Whats the point? installation

Posted by RichardW1 , 02 February 2013 · 704 views

The Servo motors arrived this week, and to my great surprise the Servo4 board and Setting box worked flawlessly. A simple support cradle was swiftly assembled this morning from offcuts of ABS sheet. When assembled, the complete unit was mated with the turnout, and in-situ testing started.

Unfortunately the turnout would not fully throw in one direction. A bit of discreet measurement showed that addition of all the working tolerances meant that the pivot point for the lever arm, was too close to the pin guide. A new pivot was quickly drilled and tapped, and the unit reassembled. This now works fine.

Now that the trial design has been shown to work satisfactorily, I guess I shall be banished to the workshop to manufacture the remaining three units to enable the turnouts on Maxstoke to all be fullt operational- who knows, I may even get the mechanical aspects of the layout completed by Easter!
