want to build a pinic table that sits 10 people

Google:

How wide are their asses? This is critical to know if your wife's family will all be sitting on one side of the table.

These simple styles are going to be an awfully long thin bench, if they seat 10. How about going circular, or (more easily) a hexagon, octagon or decagon?

Try this:

Alternatively, as someone else suggested, the octgo...octgert...octogoganl...the 8 sided table might also work.

You owe me a cappuccino and a professional key-board/monitor cleaning.

Well, it looks like you have one nearby that you can look at closely. Try taking picures of it from the appropriate angles and print them onto graph paper. Scale it to whatever dimensions you'd like and use that as your plan. This is a text only NG, BTW, if you want to post pix you'll get less flack if you post to news:alt.binaries.pictures.woodworking, it's designed to display pictures. Lots of ISPs won't show pictures in a non-pictures NG, they'll just filter them out.
