Just joined after lurking for a very long time.
I have learned a lot from you guys, thank you for all your help.

Added some electronics and motors from China, an Arduino and GRBL and it works...........

OK enough for now, I have to go and fix a leak in the workshop roof before the rain sets in again tomorrow
