Fitted the top , feet and added rubber fillets to hold the panels in. |

A bit more fiddling today. I've wired a control box with no-volt switch and psu for the speed adjustment motor. I going to have to pull the kopp apart and clean out some debris, I noticed that since changing orientation,it has developed a click (the adjustment worm bearing show noticeable wear and I suspect crap from this has got into the mechanism. Changing oil didn't shift it.) And I have a oil leak from the speed adjustment port. It'll be easier to make a motor driven speed change with it on the bench |

(I did have a flexible drive for the speed change knob so you could operate it remotely but don't know where it is - or even if I still have it.) |

Cheers Phil, I'm sure it'll only need a clean I was fine until I ran it on its side. When I swapped the bungs the magnetic one was quite furry , so there is sludge in there. Vill |

Well, that was instructive. 1, they are not difficult to take apart. 2, the largest piece of debris was a flake of paint (thst probably fell in when I opened it). 3, there is no perceivable wear , it's like new inside. 4, they are fiddly f####rs to put back together! Still , I have fixed the leak And decided the click is the motor coupling, which I may have to change along with the motor, as it lacks starting torque for the highest speeds. |
