I am going to peruse the archives on this, but thought I would ask right off the top. I am going to install my first tortoises today, through 2" of foam plus 1/4 to 1/2" of plywood (depending on location in benchwork) to activate the various Shinohara curved switches on my expansion. I see the instructions say to drill a 1/4" hole for the throwing motion of the wire.  Should I increase this diameter if going through the thicker base like mine, or make it more of a slot? I have the correct longer wire to use for an extension. I have to cut away the roadbed under the tiebar.  But I was wondering if it is possible or advisable to cut away some of the long ends of the tie bar on these Shinohara switches, since I will be using the hole in the middle for activation.  Are the longer ends typical in reality, or no?  They would seem to stick out quite a bit past the cork roadbed, but may be a good idea for the travel of the tie bar? <img sab="884" src="http://i168.photobucket.com/albums/u172/dcrane_2007/shinohara-1.jpg" border="0" style="max-width: 550px;" />   And any other tips on this sort of application would be appreciated before I start in.  Thanks. Oh, and this is more of an electronics thread ques.  I see I would not be using the current through my Circuitron Snapper capacitor discharge unit to power the tortoises, I guess.  Seems they need just a regular low voltage transfomer ?
