Re: [TCML] Old VDG and Tesla coil found in attic

[Ed Phillips <evp@xxxxxxxxxxx>]

   Answer to part of your questions.  The VDG obviously needs cleaning 
up [what is the column material?] and the top filled out to a full 
sphere.  As for the belt, there is stuff called "Theraband" which is 
used in physical therapy.  Thin rubber [or possibly neoprene] sheet 
which can be had in rolls of up to 25 feet at least and widths up to six 
inches.  It can be had in a number or different color colded thickness.  
I've used it and found that I could get by with using ordinary rubber 
cement [great big surprise] to join the overlapped ends of the belt as 
long as there wasn't too much tension.  Application of the cement makes 
the stuff curl so I stick it down with double backed tape with plastic 
or cardboard backing and leave the tape in place until the cement is dry 
and the two pieces joined.  I actually made a keyed fixture to make the 
fit accurate.  Problem is always getting the belt tension just tight 
enough so that it won't lift off the rollers but not tight enough to 
bind the bearings.
