Re: Steam drum

To be a Code Boiler, welded or not, requires material certifications, and if the boiler drums are not seamless tubes/pipe, then radiography is required. That is plenty expensive by itself.

Re: Another Sidewheeler Building

A long time needed to make the sidewheel splash guards, built up with epoxy joined Mahogany veneer layers and a marine plywood base. The structural part of the guards is all made from IPE, known as the worst wood to work with, being ultra strong, ultra heavy (it will not float in water), ultra expen...

I think the sequence of picture uploads is the last upload is the first picture of your post.

"In Finland boilers under 1.5 bar (72.5 psi) absolute pressure (0.5 bar gauge pressure) are not considered as pressure devices that need inspection. If condensator is used, that would give good enthalpy difference, even better if steam is superheated. Steam volumes would be comparatively huge, but h...

For a boat in the 18-22 foot range a good used steamboat can be had at reasonable prices, depending on what is considered reasonable.

Re: A Funny Looking Slide Valve

Excellent work, as usual from you. The oil slots on the slide valve is new to me, although I have only been involved with the study of steam engines for 70 years now.
