    Ive had this tool for years but have absolutely no idea what it is for . The end opposite the tommy bar appears to be a screw driver? the internal end is countersunk with a hole through the end of the tool around 1/4” in diameter and it has Pickavant 280 on it. I know some of the members like this type of post and may be able to help. Did wonder if it was for installing spoke nipples but not sure the hole would be large enough? 731C40D4-13C8-40C0-92B2-831031EA6EDA.jpeg 3C9E42E9-6AE9-4B3C-AE7B-29BA822C801B.jpeg

    Crimping tool?
     
  5. I'd go for the tappet suggestion but at first seeing that it was in the kitchen - an apple corer!

    Unlikely , there is no way of releasing a locknut and the screwdriver type end inside is to large to go through the end . The only information I’ve been able to find is it was likely to have been made after 1921 when Pickavant started producing tools and 1968 when the company became Sykes Pickavant.

    I should have used a mug for scale.

    I have some strange tools of similar appearance that was made for servicing Cummins engines so could be part of the same dna

    Is it a hydraulic ram for one of these.

    Not hydraulic, the tommy bar can be pulled away from the main body against spring pressure which moves the screwdriver away from the countersunk hole in the end presumably to insert a screw or nipple, I can’t see any other reason for the countersinking inside. As roofman says it could be and likely is a special service tool for a specific purpose? I can’t even remember for certain where I got it from , may have had it best part of 50 years

    It's for fine-tuning a flux capacitor. :thumbup:

    Photo not particularly clear but the hole inside the end is countersunk
