Kind of disappointed that Warmfire never came back to enlighten us.
I am glad for the comments and links for opening up ideas. I watched that table video 2 times and realized I can make one myself as I have a round table that turns on my drill press. Place the cast iron table on center as close as you can and lock it in place. Place a piece of wood on the table the same dia. of your table. Clamp it or pin it so it can not move. drill a hole through the wood on center ( I used a 1/2 inch bit). I then removed the wood table and set a router with a 1/2 inch v-cutter fitting in the center hole. Clamp a straight edge on the wood to make a straight 1/2 inch v- groove across the wood table right through the center.
You now have a v-grove for round stock just like the one for sale! the layout for those holes on the table are made by simply rotating the swing support on the column. be careful not to drill into the metal original table. Works great on my 14 inch bench drill and by removing the wood top I can set it aside for future use and simply align up that 1/2 inch hole with a 1/2 inch drill or pin. Clamp and back into center drilling. All DIY and cost basically free. This setup can work the same with a square table but the table itself will not rotate but the column support will.
I say thanks to all for comments and suggestions.
