Resurrection Time Again.......
« on: May 09, 2012, 04:24:36 PM »
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.  :thumbup:

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

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

http://i110.photobucket.com/albums/n95/Dayjo/After%202012/P1020395.jpgResurrection Time Again.......




Time to start on Robbo......
You've all seen the story, up to pres..........   http://madmodder.net/index.php?topic=6110.0

First off. I don't like relatively thick wall, brass hot caps........

http://i110.photobucket.com/albums/n95/Dayjo/After%202012/P1020382.jpgResurrection Time Again.......


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

http://i110.photobucket.com/albums/n95/Dayjo/After%202012/P1020388.jpgResurrection Time Again.......


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........

http://i110.photobucket.com/albums/n95/Dayjo/After%202012/P1020400.jpgResurrection Time Again.......


Looks good now........

http://i110.photobucket.com/albums/n95/Dayjo/After%202012/P1020403.jpgResurrection Time Again.......


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

http://i110.photobucket.com/albums/n95/Dayjo/After%202012/P1020405.jpgResurrection Time Again.......


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

http://i110.photobucket.com/albums/n95/Dayjo/After%202012/P1020406.jpgResurrection Time Again.......


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

http://i110.photobucket.com/albums/n95/Dayjo/After%202012/P1020407.jpgResurrection Time Again.......


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

http://i110.photobucket.com/albums/n95/Dayjo/After%202012/P1020410.jpgResurrection Time Again.......


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

http://i110.photobucket.com/albums/n95/Dayjo/After%202012/P1020411.jpgResurrection Time Again.......


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

http://i110.photobucket.com/albums/n95/Dayjo/After%202012/P1020412.jpgResurrection Time Again.......


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!  :D

Good to see you back to it too, David.  That hot cap looks better than new!
I think you had a good day, all told.  : )

Thanks Dean!
The bundle of bits was sent to me from Australia, as you know. To be auctioned for the Junction 26, Children's Hospice Appeal.

Like me, you also realised it was beyond any sensible hope of running........  :palm:

I fretted, all winter..... What  would the owner think?  :scratch:  :(

I sent him this pic, and an explanation. I'll give£10 to the charity, and call it Stilldrillin's Failure.......

http://i110.photobucket.com/albums/n95/Dayjo/After%202012/P1020380.jpgResurrection Time Again.......


Bless him! He fully understood. Told me to bin it, and promised to match my tenner!   :D

My Scottish pal rang, that evening. He has a fetish for these 'orrible things......
I'm posting it up north, and he's also giving a tenner!  :D

Thirty pounds, for the Children!  :bugeye:     

The oscillator is to be auctioned too.


What a lovely, caring collection of friends we are..........   :clap: :clap: :clap:

Having now had the time to examine what I'd achieved with the hot cap. I was feeling very pleased with meself.  :D

I had only ever silver soldered two small joints before.
It just goes to show, if enough notice is taken of techniques shown on here, the beginner can produce some very satisfactory work.  :thumbup:

Displacer time!
The cap bore is 1.4". I cut some steel sheet .020" thick, and wrapped it around a 1.25" ali bar.
Ground the inner overlap to a feather edge, and strapped it tight.

http://i110.photobucket.com/albums/n95/Dayjo/After%202012/P1020413.jpgResurrection Time Again.......


Then turned the outer feather edge. Moving the pie clip section by section.......

http://i110.photobucket.com/albums/n95/Dayjo/After%202012/P1020416.jpgResurrection Time Again.......


Swapped the clip for some stout wire, and fluxed........

http://i110.photobucket.com/albums/n95/Dayjo/After%202012/P1020418.jpgResurrection Time Again.......


Then silver soldered........

http://i110.photobucket.com/albums/n95/Dayjo/After%202012/P1020419.jpgResurrection Time Again.......


Just a nice line showing in the bore........

http://i110.photobucket.com/albums/n95/Dayjo/After%202012/P1020422.jpgResurrection Time Again.......


Cleaned up nicely.........

http://i110.photobucket.com/albums/n95/Dayjo/After%202012/P1020424.jpgResurrection Time Again.......


I think that will do nicely........

http://i110.photobucket.com/albums/n95/Dayjo/After%202012/P1020426.jpgResurrection Time Again.......


A busy few days ahead, including Harrogate. End caps next. As, and when.......

Thanks for watching!  :)
