Progress on rebuilding the brakes has continued, as and when time allows. All the front end has been put back together, with new pipes, flexis, shoes, backplates, cylinders and so on, plus new TREs for good measure. Whoever put it together previously had never heard of copper grease, so every joint and fixing was a fight to undo, usually requiring heat to get things moving.
The other day I turned my attentions to the rear brakes, which prompted my other post about dies.
Unlike later Moggies, the MM drum is held on by a large central nut on the end of the half-shaft (as in ukdave's photo of the Z van axle). The wheels bolt to the drum (no studs & nuts, as on later Mogs).
I was able to remove the centre drum nuts on both sides, but one ended up damaged (thanks to an error in the factory manual no less!!), and both threads were u/s at their ends, preventing a nut from re-engaging. I think they'd been cross-threaded in the past.
A thread file improved the threads a little, but not the ends, so the nuts still wouldn't pick up the threads. Nor was my 5/8" die keen to go on either, and I didn't want to force the issue.
In the end I bought a nifty tool online, that works from part way along the thread, where it's un-damaged, and can be wound outwards, restoring the thread as it passes over the damaged area. It's shown below, along with a very nice old tool that can be used specifically for restoring BSF threads where the opening thread is out of action (the securing nuts on early MM Minors are BSF on the rear, later MMs like mine are UNF).
Gentle & repeated use of the above, along with ginger use of the die, saw both threads restored today, which was something of a relief.
A growing pile of bits no longer required ...

Rick,
Good progress—always satisfying when a tricky job turns out well.
We sold those thread repair gadgets when I was in the trade. There's a similar a tool for repairing internal threads, though obviously there's a limit to the minimum size it can deal with.

PS Dad's Moggy 1000 passed its MOT yesterday, so that's another that'll be appearing locally. |
Is that a pre war minor in the background? |

Mmmmmm I've had it running and drove it about here a bit. I started to do work on it, then got diverted when big Dodge's rebuild began in earnest, and it's been put near the back of the queue ever since. The body's sound although wants a few bits n bobs doing, usual stuff, but I'll get back to it sometime

No not yet, still been fiddling with various bits and pieces. The brakes are all back together and have been bled, I used a one-man bleeder but the pedal's still a little soft so I'll revert to the old two-person-with-bottle-and-length-of-tubing approach next. I've a pressure bleeder, but I doubt I'll have a fitting to fit the floor-mounted master cylinder.
Yesterday evening I drained off the very old fuel in the tank, fortunately there wasn't too much. I know that the SU pump works ok so I'll re-connect the tank next.
How's the tourer doing nrp?

The clutch finally gave up on the tourer the other day, I was quite worried because I had a particularly steep hill to get up, and it was even slipping on the level if I accelerated.
However, I nursed it home and it is now in pieces in my garage having anew clutch fitted. _________________ 1953 Citroen Traction
