Re: Tube square footage

I'll get beat up for this but here goes. There are a bunch of wonderful applications for small steam. Boats, some cars. Those sort of things. But what hasn't worked well is trying to displace I.C. engines from applications where it isn't just esthetics but other factors. A trash pump is needed very ...

Re: Tube square footage

Is this for a fire tube or a water tube boiler?

Re: 1893 Marine Steam Engineers Manual and Directory

Perhaps an old steam powered motorcycle? Having sat for way too long in presentations about EMP threats, my impression is that the practical threat is to longer wires and low powered electronics. An old dial phone will stand a lot when hooked to a land line. A cell phone would be largely unaffected ...

Re: 1893 Marine Steam Engineers Manual and Directory

I'm an amateur astronomer and a disaster preparedness worker. We use the Carrington Event and a few others like it to plan for disruptions in the infrastructure during and after such a solar flare. The growth of fiber optic has worked in a good way to moderate the communications damage. It is mostly...

Well, my neighbor lady wanted it to grow asparagus but she decided that it was too shoddy.

Re: Modern History

That's so true about the epoxy issue. Lots of disposable gloves and face protection. And once you develop an allergic reaction you are there for life. Be careful! It depends so much on your skill set as to whether you end up with a decent looking hull. The hull I just threw away was a text book case...

Re: Modern History

Interesting numbers. Thanks! I really agree with the fabrication advise you give. I never could weld worth sour apples until I got a decent MiG machine. Now maybe as good as wormy apples. I still like wood, including plywood, better. For me, steel suffers from what I call the 'clank' factor. Too muc...

Re: Dynamo/Gen Set

I'd like to know more about that feed water heater. Cute. Wonder if it could be scaled up a bit and whether it's real any better or lower loss than a tube within a tube type. I'd been thinking about maybe 18" long with a 1/2" copper pipe within a 3/4" pipe for my 3 x 4 launch engine. Also, I have a ...

Re: And Now for the Twin

I'm not nearly as familiar with stationary and boat steam engine designs as I should be. I am very familiar with locomotive practice. As you point out, one end at least should be adjustable and accessible. In railroad practice, though, the piston end is usually tapered with a lock nut and the cross ...

Re: And Now for the Twin

I think he's working on his piston rod, piston and crosshead. I like your valve gear solution but I don't think it would stand up to the the forces on the piston rod.
