Excellent, Nobby

Did you find that the drill head bearings would have benefitted from an outrigger support?

I realise your drill is quite chunky to start with

Are you using a drawbar?

Thank you for your posting

HI Bob
I have no need support I have now draw bar as all my holders I have made screw on . Using this gismo As you can see its held on with that long screw into the insert that fits into the drift slot. You can have a look at my album  No Draw bar just click on photo at the side

That was clever, Nobby.......Using the Drift space for the nut location!

Some South Bend drilling machines were advertised as being suitable for light milling. Accessory spindles were available to hold milling cutters. The spindle could be changed by removing the name plate and slackening a screw. Dave

I'ts a sure way to ruin a drill press. Drill press spindles are not designed to cope with the large radial loads that milling generates, simple as that ! X Y tables when fitted to drill press tables are fine for coordinate drilling of holes. The spindle bearings wouldn't cope with anything but the lightest of milling. There is a big difference in the bearings of a milling machine and those in a drill press. At the end of the day it's your drill press.

That's why I suggested an outrigger bearing assembly

My take :- Pillar drills are good for drilling , Mill / Drills are good for milling AND drilling. I have both - that is mainly for the convenience of having the ability to drill a hole without disturbing a set-up on the mill. As has been previously posted it is dangerous to make intermittent milling cuts on a drill in case the taper on the chuck is released - you can imagine the likely consequences of that! The milling chuck, containing the cutter in a collet, is securely retained in the spindle by a drawbar. All this aside the Mill/drill is a much beefier machine than the usual drilling machine.
