And that camera crashes when resized. I need to pick up an 80kg tool off
the stepladder I'll use to access the rear usb-2 sockets and change to
the newer camera on that machine. But I've been busy with 2 other
projects today. Not done yet, my lathe is makeing a hub for a 3d printed
timeing belt sprocket & has hours to go yet.
And I've rx'd a message from one of my sons who will arrive with his main
squeeze tomorrow, so I may be busy tomorrow too. No clue how long they
will stay, but I know he's up to his gonads with a large car, pulling a
triple dump powder wagon full of Portland Cement for his states highway
maint. dept. Haven't seen them in about 5 years, so there will be some
catchup to do. He bought a whole town in Kansas from Fanny Mae, who
wanted shed of it for an off key song, so there'll be pix to look at, at
length etc.
