7075 alloy Amal carb parts
I had to do an emergency job which broke me off from the kicking post. Its 7075 alloy jet holders and bottom nut for Amal carbs. They are spectacularly complex little fellows but really nice to make, i’m developing a real passion for 7075, it just takes longer to clean down the machines afterwards as its more ‘bitty’ than titanium.
the thread on the bottom nut which screws into the holder is 3/4 x 26 tpi (bsb), this isn’t true cycle thread as its 55 degree angle whereas cycle thread is 60, but as they are matched threads it matters not a jot.
they are now down at the anodisers for hard anodising in clear, i’ll put up a photo when i get them back as a ‘before and after’.
