Mating a drillchuck to an arbor

[Clive HartlandParticipant @clivehartland94829]

I am about to fit a fit a B16 arbor to a keyless drill chuck, what should I look out for?

Don't quite understand your problem, but maybe check that the chuck also has B16 taper (and not one of the Jacobs tapers).

Clive,

About the only precaution is to check that the arbor runs true before you glue it into the chuck, rather than find out afterwards.

Hi
To check if they are same .with finger put on some high spot blue and gently fit the arbor into the chuck and
See how it touches. MY son was a fitter in the RAF and he sugested to his dad on a job like this use a black felt tip pen and when dry try as i said with the high spot

I ask because I have previously had a problem with a smaller chuck that would not stay on the arbor, even though the taper showed no fault when blued and offered up. It was finally fixed by knocking it onto the arbor with a hide mallet.

Degrease arbor and chuck, than place the arbor in the fridge for a while to obtain a better grip. Niko.

This worked for me once.

Clive,

That worked well for me, after taking advice from a local club member.

In the old days when we used to replace CI valve guides in car engines, we knocked out the old, but put the new ones in the freezer, made a depth guage and merely placed the new ones. Worked a treat, no hammering and always in the right place.

Thanks for all the info, I will freeze the arbor and do it that way.

HI Guy's …I've a few old drill press's bought used and the chuck's used to work loose after a while….

I used 222 Locktight or screw – lock to keep them together…..clean the chuck and its mating face…just a couple of drops of the fluid, hand fit…spin to check for run out…once ur satisfied place a block of wood under the chuck and hang a weight on the operation arm to keep the chuck tight…overnight shoud do it……one of mine was real bad, had tram lines in it, used a little extra fine valve grinding paste to lap it in, a good clean up and Locktite…it's never come of…….only do this if u'll never want the chuck off again say for say MT drill bits….
