Today I glued parts together and primed.
I have a lot of little areas to fill and smooth.
The 3D-printed parts are not the best fitting,
and have irregular surfaces.
The final finish will be flat black,
with a little weathering.

I know well about surface issues of 3D-printed parts,
however the picture of the current status looks good.

I would have liked to add handrails to the boiler.
I have some HO stanchions and wire.
But drilling the hard metal boiler for them,
was beyond my abilities right now.
The surfaces of the parts are very rough,
it really shows with the primer.
I am hoping the final paint and weathering,
will hide most of it.

I usually put a thin coat of Bondo glazing
& spot putty stage 2 before priming,
then sand smooth.
Works great on metal and plastic.

It is 1 part (no mixing),
can be used over paint,
dries fast and sands easily.
I love it.
Jose.

The engine is about finished,
and I am very disappointed with the results.
Ill fitting, and rough texture of 3D-printed parts,
detract from the nice proportions of the model.
I've had the parts for a few years,
maybe the technology has improved since then.
I am considering scrapping the boiler and cab,
and starting over.
The tender and chassis is one unit,
so I could fit a new superstructure easily,
if I can find something suitable.

I have these possible replacements,
from some train show finds years ago.
I need to think about this.
Thanks for following along.

Here is a mock-up of a new shell for the Roundhouse 2-8-0
using one boiler with the handrails, and another 3D-printed cab.
The tender is from Bachmann,
and I've started to widen it, to match the width of HOn30.
I would not need it with the 2-8-0, as it has a tender drive.
The cab will need work to smooth it,
I think I'll try Jose's tip and use the spot-putty.
I wish parts were available in styrene plastic.
