All Alloy Cup progress
All good thanks.

Looks great Bill, looking forward to seeing it all together.
Started to trial fit the new tail cover this afternoon.
One or two issues to resolve but it certainly
looks like an AllAlloyCup now!

Will get the wings finished off next week .
Hoping to keep the vehicle weight under 8cwt.
The large wings weigh nothing at all.

In between times assembling the camshaft, new  pistons and valve gear.
Plus this morning lugged a ton of timber from a tree that’s fallen in the garden
and which my tree surgeon neighbour kindly sawed up for me.

Thanks to all those that have helped me get this far

Kind regards
Bill G

Well done Bill.

What do you intend to use in place of the piping around the lid?

I'm most impressed by the one piece forming. It defeated me, I threw three trial pieces into the scrap!
Hi Ruairidh,

Actually it’s well done Peter , my role
in this tail cover only involved woodwork.

The mating faces will need some sort of weatherseal
so I am planning to use some piping fixed to the body
And fixed with alloy facings as per factory cars.

The tail cover itself may need some edging/piping but
Still investigating the best option for this.

Patience is a virtue!

The piping performs a number of useful purposes - I look forward to seeing what you come up with.

Hi Ruairidh 

My understanding of the body mounted 
piping is that it is designed to stop water 
From the bodyskin entering the boot, plus
Providing a closing edge that the boot lid edge
Mates to. Given the weight of the lid+ spare wheel the lid needs
to be positively located as well, which perhaps
the piping is supposed to help prevent.

If not you get chafing and stressing on the hinges and frame.
Though the spare wheel itself , if a neat fit in both matching 
apertures should steady the whole tail assembly.
Early Cups had two boot catches so keeping the tail assembly
Steady, so must have been a concern.

That is my understanding too Bill.

Add also covering of body gaps/differences in profiles.

I made my own piping using either 3/8 or 5/16 vacuum/washer pipe. The panel gap was not consistent enough to use a standard piping.

Bill, I notice that the boot skin does not turn over the back of the ply (I.e. is trimmed to the face of the ply). On my car, the aluminium skin is tacked on to the back of the ply, not on the edges. Some care will need to be taken to ensure that water does not get into the boot skin.
