Rightio,
A long delay there... I won an eBay auction for the following air compressor for just over £40, but the seller reported it broken and refunded the money. Talking to him he sounded a genuine guy who was going to fix it before handing it over.
This sounded out of line with most eBay auctions, so I sceptical, but because he sounded above board I hung on.
Anyway, today I rang him and went round to collect it.
Seems to be running fine, so I may have found one of the better people on eBay.
So, now the clear acrylic sheet (eBay £31 for a 300mm square sheet at 20mm thick).
And then to begin the search for a vacuum pump!
Any guidance on spec. / advice on what to look for gratefully received.
Honestly... this pump seems to be the hardest thing to find!
What is the reasoning behind recommending the 7CFM+ pump?
I have looked on eBay at a variety of kits (pump and chamber together) and they are often in the region of 2CFM for just under 10 litre pots, and 3CFM for just over 10 litre.
