Brass Parts
We make custom parts; one of a kind or
dozens according to your specifications.
We specialize in Brass Machining, but
various plastics, aluminums and soft
steels are also available. Shown here
is one of Derrell's projects (C&S 59 in Sn3)
with a number of custom parts that include
domes, diamond stack,
headlamp reflectors and a shotgun stack.
For that one of a kind unavailable part for
HO, S, G or larger models

S scale sand & steam domes
for a C&S B-4-C class narrow gauge engine.
Each dome consists of 6 parts - base, lower ring, trunk, tip, upper
ring and
cap (either lid for sand or one of two styles of steam turrets). |
|
|
|
 |
One of the more challenging
tasks in creating a dome in brass is to accurately
cut the "saddle" radius. This view shows a special clamp
Derrell devised to
hold the dome base (after it was soldered to the trunk) while
cutting the
radius with an end mill. |

At the turn of the century
railroads all over the country were replacing their
diamond stacks with short smoke boxes with shotgun stacks and long
smoke
boxes. The C&S turned to this combination because the coal
from Baldwin
Colorado burned better with this arrangement.
This lot of stacks was cut for a client. |

How to turn a stack with no
less than 3 angles in its length?
First cut the rod to the widest diameter. |
|
|
|
 |
Then using a graver carefully
turn the radius near the base. |
|
|
|
 |
After cutting all the angles
and tapers finish the stack by cutting the lip at the
mouth of the stack with another graver. |

A fine sanding stick strip as
well as 00 steel wool brings the piece to a high
polish. |

These parts were
cut to exact scale sizes to within .003" (that's about
1/4" in S scale). They are not meant to be
patterns for casting.
Please see our
Custom
Design Page for pattern masters for lost wax and
rapid prototyping processes. We do custom etching
patterns as well.
Our standard
fee for making custom parts and patterns is $35.00 p/h.
