I am in a kind of a fix right now, and need to find a replacement for the VFO Tube dial in my HG-10 VFO. The tube is badly
cracked and I have been looking on ebay for some time and nothing has come up. I did get one in the past from Ken, KE4MG
but he no longer makes them and does not have supplies to make another one.
    Does anyone have a source for these dial tubes, or know how to make them. With fingers crossed, This is

The ONLY source is a parts VFO.  To minimize your cost try to find one with a nice dial tube, but rough otherwise.

if you were to very carefully take the dial glass tube off, and roll it with the light on a copy machine plate, and copy that master to a clear acetate or Mylar sheet, and wrap that around a plastic tube of the right diameter, you'd be close enough for amateur work.  don't attempt in any way to remove the metal plugs or axle, just roll and pray.  or a scanner plate, where you can see the reader move and roll with it, newer copy machines zip by too fast.  McMaster-Carr online should have the plastic.

glass is a colloid and considered a "statistical material" in architecture, I am told, and the consideration of skyscraper glass is not "can it break," but "can we manage breakage so nobody dies."

K9STH has the dial drum scale.

IF you need the tube itself, you could ask Glen.
Clear plastic mail tubes, plastic, acrylic, or polyethylene could be considered.

www.radiodaze.com

Has added the capacity to make replacement dials recently.  You might call them and discuss your needs.  They are a reliable vendor located in upstate NY.
