I'm working on something a bit technical. My friend has dropped round a Hornby Merchant Navy class loco to repair . My friends layout is as smooth as a ploughed field. :ohmy:. It would be no problem for the old Triang or metal bodied Hornby locos but not very good for the highly detailed modern stuff. It seems as there is too much sideways play on the driving wheel axles allowing them to go sideways willy nilly! When one axle decides to go one way and another the other the connecting rods don't seem to like it and get all tangled up . I am trying to straighten one connecting rod at the moment . I have got it straight in one plane , it needs straightening bin the other now . I'm wondering if the axles could be shimmed with plastic washers to take up some slack or would it mean that it won't go round bends very well ?
There should be some play, but nothing excessive, which allows for uneven track laying.

Has he been running it on a tighter curve than it's supposed to be run on.

Do you know the "R" number, if not that, the name of the loco. Don't bin anything yet, you may be able to put them back on, avoiding paying for replacement parts which may get damaged if all the axles aren't turning in the same direction.

"Heavy hands" are the biggest source of damage to the running gear. Slowly moving them until they catch on something whilst moving.

Anyways, I have a nice :cuppa: and the world is a much better place as a result.

She'd either need a decent extension lead, or a portable gas stove, to boil a kettle in a field.

Were/are you certain it was 400 sheep.
I had seventy minutes to work on the sheep census problem. I started with the sheep to the far left and drew an imaginary vertical line (cursor). Moving left to right, I counted every sheep that the cursor encountered. That was easy with the sheep in the left side of the field because they were close to me but it got increasingly difficult as the sample stretched further and further into the distance. Besides, the little buggers tended to move about. In the end, I took the data from the first 20% of my left to right scan and "eyeballed" it into a "one eye closed" estimate of sheep density in the whole field. It's an entirely valid technique used by all statisticians:whistle:

Yes, it was a very long seventy minutes.

Easier if you work front to back/back to front rather than side to side.

And you were still awake at the end of the seventy minutes? I'm impressed... :tongue:
