Foundry Fuel Injector (Take I)

Here is my first attempt at a foundry fuel injector. It is designed to burn WVO. It also has a propane hookup for pre-heating, and an air hookup.



This is the hookup for air. It connects to the air compressor. I will be using an air compressor initially because I have one, therefore it was convenient. Most folks use a blower.



This second hookup is for the propane. The propane is to pre-warm the foundry. Once the WVO is burning, the propane may be turned off. The connector is not exactly straight. I had trouble getting the tap started on the pipe. Perhaps I drilled the hole crooked.



This is the oil hookup. I put a valve inline to shut off the oil. Below the cutoff value is a quick connect.



This is the bottom of a five gallon bucket. The bucket will be used as an oil tank. Initially the oil will be gravity feed. Eventually I will probably pressurize the oil tank. Here the bucket is hanging up. I was checking for leaks. None so far.



I read that the oil tube inner diameter needs to be greater than 1/4". I used 3/8" tubing. I used air fittings with an ID of 3/8" also. Perhaps tomorrow I will test out this contraption.
