As most of the workshop and home, round toits are now sorted. It's time to make a start on this year's resurrections, from the orphanage.

This big wobbler took an hour or so........

Time to start on Robbo......
You've all seen the story, up to pres..........
http://madmodder.net/index.php?topic=6110.0First off. I don't like relatively thick wall, brass hot caps........

Too much heat can pass to the cool end.
So, I sawed it off, to replace with a piece of steel vacuum cleaner pipe......

I noticed the original end cap was concave copper, and painted black, to absorb the heat.
A rub with emery highlighted the hammer marks........

I radiused a piece of delrin, and gave it a tap, or two........

Looks good now........

Carefully parted off, just behind the cap........

Bored the cool end 1/8" deep to take the chrome pipe, and cap.
Looks ok, I think.........

I emeried away the chrome, and silver soldered the cylinder in place........

Then after a clean up, replaced the original copper cap......

Another clean, and a quick assemble. I think they look made for each other......

Not a bad day's work.......

Need to sort out how to make a lightweight displacer now, cos I don't like the wasted volume of the regenerator.
It's nice to be back to it again!
