[Heath] Knob Inlays and Skirts

[G3OOU at aol.com]

Hi Ken
 
I have re-polished Heathkit knobs on my microlathe using a quarter inch  
piece of rod in the chuck on which to mount the knob, some Brasso, a 
toothbrush  and cloth. The problem is that it will tarnish again in time and the 
brasso  needs cleaning off.
 
Ideally what is required is access to an anodising supplier since silver  
anodising will last for a long time but it may require the aluminium parts  
to be removed from each knob which is a more difficult task. Alocrom is much  
easier but a less attractive finish.
 
The skirts can be removed by machining out the inside centre brass a little 
 but they would need to be stuck back in after processing with an epoxy 
adhesive.  I have done this in order to convert standard SB-Line knobs into 
dual concentric  ones.
 
The front centre pieces are almost impossible to remove without damaging  
them but a new thin piece could be stuck on top of the existing piece. Not 
sure  if applying some heat would soften the existing adhesive without melting 
the  body?
 
No idea what the cost would be to make new metal parts or even new  
complete knobs - anyone any ideas on quantity - v - cost? There  must be a 
significant demand.

So  do I. If you find a solution, let me know, please.
