ATM hogging out experience

["alderlie" <alderliesten.atelier@worldonline.nl>]

It took me five hours with 60+ACM- to deep out a 16 inch F6 mirror, sagitta 4mm,
I did use a steel ring, 5 inch size and weld a 2.5 kg weight on it.
The thicknes of the steel ring is 6mm, I did round the rim.

If I could do it over again I would use a 6 ore 7 inch ring, so you don't
have to hang over to reach the sides of the mirror.

Grids only 15 minutes a time, with a lot of strength,
center over center with straight lines. Why only 15 minutes? I,am not strong
at all, and couldn't keep it up longer.

Before every new wet, I removed all the mud , and did start with fresh 60+ACM-.

Hope it will help some body,
Kees
