I have been able to get a little more done this week.
First I made my PVC tube and soaked the Way and Base Tubes in the Rust911 to remove the rust.
For the inside tube, I 3D printed some end caps that where flush to the sides of the pipe so they would slide into the inside of the tubes. The plugs where printed using PETG which is the same material water bottles are made of. You can use regular PVC cement to glue them to the PVC.

This is a shot of the PVC tube with one of the Base tubes in it soaking overnight.

While the tubes where being de-rusted, I 3D printed some brackets that I used with some 608Z bearings (skate board bearings) to use to clean and polish the tubes after de-rusting.

I then used my Eastwood SCT to remove the remaining rust on the Way Tubes, and the paint on the Base Tubes. I followed up that with using a drill on the jig to turn the tubes and finish them with 320 and 400 grit sand paper.

This is what they looked like when finished.

Finally, to prevent them rusting from the inside, I used some Eastwood Internal Frame Coating on them.
