We are currently making these parts in house but are looking at subbing them out to someone with the proper machine to run them. Currently the turning work is done in our bar fed CNC lathe, and the flats and hole is done on our Haas mill. Total machining time per piece is about 4.5 minutes, not including load & unload time. It's the load/unload time in the Haas that's killing us mainly due to our crappy fixturing that requires a manual operation. A 4th axis with a hydraulic chuck(s) would go a long way to resolving this.

Before we run out and buy another CNC lathe that has a Y axis, live tooling, and a sub spindle we thought we would see if any one wants to do this at a reasonable price. Most dimensions are not critical and machine tolerance is OK.

Currently we are making these from 3/4'' 303SS round bar, but are thinking about moving to 7075 aluminum. A normal run for us is about 500 pieces of each part, every couple of months.

The attached zip file contains drawings of all 3 parts in several file formats.
