Brake drums

The desired drums for my Monoposto Seven design are 7" Girling pattern. Anyone that has tried to obtain these lately is in for a shock. They are not available in any form and the new parts are on infinite back order. The problems appear to be Brexit related and surrounds the import duty/VAT payable in advance for non VAT registered  dealers.
 
I cannot wait for such deliberations and another solution is necessary and relatively urgent if I am to get to a rolling chassis this year. I put together what I think is the likely implementation using a Ford Fiesta MK1 part (which is still available but out of production). The problem is the same no matter what part you start with, it will require turning from what you have to what you want. The advantage of the Ford part is it appears to have plenty of extra material to create a part close to the Girling drum.
 

 At this point in time I have turned out an example. The conversion was a complete success despite my rudimentary turning skills self taught of course.
 
All I have to do now is make another 3.

Monoposto Jan 2025 onwards

 Jan 2025 - Battery management   Total loss system needs careful thought about energy storage during a race meeting and the necessary charging scenarios. The only approach is to estimate worst case. This system has three modes a) Monoposto running from 20AH Lithium M/C battery and expected duration b) Charging Monoposto battery from RV battery and c) Charging RV battery from the van starter battery during going home time.  Here is a table predicting the life of the M/C 20ah Lithium battery and RV battery (donor). AH = Amper Hours WH = Watt Hours. The table assumes the M/C battery is charged from the RV battery at some point in a two day weekend. a) Running from a M/C battery the table labeled LOAD shows 2 days running charging is expected after 10 runs from the RV battery. It is assumed 20 runs is a two day weeked and only loads the RV battery less than 50%. b) In the event of deciding to charge from the RV battery it must be done via a special charger that is designed fo...

 Progress Jan 2024 till Jan 2025 Jan 6 2024 - Remote gear linkage (again)   The remote gear linkage with the Type 7 at remote end turned out to be too heavy so an alternative had to be found . More design and fabrication. Video link https://youtu.be/GN3WJG4qLAQ  Jan 8 2024 -  Oil pickup pipe, baffle and reinforcing block for securing head long bolts   This engine is pressure fed so it needs a pickup pipe that is immune to gravitational slosh on corners. This was designed in brass and soldered. The baffle is an aluminium plate. The extra securing blocks for the head can be seen on the bottom left.  Jan 24 2024 - 2CV clutch conversion progress More progress on the clutch conversion, most of this video is informative but please ignore the aluminium adapter (in red) as this turned out to be the dead end part of the design. There was no space for that part. See Terry Griffiths design (and his conversion notes). The main progress hear is the flywhee...

                                                   Monoposto Seven Build The start January 2022 After the successful build of my Super Accessories Special my attention wandered with a view to creating another car. It was not exactly my intention to build another car but the drive to tinker with something else automotive was unstoppable. The idea came as a result of a video I made during the 2021 hill climb season where four Austin Seven special owners got together at Forrestburn. Paul (one of the owners) offered to help me with the design of my new car. That was a fantastic offer, not to be refused as Paul is a prime mover at Vintage and Classic Workshops in Penecuik near Edinburgh.   My vision of the car, which is not necessarily shared by Paul, can be seen in this link . Paul correctly thinks the body panel beating required w...
