Re: [CAD_CAM_EDM_DRO] Re: Usefull Utility

I'd love to share a spreadsheet for this but I don't have one and I wouldn't
use a spreadsheet for drawing a sprocket. I'd use a CAD program.

If you will please read what I wrote again, but a bit more carefully this
time:

"Sprockets are so simple to draw, (see Machinery's Handbook) they can easily
be drawn in any decent CAD program."

you'll see I said to use a CAD program for the sprocket DRAWINGS.

Most formulas are (to me anyway) so simple that I don't need a spreadsheet.
I would only use them if I wanted to make comparisons for some reason or
other. Most of the time I do formulas in my head, using a calculator and
sometimes a penciled sketch as aides. This is a lot faster (for me) than
going to the computer, opening the program, opening the right file and
entering the data.

For the sprocket DRAWINGS:
All you need to do is look up the sprocket tooth profile and its associated
chart in Machinery's Handbook, draw one tooth for the chain size desired,
copy and paste as many times as required for the number of teeth desired for
your sprocket.
