Two novice bashing questions

[E-L man tom]

I think you have tie decimal placed too far to the left on those thicknesses; they should be 0.010 or 0.020. that's one hundredth to two hundredths of an inch, not thousants (one thousanth = 0.001). On that note, even 0.040 thickness would work well and it would give better strength to the integrity of the cab.

 1. What thickness styrene should I use to build a metal cab?

Whatever thickness you can work with best.  .0010 to .0020 would be a good start.

 2. How do people paint the very fine pin striping and designs often seen on 1870 +/- tenders?

Decals.

I'd like to try my hand at bashing a 4-4-0 On30 loco.

 1. What thickness styrene should I use to build a metal cab?

 2. How do people paint the very fine pin striping and designs often seen on 1870 +/- tenders? That seems way beyond my ability.

 Thanks.
