Re: Engine ready

In tooling we used rollers (cam followers) in a similar configuration on telescoping torque tubes. Rolling on mild steel wouldn't last long. They will displace the metal they ride upon much like an ''English wheel'' works and shapes sheet metal. We tried hardchroming the surface which didn't help. T...

Re: Stainless steel tubes

I very much like the "spin the turbulators" idea. I had planned on using them but will now go individuals rather than wire coil pairs. I sheared strips then twisted them. Then I welded on small rod and another short one at the top at 90 degrees to make a T handle. They really only need to be in the...

Re: Stainless steel tubes

I stopped and checked, they have a pile of cutoffs 20" to 7' in length. ASTM A53 1" sch 40 gr A F 2 Sch 40 A53 welded seam works just fine. Wall thickness within reason is irrelevant. I use SCh 40 A53 for Ofeldt watertube coils, it tolerates the winding process and holds up just fine. About six yea...

Reproduction? No, it isn't. An Original car restoration.

I laugh, steamboaters are generally nice and not judgemental, roll four wheels under something and it's ''cue the jerks''...

Pete,

Well, that's not good. I think with the whole plandemic, we're all having to make unwanted adjustments to the new world order. Don't be a stranger here, we all enjoy your postings.

Take care, Ron

Re: Bearer Material Selection

Another Opine. Just lagbolt to the hull about every four inches. Use marine bedding compound or Lifecaulk in between. Make them from white oak, Cypress or mahogany, then seal and paint with marine paint (porch paint). Sealing them with epoxy, once oil and water get in around the drilled holes, they'...

Re: Steam engine from the North Caucasus

Very good machine work. When I made the eccentrics for my Locomobile the keyway on the crankshaft is in line with the crank throw top dead center, if I remember correctly. The keyways in the eccentrics are set at 45 degrees to low lobe. Your engine timing may be different. It looks like you have a k...

Re: Need a 1" NPT Hoffman 1140-05 Valve BODY Unit ONLY

I found your other thread that shows the valve inside. I Would bore out the old seats and thread them, then make and install stainless seats. Stainless stem and valves also. Then bore out the valve guides and line with 932 bronze. With those tiny bronze contact area valves and seats it was never int...

Re: Need a 1" NPT Hoffman 1140-05 Valve BODY Unit ONLY

I'd get with someone who has pattern making and machining skills and have a new body cast and then machined. Go on some of the scale locomotive, or home shop machinist forums, this is routine for them. What about altering a 1'' whistle valve? Which is essentially a poppet valve My guess as to whats ...
