33" f4.1 started into figuring.
Hi grinders,
Been juggling my spare time between my 25"f4.5 and 33"f4.1, (both in relatively early figuring stages).
The 33" came through its polish,, (second time) with the usual artifacts, (for me). A wide "rolled edge" and "large" hole in the center, but fortunately was free from obvious "astigmatism". At the moment have arrived at this figure. Been 9 hours work so far, using 8 1/2" and 17" laps. I know there's still a long way to go.
All work is done by hand. The hardest job is lifting the 95lb hunk of glass,(it was 115lb at the start before "hog"), off and on work block. Still good exercise for an "old bloke",(keeps the muscles right).
