Building ìMillie,î a small oscillating steam engine/Pam Weiss
This simple bar stock
steam engine is a good beginnerís project. The flywheel is just æ" in
diameter. Plans for building ìMillieî are included in
Building a steam engine from bar stock is a better first machining project that a casting kit, because if you make a mistake, you can saw off another piece of metal stock and start over. If you mess up a casting, the project is doomed unless you can buy another casting. These plans were originally shown in Modeltec magazine, which is no longer published. Ed Warren designed the engine and gave us permission to re-publish them in Tabletop Machining. If you donít have the book and would like the plans, contact Sherlineóor better yet, buy the book!
Sherlineís lead toolmaker Pam Weiss built the engine and photographed a number of the setups along the way. You can find plans and more detailed photos on pages 330-332 of Joeís book.

An advantage of the Sherline lathe is that the headstock can be rotated to cut tapers. The disadvantage of this adjustable design is that perfect alignment with the tailstock is more difficult to achieve. The solution to this for those who need perfect headstock-to-tailstock alignment is to make the adjustment at the tailstock end using these special purpose tool holders. They all have a rear plate with a #0 Morse taper for the tailstock spindle. The front plate can be adjusted in relation to the rear plate to achieve perfect centering. A witness mark on top of the rear plate makes it easy to return the holder to the aligned position when used in the future so it doesnít have to be re-aligned each time. P/N 1201 replaces the standard live center with an adjustable one. P/N 1202 allows the attachment of a 1/4" or 3/8" Jacobs drill chuck. P/N 1203 accepts tools you make yourself that are held in place with a custom turned split collar and set screw. P/N 1204 has a #0 Jacobs taper to press on the small 5/32" drill chuck, and P/N 1206 holds 1"diameter tapping dies. A 13/16" bushing is included for smaller dies. For centering, drilling or tapping small parts where perfect centering is critical, these adjustable tool holders give you new options.
