Made an aluminum cap for the casing, 3.00dia with a .100 step to fit the ID,
.375 thick with a .390 center hole. Another piece of aluminum, 4.00dia by
.500 thick turned a .100 step to fit the ID again with a 3/8-16 center hole.
Now for the cam tubing 3.00 OD by 2.375 ID, faced one end flipped it around
faced to length and cut C’bore. Then made a cap and fixture for the cam similar
to the other one, locating on the C’bore. With cap and screw in place I turned
the cam OD to fit the casing. On to the mill I cut the .500 slot, drilled and tapped
the 2-56 holes. Next, put the cam fixture on the rotary (4th axis) using the .500
slot for reference, cut the cam .200 wide by .200 deep, drilled and tapped
4-40 mounting holes 8x. Now I put the casing fixture on the rotary, drilled and
C’sink for 4-40 FHCS. Debur and assembled cam in casing. Back to the lathe
and soft jaws, holding on the casing I bored the cam to 2.520dia.
On the bench, I disassembled, deburred and polished the cam path.
Then assembled again.
Now I'm working on the Bolts.
