The most impressive part on that car is the rear wheelhouse, I'd love to see that being machined.

Too bad we didn't film that. The only way we could make that part is with a full 4 axis machine. That means all 4 axis of the machine are moving at once--X, Y, Z, and A. A is the rotary axis so the part is spinning while the machine is moving up, down, left and right, in and out. We had to move in all 4 axis to spin the part around the tool to get into the tight spots. We then had to "unwind" the part to get the tool back out.
I will look for some more pics of it being made for you.

The block we started with weighed 225 pounds. Each finished wheel house weighs about 2-3 pounds. (I'd have to check and see if I ever wrote it down). Here you can see Sandwich sawing the billet log in 1/2. The chunk of aluminum is pretty big--but it was the only way to turn the corner on the chassis to feed the rear suspension loads to the front of the car and finish off the tub.

Here one of the 1/2's of the block has been mounted into the mill. We welded extensions on to the block to get it far enough away from the rotary axis so the spindle didn't crash. We then cut the welded on areas off (along with any heat affected zone).

Mr. Bruce,
That is all the pics of the rear wheel well I could find. If I find any more I will post them for you.
Thanks for watching!

Hello Scotty,
Will it have a transparent aluminum window or is that just too much to ask?
Cheers
