Judging from the square spindle and setscrew I'd guess some kind of mortise passage lock. How about another clue.

Very nice bit of turning, Jay. Is that rosewood? Did you make the metal parts also?

Right handed gronicle crusher??:D Nice turnings Jay:cool:

[Bob Smalser]

Classy.

The shanks were turned out of 1 1/8" Navy Brass bar stock. The holes were broached 1/4" square. The wood is Cocobolo. Clue for you; they won't get very hot.

Valve handles on a boiler and/or steam engine?

Right you are! They are the handles for the blow down valves.

[Jim Ledger]

That would have been my next guess.;) Blow down handles, of course.

Very nicely done, Jay.

BTW have you got any pictures of the whole boat. There must be a story there, eh?

[Jay Greer]

Here are a few pictures of the boat. It is 15'loa beam5' and was built in 1931 as a life boat for a BC Ferry. Origionaly it was rated to carry nine passangers. The specs were carved into the stem.

Being a novice to such things, I'd be interested in hearing a little about the steam engine. How long from a dead start to get the steam up and get underway? What fuel do you use? What is the range? Is there a hp equivalent for the power output? Etc.

Beautiful job with the knobs.

[Jay Greer]

The owner tells me that it takes about ten minutes to get up a head of steam that is enough to get under way. The boiler runs on #2 diesel that heats the water in coils of copper tubing. These coils, by expansion and contraction, prevent scale from forming in the tubes.
The Canadian two cylinder compound engine provides about 8http://www.imagestation.com/picture/sraid225/p78c40515792f1db36d82f20a29edc8f6/e88a197a.jpg hp. When running, each piston works by double action. steam is let into the cylinder at the end of each stroke making each stroke a power stroke. Steam is then exhausted from the smaller cylinder in to the larger one essentially making the engine have the action of a four cylinder engine in operation.

More pictures of that boat please! :D

The boiler looks like a three drum watertube Blackstaffe-type. Is that correct?
Or does that sheet metal cover hide some other design?

[Tom Robb]

I love it when you guys talk dirty....:D

You know your boilers. It is a Blackstaffe.
