Clean em up good and get you SIL to set you up.
It is as easy as can be.
You set the press up where it won't be in the way, lol.
And get the biggest set of these you think you can manage. At 3" by 5", I should have picked up bigger plates.
The press should have something that fits this piece. It has screws that hold it in place. The other one, for now, just floats on the work surface below.
Plug & Play.
