are 5/16" plate steel. They were very strong, so I decided to use them to mount the front fenders. You will see one bracket that's welded up and finish ground. The other picture is one in the rough when I was just mocking up the fender mounts. They will go to the chrome shop for plating.
