I've got a bunch of these, I'll post two of them, sometimes they are not all that glorious but serve a function.
The first is a vacuum T. The parts stores only carry plastic ones, and on my home built blow through carb turbo car, plastic simply isn't gonna cut it, for my own piece of mind I decided to make one. I took two bolts, and machine them in my POS jet benchtop lathe, One was machined on both ends, drilled to the end of the barbs (not all the way through) and the barbs were cut on the lathe. The third fitting was done the same way. Then I tig welded the pieces into a T, and finished drilling all the way through.
The second home made part was for the carburetor on the same car. The rear powervalve is set up different than a standard holley carb, it uses a spring to push the valve closed, so normally it's always closed, the the PV pickup functions as a retainer for the spring, it gives it something to push on, and as a extension to pickup fuel from the back of the float bowl on hard acceleration. This is only on the rear float bowl/metering block. The PV housing was made from a bolt, machined down on that same POS jet lathe. The extension was also a bolt, machined to size, and drilled. Things were really thing, the housing fits tightly around the PV boss, and so things were just tacked with the tig, and sealed up with some JB weld.
