The Home Machinist!

As far as I know the turrets were made by Emco, they are neat little machines and I keep an eye out to see if one pops up for the right price in my area.

Here is some good info on their history:

Here is a neat video I just came across yesterday showing the restoration (re-boring and machining mating faces) of a stoker engine from the Nashville, Chattanooga & St. Louis Railway No. 576 steam locomotive that is currently being restored. The boring and machining shown in this video is done on a...

If the end goal is a pattern that is to be sand cast there are many factors that need to be considered when drawing/designing the wheel/pattern. The three most basic principles are: shrinkage, draft and machining allowance. If any of these three are not considered then the end casting will not be as...

They can also be done completely on the mill with a boring head.

This is a bit late, but yes, I have his/her drawings. I thimk this is a woman, as I see only women coming up on the net with this name. I suspect that her husband may have actually drawn them but she either cleaned them up and "copyrighted" them, or he died first. I am very curious about him/her. I...

Hi Jack,

Will your power reverse be functional?

It seems the aforementioned issues with the engine being too "tight" were with the design / choice of fit. If "Mr. Precision" manufactured his part exactly as the design intended, and the part failed, then the failure was of the design and not the manufacture. Maybe the choice of fit was not right....

Very cool, thanks for sharing!

...So what's the moral of this story...if you want ZA-27, buy the ingots, trying to make them may be more trouble than it's worth...

Yup!

Fusion 360 is free for hobbyists:

Also- there is no 2D vs. 3D program, it is all in one, if you do not want to use the 3D features then simply ignore them.

I have melted and poured bronze and brass alloys from their base materials (copper, zinc, tin, lead.) You always melt the material with the highest melting temperature first and work your way to the material with the lowest melting point. This process can be difficult and frustrating, especially whe...

...If we had more of the cylinder castings, this would be a locomotive that would be simple and cheap to build...

If there was real interest producing new cylinder castings would be an easy fix... wheels too.

Do you have a complete drawing set for the engine?
