L/W = 1.155 T/W = 0.496 T/L = 0.430
P/W = 0.485 C/W = 0.321
H/W = (P+C)/W+0.02 = 0.826
P/H = 0.587 C/H = 0.389
Vol./W^3 = 0.343
Addition # 3 - This is not hard really, but you will probably have the cut the steps a couple of times to get the spacing right. This design is deep and works great for lighter pieces of rough, 2-18cts. Cut in refractive indexes 1.62 to 1.93 (85.7%) with no changes.
