    Of course if he clamps a different size pipe they'll be off again.

    We don’t need to see this as we have enough tool abuse in the first and second world countries.

    You might call it abuse, I call it working with you got. The chuck was probably picked up at scrap yard. A new chuck is most likely more than a few month salary for him. If he's working on the same size pipe all the time, then the chuck will probably be good enough.

    My thoughts also. An eminently practical solution, not one that I would adopt but valid none the less.
    As to different size workpieces, those comments apply equally to any method of jaw truing.

    If it works, it works. I had to true 6 jaw glass lathe chucks in the past, the main jaw set was held with a ring at the back of the glass gripping replaceable inner jaws, line ground to true the replaceables they'd be fine, until someone got the torch or main burner too close and distorted them again, our newer glass chucks have one piece jaws, so if overheated it's a whole lot of money to sort those...

    "Glass chuck" Is this a steel/iron chuck to hold glass items or is it a chuck made of glass for some low contamination requirement. It sounds interesting either way.

    Usually stainless steel bodied with various heat resistant materials including Inconel or even Invar used for the clamping sections of the jaws that hold the glass, we have had all s/s one's but they don't work so well.

    What gets really interesting is some glass lathes have two 6 jaw chucks back to back on the working side of the headstock as the 'master' work holders, a further 6 jaw on the outside of the head stock for stability, and one 6 jaw either side of the tail-stock, all are driven from the same motor via toothed belts or gears inside the 'stocks', the tail-stock slides along the bed with a very long splined shaft supplying the rotary drive. The burner sits on a motorised saddle and moves up and down at different speeds to suit the job, with the burner being on for the slow working passes and off/reduced for the return, that's how fibre optic's fibres are made in the 'bulk' before pulling them down into fibre on a tower. Those often have a 6 jaw to hold the 'preform' too.
