Any body thought about doing a cab replacement moulding to make a 377 out of a Farish 168 using this technology?

Dr Deltic, you have mentionned one of my magic railway numbers i.e. 377  :D

If of value, the link below is to an OO Site where an Electrostar has been built (you have to scroll down to the bottom to get the start). If you do get around to making one, then I'd be interested in seeing the progress.

Looks really good. Not quite what I could leave in the model station car park (the model thieves would nick it ;) ).

I came to the conclusion that if one had gone to the trouble of designing the 375/7 etc cabs then you might as well just 3D print the lot (and cast bits) rather than trying to hack up turbostar bodies.

I will get round to it at some point, but I need to finish the crane first (after DEMU's Showcase exhibition is out of the way) and then decide what comes next.  An electrostar would be more use to me but an APT is very tempting!

Cheers, Mike

A 92 on the Farish 60 chassis is another obvious one.

Agreed on the bodies extruding a bodyshell from a profile is the easy bit - the ends are all the fun stuff.

Sorry to the guy that tried to buy my MK3 Lamps. 
Good thing they help by sending pics and info of what's wrong..
It looks like my model shrank on the server. Or they've changed their rules about thin areas since mine was printed.

Quote from:
    N Gauge MK3 Lamps 0.1 in Frosted Ultra Detail
    Reason: Thin walls
    Additional information: Wire thickness should be at least 0.6 mm for supported wires, 0.8 for free wires and 1.0mm for supporting wires and sprues.

Oh Shapeways and the moving goal posts what a pain they are.  What is the point of test shots if the rules are then changed, or is it a way of getting more business out of extra test runs!

They've tightened the rules up for FUD a fair bit.

0.6mm Is bigger than it seems when you're in N Gauge.
It's gonna get really tricky for detailing.

You can go much finer than 0.6mm for detail providing it is supported - eg panelling on a coach side or brickwork detail. Below that you really need to look at etched or lost wax parts. In certain cases you can get below that with white metal and wire or white metal and etch, where you actually cast the white metal detail around the etched or wire handle.

There are also lots of things that you can just about do in FUD that are best done other ways like wagon ladders, trussing, steps and platform rails as 0.6mm is a printability limit - doesn't mean its anything like strong enough.
