A bit of a delay since the last post - quite a lot of things going on outside of blog land.
Two posts ago I showed a method for sealing off the end of a stainless tube. But to what end? I was brainstorming on a easy way to make a pintle injector. I took the tube shown in the previous post and drilled 8 holes in the end. The result is less than optimal because my mill's spindle is really too slow for the size hole I need. But the result was promising.
These tests were run with water in the center and air on the annulus.
