[quote="JPG40504"]Do you know where I can get a magnifying glass? - At least it all fits!]
Just increase the size to 200%, then ya might be able to read it.

As I understand it you are asking for feedback on your chart and its usability.
With that as my goal...
I love the idea and it is obvious a lot of thought and effort went into the chart. There is a HUGE amount of great data here but...
My old eyes cant read it. It would be a much better effort for me (I know you made it for you not me:D) if it were in a larger font even if it ended up spread over a couple of pages. Or the front and back of one page that could then be laminated and hung on the wall above or even attached to the tool where I expected to make the most use of it.
Just my thoughts, you did ask:o

Print it out greater than 100% size.
Thanks for the input - here's the second part

Still a work in progress so I will take your ideas and continue. It's now cleaned up and just a tad larger.
The second half is specifically for the ProPlanner upgrade is a speed/feed chart.
You can find the pdf here =>

PS - Understand this is meant to be a quick reference only. Also I removed th s off of http so you shouldn't see the security certificate error.

After bypassing my security (computer claimed the site had a certificate error) I was able to view the site.
Lot of work here and that is to be admired!:) It is a large compilation and gives a good general idea of hardness of many species.
However, given the numbers, I was unable to tell if hardness is expressed in pounds/sq inch or other. Also, I would want to know if the chart addresses wood of what moisture content, is it speaking of compression hardness, shearing hardness, and is this table a combination of the above.
Does the table address hardness perpendicular to grain or other. Most tools cut into wood at a shearing angle. It's pretty hard to cut perpendicular to the grain. I believe most woodworkers don't really care about how many pounds of pressure or strike will crush wood. I think they just care about is one species generally harder than another.
If all one wants a table of how easily a ball pien hammer will leave a dent in a dried wood board, then we don't need a table with pounds - all we need is the colors.
If we desire more precise information, then Chapter 5 (Mechanical Properties of Wood) in the "Wood Handbook" will give those precise numbers.

Then id does not fit on a 'page' or single sheet of paper so formatting is lost.
If it were available as a spread sheet self formatting and alignment would be possible.
