Doc, will you be putting some kind of insulator between the hot cap and the finned part? That will also help a lot with limiting heat transfer to the main part of the engine. Phenolic works well for that if you have any handy.

I'v never bothered with insulation on any of my motors. This one has an internal thread that screws directly on the end of the cylinder of a BETTA type motor

   I am planning on using graphite material that I have left over from my stirling fan build. What I am building I would think it would run ok fr short demo's without anything.
    But if I attend any shows (which I'm hoping to do) it would run for extended periods so I will be adding an insulating material. I never gave phenolic  I do have some thinner stuff that turned out to thin for circuit boards that I wanted to build. I may just give that a try. 

Thanks for the comments guys it is appreciated!

PS Ian I like that idea of internal threads

Oh year - I had days where I shouldn't have gone in my own shop and I had days where my employer would have save a lot of money if I hadn't gone to work ....  :wallbang:

Looks like you generally are going in the right direction though  ;)

Thanks Bill!

I think its just my nerves getting me down. The closer I get to retirement the more acid re flux  and the worse I feel. Keep think I hope I'm doing the right thing. I have 11 more working day's left after today.

Congrats Doc...I've got 56 working days left. I am looking forward to more shop time for sure. But I agree, it is a life changing event. Some anxiety is inevitable I suppose.

Congrats to you Bill!
Yes I am looking forward to more shop time and in the summer I love gardening and yard work and If I get bored I've been offered a part time job mowing grass at a cemetery just about 1/2 mile from where I live. I've been working at the same place for 43 years so it will be a huge change for me.
  I do hope to be able to attend some of the bigger hobby motor shows.

Hey just rub it in don't you  >:( Some of us are way back in the cue for retirement :( and we would love to be as close to the front as you guys....

Just imagine every day that hard decision: shall I work on this model  or go play the garden or maybe I could look at starting that model :noidea: When others of us were forced hours before hand to get out of bed and drive to work and are now sitting looking at the forum as it is the only way we can indulge in the look and feel of swarf for most of the day :stickpoke:

Don’t feel bad it 21 years since I retired  :old: :Love:

Yes it was early retirement I was 50 when I gave up w**k  :cartwheel:

I have not regretted it one bit


IMHO it’s the best thing to do  :stir: Jo

My aim is for a accurate part with a good finish
