Shop work

The older aquarium air pump used to dry my biodiesel broke. One of the very useful bits it had on it was the ability to change the amount of air that went through it. That allowed me to bubble softly at the beginning to not emulsify the wet biodiesel. Unfortunately, I did not understand its importance until I ran the new bubbler at it's max speed at emulsified the wet biodiesel! So, while it is possible to purchase a bit that will allow us to change the amount of air going through, with the shop as decked out as mine is, we want to make one. So last night my oldest boy and I worked on the lathe and the mill with a chunk of brass to make one. We have the biggest part done and tapped now so this evening will make the screw to adjust the amount of air moving through. Hopefully that will be done tonight and we'll take a picture and put it into production of biodiesel in the back.
