TSME CHAT LINE: tsme@yahoogroups.com
Please don’t let this long and snowy winter bother you! Just think of all the time that this has given you to spend time on your projects (well, that’s after shoveling the driveway for the ‘nth’ time!). Come and join your fellow members, and forget about the weather, at our next meeting which will be on …….
FRIDAY 11 APRIL 2008 AT 8.00pm - 1001 QUEEN STREET WEST
IN THIS EVENING’S PROGRAM YOU CAN EXPECT TO HEAR FROM:
ERIC MOTTON has a winch project he will talk about,
DON CARR has a bending roll he would like to show and explain,
DAVE OULTON has a Rotary Table and a Power Feed for his Mill he wishes to talk about.
The club members would like to see models, or in progress of being built, that have not previously been shown. You do not have to talk about the item, if you prefer not to. We would just like to see it.
WHAT’S UP & COMING : MEETING DATES: 11 April, 9 May, 13 June @ 1001 Queen Street.
The remaining contents of JOHN NICOLAIDES’ shop will be for sale/auction at the house, on 26 April.
MARCH 2008 MEETING - IN CASE YOU MISSED IT, (Many thanks to Geoff Kingma for taking these notes)
The meeting opened with BILL SALT showed the tender of his ¼ scale “Little Sampson” traction engine and the work he has done on it so far. He described how he rough cut the brass plate and then filed to the “line” with the aid of a steel reference edge. To bend the metal for the rear section he made a wood pattern and formed the metal to the correct radius. He also brought in the brake band and described how he made that part as well as how he used his mill instead of a shaper to make the diamond chequered plate. He also mentioned how expensive brass sheet has become.
SCOTT BARRIE showed the movie of TSME’s history that he has compiled. The interviews with long standing current members and their comments on the Club’s history and its past members were very interesting. The archival items that Scott was able to incorporate into the presentation certainly brings to life the 75 years of the Club’s history. Many thanks for your efforts.
DAVE POWELL demonstrated, via video, the technique he used in his workshop to cut the teeth for model steam engine lubricator ratchet wheels. He set up a 5C spin indexer on the table of his shaper, a stop system for the down feed and was able to cut, then index, without stopping the shaper. As the indexer had 36 holes, he decided that the ratchet wheels would have the same number of teeth. Thanks to Dave Oulton for taking the photos and video.
ALEX BARRIE brought the ram section of his 1/3 scale Ammco shaper and described how he machined the part so far. He is using Meehanite (continuous cast iron bar stock) to make the part but, by using a vacuum as he was machining it, he was able to control the dust. We look forward to seeing this project progress.
DAVE BOWES brought in an EVIC engine made by Bud, a modeler from NJ, who modified a Magnum XC91 (using the original rockers) to take the solenoid valve system designed by Dave. He asked Dave to see if he could get it running as he was having some problems. Dave found that he had to reverse the solenoid polarity and drained the crank of oil as the single piston ring could not prevent the oil from fouling the plug. Using a 2% oil in gasoline mix the engine was successfully run and Dave was able to get it to operate on a hit ‘n miss cycle at 900 and 1100 rpm as Bud had wanted.
Dave also mentioned that he is working on a Mark 3 Evic engine (turning a 14” prop) that will be mounted in a model of a Beaver aeroplane. A weight reduction exercise for the engine is underway!
ANDY WOJTECZKO discussed the work he and his son are doing on a Lexus for the “Speed World Challenge” auto racing program. Taking a bare-bones body, they install suspension, drive train and engine. Most of the components are made in his shop and he uses Solidworks to design the parts. He brought in some of the items along with the clutch, throttle and brake pedals. Light weight but enough strength are key.
The final presenter, DAVE SAGE, showed the progress to date of the V8 engine he is building based on the Jerry Howell designed V4. After ordering the plans for the V4, he designed a new crankshaft and cylinder block on a Cad program. The crank (built up design) and partially machined block were shown along with a jig to hold
the block in position for the various operations. Dave is making the crank to a conventional V8 firing
order but maintaining the existing design of connecting rod (Harley Davidson style) so the cylinders will not
have to be offset.
A LETTER TO MODEL ENGINEERING:
The following as an abbreviated version of a letter that JOHN CHAPPELL has just sent to Post Bag at Model Engineering Magazine, about young members:
As TSME adds to it s 75 years, orientation of our program needs updating. We are lucky to have members like Kyle who describes his electronic exhibits so well. This trend toward robotics etc. should be noted by those who grew up with steam shovels that had chains, shafts and gears to see. Also we saw bridges of lattice construction so their bracing was obvious. Hydraulic digger models could be exploited by old-timers to advantage to enthuse the tyro showing him something that “looks-real”, and that could be controlled perhaps by multiple hoses with the pressure built up at the control point. Another project already made by members Buck & Dan. is of controlled robots that can interview people by a hidden operator. So model engineers don’t have to have a background of Meccano, “toy” steam engines, and clock-work trains to be interested in modern things.
