Re: 1981 Mini City 1000
Tacked in the floor patch panel against the tunnel.
I have also tacked the side that will be butt welded
M-machine panel didn't fit against the inner sill so I have made a relief cut and will put an additional patch in later.
The flute in the M-machine panel is narrower than the original one so I have put in cuts that allows the flute to widen and reshape to the original floor.
Plug welds have gone really well using a 6.5mm hole and a 3mm hole in the back of the other panel
It's a day's work to get it this far, but if you rush it, it will not come out well.

Re: 1981 Mini City 1000
What's the thinking behind the 3mm hole on the lower panel? Seems like it would blow through fairly quickly, quicker than if it was just the 6.8mm hole on one side?
I was less technical with matching the flutes on the repair panels lol, bashed them into shape with hammer and dolly...

Hi Colin,
The 3mm hole was used with the Cleco clips that I used to align the panel. It helped to always put the panel back into the same spot when doing all the measuring and cutting. I just drilled out one side to 6.5mm for the plug weld. If you use your normal thin sheet welding settings then you won't blow through the hole.

Re: 1981 Mini City 1000
I was wondering the same thing about the holes. Personally I'm a hammer and dolly man myself, you'd be amazed what you can achieve with a bit of practice

Re: 1981 Mini City 1000
Started welding up the tacked floor panel this evening
Always easy to blend a butt weld when it's on an outside curve
Finished up just after the first inside flute this evening
A splash of etch primer to keep it clean until I get to body prep
I think I am going to run out of gas soon so will need to order another bottle of MIG gas

Latest updates on the mini
Finishing off the floor of the passenger side.
I might weld up the drainage holes like I have done else where.
I have a good bit of spare time between now and the end of the year so I am going to see what I can get done. Next up is the driver's side.

Re: 1981 Mini City 1000
Great welding as usual, barely visible even in primer!
Should be ready for Sunday's show in Portlaoise?

Re: 1981 Mini City 1000
Haha I wish.
I started the cleanup on the driver's side today.
I have discovered that HG rust remover is brilliant at cleaning up rusty panels. It contains Phosphoric Acid and when applied from a spray bottle 1:3 mix and agitated with a brush it removes the rust in minutes. Obviously, PPE required. I might use it on all the existing spot weld joints to kill off any hidden rust.

Re: 1981 Mini City 1000
The garage has been a bit chilly the last few days. With a couple of hours here and there you can make progress. I do have a propane heater for it when it gets really cold. Anyway on with the work.
Final cut out of the floor
Strengthening the corners of the M-machine panels before fitting
Final weld thru primer before bracket welded on
Starting to tack the repair floor panel into the floor. I work one side at a time to allow for expansion in as many directions as possible
Working my way across the floor
The inner wing will be repaired afterwards. The blocks of wood are used to screw the self-taper screws which squeezes the panels together.
