Re: Boat paint

When I was a kid we used to use "red lead primer" (probably explains a few things) quite a bit working on old boats. We used it under bottom paint mostly, or "bottom copper". That is probably what the bilges are painted with. Yeah I'd wear a respirator, if you're sanding it. Should wear a respirator...

Re: Desuperheater question

I run an Ofeldt in my carriage with economizer and superheater, the economizer or any feedwater heater is much more important, some of the navy ships had as many as five feedwater heaters. A Feedwater heater (Mike are you reading this :) ) is far more critical in it's design and necessary. I have tw...

Re: Opposed Piston Engine Project - The Steam Version

Someone was talking about an engine like this a while back on the Steam car forum. There is some misconception that, the cranks will split the loading that is normally on one crank, not true, there will be two cranks with equal loading and and the same as one, and there are some disadvantages mechan...

Re: Hello from Massachusetts!

I always use 303 Stainless for valve and piston rods, with never any adverse effects. Graphite flax packing. Also lubrication I opt to not use sight glasses with checkballs in them. Opting to just open the upper and lower valves enough to maintain flow. I was at a steam boat meet and one of the boat...

If I remember correctly, the canopy was a light tubular frame in the conventional shape of steam launch canopies. It hod a cut out for the boile...

Re: Marina Difficulties?

That is a real simple one, stay away from fuel docks with an open fire. No need for a woodfired boat to approach one anyway. There are other places to tie off and walk to the fuel dock if needed. I was waved in to one once because the marina owner wanted his visiting family to see the boat and I rel...

Re: Let's ban Loctite!

Agree with Jack on this, Loctite should never be used for crankshaft assembly. Loc-tite is a great product when used as intended, thread locker and a bearing seat. It was never intended to be used as an adhesive for structural components. I see these folks on YouTube "gluing" model steam engines tog...

Re: Con-rods and length

Quote: "Once properly understood (and trained) MiG is easy, and efficient." Yes it's definitely easy to lay down a bead, but it's a questionable weld due to the penetration issues. Sheer mass of the part can affect the penetration as localized temperatures of the material can often not be easily cha...
