The Home Machinist!

I use the water glass from LocoParts, I am working with Jeff to develop a bottom connection that projects into the water space. I prefer to drill and tap the backhead rather than use a half coupling.

Perfect!

Just give me a call I'm finishing up a coal to oil conversion on a Pacific right now and tested it yesterday awesome results with a Bagley burner.

Hoping to see that Pacific running in about three weeks!

I'm burning the candle at both ends trying to make it.

Makinsmoke. Brian, YouTube my name I put a video of the Pacific under full pressure. You can see the results with a Bagley.

Marty,
Currently saving up to have a boiler made for my loooong term 10 wheeler build, (I priced one from you last year). Why is it you recommend steel tubes vs K copper in an oil fired version? Seal welded one end?

The oil fire ramps up and down so fast copper tubes can pull away from the sheet and start leaking.
Seal welding the steel tubes at the firebox end transfers the heat into the sheet better and keeps the end of the tube from burning.

.... and roll the smokebox end?

Thks... good info to know!,

Yes, both ends are rolled. The firebox end is rolled, seal welded, then re-rolled. This keeps the seal on the water side.

That is prototype practice, for good reasons as noted by Marty.

What type of steel alloy and wall thickness would you recommend Marty?
