Ive looked at the Lortone on line now and see that the barrels are sunken into a well, so my reply is not relevant. On my machine, from UKGE the barrel runs on two rods above the motor housing. No matter how you level it, the barrel ends up rubbing against one end-stop or the other.
When I go to Cooksons next week They'll probably have one of yours on show, so I'll have a look at the disks you describe. Regards, Dennis.
