Giant 22+ TON Engine (START UP) (circa 1920)

Published on Apr 21, 2012 by taofledermaus
Originally thought this was a "hit and miss" type engine because of the flywheel configuration, but after some research learned it is a 2 stroke diesel engine.

Story of this massive engine.
This is a 110 HP 2 cycle 2 cylinder hot head oil engine manufactured by the Continental Gin Company in Birmingham, Alabama. This engine was located in Yuma, Arizona, and was in use at a cotton gin from 1924 to 1949. Since this engine has no load on it, it is pretty quiet, but folks said when it was in service and under load, it could be heard for over 12 miles. It is started using compressed air and both of the hot heads are heated using torches, though I did not notice that when they started this.

Interesting Specs:
The weight of this beast is over 22 tons.
Each flywheel weighs 4260 lbs.
Bore is 14"
Stroke is 20"
It runs on a mixture of oil and diesel.
RPM 225

This was at the Antique Farm Equipment Show in Tulare, CA.

Antique Bulldozers and Crawlers

Published on Apr 22, 2012 by taofledermaus
A large collection of vintage and antique crawlers. Many were unrestored and look like they should not even run, while others have been restored and look like they just rolled out of the factory. Bulldozers have a scraping blade on the front, while others are simply called "crawlers" or tracted-tractors.

HOW to Identify, Prevent, and Control Oak Wilt

Title: How To Identify, Prevent, and Control Oak Wilt
Author: O'Brien, Joseph; Mielke, Manfred; Starkey, Dale; Juzwik, Jennifer

Year: 2011

Publication: USDA Forest Service, Department of Agriculture, Northeastern Area, State & Private Forestry, NA-FR-01-11

Abstract: Oak wilt is an aggressive disease that affects many species of oak (Quercus spp.). It is one of the most serious tree diseases in the eastern United States, killing thousands of oaks each year in forests, woodlots, and home landscapes.

Oak wilt was first identified in 1944. The fungal pathogen that causes the disease, Ceratocystis fagacearum, is thought by most to be native to the eastern United States, but difficulty in isolating and identifying the fungus delayed recognition of the extent of its impact until the 1980's. Some plant pathologists think that oak wilt is an exotic disease, arriving in North America in the early 1900's, but the fungus has never been reported from any country other than the United States. The disease has also become much more apparent in some local areas since the 1980's because of increased tree wounding, due primarily to home construction in oak woods.

The milling process is beginning with the pines for the roof. Doug and I also worked with a miller when we built our timber frame barn. We milled a stand of oaks killed by oak wilt for the roof boards of the barn. Doug and I spent two very physical days lifting each inch-thick oak plank off the mill and stacking them. Each cut revealed grain more beautiful than the last. It was like going to an art gallery of wood.
