Thanks Eric and Jacqueline.   Presently for everything up to 12" I  
have been using a VPI HW17 and various solutions but for the larger  
disks it was though to stick them on the 16" turntable and dab on the  
liquid (scientific terms here) but the drying is an issue.  Thanks for  
the tip re Keith Monks... I will also follow that up as well.

Could you give more information about your platters for Keith Monks  
machines (and if you are selling any.. just in case they are needed  
(the platters that is).

Many thanks, Darren
