Re: Bagley burner install

Not sure how well the spark plug will hold up directly in the path of the flame. Some have success with a tungsten or ceramic rod in the path of the flame. The rod glows red hot and if the fire sucks out the glowing rod immediately re-ignites the hot atomized mixture.

Re: Bagley burner install

I see nothing unique about your firebox. Is it not rectangular in shape more or less? What makes it different? The round firebox door opening? There is a length, width, and height to your firebox and the Bagley drawing should be able to work within those dimensions. Unless your firebox is really sho...

The instructions that Dick Bagley wrote ( and are available on the IBLS website) will be of great aid in setting up your burner. Is there a particular reason you don't want to look at the original instructions. Seems the most logical way to go about installing your burner. Just a thought.

Re: Bagley burner install

The IBLS website has the proper documentation written by Dick Bagley himself regarding installation of his Sheedy style oil /atomizer burner. Search for "Bagley oil burner" on the IBLS websight. Link pasted below.

Re: Cylinder castings

If you are so inclined to invest in some sand and binder and core paste you could ram the mold and make the cores. You could paste the entire assembly together leaving only the cope to be closed. Take it to the iron foundry and simply ask them to cut the gates and risers and close the mold and pour ...
