    My latest addition is this mint (unfired on arrival) Hank Roberts Mini stove and an adaptor from a US ebay seller allowing the use of modern gas cartridges. Less than ideal I know but lacking John's @presscall silbrazing skills (or spare clock holes) it may have to do.
    For anyone wanting to see John's ingenious solution to jets as small as 0.23mm without using micro drills here's a link

    The thought of using micro drills as small as 0.23mm doesn't fill me with joy but if I do I'll post results.

    @Robert Radcliffe A heads up! Might not be ‘turbo-powered’ Robert but the flame looks mighty healthy.

    @Majicwrench I'll post my own adaptor efforts at some point. It was 4mm by 2.5mm pneumatic tubing pushed inside 6mm by 4mm tubing to attach to the HR stove nozzle. It wasn't quite tight enough to completely seal to the nozzle by friction alone and had I not known the purchased adaptor was inbound I'd have probably glued it in place.

    Here we go. I saw this on a You Tube video created by a Thai stove collector and he confirmed the tube dimensions I used. It seemed to work well for him but the inner diameter of 2.5mm is still to large to make a tight enough fit to the HR nozzle. 2mm would be better.

    The ebay purchased adaptor uses a stack of three o rings size 103 buna-N-70A. It is a far tighter fit.

    Yes I was pleasantly surprised John. Another reason I'm not rushing to make any attempts at drilling the jet.

    What made you think you might need to mod the jet, Robert?

    Like @Ian , I am too wondering......

    I used a similar hose like pictured above in an early effort, it was hose for those little engines that power model planes. Very heat resistant and fit well.

    @Ian @Majicwrench it was after reading how John modded his HR clone to get it to burn well with modern isobutane cartridges. Larger jet and bored out air intake holes.
    I think John was trying to get a burn similar to a HR using the original gas canister with a wick.

    I don't think you need to do anything to stove, mine works really well with no modifications.
    Modifying jet or air intake, IMHO, would not be a good idea.

    Hank Roberts stoves are great. I have used mine on motorcycle trips for a few decades now. About out of containers that can be refilled. The valves go bad after awhile. I'll have to get an adapter. Good news they are available.

    @Majicwrench yes I'm not intending to alter it. I'd quite like the lantern next.
