Trevor, that looks freaking amazing, I hope you are very proud of yourself. :thumbup:

As far as name plates go, it looks like your plates are lifting at each end the same as mine do. I am going to thicken up the base to try and avoid this but I am not sure if it's getting them off the build plate that causes it or whether it's the curing process under a UV lamp, I might try an outside natural dry to see if it's that. Let me know if you manage to overcome this.

EDIT: Another question, how high and how wide are your rivets as they look perfect, mine never come out as they look in CAD, lol.

Nice lining!

Incidentally, (unless you get it right first time, of course!) what do you use to remove any mistakes while lining a plastic model? I use lighter fluid on metal locos, but want to line a tender I've made from plastic at some point and wonder how it would hold up?

Thanks,

Andrew.

Thanks for the complement!

I am quite pleased with it.

The rivets are 1mm diameter and 1mm high. Just rods - not actually rivet shaped. I don't think its obvious when they are printed - and even less so when painted.

The name plates were flat when I took them off the build plate - but warped under UV. I was planning to just glue them into place and expect the glue to hold them flat.

I do the same. I have been using lighter fuel on the plastic models as well. The underlying paint is Valejo acrylic airbrush paint and doesn't seem to be affected by the lighter fuel - which evaporates almost instantly.

Oh and I do make plenty of mistakes!

I think I'd try to print them on supports with a plate on the build plate, and then trim the supports after curing. Doing it like that should hold it flat.

Yes I printed them with supports and a raft - but took them off the supports before exposing to UV. Will be interested to see it curing with supports in place has any effect

I think natural drying on sunlight (when we get it) might improve this vastly as I have had other things go a little funny under UV that didn't in the sun. UV lights also make the resin change colour, again, the sun generally doesn't have such an effect on the resin.

You should be very proud of that. Well done indeed.
