I finished the second blank mold last week, I have one mold that is right
handed and one that makes a left handed spiral core in the blanks. I took
blanks to Union IL to introduce them. While the end product is a standard 4 1/4
( mine run 4 1/2" at times) The blanks come out of the mold thicker than an
Ediphone blank, and the molds in fact will make dictation blanks that are 6"
long and will even work with the Ejectomatic on the late Ediphones. Today was
my first time molding with two molds, and we started molding at five, and ended
at 7pm CST, and molded 6 good blanks during this time, there was one that was
rejected, otherwise there would have been seven. The blanks are shaved to
2.190" in diameter, and I have a stop on the shaving knife, that when they
get to that size, it stops shaving,. I am wondering if this even is too
thick? I measured lots of original cylinder records and found they range from
2.130-2.175" in diameter. I want to offer the most shaves per
blank. They are still the same price. New boxes will be here soon, so they
will soon sold singly instead of dozens and half dozen boxes. At present
though they are sold the half and full dozen until the single boxes are done.
The new ordering process is that you put a suggestion, on a list, that you
would like blanks, and when they are finished, you pay, and they are shipped, I
think this is as fair a method. The new molds certainly have reduced the
defective blank ratio to very few, and the blanks are much faster to mold. I
also have a 20 year old apprentice who is learning how they are made. The
first job was shaving blanks, and now watching how to mold records. My goal
will be to mold 40 blanks in an 8 hour period.
Sincerely
Shawn Borri
