![]() 1860 forum posts 121 photos | I am in the midst of designing a 2" scale boiler for a customer who wants to build a traction engine (his own design). The drawings I have on file typically show a plug in the (smokebox) boiler end plate, but to this day ive never seen anyone fill their boiler this way. Is this now a redundant item? |

2276 forum posts 801 photos | Fizzy, Plugs in the firebox tubeplate are access holes for washout and inspecting the inside of the boiler. Model steel boilers in Australia require one at the lowest point of tthe firebox and one above the tubes. (Not sure about the requirements for copper boilers but would advise to do so). Water fill points are normally at some other position. Paul.

![]() 528 forum posts 79 photos | The front tube plate (smokebox) on my 3" scale Marshall has the washout plug at the top, I use it for a hose pipe connection, the position allows you to blast all the gunge off the top of the firebox crown. Mike. Edited By MichaelR on 27/05/2018 16:09:31 |
