The burner on gas-fired Thompson Type-Casters was designed over a century ago for use with manufactured gasses such as coal gas and "illuminating gas." While others have run it to their satisfaction converted to propane, I was unable to do so. (That is, I could get it to run using the same conversion methods, but found the results unacceptable for my own shop.)
I have therefore adapted a non-Thompson burner for use with my casters. This essay (set of Notebooks) chronicles my experiences both with the original Thompson burner and with other burner adaptations. This undertaking, while on the back burner for the moment (pun intended, of course), is by no means finished. My existing setup is minimally adequate for my present purposes, but it is by no means perfect. I fully expect to revisit this project in the future and to develop it further.
Disclaimer and Warnings
In this essay, I am simply describing what I did with my own Thompson Type-Caster. I am NOT suggesting that you do the same with yours, or indeed that you do anything at all with yours (or with any other gas-burning apparatus). If you do choose to do anything with any gas-burning device, you take upon yourself the full responsibility for anything you do.
Please note that this disclaimer is not merely a formality. Propane and related fuels are potentially very dangerous fuels which have unusual, counter-intuitive properties. Click through on the link (blank image) at left for a discussion of some (not all) of the dangers.
Odd Terms and Units
They don't make this easy. LPG, WC, NPT(F), CGA, POL AN, etc.
The Original Thompson Burner
The original Thompson burner (or at least the original Lanston Monotype-Thompson burner). Its adaptation to LPG using the Skyline method.
Forced Draft and the Thompson Burner
An attempt to improve the original Thompson burner, running on LPG, using a crudely arranged forced draft. I found this method to be unsatisfactory.
