Re: [Z_Scale] Re: Pennzee heavy weight truck question
- Yes bearing cups will work but I know of no source over hear and up to
now did not know of a source other 2mm society which requires
membership to purchase. Do not know a commercial etcher who will do
small jobs over here either. As for the drawing I like the Japanese
way of doing the layout of the overlays as one sheet with fold lines
so they fold and they do up to three layers in this manner. I think
for the builder there are much better opportunities for craftsman type
support in the hobby in the UK than over here.

volume. They are actually shallower than the 2mmSA ones which makes them
even better for Z scale work. Markits will happily sell you them in

bigger etched kit people will stick other jobs on corners of sheets
though - dunno if it is the same in the USA or not.
