Centuri Satellite 62SL Build Part 2 Antenna Mounts

I used a glue stick to adhere the Antenna Mounts to the thick mat board.

You can get mat board scraps at most framing stores. Sometime they will give it to you for free. The mat board also makes great centering rings.

I used the black print to cut the mat board to size.
With a new knife it cut pretty easily, just keep your blade at a 90 degree angle, straight up!

It's hard to keep the knife blade perpendicular.
Keep it straight now or you'll have to square it up the edges later.

Here I'm sanding one edge square with 220 grit on a block.
