The components are constructed using the CWU machine lab.The burner body will be bored and turned on a lathe, and then holes will be drilled and reamed on a mill. Photos of construction processes are shown on Media page.

• The Burner Body is made up of a threaded pipe with a flange. The pipe and the flange will be machined separately and welded together in order to save time turning the whole thing out of cylindrical stock. Burner body drawing is shown in appendix B 20-0001. 

• Internal geometry of the nozzle was bored out on a lathe.

• The Intake was the most difficult to manufacture as it had the most complicated features, and the work holding was an issue as the outside was tapered. The cylindrical stock was first drilled out on the lathe to get a through-hole for boring the internal taper. An arbor then needed to be designed to mount the intake in a chuck or vise so the outside taper and the flats could be machined. The arbor also makes it easier to tap the holes in the side to accept the socket head screws. The drawing or the Intake is shown in appendix B 20-0004. 

• The inside of the injector was drilled out of threaded rod. Outer features were then turned on a lathe and the end was threaded to attach to the injector bracket and accept the propane line. Injector dimensions are shown in appendix B 20-0005. 

• The intake valve was knurled on the outside and drilled and tapped in the center to be threaded onto the injector. 

• The injector bracket was rough-cut on the bandsaw, and final dimensions were machined on the mill out of a flat plate with appropriate holes drilled and tapped shown in appendix B 20-0003. Graduations were stamped on the side of the brackets showing the corresponding intake setting for a certain propane pressure setting.

• The forge couple was not fully machined as it will be easier to buy a pipe coupler and drill two holes in it to accept locating pins on the burner body flange.
