Members plusone Posted January 15, 2022 Members Report Posted January 15, 2022 Hi all. Hoping for some advice on fixing this plough gauge up, found it in an antique shop today. No makers mark that I can see, only mark is an inscribed gv, I think this is the old owners initials. while it has lots of wear and needs a good sharpen everything moves except the brass roller. I’m assuming that should be free moving. any tips on how to unstick it? thanks. Quote
Contributing Member fredk Posted January 15, 2022 Contributing Member Report Posted January 15, 2022 If you can get that wing-nut off the end, then the roller unit I'd dunk into some hot oil for a while. Really hot oil, either clean engine oil, diesel, home-heating oil or even home cooking oil. Keep the oil real hot. Eventually the metal will expand enough to allow the oil to get between the bar and roller and allow you to separate them or, is that wing nut just tightened up too much?

Members TomE Posted January 15, 2022 Members Report Posted January 15, 2022 (edited) Spray with Kroil Oil. Wait. Tap on the roller with a plastic mallet. Repeat as needed. Patience is the secret for restoring vintage autos. Can make penetrating oil in larger quantities from a mixture of hydraulic oil and automatic transmission fluid.

MikeRock Posted January 15, 2022 Report Posted January 15, 2022 I used Duck Duck Go to search vintage plough gauges.... what a wonderful rabbit hole to wander around it... Lots of links back to this site as well. Enjoy. God bless Quote
Members dikman Posted January 15, 2022 Members Report Posted January 15, 2022 That looks a bit odd, it appears that the wing nut tightens up hard against the roller?

I use a soldering torch and PB blaster. then drill a hole big enough for the bolt head but not the brass in a piece of flat bar, put a nut on the thread end so you don't mushroom them and add heat and lube then tap the bolt through the hole in the bar with a hammer and flat pin punch.

Members DrmCa Posted January 15, 2022 Members Report Posted January 15, 2022 I do not see any mechanical possibility for the roller to rotate, with the pictured design. If you badly want this to work, you may have to invest into replacement parts. Until you get the formerly winged nut off you won't know. +1 for using heat and WD40 to get it off. Later, you might want to get a replacement steel nut.

Members Squid61 Posted January 16, 2022 Members Report Posted January 16, 2022 I don't see how that could ever have worked as a roller! It must be missing something at the nut end between the roller and guide that allowed it to both tighten and roll. Breaking the roller free needs to be done but that isn't going to make it roll.
