I did have a problem trying to drill/tap the bearing hubs, I ended up having to make some really long drill bits. I'll post pictures of...

Any consternation when you first spun up the lathe? ;) It actually looks like it would be reasonably well balanced. Did the lathe...

Hi Craig, I was quite anxious when I was about to start, then I checked it again and again 😉 It was actually really smooth when...

The upper bearing hubs were machined together initially, this made it a lot easier to hold and align for machining. They were then...

The Standard was fixed to my shiny new Faceplate by clamping onto the lower bearing hub each side. My guesstimation with getting a flat...

With the Standard fixed to the aluminium plate, and appearing reasonably flat and level, it was machined in my milling machine. The...

The Standard was tackled next. The top and bottom of the Standard were uneven, so I took some time to file the top until it was nice...

Just wanted to shear this shot of doing some lapping on the lathe. This is a crosshead frame from a PM Research steam engine #6 set of...

Thanks Craig, you are correct about the thread, it was very shallow. The book that I have been using is: Screwcutting (Crowood...

My next project is the P.M. Research #5 Steam Engine. The picture below is the #5 from the P.M. Research website. It has a mixture of...

Nearly done 😊 I'm having a little break from this project for a while to let my buddy build partner catch up.

According to the plan for the Twin Oscillator you take a chunk of mild steel and turn it down to a 1/8" disk with a 5/32" shaft coming...

Thank you for your response Jason 😊 I took the first option. I took some measurements of the cylinders and covers, made a CAD drawing...

I've made the top and bottom cylinder ends, being careful to make sure the drawing sizes appers sensible. However when I try to attach...

We have machined the cylinders for our single and twin oscillators. Still have the steam passages and the mounting holes to do for the...
