Stop in for a cup of coffee

yeah, i wanna do my own alignment.. don't wanna blow $200 on turnplates.. there are ways to make ones at home, i need to get on that.. winter is coming
I bought a sheet of white plastic stuff, polyethelyne i think. Cut it in 12” squares out of 1/2 of the sheet, two pieces with grease in between. I can slide cars on them easily. Could have likely got by without grease.
