Corn bread from popcorn

Hello,
I have an old mill-rite grain grinder that was left to me when my Dad passed away. I have used it to grind popcorn and made corn bread from the corn meal. I've also dried sweet corn from the garden and used it. It makes very good cornbread, and grinds easier than the popcorn. Has anyone else tried this for cornbread? I ask because I've heard you shouldn't use popcorn because it's hard on the grinder. Thanks for any info.

Here is some information on making flour from popcorn and a recipe for Gluten Free Popcorn Bread:

And this flour is not hard on a grinder:

Popcorn flour is a whole grain flour you make yourself – no shopping around at various health food stores to find it! To make it, simply pop your favorite popping corn, then process it in a blender or food processor until the popcorn becomes a fine powder.

Thank you Anne!

Last evening my daughter and I made cornbread from our own popcorn.  She was skeptical, but she and her siblings devoured it.  Here is what I did:
*Note: I measured nothing.
Put a couple of cups worth my homegrown Cherokee Longear popcorn (un-popped) in my coffee grinder, ground it up good.
In a bowl, combined the corn meal/flour that we made with about a tablespoon of baking powder
Added 4 very small eggs (from my hens... "unsellable" because of size), stirred well
Added unsweetened applesauce until texture was "right"
Put in greased glass 8x8 pan
baked at 400 (I think that was what my normal cornbread recipe called for... I'm typing this from memory) for around 25 min

I have some pics on my phone, but I'm terrible about getting pics from phone to computer to upload.  Maybe I'll get ambitious if anyone shows interest.
