Some more machining pictures for those interested. I posted a few in our 66 Vette build thread, but I thought this would be a better place.
I'm building these for a customer of B&B Classics. Billy has done a lot of upgrades to this guys '67 Chevelle 300. The car is beautiful, a very nice, clean car. It has a BBC 572 that Billy put a Hilborn fuel injection unit on it last year. The owner wanted to dress up the appearance over the sheetmetal formed stacks. I came up with this:
Lower stacks, one operation in the mill, one in the lathe

After turning, these are complete. Two flipped over to see the bottom side

Here is the top cover plates all machined, three setups in the mill including 3D machining the inlet radius

this one shows the tool marks left (totally intentional) in the inlet radius

The screens are cut on my laser. It's really a marking or engraving laser, but it will cut this 0.032" aluminum. There will be two screens in each horn with a layer of pre-filter material in between them.
Hope you guys enjoy the pics!
