Manually controlled turnout using a "over center spring". |
Tim Warris from Fast Tracks shows how to make an over center spring for your turnout.
The turnout was milled from a solid piece of PC board with holding taps. |
First it was drawn up on Draft Sight CAD program. A free very powerful 2D CAD program. The red line is for the cutter path. |
The CAD drawing was then imported into the CAM program that is used to generate the tool path and the G-code. |
The G-code has been generated and some manual programming is done. The G-code is then input to the computer that runs the mill. |
A PC turnout board being milled. |
Both left hand and right hand turnouts were made using the same cad drawing. By flipping the drawing you can mill out the other hand turnout. |
A frog fixture was made to properly and accurately assemble the frog. A piece of Rock Maple was used. |
To get the proper angle a fixture was made to hold the rail for grinding on the Sherline lathe. |
