[Heathkit] Need IO-104 Oscilloscope Vertical Attenuator Switch

[Donald Spoon]

Just to close the book on this saga... I did use the straight super glue 
(cyanoacrlate) which worked well.  One of the breaks went through one of 
the holes on the "dog ears" used to mount it and represented an area of 
potential weakness.  I noticed a series of small holes around the 
perimeter of the wafer, a little larger than a single telephone wire 
with insulation.  This break was in an area where there were no 
electrical connections so I "reinforced" the breaki with a loop of the 
telephone wire that was twisted to provide a mild bit of tension.  I 
suspect you could do the same with a bit of twine using a surgeon's knot 
to maintain the tension while finishing the knot.

I read up on using super glue and baking soda on the internet.  
Apparently you can use this compound to make castings!   I am going to 
experiment with this technique to see if I can make replacement plastic 
gears, etc.  I also suspect you could use this material to add to the 
"reinforcements" above.

Thanks for all the help!
