The Home Machinist!

Hello, after years, I would like to update the official introduction post for "ValveGear Constructor". Since I published the program more than 15 years ago, I offered access for free and later on noted the possibility of voluntary donation which always was without any consequence for the u...

This will not work. You also must exchange the vertical order of both upper parts connected to the combination lever. This will change the vertical position of the Baker linkage and the parts around that.

The boiler needs a circulation pump, but there is no risk of explosion. As far as I know, the max pressure within the boiler when a tube cracks is such low that in Europe, the boiler even would not be located within the official pressure vessel categories.

I found some other direct supplier who is no competitor to Kacio: https://toyanengine.com/products/ Perhaps you can ask him via email if he knows Kacio or if he has some helpful contact for you. By the way: Strange pricing - US$ 10? https://m.de.aliexpress.com/item/1005003754644590.html?gps-id=platf...

The suppliers on Amazon are just sellers they are not the actual factory. I’m looking for the factory. Yes there is a hobby market that is why I’m looking to supply them. The other brands we can’t keep on the shelf. I sell easily 1000 a month Do you have an online shop? Can you give us a link? What...

First about communication: Continue communicating clearly, but do not think loudly ;-) meaning that you should not need to tell about every little delay and therefor tell delivery dates with at least 50% time reserve. This also can keep people away who do not accept delays and react with damaging yo...

Nevertheless I like to be clear. Perhaps he sometimes reads "from outside".

The above offer will end on May 14, 2022.

I could offer a test if you can wait some time for the result: Send me the valve piston positions in piston dead center position and the valve and piston position when steam inlet closing, each for forward and bakward riding, and I try to tell you what to change on your valve gear. ok I will get pi...

In my opinion, this is the only diagram you need for designing a really good valve gear
And some years ago, four points of this diagram were enough for me to restore the full power of a small 600 mm gauge locomotive with Hackwort valve gear by dimensioning a new bar.

Slide valves are "outside admission" with the steam from the throttle is surrounding the valve in the chest and moving into the drive cylinder when the valve moves enough to open the port face to the drive cylinder end. At nearly the same time (depending on Johnson Bar adjustment) the oth...
