I was having a look at Ron Chernich's web site it seems John Strachan of Hobby Mechanics in Brisbane is about to produce castings and drawings for a gear cutting machine that was published in the Model Engineer in 1949, able to produce spur, bevel, and helical gears of modest size. Unfortunately for John he had already produced patterns and castings before Ron Chernich had finished the 3D Cad model and found that a number of bolts could just not be made to fit. John is known world wide for his quality castings so I have no doubt that they will be right by the time that they go on sale. Sounds like it will be a great project they are calling it the GC100. Plans will have dual metric/Imperial dimensions. http://www.hobbymechanics.com.au/ http://modelenginenews.org/ Lee MODEL ENGINEERING DISCUSSION LIST.
