On occasion, I am asked as to how some of the parts are made. Here is a picture of a Mk IV nozzle holder, still in the mill, after the vents have been milled. Prior to the milling of the vents, the nozzle holder is first machined from bar stock, on a turret lathe, and the flats are cut on a manual 4-axis Sherline 2000 milling machine. The nozzle holder still needs de-burred.
Here is a picture of a batch of freshly band-sawed brass pieces that are ready to be machined into J-Head nozzles. They first need to be prepared by machining them into blanks that can be finished in the Harding DSM-59 turret lathe. However, I don't always make all of the blanks in-house anymore. Sitting on top is a blank that I had CNC machined at a CNC machine shop. Once the blanks have been machined, to the stage of the CNC'd blank, it is ready for the turret lathe.
After I am finished with the initial 2 operations that are required to turn them into blanks, the brass pieces will look like the blank on top and will be ready for the turret lathe.
