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:

Re: Machining Cylinders - How to Do?

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.

Re: Spoked wheels in CAD

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...

Re: Does Anyone Recognize This Name?

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...

Re: Necessity of hardened crank pins on 3/4” scale

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....

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.

Re: Making ZA27

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...
