Meddings Drill - Troubleshooting wobble/runout

[Dissolve]

Hi Guys,

I got my inverter hooked up today, and I'm really impressed with the setup, it's quiet, smooth and runs extremely well. I've run the drill at a slow speed and I can see a bit of runout/wobble which seems apparent around the whole chuck. It's visible enough to know something needs adjusting.

I am borrowing a drift key to knock the arbor out and take a look. I'm hoping re-seating the arbor will correct the wobble but if not, how do I identify what taper the arbor/chuck accepts? It's a Jacob's chuck and it looks pretty solid (not abused) but does someone know how I can identify what taper's they accept?

If re-seating the arbor does not work, how do I remove the chuck and re-seat that from the arbor? If that fails I will buy a new chuck and arbor to rule that out before digging deeper!

There is no play between the spindle/quill and I'd be surprised if it's been damaged as it looks well looked after.

Cheers!

Morse tapers are pretty easy to identify as each size is quite distinct from the others. Use a chart such as this one and dimension A across the end - if it's half an inch it's no 1, if it's 3/4 it's no 2 etc.
