Topic: Scale

[Bob Garner]

I'm not sure if I understand your question but I think the graduations for the scales: 4" =1' and 2"=1' are not made up of whole number graduations.  Does that make sense?

In order to make something perfectly clear, I usually confuse the issue.

Yes it makes sense... sort of.  What are the graduations then?

Guys, he's looking for the "groups" of graduations shown on the scale; the "1', 2'6", 5' and 10' or 1', 2', 4', 8' graduations.  The old standard I used to use a couple decades ago was base 2 for Arch. scales (smallest block was 1/8" actual) and base 10 for engineering scales (1/5 inch actual) the graphs were always kept near 2" long.

For 1/4"=1'-0"  You have a mark @ 0, 1'-0", 2'-0", 4'-0" and 8'-0"
for 1" = 10'      You have a mark @ 0, 1', 5', 10' and 20'

But that was a long long time ago.

Yeah, Randy, that's what I was tryin' to say.
