Have you fellas dialed in both ways? From the spindle to the bore then from the table to the spindle? On the subject of dividing plates I never use mine anymore. I put together the Rotary Controller from “World of Ward” and have not looked back. Check out his web site. The unit is a snap to...

Hey guys check out this video from Joe Pi. I think most of us know him from his you tube videos Go to minute 12 and watch from there.

On some or a lot of tables you will find the center of the RT centered off the spindle will be different than if you center the RT off the table. Check it out

So did I and maybe some of the more expensive ones are. But just for giggles put a magnetic dial on the Rotary table and run the indicator around your spindle or better yet inside your spindle,you might be surprised

Hey guys. All the conventional wisdom says to align a rotary table you put a dial or a coaxial indicator or a rod in the spinal and swept the center hole of the rotary table. Than rotate the spindle and 0,0 your table. OK..........After you do that put the dial on the rotary table top and sweep...

Wow good to know. I don’t use mine a lot but so far no problem I will start using it a bit more

Please stay in touch. I am using mine a bit more now

I will give it a try tks

Here are a couple of cylinders I did for Twin Cyl horizontal I built. Machining the body radius was interesting.

Yes the brass part is the valve pdf. I machined out the sectors to see if more than one power port was open at the same time. And indeed at tdc 3 are open. So when air is injected that should only drive that piston down the ports on either side are open as well. I triple checked my dimensions...

Very nice

Hey Scott thanks for the help. I searched and I could not see any build log. I can find the post for the plans but that’s it.

I am just starting to build this engine now. Is there a build log for it anywhere?

Great stuff. On one of my twin horizontals I am machined the steam chest into the cylinder itself it worked well
