Thanks for the encouragement! :(( :((

One of the problems with long-term (aka slow!) restos is forgetting how things went together....made worse by the fact it was partially dismantled when I got it! However, a lot of photos as it came apart helps....plus a good workshop manual.

There are fewer and fewer parts left unattached which is encouraging, but each step reveal something missing, damaged or beyond hope! Today I decided to reinstall the pedal connections - throttle & clutch cables plus the brake operating bar. Whilst not very exciting, it's gone from this:

However the throttle cable is at/beyond its useful life so that plus a couple of carburettor parts will be ordered tomorrow....more £££!

I realigned the engine mounts again - they just didn't seem right, so a simple bottle jack and some wrestling seems to have improved matters.

Lastly, I tacked the job I'd been avoiding - finishing off the Dynastart. I'm not particularly good with electrics and the Isetta has this unique combined starter/dynamo thing. Anyway, I bought a reconditioned unit way back and had the cooling fan blasted/sprayed, blew the finial over with a rattle can and bought a 2nd hand advance/retard thing ( I think that's what it's for!). Fortunately the 'thing' locates with a woodruff key so only fits one way. Some new nuts and it now looks like this:

I'm please with that. I'm edging closer to trying to start the thing!!........

Was suffering from a mahoosive hangover last weekend in Vegas and watched an episode of Chasing Classic Cars in the hotel room, had one of these on and thought of this build instantly. Glad you've got the show on the road, not sure what the end plan is but was impressed with the money they go for in the states :thumbup:

We're back!! After many months of domestic distractions, I finally had a fairly clear day off on my own!

First up was to look again at the drive shaft - which showed that the chain drive end didn't align with the gearbox end by about 1/2 inch. Rechecked the engine mountings to see I hadn't refitted incorrectly (thank heavens for the pics take at the time of strip down!) and all were correct.

My fail-safe is to ask the very knowledgeable folk on the Isetta Fan Club on FB and true to form the answer was simple! The chaincase is fixed to the 'rear axle' which is mounted via the rear shock absorber, whereas the engine is of course fixed to the frame mounted only by bushes. So without the body, glass, interior, battery etc the 'car' is about 150kg light........

So, it''s a bugger to get the drive shaft fitted as it doesn't line up but is now done.

Not very interesting, but whilst I was 'there' I packed out the gearchange mechanism with some bike grease and replaced the dirt cover:
Drive shaft 002.jpg
Time for lunch and to psyche myself up for the bit I'm dreading - electrics! Not my forte and made worse by the weird stuff ISO/BMW designed. From the wiring diagram I'm aiming to get the engine to turn over, but with no ignition circuit at all (so as not to start it). In the event that works...I'll move on the trying to get a spark. From what I've read, one duff connection can fry the circuitry....which is brand new and expensive!!

Back later.

great to see work starting on this again!

Was worried that if you left it much longer, you'd have to start the restoration all over again!!! :))

As with all projects.......it didn't go to plan. For a quick deviation from the terrors of electrics I thought I'd just match up the various chassis fittings with the necessary bolts (there aren't many!)....but forgot one shared when I dismantled it.

Cue a couple of hours with angle grinder and dismantling fluid.......but no success yet. Have soaked it well and will leave a week - I hear you shouting 'heat', but that's a last resort as I've spent a lot of time and money on the chassis in terms of complete strip back, stoneguard and POR15....which will be spoilt if/when the blow torch comes out.

It's quite a large diameter bolt so a stud extractor might do the job.........
