The Home Machinist!

If you did not see yet, my program gives excellent results based on main basic dimensions within 3 to 15 minutes, immediately after typing the values into the "Quickstart form". But the reason I write is that I am still open for supporting someone using my new version of valve gear which i...

In my opinion, having learned how to read diagrams, using an elliptic valve event diagram helps understanding valve gears much more efficiently and sustainably. You do not need to keep lots of dependencies in mind but instead can catch them all at a glance looking at the diagram.

He had asked for further help after not responding here. I think I will answer his next question with a link to this topic here. Seems to be a rather impolite person...

Someone has to go ahead, else nothing that has not been built yet will ever be built. And Mackwell seemingly is such one. Follow his online-news and see what will happen. It seems to me that he he meets more requirements for a successfull visionary entrepreneurship than most other people. Even altho...

The movement and coordinates for opening and closing are the first ones to be fixed when building a fully new steam loco, but you need a basic understanding of the idealized movement for that. Starting from an existing design, you can get along without this basic understanding itself but have to fol...

Not really.
This one is carbon neutral (in today's sense) and original size.

How about this one?

"From $64,950* + GST" (NZ$)

Does anybody have any experience with these products for live steam?

Now I updated the official VGC website with my new "Iterator", a (mathematically) simple micro-solver for 1 or 2 equations with 1 or 2 variables, but very useful for closing the gap between "only new design" and "only remodeling of an existing valve gear". For broad use...

Dear members, for those who do not read the garden railroad postings in the other forum section, here my introduction of my valve gear design online program. Currently, I decided to concentrate on park railroad locos (about 15" gauge) and above, so here is my posting for you. Please use the dir...
