The North American Live Steamer, Volume 1 Number 4
Here are three of the pictures that I promised to have made for you.
Photo 1 is a fair view of the fabricated drive wheels 6-1/4 inch on the tread. They look quite a bit like cast ones.
Photos 1 and 2 give a good view of the fabricated cylinder block. The data on this is:
- 1-1/2 inch bore
- 2-1/2 inch stroke
- Piston valves (no rings as yet) 7/8 inch dia by 3/4 inch travel, long lap,
- 75% cutoff
The cross head in Photo 1 is a Little Engines casting, modified to the laird type---back cylinder head is also Little Engines material treated likewise. No alteration on the valve guide head. The side and main rods are 1040 HRS torch cut to shape and hand ground to produce the profile. Motion work all cut from solid material and electric welded where necessary. All of the truck wheels were torch cut from 3/4 inch 1040 HRS plate.
Photo 3 not so good. It's supposed to show the fabricated trucks, but it's a little dark under there. Nevertheless, they are fully sprung with swing motion centering, as is the front engine truck, which uses heart link centering. Tender tank is 12 gauge steel, all welded construction--frame is 1x1x1/8 inch angle also welded.
