Great video Bruce, first lathe I used was my dad's Southbend about 65 years ago, my brother still has it.
They're really made to last forever with just basic care , thanks Frank.

Nice work Bruce. Unlike the ones from Jensen, yours actually fit! Looks like my lathe--is that a Southbend 9?
Thanks Brent
Yes Sir , South Bend 9"er

Thanks for the video Bruce, fun to see how you make them. Seeing how many you made, I can understand why you wanted a cheaper source :D
Thanks Nick , this stock should last me a few years 😊

Awesome!

Thanks Bruce.

It would be great if you would do a video on how you make the chimneys.
Here you go Charlie...
I started with 5 -4' lengths , cut them all to 4". I had to make a special mandrel for the bevel at the top part of the smokestack & the base with a threaded rod to supply the clamping force. the video will show the process decently well , there were a few learning curves along the way.

the blanks all cut to length

I only had 2 that split on me, these are all finished & the bodies are 2.1/2 times thicker than stock.

I found a suitable supplier.
Thanks for your help folks.

Who did you find Bruce?
The place is called "Antenna parts outlet " Mt. Carrol Il , 1-800-238-7258 ,they sell on Ebay but I found their Ebay store and just looked them up from that info, I bought 5-48" sticks & with shipping it was a few cents over $50.00

Bruce have you searched eBay? I buy a lot of my metals off eBay now.
I found one supplier that's close Jim , but the thickness is still to great , I'm looking for the correct thickness to start with if I can , it would make the process much better.
I thought for sure on a thread long ago that someone had a good supplier for these.

Don´t know if that´s an option with you, but in the past i´ve made mine from pieces of thin walled aluminum broom handles...as i couldn´t source fitting brasstubes to nickelplate locally 8)
I'd forgotten about this little trick Jan ( hence the need for this post) I will look around.
Thank you 😀

Is Jensen out of them?

In the past, I have always bought the chimneys already made up from Jensen.

The tube size for brass has been 3/4" OD with .022" wall thickness.
Aluminum is likely the same.

I make my own, but thank you.

I've bought some round stock in the past ,but it took a little more work that I wish to give them now & would like to find the correct size .
any good sources/supplies would be appreciated (US only)
