hi Rob.
I will post something soon, but progress has been slow. My lab is currently shut down until Monday - I share the building with another company, specifically share the kitchen and the toilets. The other complany make roller blinds and curtains -they have just been having a couple of staff in for 1 or 2 days a week. A few weeks ago they got a big order, and all came back to work. By Friday 5th around half of them (4)they went down with Covid, and the landlord asked to close the building for a cooling off period and a deep clean, especially since in the (partly connected) adjacent building there are another 15 people working pretty much 24/7 on food distribution logistics.
