Starting with about 4" of aluminum tube,10mm O.D., and 8mm I.D., use a Dremel with metal cut off wheel to create the two-prong, end-shape shown. Technical drawings with dimensions are available for download above, but it really comes down to 3 cuts with the Dremel. First cut down the end of the tube (about 7mm deep and 3mm away from one edge of the tube). Then cut the tube 7mm from the end, leaving the smaller tongue section of tube left standing. Then cut a 1 to 1.5mm slot down the center of the tongue to create the two prongs shown in the picture. File the edges so nothing is sharp, and adjust as needed with a file after test-fitting the tool. I welded on a t-handle using left over tubing (always looking for TIG practice), but that's not necessary if you're not a welder. If you need more leverage to rotate the jet, you can add a collar lock to serve as a handle, or drill and hole and use a long bolt in lieu of my T-handle (or use pliers on the tube if you're an animal
).
