Re: File uploaded to Group.

Hi Don,

I'm impressed.

I think it is a GREAT result and you certanly have masterd Excel much
better than I.

If you plan on some tweeks, ACME and all-thread screw powers would
make it fit almost every unit. I think they are just simple
multipliers like 0.6 for ACME and 0.35 for all-thread so some such.

Well Done !

and thanks for your contribution.

Dave
