1. Pot Heater

Mark Turpin has re-engineered the now difficult-to-maintain Linotype Microtherm pot heater controls using modern, digital components. He's licensed the description of this under the CreativeCommons Attribution-ShareAlike 4.0 International license. Here are local copies of his writeup and its accompanying schematic:

2. Star Wheels (Linotype / Star Parts Co. Compatible)

Mark Turpin reverse-engineered a Linotype star wheel and used "3-D printing" (stereolithography) techniques to make it. He then took this design and reworked it to match the surviving drawings of several of the Star Parts Linotype-compatible star wheels. Photos of his star wheels are online on his Google+ account at:

He has released the CAD files for these Star Parts and Linotype compatible components in two formats: IGES ("Initial Graphics Exchange Specification") format (a vendor-neutral CAD data format) and STL (STereoLithography) format (commonly used as input into "rapid prototyping" and "3-D printing"/Stereolithography systems). They are Copyright 2013 by Mark Turpin and are licensed under the Creative Commons Attribution-ShareAlike 3.0 United States License. You will need an appropriate IGES and/or STL capable viewing program to view them (example: Meshlab under Linux for the STL files).

Because of their tight links with the Star Parts versions, I've filed these within the Linotype Parts Company / Star Parts Engineering Drawings & Data set of Notebooks, in the Part Numbers D* section Here are links to each of the Star Parts drawings for which Mark has made CAD models:
