Confederation Marine Modellers

Roy started the proceedings by talking about the boat he's building with his 7-year old grandson. It is a small cabin cruiser based on a lifeboat design in Glynn Guest's book "Small radio control boats". Construction is very simple using only balsa for the hull. The superstructure will be styrene. Guest's designs are all for stand-off models of simple construction, and are an excellent intermediate step between building kits and complex plank-on-frame models.
Roy followed this with a demonstration of the use of small stepper motors to power radar scanners. In this case they are fitted to the wheelhouse and mast of Roy's catamaran ferry "Manannan". Stepper motors have the advantage that they are much smaller than the DC motors we typically use, but their disadvantage is that they are more complicated to set up. They require dedicated electronic 'drivers' as well as a microcontroller (such as Arduino) to feed the drivers.
Paul was next up with information about this Flower-class corvette, "La Malbaie", with some of his information described above. Of particular interest was the fact that Paul's father-in-law served on La Malbaie during WW2, for the whole of 1943. THe Royal Navy's corvettes were named after varieties of flower, but the RCN chose the names of towns in Canada. They often persuaded the towns to 'adopt' the vessels, and this commonly resulted in the townspeople sending comforts, such as clothing and food, to the crews.
Steve gave an update on the workshop progress on the Pilot 40 which is under construction. The process has evolved to one in which techniques are demonstrated at the workshop and then someone takes the model home to continue work on it.
The model is now ready for the propeller shafts to be locked in place and for fibreglassing of the hull to begin. Steve also showed us the motor mount that Doug has made specifically for the model.
Robert L. mentioned that he enjoyed participating in the display at the Home show. Although the traffic was light there was good interaction amongst the members participating.
During the business part of the meeting, Roy spoke about the "sail and scale" sessions that several members join on weekday mornings, typically between 8 and 11am at the Spencer's Pond.
