And again four weeks went by.  Sort of last minute I found that some of the brake shoes had too much play on their pivot pins to my taste, so I decided to have them bushed.  Sadly the machinist took a little longer then promised, and for a two hour job the shoes were gone till yesterday.....
Of the shelf 20mmx23mmx30mm bushes where then quickly pressed in, and this morning I could'nt wait to test the brake lining tool!  All went well, and in two hours time both sides of the rear axle were fully done.  The big advantage of this approach is that all can be fitted in one go, backplates and all, since no adjustments need to be made afterwards.
Hopefully tomorrow the rear axle can be finished and fitted!

Merry Christmas to all!!!!

O O, time for an update!  At least the rear axle got mounted under the car in 2021, albeit the very last day!  The rest of the holidays more real work then planned got in the way of the Lambda restauration.  However the past week Covid intervened, and twe were all under house arrest!  A good thing having the workshop at home it proved once again!

Some serious work was undertaken the past week in fitting and adjusting the front brakes, mount new bearings in the front hubs, and fit all together.  The track rod I made was too wide by 15mm, so there was no other option then start over and make another one....
I then finally fitted the engine and gearbox, checking all fitted together with ease, and double checking on the clutch operation.  The shaft between the gear lever and the box proved 4mm too long so had to be slightly shortened to get the gear lever to be perpendicular to the tunnel in neutral.  After this the brake compensator shaft couldf be fitted as well, making the lower end of the engine compartment almost complete!
Fitting the rear shock absorbers required some adjustment to the body, as there was not enough room for them to move freely, which was resolved by making a special spacer moving them slightly outwards and removing a bit of the body!
I then could not resist making a probe fit of the carburettor and air filter, and check choke and accelerator connections, as these still need to be adusted and painted.
I also took a lot of time fitting the steering wheel and advance control mechanism, as, due to a fault in the parts manual, where a little spring is shown in the wrong position, the whole steering shaft had to come out again to correct this...the disadvantage of assembling a car without having disassembled it.....
But al in all huge progress has been made the past week...mind that almost every bolt fixing these components had to be made, since no bolts came with the project.  It is a quite time consuming matter, since I want to keep all the treads BSW like original so modify long M8 bolts by cutting new treads....
An intermediate task was to give the underside of the rear mudguards a good thick coat with underbody protection, as I fear the aluminium will be dented quite easily by little stones thrown against it by the wheels.
Next week I hope to pick up some wheels and then the first task will be to bring the car to the radiator man to get the radiator made properly.
Getting closer!!!

BSW bolts are available from several suppliers in the UK.     (Post Brexit it may be easier for you to make them rather than try to import them of course).

Yes indeed I did (pre brexit) order some and also castelated nuts etc in various sizes, but sort of forgot about certain items, or did not have sizes available at that time yet.  It now however is very expensive to get small items over, and just does not seem worth the hassle....

On threads: does anyone know the thread size in the valves underneath the two little tanks in the engine compartment?  I need to find some way to connect the tubing to measures 14.8mm in diameter and is 20TPI or 1.25mm pitch, and I don't seem to find anything that comes near.....

Could it be 9/16TH INCH X 20TPI British Standard Cycle thread? It would be a bit undersize 9/16 = 14.29mm.
Tracy tools have taps and dies:-

Have  a browse, they have a lot of info and most sizes, although not M15x1.25.
If it is for carbon steel (Grade 8.8 like most bolts) rather than brass or aluminium, or mild steel buy HSS taps and dies not carbon steel as the latter will wear out or not even cut.
