 The sheet of 4mm thick silicon rubber arrived this morning. Took three attempts to get a clean cut. Ended up using a scalpel clamped to the tool post of the lathe. Not sure why I chose 'red oxide' colour, but seems right. Hinge pin is temporary as I have to keep taking it apart. Going to try to cast the locking lever in brass and have made a mold for this. The pouring temperature is higher than aluminium so not sure how it will turn out.

Thanks.
To be honest it's a hell of a lot of work just for a radiator cap. It would be easier to make a one off mascot but that's not allowed. The calorimeter that I was originally going to fit, is too tall. This is probably pushing the boundaries of what I can get away with, but I feel that something special that stands out, is needed on top of the rad shell.
Mold for locking lever. Was originally going to try using cuttlefish bones but I couldn't find any locally so this is compressed calcium. Never tried it before and it may just shatter.

Humpf ! That was a total disaster.
As the brass was heating, the zinc in it started to fume off, so decided that perhaps this wasn't such a great idea.
Never mind thinks I, putting the brass a long way away to cool, there is a crucible of aluminium I can use instead.
Fifteen minutes later, while pouring the metal, I'm thinking, this mold should be well full by now.
Lo and behold, it's all running out the bottom.
To make matters worse when it had all cooled down, I dropped the mold and broke it.
Ho- hum. Time to try something different.

Yes, things do occasionaly go wrong for me too. That will file out Exactly what I thought. Cut and filed from a bit of 10mm thick aluminium. Still needs work but getting there. |

I love this thread. I consider myself an OK engineer but this takes it to another level. It never ceases to amaze me how many 'garagista' engineers are still active out there and the incredible work and design skills that exist amongst us. Keep it up as stuff like this helps to teach and inspire others.  |

Well, it reminds me of one of my old Dad's favourite homilies...."Tradesmans Bill, son, £1 for use of 'ammer, and another £1 for knowing where to hit it!", that about sums up Dave, I think... ..Morrag |

Thnks guys. Your comments are much appreciated.
So far this has turned out better than i hoped. Just need to sort out the locking lever link and the mounting thread. Ensuring the radius edges on the link will meet regs is proving to be awkward.

Biggest deviation from the original design. The locking lever link, roughed out. Not a hope in hell of getting the original style through IVA. I was going to make two links one each side but came up with a one piece link that should be OK and also covers the end of the cap arm.
