January 4-5th update
Took a break from the mini over the holidays, and put my KTM 200 engine back together after having the cylinder replated. It's actually my first time back riding with my son after I broke my wrist 3 months ago! it was freezing the day we decided to go ride but still it was fun.
Started when I left off, the dreaded chewed up top dash rail.
the lip that was spot welded at the wind screen opening was chewed up from removing it and heavy corrosion.
so I cleaned up the underside and top side with the wire cup bit in the die grinder and a surface conditioning disc.
the lip is formed back on itself at an acute angle for the windscreen rake angle so needed to be bent at a right angle to get the tool access for cleaning back to bare metal.
this end is the worst damage that needs repaired.
so it got chopped out and replaced.
its very thin gauge, so welder turned right down and just pulse weld, here's the back side which is hard to get at to clean up.
I use this tapered carbide burr in the die grinder very carefully, this weld is hidden anyway when the edge of the panel is formed back to the wind screen rake angle and installed in the shell.
other holes from drilling spot welds out to remove it are plug welded up with the block of aluminum as a backer then ground smooth.
Then test for the panel.
Zinc primer is so so messy from the spray can, I keep forgetting to decant into a container and just brush paint it...
Now spot weld it on.
The ends might have originally had a flange to weld it to the A post but mine are long gone, so I opted to seal weld and then grind smooth.
the right side was a pain and I'm still not 100% done with it.
but I got some primer on for now.
starting to look like a mini again.
I also ordered the front panel, both wings and some bonnet hinges from M machine in the UK, it's the same company who made my floor for me and a few other specific early MK1 panels. The front panel is a special order (3-4 week lead time) as it has the full skirt shape rather than the ends being cut away, a design change some time in mid 1960, I was told, to enable the drum brake cooling
In the meantime while I'm waiting for that, I'm going to work on the bonnet and boot lid.
