    Default Fixing drill press spring return

    Hi. I was servicing my old H&F pedestal drill and, through a series of mishaps, this spring popped out of its housing. Its actually the return spring which raises the spindle when downward pressure is released.

    Does anyone know how to get it back into its housing?

    All variations of 'hold one end in a vice and use pliers to ... ' have failed, by a long way.

    Photo attached is the spring sitting beside its housing.

    cheers

    Try a large hose clamp. Place the spring in the middle and tighten the hose clamp. Have another smaller hose clamp open slightly larger than the minimum you can squeeze the large one down to so you can push the spring into that, then continue to wind down the second hose clamp etc. You use a pair of narrow nose pliers to give it a "jiggle" now and then to keep the spring contracting. Saw my Uncle use that method.
    Another method was a T bar made out of reo rod with a slit.

    I managed once - and only once - to put such a return spring back by pliers. I hooked the outer hook into the slot, then wound the rest in bit by bit in a sort of spiral motion, until the centre hook - and therefore all of the spring was inside. The outside receiver was however a cast part of the drill press and stayed still easily! A t-bar with slot works fine, as long as the outside receiver can't move.
    Cheers,

    There is a hook on the outer end. Maybe it's just not clear in the photo.

    I am wondering if the inner end is maybe broken, though ?

    Currently it's sitting in my garage in the third size-iteration of hose clamp, waiting for me to buy the fourth. The process is working.

    Cheers

    Have a look at Clickspring's last video where he makes a spring for his clock and does exactly what you want to do
