Has anyone made this sort of thing ?
Sorry I don't know the technical name for it nor do I have any pictures to show .
It is a wobble-ator ??
A device that sits in the chuck of a drill press and as it rotates it penes a hollow rivet over to close up two strips of metal or to pene over a hollow ended stud .
One of my older neighbors came over today along with his older brother all flustered and embarrassed, they had been trying to move an upright freezer and something went " Pop! " .
On laying on the floor they found a broken plastic adjusting/ leveling foot .. thinking that all they had to do was to undo the threaded bolt that was showing they put a pair of mole grips on it and tore it in half ..the thread was not a bolt but a pened over captive stud. The plastic adjuster simply screwed up or down the 18 mm long stud to make the adjustments .
They managed to get the mounting bracket ( also the door hinge bracket ) off once they'd tilted the freezer back to lay it against the kitchen table
I turned up a new stud in free cutting Mild steel , a 3 mm shoulder in the middle , hollow one end , threaded the other end & also made a new aluminium foot to screw on the captive stud . But it didn't have quite enough hollow end to spread the hollow with a purpose made punch to ensure real good tight join under all circumstances .
So I gave it a bit of 1.5 mm arc rodding @ 95 amps as well , then ground the raised mound back so it didn't interfere with the refitting of the bracket to the freezer.
It was then that I had the Ah AH ! moment .
I've seen these rotating wobble-ators numerous times used in small equipment assembly being done in various factories around the world on The Discovery Channel in such programmes such as " How do they do it? "
Has anyone made them or know how they work internally and where I can see any drawings or generally can offer some sound advice about them please?
For some reason ( not sure why ) , I keep thinking it's going to be similar to one of the wobbling / vibrating square hole cutter devices that you can put on a lathe or in a mill /drill press.
