Ok I read that your 6 sides will each be 2" long. This will result in
a
hexagon being 3- 7/16" wide if measured from side to side and 4" wide
if
measured from point to point.
Sounds right.

The quantity coming from 2, 4x8 sheets of 3/4" MDF does not matter. I
would
supply the materials as your shipping cost to me would probably cost
more
than the materials.
Would definitely expect you to purchase the two 4X8 sheets locally wherever you are. How many hexes of the size indicated can you get from two 4X8 sheets?

I can cut the pieces to be the required measurements verified with a
ruler.
Do you have the computerized router?

Sand the hexes? What for? Sanding will make them unequal in size.
The hexes will be handled by users so I was thinking that sanding would be needed so that nobody gets a splinter.

How much to produce? You need to tell me how many you want.
The maximum number that can be produced from two 4X8 sheets.

How much to ship? Again I need to know what quantity I am shipping.
Thanks for your patience.
