[sdiy] OT- repair clear plastic knob

[tpaddock at seanet.com]

I just got a signal generator and I was 
taking the knobs off to clean under them. 
Everything was fine till I had the thought: 
"I gotta be careful, this knob might break if I drop 
it on the hard floor. That would be a bummer."

So... 
It's the clear plastic dial-skirt-bezel-thing that's 
cracked. No missing pieces, just a crack, just a big 
nasty ugly crack. Here's one just like it on ebay. 
You can see what the knobs look like.

I'd like to fill the crack with something so light 
doesn't reflect off it and it won't be so visible. 
Doesn't have to be strong. 
I can use a vacuum chamber if that helps.

The good news is that it works. Freq range is 
1mHz-1.999999999MHz, so I thought it would make a 
good LFO, tuning standard, and ring mod carrier.

Thanks,
