Abrasive Belt Machine

Converts To Other Tools

Circle 228 on Reader Service Card

Dynabrade's new kit includes the tool itself, contact arm, and parts to quickly convert the Dynafile II to a die grinder or 2-inch disc sander.

The Dynafile® II air-powered abrasive belt machine performs grinding, deburring, polishing and sanding of virtually any material used in manufacturing. The tool accepts six inter- changeable contact arms for many different applications including entering small openings.

Grinding work is done where the abrasive belt runs over the contact wheel and deburring/fin- ishing is accomplished by working over a platen mounted on the contact arm.

New kits are available which include the tool itself, contact arms, and parts to quickly convert the Dynafile II to a die grinder or 2-inch disc sander.

Tool features include quick and easy changing of abrasive belts and contact arm, lever throttle and choice of three motor styles. As an added feature, the air motor can be rotated and locked in position for work at virtually any angle.

Fairbanks Morse Offers

Free Literature Detailing

Blower Bypass Systems

The Fairbanks Morse Engine Division of Colt

Industries, Beloit, Wise., is offering a free copy of its color brochure detailing a blower bypass system for Fairbanks Morse blower scavenged opposed piston engines.

The four-page brochure, File No. 3090, de- scribes expected engine performance using the blower bypass system for blower scavenged opposed piston engines.

According to the publication, the blower by- pass system increases exhaust temperature at low load to significantly reduce or eliminate wet oil in the exhaust stack. The unit may be installed on old style, slope-side blowers, as well as on all new styles on both standard and reverse rotation engines.

The brochure uses several graphs, as well as configuration drawings to demonstrate engine performance with and without the blower by- pass system.

MARCO-Seattle To Build

Two Alaskan Longliners

Circle 245 on Reader Service Card

Drawing of the newly designed MARCO Shipyard 135-foot freezer longliner.

MARCO-Seattle shipyard has signed a con- tract to build two new 135-foot steel freezer longliners for Alaska Frontier Co. of Seattle,


With the continuing "Americanization" of

North Pacific fisheries under provisions of the

Magnuson Act, the larger foreign longliners are being taken out of the fishery. Historically, the

Alaska longline fishery has been based on small- er "ice boats." Now, however, there is a trend toward larger (130- to 150-foot) freezer longlin- ers, which head, gut, and freeze the fish on board. The new MARCO boats are designed to meet this growing need. "This is an especially gratifying opportunity," commented MARCO vice president Bob

McMahon. "We've been developing this new design over the past couple of years as the situa- tion in the North Pacific has been evolving, and now it's time has come."

The new MARCO design is a house-aft config- uration with a full-length shelter deck. The ship's fish-processing capacity will be approxi- mately 34,000 pounds per day, using horizontal plate freezers to produce blocks that will be kept in refrigerated dry holds for delivery to port or transshipment.

The 14,000-cubic-foot (400 nvO fish holds will have a capacity of about 560,000 pounds (254 mt). In addition, there will be a 1,000-cubic-foot refrigerated bait hold aboard.

The Alaska Frontier vessels will have com- plete MARCO automatic longline systems, fea- turing the CircleMatic baiting and setting ma- chine that automatically baits full-circle circle hooks. Also included will be the MarcoMatic hauler/coiler and the efficient MARCO rack storage system.

Operated with a crew of up to 21, the new longliners will be powered by Caterpillar 3512 diesel engines, rated at 1,175 hp, driving 86- inch, three-bladed CP propellers. Auxiliary power will be supplied by two Caterpillar 3406T gensets with 250-kw generators.

The new construction project follows con- tracts for three major conversions at the MAR-

CO yard. The yard has completed work on the

Westward Wind and Alaskan Command, and at present, is converting the Resolute. The yard also recently completed the installation of a new two-level pilothouse on the 108-foot MARCO crabber Norseman II, originally built in 1979.

The contract for the two Alaska Frontier new- buildings calls for August and October 1989 deliveries.
