Unfortunately, had a major failure with my speedbrake molds. Not sure what went wrong, but the surface coat broke away on the inner surfaces and very poor raised rivet detail reproduction, plus the plugs got trapped in the main molds. No way to free them......
I will have to start again and print new plugs and re-finish. I think I will not try to mold the lightening holes, but just mark the outline for later cutting out, plus make the molds in 3 pieces, not 2 so that I have a better chance of removing the plug.
I made the molds in the same batch as I did the rudder and flaps, so not sure what went so wrong. This was my first major molding failure so far, so I guess I can't complain too much.
