Odd Jobs

Tuesday 12th Dec

A bit thin on the ground today with only three of us in action at Winchcombe.
It was a question of how many uses can you find for point rodding!
As reported previously we had cut up two of our 18ft lengths into 7" lengths for mounting the signal wire rollers along the platforms at Broadway - that was enough for one platform - we now need another similar quantity. So this kept us warm with the angle grinder and file. John P in action cutting :

And clearing the outside bench ready for filing off the burrs (we don't let a bit of inclement weather get in the way - just have to hope we don't lose any of the cut - offs in the snow!)

And here's the completed pile ready for drilling. A total of 58 from the two lengths plus 3 more from a short piece found under the bench

Oh for the new workshop!

The next use for bits of rodding is for clamps to mount a warning sign to a post at the crossing at the rear of C & W at Winchcombe. This post had suffered a recent "dislodging" so the opportunity has been taken to give the sign a face-lift with fresh paint - the white gloss needed a steady hand

And here are the rodding clamps at the rear

Then off outside to the post

And finally mounted. A bit of touch - up painting required on the post.

I did manage to put a coat of silver paint on the new "shoe box" lineside  cabinet opposite the signal box. Not the best of days to be painting outside but it appears to be OK

And now for the technical bit that I would like to share with you. I did say in the last blog that I would get a picture of a point rodding compensator - so here goes (those of you with a nervous technical disposition look away now)
This first picture shows the compensator as it is set initially with its two arms at right angles to the rodding - ideally on an average temperature day

The compensator is positioned at the centre of the rodding run between the signal box and point. This means that on a hot day both lengths of the rodding will expand equally pushing the arms of the compensator inwards as shown here

The two arms of the compensator cannot move independently from each other so the point can still be operated in the normal manner. 
Conversely, on a cold day contraction of the rodding gives us the following :

This cunning system prevents  unwanted point movement with extreme changes of temperature. 
It is the same problem experienced with long runs of signal wire (see a previous blog) 

Hope it gets a bit warmer for our last working day  (next Tuesday) before  Christmas 



  1. Don't think I would have fancied cutting the rodding 'bits' in what looks like sub zero temperatures! Well done to those who did! At Highley, the S&T took over one of our station rooms for activities in winter, with a coal fire of course! Regards, Paul.

  2. You've got to take your hat off to the person who first thought of the idea of that compensator! Genius. I guess it does require all the run of rodding to be subject to the same temperature variations though - some of it out in the sunshine and the rest in shadow might cause a bit of a problem.

  3. What a team! Out in all weathers the unseen hero's of the line. Now lets not let allow legal people in on the compensator story or they could get easily confused!!! Lets hope the weather improves for your next outing.
