Ralph Whitaker Posted April 28, 2022 Author Report Share Posted April 28, 2022 17 hours ago, Charlie D said: John, I think Ralph is implying that you grip the wrench in the vice so that you pull it horizontally with the spring balance, so the weight of the handle does not upset the reading. (As Waldi mentioned.) Charlie. Spot on Charlie, that`s exactly what I do. Might see if I can blag a large weight though and do the hanging method in case my spring balance is not reading correctly. It is one bought from a fishing tackle shop for weighing your catch, goes up to 50lbs. Ralph Quote Link to post Share on other sites

It is gently wound around the base of the stud and when the washer and nut squeeze down it makes a good fluid seal. Roger Do we know a source for this lead linger? It just so happens that I do have an oil weep from the oil pressure adjuster as Stuart said. Ralph Quote Link to post Share on other sites

In which case, a spring balance would be necessary to exert a measured torque on the wrench. But IMHO the weight of the handle is trivial. John PS Just checked my own and weighed the wrench itself. 2.5lbs, so you can add that to the test weight, or IMHO ignore it. Quote Link to post Share on other sites

I would use a drop of liquid PTFE on the thread as you screw it in. Stuart. Quote Link to post Share on other sites

Exactly John, if the COG (say half the length of the wrench) is about 1’, the error is 1 ft.lbs, so very small. Cheers, Waldi Quote Link to post Share on other sites

Ralph I believe it's just soft lead wire, which is often used by scale modellers and available here: https://www.scalemodelshop.co.uk/search/accessories-c4/metals-c228/lead-wire-c286/lead-wire Pete Quote Link to post Share on other sites
Ian Vincent Posted April 28, 2022 Report Share Posted April 28, 2022 FWIW, I have used some Code 4 lead flashing to make a lead washer for my oil pressure adjuster. I also used it to make washers that sit under any earth connections to the bodywork. It prevents corrosion whilst making a good connection. Rgds Ian Quote Link to post Share on other sites
