Holy smokes. I don't see how this meticulous of an operation could ever be
worth the time and trouble. It sounds like this activity would take ten
minutes!

Whatever happened to wetting the rubber with saliva and tying and overhand
knot? I then tie a 'safety' knot with the tag ends forming a 'T'. Pull
everything very tight, trim, and you're done. I've been doing it this way
for 20 years and I can't recall ever having a knot slip on me. The whole
process takes about 15 seconds.

For making motors to precise weight I cut the exact length required, wash
the rubber, dip the ends 3" into 30% strength glycerine/green soap lube and
tie
an overhand knot as close as possible to each end and very tight. I make a

loose clove hitch in some tan thread, "mercerized cotton covered
polyester",
selected after extensive research and testing consisting of reaching into
the
drawer of thread and pulling out the closest color match to tan rubber. I
put the ends into the loose clove hitch from opposite directions so the
knot
is past the loop, snug down the thread knot, lube everything, pull the
strip
through until the rubber knots jam up against the clove hitch, tighten the
clove hitch and follow with a square knot and a half. Cut the thread ends
off
about 1/8" or less. Then I pull the rubber strip very tight just to check.
I
have been using this method with motors of about 0.042" x 0.070". I break
a
lot of motors, but only one came undone at the knot and it may have been
the
overhand knot came out and slipped through the thread.
