Fen End Pit - point levers


Fen End Pit

The original point levers on Fen End Pit were of the simple lever type. I made each one by hand out of plasticard, each one taking 20 individual parts to be cut, shaped and stuck together. The results looked pretty good.

However most of the preserved railways I've visited tend to have the rather more complex type which have a weighted lever that throws parallel with the track. This example is at Launceston on the Launceston Steam Railway.

I spent a few happy hours in CAD modelling up the lever and produced this drawing.

This is not designed to be functional, so I printed it in three parts, the base including the swinging crank, the lever arm and the round weight. Breaking models up to make the parts print better it part of the things that I'm learning about this 3D printing lark. I pretty happy with the result for a first attempt, I think need to adjust the proportions slightly but it's not a bad start.
