[Sentinel Resurrection...]

Thanks for the info on the spare parts, I'll give them a try.  Wasn't aware the original kit was plastci!

[HONLEY TANK:- The Machine Tools Still Work!]

When I was converting Lima diesels to P4 (all of 20+ years ago!) I turned the Lima brass wheels down and fitted Alan Gibson coach wheel tyres, removing the excess material from the wheel back up to the tyre rim and refitted them on the original Lima axles.  I found that only a thin spacer (20 thou?) was needed to maintain meshing.  On the gear fitted wheel a bit more care was necessary as the 'sprocket' is fitted right up to the back of the wheel - in fact, it may be moulded as part of the insulation, I can't remember now!

[Some Tricky Soldering]

The track assembly tools sold by Studiolith in the early days of P4 were made from modified hair grips with various width shims added for correct width clearances for blades etc.  Very useful items for the tool box!
