I am becoming slightly obsessed with the Hornby Ruston 48DS chassis, to the extent that I'm now looking at a number of other things I might be able to fit it under. Suggestions welcome! 

Last night I was too tired to do any proper modelling, so I had a mess around with my Howard/Hibberd/Planet CAD, and it looks like the Ruston could be made to fit. The wheels are a little bit too small, but reasonably well hidden on this loco, and the bonnet would have to be made about 2mm wider. I'm still debating whether this is an acceptable compromise - it would run much better than its current chassis.

I'm also having a go at semi-freelancing another... thing - I'm not going to reveal what it's based on yet, as there's a good chance it won't work. It is very small though!

Stats:

Time spent on CAD instead of sleep: too much

Hours before I have to go back to work (hooray!): 100(ish)

Cumulative pushup counter: 1690 (ow!)
