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 one took no time at all......... It's scrap!

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!
