i can't believe dee ann has so many dishes... that's incredible. lotta learning in a back yard. i would trip over one to adjust another... if i can figure out how to post these pictures i will try to get my two dishes posted. charlie
Dee_Ann,
For the purposes of this note it would be a good idea to be out at the dish while reading this.
On the pictures you have posted there is an “upper scale” and a “lower scale”. The lower scale is the one with the numbers 0-9.
For simplicity sake consider that the “pointer” to be used to set the dish is the line with the number “0” on the lower scale.
So, if you wished to set the dish at 40 degrees, you would simply move the dish to where the “0” on the lower scale is pointing to the 40 on the upper scale.
Always use the “0” as the basic pointer. If you wanted to set the dish at 40.5 degrees, you would probably move the scales until you have the “0” pointed about midway between the 40 and the 41 on the upper scale.
For most of your measurements you can use it that way.
What the additional numbers are used for is a little greater degree of accuracy. Because our eyes cannot perfectly divide the distance between the marks on the upper scale in to ten equal parts, you are given the lower scale to be able to accomplish that task.
** you may or may not want to try this:*
Now let’s say you wanted to set your dish to 40.6 degrees. Hmm we know that the “point 6” is a little greater than midway between the 40 and 41 marks but it is very difficult to judge.
So you move the dish until you have the zero “0” pointed midway between the 40 and 41 marks. (if you are exactly at the midway mark, with the “0” you would notice that the “5” on the lower scale would be “exactly” lined up with a mark on the upper scale. (It makes no difference what mark the 5 is lined up with, as long as it is “perfectly” aligned with a mark on the upper scale and the “0”on the lower scale is midway between 40 and 41.
Now, if you wanted to get that measurement of 40.6, you are close and only need to move a little more until the “6” on the lower scale is aligned with a line on the upper scale.
One thing to be noted is that when you have one line on the lower scale perfectly aligned with a line on the upper scale, none of the other lines on the lower scale will be perfectly aligned with the lines on the upper scale. It is designed this way. The lines will be close to being aligned, but only one will be “Perfectly” aligned.
I know it is a little confusing, and I also know I have many machinists pulling out their hair with this explanation, but do hope it helps.

Great reference!That is a vernier scale - here is how to use/read a vernier scale on vernier calipers:

Happy to be of some assistance.The logic behind this system baffles me. I can't imagine what drugs they were taking when they dreamed up this device.
BUT..
Your explanation of HOW TO USE it, is understandable by me...
You managed to explain it in terms simple enough for an ijjit like myself to make use of..
I do now believe that I can muddle my way through this weird measuring system. I suppose if I do this a few times I might get the hang of it.
I'm going to print your post and take it out to the dish and give it a try.
Thank you very much for your help, I needed the most basic, simplistic guidelines to go by and you did a magnificent job of showing me the way..
Happy to be of some assistance.
Actually the system was developed for accurate measurements that could be read with the human eye before we went digital. Imagine scales with tiny lines ten thousandths of an inch apart and trying to discern them with the naked eye. So they developed this way of making it "easier" for us. The thing is that is has a little learning curve.
Good Luck and have a great day.

Hello Dee......I had a conversation the other day( 1month ago) with the woman who has the dish farm I was telling
you about. I told her that we could offer her some cash for a few of the dishes, would she consider it.I let her know if it got cold
outside would be a good time to try to discover just whats out there...(no snakes)...I know how you like those.. She might go for it.
I will stop by there soon and let you know what she says about how much it will take to convince her..
By the way, IF I knew the dish mounts were going to cause you to drink, I would have told you how to use them...LOL...Talk later
