I have a 12" OD x 1/8" thick wall diameter tube. I am trying to find a way to route a small channel 1/8" deep by 1/8" wide 12 diameter in a 3/8" acrylic sheet to set and glue the tube into. I have access to shapers and routers, but for some reason, how to get it perfect is eluding me. Because it is only 1/8" thick, I think it is really important to get that channel perfect so it can seal on three sides (bottom, OD, ID).

I had also thought about making a 11 7/8" acrylic circle to insert into the bottom of the tube, glue (weld-on #4 or maybe #16) the piece in the bottom of the tube, then glue the whole assembly to a flat acrylic sheet.

I am making a monster skimmer. Thanks for the help.
