OTM Inc did a lot of work with the Northwest Seaport this week – both hammering and teaching. But first:
Control head for the Maris Pearl!

The Duwamish, completed!
Last week I finished rebuilding the Duwamish’s air compressor, but didn’t have time to test it. This week, I ran it for a few hours while I cleaned up the engine room a bit. It worked great! Before the rebuild, it basically didn’t work at all because the air compressor’s [...]

A visit to the Sakarissa

It’s a World War II tug (YTM-269), powered by a DMQ 8 Enterprise (serial number 41119). It has a new governor, a new seawater pump, and a Sperry steering system (with a few [...]

Reader Saúl emailed me for some Enterprise information:
Would you know where I can find an image of the logo placed by Enterprise Engines & Foundry on the armor parts they created during WWII? I am trying to update this list.

Back to business-as-usual
This week, I’ve gotten back in the shop. I worked on cleaning up an engine control station that I picked up recently. It’s a neat find, perfect for a direct-reversing twin-screw boat. After I finish cleaning it up, I’ll post pictures and put it up on eBay – hopefully by [...]

An update from the Duwamish
The Worthington Company (1-800-892-6189) does not have any parts for the fireboat Duwamish’s air compressor. They do stock a lot of parts for old air compressors, but this one is very old and rare. We’ve decided that the best option is to make new valves. One should be [...]

I’m still working on the air compressor for the fireboat, mostly searching for parts and slowly making new parts. I did find a company that still supplies parts for Worthington air compressors, who may have the parts we need.

An update from the John N Cobb
We hear that NOAA has decided to tow the John N Cobb back to Seattle before decommissioning the boat. This may give the engineers and mechanics a chance to determine the problem. All of us at the shop think the vibration dampener should be the first suspect [...]
