I'm looking to get a part for my car machined. its basically a block of aluminium about 100x100x25 ( mm ). The centre will need machined out to have a roughly 80mm hole through it with a 75mm diameter lip at one end. at the 4 corners, i'd need 4 bolt holes drilled. I'd quite like the outside outline profile of the block to have slight curves to it to match the shape of the part i'm bolting it to.
Does anyone have any idea of even a ball park figure of how much something like that would be?
I suppose the possibility of multiple runs of it would be possible if others want to do the same mod as I plan. ... but that wouldn't be hundreds.
Its basically one of these, but deeper.
