The progress has been slow,
Over the weekend I finally made a new plywood lid for the cooler mash tun, I am experimenting on the cooler before doing anything on my kegs.
I have to admit that after I had cut two plywood circles, one to fit in the tun so the lid doesn't slip, it was very difficult to cut them to make sure I can remove 1/3 of it to add grain or just to take a peak inside the tun.
Finally was able to get a windshield wiper motor, my neighbor is a mechanic !
Now lets see if I can make it all work.
