Well, look what found its way to Hoppers House of Engineering Horrors today. I ended up giving the guy his 100 Quid's worth of local beer tokens for it, after my mate checked it out for me and declared it salvageable. I was not so sure when I picked it up. It is really pretty 'orrible in its 'orribleness.
A crying shame to see such a fine piece of equipment allowed to get to that state. The tropical climate does terrible things to machinery. It came from up on the Atherton Tablelands where they get about 6 feet of rain a year and most farmers keep their gear in open sided sheds to catch the cooling breezes, which bring the rain in with them unfortunately. But I think we will be able to restore it to useable condition. Somebody has to!
I thought about putting Evaporust on it, someting I have not tried before. But our local "SuperCheap" auto parts store charges $40 (20 Quid) for 1 litre, so I rapidly rethought that one. SuperCheap in name but not super cheap in nature. So it is spending the night soaking in degreaser in my parts washer and we will see what we have in the morning when all the gunge is removed.
So far, nothing on it moves, but I have not tried more than a casual flick of the wrist. The main handle will turn under pressure but very stiff so I left that alone until it can be soaked in degreaser then WD40 etc. Vertical slide screw seems stuck solid in that Mazak feed nut. Could be electrolytic corrosion there perhaps. And the visible bit of the screw looks pretty ugly.
It only has one indexing plate, the number of hole circles ranging from 32 to 91. So I might make the other two or three to complete the set out of 6mm aluminium plate. Easier to cut out into circles and easier to drill the needed 600 or so holes in.
But right now I am busy with a major motorbike project taking up most of my limited shed time so this might be a longer term project in dribs and drabs when I want a break from bike work.
