SPINNING LEARNERS

Technical Spinning Information and Formulas :-   1) Constant  One pound is 7000 grains = 453.59 grams One skein is 120 yards = 109.7 meters One yard = 36 inches = 0.9144 meters One hank is 840 yards = 768.1 meters The yarn count and hank roving number equals the number of hanks in one pound. To find the hank roving number from number of grains per yard: Divide 8.33 by the number of grains per yard. Hank roving number = 8.33 x yard Grains   2) To find the speed of the front roll Divide the revolutions per minute of the spindle by the product of the twist per inch, multiplied by the circumference in inches of the front roll Front roll speed = S pindle R.P.M  diameter of front roll  x  T. P.I   3) To find the Spindle Speed Multiply the R.P.M. of the front roll by the twist per inch and this product by the circumference of the front roll. Spindle speed = FRS   x T.P.I x  X diameter of front roller   4) To find the standard twist per inch Mul...
