That's a nice brass handle. What did you have in there before?
Do you dry or superheat your steam at all?
It didn't come with anthing but a 3/8"-16 hex bolt with a groove cut in so it could be welded to what was originally some mild steel bar stock that comprises the reversing lever- so basically a little 3/8"-16 stud.
She was a originally a car engine, and she didn't come to me that way. In the ~1960s a gentleman steamer had taken this Toledo and prepared it for use as a spare engine for his steam launch. The connections that were relevant to a car where removed and made more generic for a steam launch. He passed away before he needed it, and the man I bought it from had her stored inside in a heated indoor environment for 40years. It came to me as a crated launch engine. (eBay buy, make sure to search for local-pick only stuff if it's rare like a steam engine, and then negotiate with the seller to pay for crating and shipping.)
I had made a wood handle, but it fell apart in the outside environment Nyitra is stored.
This brass one is great, but I get nervous having too much shiny brass aboard because someone might see it and desire the brass for scrap... (Traction Engine folks have had this problem, even in locked barns...)
Well my MAWP is 200PSI. I am blessed with experiencing the huge change that happens between 150PSI going to 200PSI. The steam becomes more or less dry, and the power goes through the roof
. It also is a very odd phenomenon because going from 50-150psi seems to takes a lot of effort fueling with wood. Once you get to 150PSI it takes off to 200psi much quicker because the puffer gets more blow-by. - like a turbo spooling up on a d_i_e_s_e_l.
Also, if it's wavy carry-over can becomes more of a problem with such a high center of gravity, so what I do is run the water level maybe 50% of the Glass, and make that the set point with the fireman. Keeping the water-glass near 50% combats carry-over but it also makes drier steam - especially above 150psi.
It starts to get complicated with multiple fuels. the propane flame is going fast enough through the boiler, so I don't plan on doing a puffer arrangement while running propane.
Also for efficiency, and because it was done - Nyitra now has an Auxilliary Sail.
However, I will not run my aux sail when we are firing with solid fuels - because that is how many steamboats ended up sinking...
