Most
of the past couple of weeks have been spent organising and equipping the new
garage as well as clearing out the old one. I have now built a workbench, layed out a tool board, put up shelves
etc. In between these tasks I have made time to continue cleaning up the
chassis. I decided to start by removing the rough cut floor pan remnants away
from the supporting lip that runs along either side of the tunnel. Initially I was using my air chisel, but found it to be quite severe and could easily damage areas of the old metal that I was keen to save. So, I opted to do it by hand using pry bars, long screwdrivers and hand chisels. I basically worked my way around the parimeter popping off the spot welds one by one:
In theory this should have been a quick win, but the reality was that it took 10 times as long owing to all the past botched repairs and inconveniently welded parts that had be stuck together in areas that should never have been joined. For example; one seat runner was welded to the tunnel rather than spot welded to floor pan.... and then there were repair plates that had been placed over severely rusted areas without the old rot being cut out first.... Anyway, little by little I made progress and took the excess metal off cleanly.
I then switched to my trusty electric saw and made a horizontal cut to get rid of the overhanging sides of the bolt:
When I got the cut flush I simply tapped the piece out:
The next task will be to wire brush the old paint, underseal and dirt off of the framehead and bottom plate so that I can assess how much metal work needs replacing. To make this impending task easier I decided to build a simple wooden pan rotisserie so that I could reposition and rotate the chassis as desired without breaking my back each time. I constructed the framework entirely from scrap timber that had been left by the previous occupant and thanks to the fact that I can now operate my power tools (electricity, beautiful electricity, I am loving all 240 volts of it!) I had it built in no time. The only problem I came accross was how to secure the rear frame horns to a pivot piece. The original bolts were simply not long enough to pass through a piece of wood and reach the internal threads. I looked about for equivalent bolts of the same diameter with a longer shaft, but they were either ridiculously expensive or had a different screw profile. I ultimately concluded that trying to force a modern bolt to fit could lead to the threads becoming deformed or weakened. My garage neighbor, Tony, then came up with a simple solution; take a thick length of dowell (slightly oversized), taper the end and screw it in so that it threads itself:
I was dubious at first, but decided to give it a go and was impessed with how sturdy it seemed. I added a piece in on the other side and cut the dowell to a desired length. I then gently tapped on the connecting wooden pivot piece using a rubber mallet.
This joint should hold well for the duration of the pan restoration.
Here is the finished product with braked swivel casters added and the pan mounted up:

Next
up was a seized bolt that was holding the pedal mounts in place. I tried
everything to get it turning – penetrating oil, heat, wire brushing – but the stubborn
little thing did not want to budge! I felt the only way forward was to
carefully drill it out. I started by centre punching the top of the nut and
then drilled a small pilot hole. Using a wider drill bit I slowly widened the
hole:

took some time a patience, but I was pleased with the outcome

Simple and effective! Now I am ready for the fun to begin....
