Yamaha R1 7075 alloy oil cooler blocks and bolts

A customer required a pair of blocks designing and making to improve the oil cooling system on his race bike, these are what i’ve come up with.

The threads are 3/8 NPT, thats an American tapered pipe thread. They aren’t polished, just deburred as they are off to the anodisers in a minute, i’ll put another photo up when i get them back.
