Re: front panel knobs of 2465 2446 2336 falling off
Thanks for the suggestions. Since parts of what hold the knobs are now gone, I'm going to try hot glue. If it is wobbly afterwards, I can reheat and try centering again until good. Good to know

Re: front panel knobs of 2465 2446 2336 falling off

Re: front panel knobs of 2465 2446 2336 falling off
Personally I recommend ultra low melt temp hot glue. It works well to stick it on, but if you need to remove it you can use a heat gun on low setting to warm up the knob and soften the adhesive to

I had one cracked knob on a 2465, so I pulled another to be able to use that pot, and the pulled one lost most of its spring clip that keeps it on the shaft of the pot. What methods are known to work

Re: Disintegrating Handle on my TM503
Also look into "gun bluing" for rustproofing. I have seen many equipment handle core/spring things with that characteristic deep blue color. Ed

Re: Disintegrating Handle on my TM503
AFAIK, no, though Naval Jelly is another alternative, although messier. The key with Ospho is that it converts iron oxide to iron phosphate and thus prevents further rusting. One can find it in

Also, for the rusty metal strap, there is a product named "Ospho" (a phosphoric acid solution) that changes iron oxide into iron phosphate and stops the iron oxidation process. One removes the loose

Is the original leather covering on the metal strap still all there? If so, consider using some blue shrink tubing. Put on one layer, shrink it, slip a second layer over it and shrink it too. If the
