I'm running a workshop on Monday making Marble machines. I'm hoping for a dozen people to turn up and there are a few extra kit requests on top of that so I thought I'd get well prepared in advance and I actually spent most of today making 30 marble machine kits.
My laser has been running pretty much non stop all day. I realise the extreme cold weather has helped my avoid massive temperature increases but also my new cooler has proven it's worth. The water temperature only rose 10 degrees all day.
If you're in or near Northampton then feel free to come and join us for the workshop
