Turned out a couple days ago that I'm 2 weeks ahead of schedule in Machine Shop, so the head instructor had me do an extra credit project (YESSSS!!).
So I had to make an adapter for our cleaning rods to mate with rifle brushes (two sided female adapter), with 8/32 (brush) and 8/36 (cleaning rod) taps. Took me 10 Hrs. 42 Min. to design (drawing blueprints) and produce the prototype from scratch made from 1/4" x 2" 1018 CD stock (the real thing will be made of Brass). I made it .850" long and exactly .215" outside diameter (to fit inside .22 caliber bores), with a knurled (sp?) end where the cleaning rod would screw into the adapter. It was done entirely on a lathe and has perfect dimensions ![]() Good part: Head instructor liked it and said that my design and prototype will become the standard for a new set of Machine Shop projects which will include making adapters for shotgun brushes along with my design. Best part: I get to design the lesson plan for my rifle adapter.........and all these sorry asses will have to draw their own damn blueprints. Bad news is that the instructor kept my prototype so I have to make another one for myself, and make 2 Brass adapters of the same: one for me and one for the instructor. Here's a few pics: The Blueprint (the finished product is at the school right now). Just for kicks and giggles I compared my design to the school issue (I think Hoppes?) and these were the differences I noted: Hoppes: .204" outside dia; 1.004" in length, a line carved into the piece designates the end which the cleaning rod screws into, and no 45 degree chamfers are on the piece. Mine: .215" outside dia; .850" in length, knurling indicated the endin which the cleaning rod is screwed into the adapter, 45 degree chamfers on both inside and outside dia; and both pieces have the same wall thickness (between .034" and .036"). As you can see, I'm going to be sinister and utterly cruel by making this project as difficult as I possibly could for those sorry asses who are going to be doing this ![]() ![]() And My Beretta Armorers' cap ![]()
