After you add the penthouse apartment floor at the top for the elves, will it still fit through that door?

They prefer a nest like squirrels make, but they use steel wool rather than leaves.   :Lol:

I don't have a boiler that would be suitable for this engine, unless I tapped into the Lombard or Mann engine. Am planning just to run it on compressed air. I'll hide air lines direct to the other two cylinders, with needle valves to balance the flows, in the receiver tanks between the cylinders. To keep it looking interesting I may leave off some or all of the lagging on the cylinder level, it makes the engine look like an apartment block (for elves) with all the lagging panels in place. These engines ran slow, in the 12 to 20 rpm range, so hopefully with the large flywheels it will purr along.

The cylinder blocks are going to be interesting to make on the Sherlines, have found some automotive cylinder liners that I will use for the core of the IP and LP cylinders, which would otherwise be tough to turn on a 3" lathe (LP piston is 3" diameter). Thinking of stacking up some plate stock to form the outer jacket for the cylinders, the top/bottom sections were made seperately anyway, with the valves inside them - Corliss on HP/IP, poppet on LP. Thats a ways off though!  Maybe by then I'll find a 1" cylinder liner that will work, have not found one long enough yet, 2-3/8",  without ports in the side. That one could be turned normally though.

Even if it's to create some "castings".....everything roughed out and you finish it on the Sherline.

Isn't the old movie quote something like 'I know a guy who knows a guy who killed a guy...' ?   :Lol:

A friend of mine with a small manufacturing business locally has a humongo lathe, it can take 18" parts through the headstock, which means he could chuck up my lathe and mill, has offered its use anytime for turning/shaping large parts, though I'd be looking around on the cross slide asking 'wheres the lathe?' !! My lathe got carried down the hall to the shop room. His got delivered by huge truck and a crew of riggers - wish I had pictures of it going in!

The Holly build is going to be on hold for several days, my cousin is bringing over some fittings from one of the old mahogany Chris-Craft powerboats he has that need to be remade. Castings that metal fatigued and broke, no replacements available, so I am going to duplicate in stainless bar stock. Will be back on the Holly sometime next week.

I'd be interested in some posts about that process. I'm sure you'll do it creatively, artistically, well-engineeredly, and fast.

But I don't want you to waste time away from the Holly, either, I'm spellbound following that......

Good heavens! I've not been on the forum so much lately, so I'm just getting caught up with builds, and I had 4 pages to get through on this one - absolutely amazing - really great to see those frames come together. Brilliant techniques, and the result just speaks for itself. Top shelf as always!
