Instrument needles - Austin in the Shed - 28-10-2017
I've just purchased a 20's smiths silver faced oil pressure gauge,the flange mount type.It's been butchered a bit by someone trying to remove the needle,which is missing along with it's mounting rim.
Does anyone know a manufacturer of them,or where I can buy one,

I use something similar to this Bill: http://www.ebay.co.uk/itm/Wristwatch-watch-hands-hand-remover-lifter-presto-type-tool-repair/300645449436?hash=item45ffdd7edc:g:YRoAAOSwEK9Trtlz
I have also adapted needles like this in past successfully: https://www.ebay.co.uk/itm/Replacement-GP-Watch-Hands-Mixed-Sports-styles-1-20-0-70-0-20-Set-of-3/222524875041?hash=item33cf842121:m:ml_MAPgdeDhUKjvXdSqDsdQ

Dave,
Probably the best way to make these and the engraved instrument faces with paint infill used on early cars would be to use a photo etch method that is the same as used for diy PCB manufacture. The materials are very inexpensive. Same method would suit all the chassis plates/ couch builders plates etc.
Just been looking on ebay. The materials are less than £10 for a small quanity. For aluiminium use NaOH to etch. Its cleaner and cheaper than ferric chloride. There is a book on how to do it... workshop practice series no36.
Looks tempting to give it a go.
At work I get profiled shims and gaskets made this way in large quantities. Ah yes I suspect that might suit you! You can make solid copper head gaskets like this and use the photo etch to leave a raised land round everything you want to seal. Because there are no cutting tools it all stays flat and scratch free.
Regards
Rob
