Correct it will vary for each batch. This chart works for the rubber I
use which is mainly 3/02 and is close enough for my 5/99 and 10/97. It
gets me in the ballpark but I still go by length and weight of the
finished motor. I do not really use the grams per length number or
similar as it has no physical meaning to me in my head, I can not
process that unit as I have made motors one way for so many years. I
understand why people use it and I use it indirectly by length and
weight of my finished motor. So when people post grams/meter or similar
I have to find a way to convert that to what makes sense in my head.
Since my rubber stripper has inches of width for the setting not density
I use this chart to get me in the ballpark size I need to set my
stripper to not waste rubber. Then I adjust as needed. The chart is just
a reference. I still sort my bulk rubber by cut width then if the weight
is too light then I used a wider width. .049" 5/99 or .054" wide 5/99
has better meaning to me than 1.3 gr/meter. I know if I make a loop of
.049 5/99 and it is too light and a loop of .054 is to oheavy then I
know to set my cutter to .051 or .052. If I have a loop 1.3gr/meter
density and 1.5 gr/meter density, I have no idea how to set my cutter to
get 1.4gr/meter. I do know how to set for .052" wide.
We all have our own methods. Just wanted to get Vlad an idea as he and I
flew together a lot back in the day and I am willing to bet the gr/meter
thing is messing with his head a little like mine :-)
