Hello folks, can anyone tell me what the 1/2" x 40TPI threads shown on the underside of the steam chest drawing are for? Not having any assembly drawing or instructions i am at a loss as to what they are. Many thanks, Phil.

I suggest that you ask the question over on Model Engineering Clearing House Forum where there is an active build and a couple of owners who are members.

For removable plugs so you can see the valves and ports for setting the timing. The drawing in ME shows them as 3/8" x 40
