Make the recess before you slice the coaster off.
This was my original though but I was concerne about turning a peice of stock two feet long with only one end secured. I have found larger bits so tyhat may be the bst rout. thanks for the info
Bob,
Turn the diameter, recess, slice, recess, slice etc. Thanks for the idea, sounds like an easy Christmas gift.

Bob,
The recess can easily be made using your router, a bowl and tray router bit, a router template guide, and a shop built jig. The following should be done before cutting the coaster from the turned stock.
Start by drilling a hole to the correct diameter in a rectangular piece of scrap hardwood using a circle cutting bit in your drill press - the hole should be offset to one side of the rectangle. The scrap wood should be large enough to comfortably balance a router around the edges of the hole. Attach another scrap of hardwood to the bottom of the first piece in the uncut offset area. It should be mounted so that the hole is exactly centered over the wood stock to be routed. (See the enclosed graphic)
By clamping the jig to the wood stock, a bowl and tray bit set to the correct depth and guided by a template guide on the router's base, will make short work of the desired recess.
If the jig is clamped onto round stock, shims should be glued onto the clamping block to keep it from rotating.
If you have any questions, please feel free to ask!

Cut them off by parting almost through between centres,then make yourself a shallow jamb chuck with some double sided tape in the bottom and face them up and hollow on the lathe.Get back to me if this is not clear
