I have had an old BECON drill hanging around in the 'round tooit' box for years.
I inherited this German made two-speed hand drill with a box of tools from my father and remember getting into trouble from my father for playing with this in the early 1960's so it has been around the block a few times.
From what I have found around the net it looks to have been marketed under several names, this version being BECON - interesting to see the Made in Germany stamps are quite hard to find and not on the nameplate.

This had a roll pin on an internal gear sheared (hard to imagine you could do that using a handle) so it has only had the low speed drive functional for quite a long time by the look of it. The main issue however was the jaws of the chuck were rattling around inside the chuck having been pushed back in and away from the retaining springs. I tried to get them lined up through the front of the chuck but that was just not possible.
To complicate things the two halves of the chuck were so tight I started to think they must have been pressed together - this was what originally relegated this to the 'round tooit' box.
Previous attempts to grip the lower part of the chuck in the vice resulted in bruises to the lower chuck body as there is only about 3mm of the lower body to grip and obviously the path to tears if I persisted.
This time I decided to try and make a sort of soft jaw by machining a close fitting hole in a piece of steel with a slit cut in one side to give the vice a really good grip for almost the full circumference of the chuck.

A little bit of heat for good measure, some rubber under the chain type vice grips to avoid damage to the knurling and success!

A bit of a clean-up to remove some ancient grease from inside the chuck, re-fit the springs to the jaws and reassemble and it is now back to being usable.
The jaws are in incredible condition given its age but I guess it would be really hard to spin a drill too badly in a chuck by hand.

This is a beautiful hand drill to use and while I probably won't use it often I'm sure it will be useful at times.
