What you have is a "Model Taper Pipe Thread" and to tap a bushing for

Hi,
metric guys like myself cannot help grinning slighly about the problems
getting the right rod size for cutting standard screws. In metric,e.g. a
M2 is cut on a 2mm rod, readily available in the "metric" world. But not
all is lost: Micro-Mark sells an assortment of brass rods for screw sizes

That would make me nervous, I break M2.0 taps just by looking at them wrong.

fact it was originally intended to improve the appearance of fittings, and
standard USNC or NF (or UK equivalent) are used where appropriate. It's
also possible that in Ga1 not all threads would be best made in ME.

I'd prefer to have American standard bit used. things I can easily get
a hold of here in north Texas. I have built two 'Lady Anne' chassis kits
and can't find spare screws for them here in the US. I'm sure any of the
dealers can get them for me but so far it's not been a necessity as I can

know if a US prototype loco would have any appeal. So I am leaning toward
using American standard threads...But I could be persuaded to change.
So here are some more questions...

Also, if you are playing about with or changing between different weights
of oil, a lubricator with adjustable feed rate is desirable as the this can
vary considerably.

In traditional model engineering practice there has been an attitude
