The upper boiler in this shot is for NPC No 1.
The lower boiler is for a Glover coal engine. |
 |
Aluminum L Channel was laid on the boiler. Its edge was used to
draw an alignment line marking the top of the boiler. |
 |
Once the line was drawn, a sheet of paper was wrapped around the
boiler. Lines drawn on the paper mark the beginning and end of the
boiler circumference. |
 |
The diameter was measured. A third line was drawn at the
midpoint of the two overlap marks.
The paper was then wrapped around the boiler with the midpoint on the
top alignment line. The point at which the overlaps align at the
bottom of the boiler was used to mark the bottom alignment line. |

A template for boiler dimensions and cut can be found in the MasterClass
Articles section of MyLargeScale.com.
The bottom alignment line was used to mark the borders of the slot
that needed to be cut to clear the Aristocraft C-16 motor block.
The slot has been cut in the top boiler in this photo.
The slot is 1.87" long and 1.24" wide. |

The top engine in the left photo shows the boiler placed on the C-16
frame.
The Glover coal engine chassis is the lower of the two in this photo. |
