Just wanted to share a recent job I completed using standard lab equipment.
Rx
OD -27.00-6.00x180
OS -27.00-3.00x180
I was able to achieve this RX by using a standard 1.67 blank. I processed minus base curve first then BTC-CC with a +7.00 carrier cut. To my surprise I was able to edge using a 7E. Finish layout markings on Humphrey Auto Lensometer. Geometric center blocking for finish with the edger providing decentration to maintain a parallel or flat chucking in edger which aided in final bevel placement. Final roll achieved by hand edging.
