That IP doesn't look bad at all Barry. Shame about the Eduard set. I have found similar problems with coloured PE seat belts. The instructions say bend but then the coloured layer just cracks off.
That’s coming on well Barry, looks excellent so far.A quick one. I measured our 60grams of liquid gravity into a shot glass and balanced that on the nose!

Perfect. I now know how much I need to use. A bit too much to fit into the nose itself (as Trumpy suggest) but it clearly works a bit further back.
Yes Tim, thanks. I am aware. I positioned it there because the instructions say 60gms in the nose cone but there is not really enough room, hence trying it a little further back, where I did.That’s coming on well Barry, looks excellent so far.
Just remember that as you move the weight back towards the pivot point the turning moment is decreased and you need more weight to generate the same effect Barry. That shot glass is right on the extremity so is exerting the most it can.
It works like this….

Don’t want to tell you how to suck eggs, but also did want you to zip it all up and find she won’t balance, especially after all this great work you’ve put in.
If you do use genuine lead shot Andrew don’t glue it in with PVA. If you do it turns into Lead acetate, which expands and can crack joints over time. Used to be a common issue amongst loco builders back in the nineties.Coming on nicely Barry.
That liquid gravity looks just like the very smallest lead shot I used for fishing not that I do much... Last time I checked shot size 8 and below could still be lead and I still have some in the fishing box.
Will be interesting to work out which is cheaper....a premium modelling product or cheap lead shot....
