The shoulder hydraulics are nearly done. It took me a bit longer than expected but I'm happy with the result. All that is left is to sand out the milling marks and drill and tap the mounting holes.

More progress. I'm really happy with how these are turning out.

I'm making progress but I'm down to 2. I've made some stupid mistakes but it happens. I'll get there in the end.

Be careful you might be the greeblies guy before long. These look very cool.


That is not a bad idea but I’m only making a set for my own use, at least for right now. I may make some more in the future to offset the price of the parts I can’t make but I don’t think I could ever compete with CNC ...

Those are amazing


Thanks!

I've started tooling up for the shoulder cylinders. I don't have a straight knurling tool so I'm making the knurls using my lathe like a shaper. A tool bit was ground to 90 degrees which is fed longitudinally using the lathe carriage advancing the tool bit until final ...

A couple of close-ups.


Next up will be the shoulder hydraulics. They are also pretty simple but there are a couple of the details that may be a little challenging to reproduce.

I’m planning on machining all of the greeblies for my R2. 3D printed details are okay but machined aluminum parts are so much nicer. All of the machining will be done manually so some of the details will be challenging but should be fun. First up is the shoulder buttons since they are the simplest ...
