Been working all morning on getting some of these ready for assembly. Already had them bead blasted and passages drilled, just polished most of them, te-tapped all the threaded holes, resurfaced all the mating surfaces including where the seat screws into the bottom of the bowl which is almost always a mess, where all the caps screw in, internal threads where the main jet screws in, etc. Some of them I get in have been drilled out so 3/8 studs won't work or the threads are too bad to use so I have a jig to drill them out, thread them with 1/2 x 24 threaded brass stock, with silver solder to hold it in, have a drilling jig to drill the holes and thread them 3/8 - 16 so they are correct for an OF. Most of the flanges are bent to some extent so I run those through a process to flatten them so they don't leak air around the flange. They will all get bushings for the throttle shaft, too, I need to make a whole pile of bushings before I get much further.
Made a bunch of little parts last week, made about 20 of each one shown, these were just what was still laying on the bench.
Tired of standing in front of the lathe and the bench, coffee time, just thought you might like to see how I do these.
Back to the shop, back to the shop.
