Walt's a professional. I'm a hobbyist. I just load the tube with epoxy with a Q-tip, then coat the rods going inside it with epoxy and cover both ends with painters tape. I do use the little piece of tape around the rods but I place it in the center, not on the ends. It keeps the rods centered inside the tube if they are just a bit undersized.
The first one I did I used an aluminum round tube with a brass square tube inside it. I wanted something else inside the square tube and realized that a round toothpick fit perfectly snug inside it. A little black epoxy around the toothpick filled the corners of the square tube. I used the pins on a camp knife for my SIL with mahogany scales. I also once used a .223 case with the neck and base cut off for a lanyard tube.
Watching and I see a vacuum pump and I cringed; I’ve been through two stabilizing. My wife said I’m done buying them. I’ve been told that a brake bleeder from Harbor Freight will do the same job; I have yet to try it.
On a budget ..Brake bleeding vacuum pumps will work 15- 20 bucks.
Can't wait to give this a shot
A break bleeder pump can work too.
Awesome stuff!

I must say...the ball bearings are a novel idea. Always innovative you are.
Thank you
Was you Kydex vacuum DIY? If so, have you made a video on that? Thank you for the educational information!
I have a Milwaukee pump battery powered that’s a sweet tool
If you do use a syringe try using a smaller volume one 1ml or 2ml syringe this way you can get more pressure compared to a 10ml 20ml syringe
You also don't need to just fill the tubes with metal! Small dowel rod of your choice of wood species!

You could thin the epoxy with acetone, but, then it would just drain back out of the tube after you took the vacuum away.
Looks like 1/4NPT.
No way would that work for HVAC in Ac pump downs we use two stage vacuum pumps and they’re like at least 50 pounds in weight
