HAVE I GOT A PISTON!!,

Recommended Posts

D-17_Dave
There's one at the Smithsonian that's about 35' in dia. and the rod spans from the piston down to the lower floor. It came out of a ship engine. The piston is that section of floor. It's awsome. Anyone who hasn't had the opertunity to visit our nations capital and see our mech. treasures has missed an oppertunity of a lifetime. It's well wourth the trip.

I worked at a place that some air compressors that had pistons about 48" diameter. Some of you have seen the connecting rod from one in my yard, it's about 6' long...

Used to work on natural gas compressors in Texas. The machines were made in the 30's. We would stand on the crankshaft inside the cylinders to inspect the ports(2 stroke). Bet they're still pushing gas from Texas toward Tennessee. If you weld two of those together, skirt to skirt, maybe you could sell them at the shows as lawn rollers!

Hmmmm looks like it is out of an old White Superior engine....mabye Fairbanks Morse. Seen a lot of these on old 40's-50's era 400Kw stationary sets....inline 8 cylinder..run about 700 rpms best of my memory. I worked on several Cooper Bessmer and EMD 4Mw sets that had very large components....will try to find some pics and post. The Cooper Bessmer turbos were big as a Volkswagen and each head (1 per cylinder) weighed 6000 lbs. Ike

You can see a lot of the machines in use on saturday mornings, where a curator will give you a tour and operate the machines. JH

I've seen the two-story-tall piston and connecting rod, taken from the NYC subway (I believe) at the Smithsonian. D-17 Dave has it right about that museum being amazing. I think it was in the "American History" building of the Smithsonian, but it's been awhile. I didn't know about the Saturday tours and running machines--thanks! We're planning to go again someday--I've been a few times and you can never get enough!
