This is the process by which I used to make spool valve bolts on a CNC lathe (in this case a Haas HL-3 lathe) A friend of mine was inquiring how I’ve made them in the past, so here we go. There are always differences from design to design but much of it is applicable to other hollow bolts with o-ring grooves on the outside, like those for Shockers, Ions, Luxes, and similar. This particular bolt is for a Quest-like marker, although noticeably shorter because the “tip” will be made separately then secured later.
Here’s the program progression:
1. Face to a finished surface on one end
2. Centerdrill in order to accept a live center
(advance live center)
3. Turn outside profile (rough,finish) in this case one tool is used since the part has lots of undercuts.
4. Cut outside o-ring/bumper grooves (rough,finish)
(retract live center)
5. Drill thru to other end
6. Ream to the finished diameter
7. Partoff, or in this case partially partoff then remove by hand as to avoid the part getting smacked by the chuck jaws.
Afterward the bolts need to be honed for a nice internal surface finish.
