Re: American Walking Beam Engine

A little off topic, but what are the advantages of using poppet valves in a walking beam engine?

Re: I'd need help with my lathe v-belt drive

Are there any rough spots when you turn the motor by hand? What comes to my mind is that when loaded with a sideways pulling force on the motor shaft, a bearing that may already be going bad is stopping the whole motor from turning.

Re: Modern History

Keep in mind that wood is most definitely not your only option. Ron has a beautiful tug built out of steel, and has an excellent website showing the process here: http://www.rogersmachine.net/steamboat8.html

Re: Burning corn as fuel?

Most of the successful corn burners I have seen in my research have relied on either forced draft, or some sort of agitator, or have burned coked corn instead. While these are all interesting possibilities, there's a coal mine a day's drive from my home that's willing to sell by the ton, and that wi...

Re: Burning corn as fuel?

I did some experiments with the idea over the weekend and the results were for the most part disappointing. I lit the fire with wood and slowly started to add the corn. At first it caught quite quickly and gave a lot of heat, however as the wood burned away the fire died down considerably. My best e...

Burning corn as fuel?

Okay, I know it sounds ridiculous but corn has been used for a long time as fuel in pellet stoves. It doesn't burn as cleanly as wood, but it comes pre-pelletized, has ~7000 BTUs per lb, and, at least here in Oklahoma, can be had for abut 8-9¢ per pound at the moment, and is available throughout the...

Pressure Washer Pumps for Feedwater

Howdy

Has anyone had any experience using pressure washer pumps as a feedwater pump? It seems like an inexpensive solution, but I'd love to hear if anyone else has experimented with it.

Re: steamboat Emerald

I will be calling him today. As far as cunifer/kunifer/and whatever else they call it. I've quite some trouble finding many suppliers in North America as well, though there seems to be more than just a few years ago. Here are a few: http://www.fedhillusa.com/ http://www.farmerscopper.com/copper-nic...

Re: Desuperheater question

Tom, "Out of curiosity, where can you access a copy of the ASME BPVC" You can buy it from the ASME, I think for a couple of thousand dollars for the whole set. The engineering firm I worked for (45 years so far) is certified to make unfired pressure vessels and boilers, and thus has full sets of AS...
