27th Febuary 2005 Mark has been slowly making progress, here's a log of the last few weeks: 19/2/2005 Got fishing line, eye hooks and lead weights for turnout control. 21/2/2005 Caravan chassis sold for $200 on ebay. 22/2/05 Drilled 3 holes for turnout actuation. 24/02/05 Installed 3 tie bars. 27/02/05 Installed blades and tie bars on complex track formation at Graytown, except for the double compound which still needs a few blades made. Now considering using the Joe Fugate method of turnout actuation which uses a piece of spring steel wire to both return the blades to normal and project through the road bed to move the tie bar. I hope to move the fishing line by using ex Telecom key switches. As these switches have a hole below the pivot point I have to do one of the following to get the movement I want:
The complex track formation needs some logic in the blade actuation that dictates that most will be electrically controlled. Mark |
