Brain collapse
« on: September 18, 2013, 09:12:00 AM »
Sometimes this old brain stops working so help me out. I have made some tapered laminates that are 34" long, 90 thousand of an inch at the thickest end and 50 at the thin end. Will that mean a taper rate of 1,18 thousand of an inch per running inch?
If that is correct I will be making a RD bow with that taper. Thanks  Bue-- (moroon)   :knothead:

I got .001176 per inch taper.... rounded to 1.2 thousandths per inch

I would write that lam in my records as...

.090 x (width) x 34" tapered .0012/1"

90-50/34 = thousands taper per inch
   40/34 = 1.176thousands/inch

so .001176"/" as stated above.
