Thanks Marek, that's what a fairing batten is.

Marek, I had a "middle of the night thought". When you gt old these become common :)
My friend Derek who has the Blower Bentley, and now another CK Vale, is another of the electric car  boffins. For the Bentley he converted from petrol power to electric for a "proof of concept", the Vale is totally electric.
Where he was clever is that he made a self contained module that could be swapped in and out quickly so that he had both electric and petrol with him at the last Tieton I went to. The base plate for both motors picked up on the same mounting points. All he had to do was undo the 4 mounting bolts of the late, disconnect the wiring and slack the chain to lift it out. The base plate ran in some carefully aligned guides so that it was always aligned for the chain run, and being larger than the base of the electric motor getting at those awkward motor bolts wasn't an issue as he never touched them after mounting it to the base plate. Mike Thorpe did much the same when he and Brian used the Mercedes at Tieton and swapped for various events, electric to gas. They had it down to 20 minutes total.
When we had the first builder's meet at my house I suggested this, and Steve Cole picked up on the guide idea, I'm sure it takes more effort to get them right, but you only have to do it once rather than every time you take the motor out.
Why am I suggesting this? Well at the virtual meeting you said you hadn't decided on a drive system Yes I did hear part of the reason. If you did as these guys have already shown is a workable system, you could have your car mobile while you figure the electrics, it would be a real shame for it to sit idle while you sort the electrics, and that is not something I would want for you. If you really wanted I have a spare genuine Honda you could borrow to get it mobile. No TAV though.

the brakes arrived. There are no obvious faults and they are looking like they should work

Hi Marek, do you want me to find what the correct matching master cylinder size is for those from the designer?

Those calipers look brill, as indeed your build work in general is a great series of vids, being L/R handed is something I thought maybe was a challenge to find in small bikes but of course i needlessly forgot bigger capacity motorcycles have discs in mirror image of each other so it's nice to see stuff like those in picture , I reckon those can be tamed with a larger mastercylinder than stock or a smaller leverage ratio at the pedal as I bet those can dissipate some serious KWs of heat and motion!!

Yes please Rhys! that would be incredibly helpful. They are Triumph sprint st 1050 front callipers

My plan for using the brakes is to use 2 master cylinders on a balance bar for a couple of reasons. one of these is that if one break line fails for some reason i will always have the second brake to help get me to a safe standstill. the other is for the other uses like installing a parking brake into just one of the lines or installing a pressure sensor into one for the brake light (which i plan on being functional).

Nice one Marek. That looks awesome. Those brakes will be really powerful and I love the video. Keep it up kid and you'll be ready when the tracks open again.

Yesterday i mocked up one half of the rear axle as you can see here. The brake callipers and disks will be on the outside of the bodywork

Hi Marek, the Triumph master cylinder to match both sides was 14 mm. The disc diameter  I'm getting for you.
The caliper runs 2 x 33.96mm diameter pistons and 2 x 30.23mm diameter pistons

That caliper calls for a 320mm disc with a minimum braking surface inside diameter of 283 mm.
Wow, tech stuff from the guy who deals with it day in day out.
One of the issues is that the wrong disc size means the pads can come together without actually pressing on the disc surface when they have worn. That can be delayed by watching the pad wear and replacing them before it's an issue.

Are you talking about a set-up where the pads overhang the circumference of the disc and so the unworn parts of the pads will eventually touch?
