IN CASE YOU MISSED IT – THE SEPTEMBER MEETING
DAVE BRAY was awarded the Herb Jordan award (much to his surprise ! – Ed)
DAVE SAGE showed the telescope he adapted for photographing the eclipse of the moon in Feb 1988 and since, eclipses of both sun and moon. The camera must be firm and solid. The drive is by stepper motor mathematically calculated to compensate for planet movement. Manual drive can override this by clutches. Dave showed a photo taken of stars – a 15 minute exposure.
ANDY WOJTECZKO made a Tube Notcher for joining tubing at any set angle for his race car chassis. Tubing he is working with is 1 ¾” OD and a metal keyhole saw is used to cut the tube end profile,
DON CARR talked about his approach to machining Deep Narrow Slots for loco spring hangers and split connecting rod ends. He found that direct cutting with a cutter wheel didn’t work the wheel often jamming. Don now uses a keyhole saw to rough cut and finishes with the cutter wheel.
ROBERT WYSS said that the “Iron Fever” show earlier this summer was a disappointment, so showed slides of this years NAMES at Wyandotte,
TIM HILL showed his half size OVER Crank Engine running nicely on air. The plans came from Live Steam Magazine. Tim also showed a Double Acting Engine with square cylinders made from Lego.
DAVE POWELL showed his second 3 ½” gauge Caribou which he recently acquired. He is presently reconditioning the cylinders and motion. The boiler and tender are all ready. Dave hopes that he can have it running this year.
REMO COSOLO showed a knurling tool for use with the drill press he had made some time ago. It is a “squeeze” type which applies the knurling load be hand and puts little stress on the work or the drill,
DAN O’CONNELL brought in his “Make my Day” spinner type radio controlled combative Robot. It was circular about 18” dia by 3” high, driven be two motors and weighed in at about 30lbs. Don explained the difficulties he is having at the moment with the failsafe features which are needed in case the robot disobeys and takes off. Its combative feature is a rotating arm with vertical down facing vertical cutters rotating at 1800rpm – some weapon!
JIM SMALL talked about broaching and how best to do this in your home workshop: Good for cutting straight slots. The broach is pushed through, cutting about 1/16” each pass. A hydraulic press is needed for this process, a hand press would not provide the power required.
JOHN CHAPPELL first wished to say how impressed he is with improvements in the Model Engineer Magazine recently. John also showed his small (1/8”) square broaches her used for handwheel centres. He also explained his process for making leather cup washers. He emphasized the need to plan your work first. Use a former for the water soaked leather and leave it in the former overnight. Trim with a Dremel. Old leather gloves make for good washers, but the outside surface needs to be smooth for good sealing. Fit the washer – and oil well..
