May, 2010 MEETING - in case you missed it

 

DAVE BRAY brought in brass side tanks for his 4 ¾” gauge Dougal. He explained that this was a cheaper option than importing the aluminum castings. The top ends and bottom of the tanks are from 1/8” thick brass soldered together using a low silver content soft solder. This solder had a higher melting point than the soft solder so wouldn’t soften while soldering with the soft solder. The sides from 1/16” brass were soldered to the ends, top and bottom using regular soft solder.  Both tanks have outlets to the axle pump, one tank inlet overflow from the axle pump bypass, the other outlet to the hand pump. Dave asked for suggestions for painting preparation: answer – use a self etching primer available from CTC or Sherwin Williams automotive paints.

 

GERRY REED talked about rope knots and their usefulness. He demonstrated a simple “thumb” knot and how by improvising its application, it can be used to safely lift a fair size object. Gerry suggested all members bring in a 10 to 12ft length of 5/16” sash cord to the next meeting and he will have us make our own knots under his instructions.

 

DON CARR has been grappling with the axle boxes for his Joslin Hudson locomotive. He made his own patterns and had them cast, with some difficulty, by the Scara foundry in Mississauga. The first set of casting had to be scrapped – too much porosity. Don explained how he found the 9D aluminum bronze  extremely difficult to machine however, after much perseverance, Don succeeded mainly by surface grinding. He also showed how he used jacking bolts tapped into the block plates to lift them from the magnetic chuck of the grinder.

 

DAVE POWELL & ERIC MOTTON demonstrated boiler hydrotests, initially on Eric’s copper boiler for his 4-6-2 LMS Duchess class loco, tested at 135psi (1 ½ times operating pressure). Then Dave’s steel boiler (with expanded copper tubes) for his 4-6-4 (maybe?) loco, tested at 250psi (but only required to go to150psi)for a 100psi operating pressure. Dave and Eric emphasized the need to make sure ALL air is out of the boiler before pumping up. The stored energy of compressed air can do serious damage in the event of a major failure.

 

HELMUT HEINZINGER showed several pictures of his home built vertical bandsaw with 2 speed drive. It is designed for ¼” saw blades although Helmut says he may be able to use 3/8” alternatively. Most of the platework is from ½” aluminum which Helmut was able to find. The saw assembly stands about 4ft high and site on a 2ft high stand. The throat is 10” with a height access of about 7”.

 

ROBERT WYSS has pictures of a 1/6th scale 1932 SJ Duisenberg in minute detail made by Lou Chenot that has taken him some 17 years to complete. Apparently he was not satisfied or could find any chroming outfit to do the very small parts so made his own set up in his home! The detail is quite amazing to see.

 

Thanks to Dave Bray for taking the meeting notes.

DRILL PRESS:
 A tall upright machine useful for suddenly snatching flat metal bar  stock out of your hands so that it smacks you in the chest and flings  your beer across the room, denting the freshly-painted project which you  had carefully set in the corner where nothing could get to it.

WIRE WHEEL:
Cleans paint off bolts and then throws them somewhere under the workbench with the speed of light. Also removes fingerprints and hard-earned calluses from fingers in about the time it takes you to say, "Oh, s....!"
