[Heath] HW100 stringing of load control pulleys

[Gordon Gwillim]

Hi Dick. I can do it but have no hope of describing how by this keyboard.  Grew 
up restringing radio dials as they wore out often in those days. All of the dial 
twisters weren't hams. 
There is something to be said for "rubber bands" and I guess that was the 
thinking behind the original Heathkit design.
I make my own drive belts from larger O rings and glue. If you make the ring 
just about 1/4 inch shorter than what it measures around the two pulleys and 
then be careful to make exact 90 degree cuts to the O ring with a sharp box 
cutter knife, then the stuff we call "crazy glue" will make the ring into a belt 
again. I usually manage to wreck a few before I get a good one but they work 
fine when it is done correctly.  I use the same procedure here on the farm to 
make O rings of sizes I don't have on hand, or to shorten ones that have become 
stretched. Once marked, the two ends of the cut  O ring can be laid side by side 
and a single cut with the razor knife will make matching surfaces.  The glue 
sticks instantly so you have to get the ends together correctly the first time 
or you have to start over.  I have the glue that comes in larger amounts and is 
slower drying and has to be stored in the refrigerator. It is a bit more 
forgiving and will allow some alignment after the first contact. Good luck with 
the Heathkit.
Gordon.

Well, I got so frustrated that I gave it up for a while. Back at it 
again. I have tried 2 of the simpleist methods that were sent to me (4 
of them) and in each case I could not get more than a 90 deg turn.

Obviously the problem is in the positioning of the pulleys before I 
start to string it, as well as the position of the tune knob. Like I 
said before, I is a lowly technician not a dad-burned engineer.  I can 
usually work out such problems eventually but I am out of patience 
now. Bout ready to put the rubber band back on.

HEEEEELP!
