Yes, this. Do not put a cutting wheel on a drill press directly. The spindle is not configured for side loads and could pop right out, and you will not have a good time. In this case, there is a heavy-duty arbor supporting the cut-off wheel from below (under the tarp), and the drill is only providing the torque from above, with a double-U joint to compensate for misalignments.

Mostly I do lapidary work, not metal. I don't have the space to set up a flat lap machine, so I put a lot of effort into adding that function to my drill press. Sturdy base, strong motor, already taking up space. Got Covington Engineering to make me a custom arbor by assembling one of their standard ones upside down, so the wheel mounting flange is on the same side as the housing support flange. Pressed a sleeve bushing onto the housing to raise the diameter slightly, and I can swap it out with the table on my drill press with a secure fit. Couples to the drill with a Lovejoy DD3 double U-joint. (The bottom of it was drilled and tapped to fit the arbor, the top gets chucked into the drill.) Typically used for grinding, sanding, and polishing stone, inside a tub with a constant water spray. I took that apart to jury-rig the saw. Only new thing I bought here was the tarp.

OH HEY! I was doing some searching... if you can add one of these things between two washers, you may get some swivel action out of it: http://www.amazon.com/Koyo-FNT-821-Bearing-Capacity-1-43lbf/dp/B007EE5PT6/ref=pd_sim_sbs_indust_4?ie=UTF8&refRID=1E1V6WK0PQMN0PX1XJHQ

Ratchet with spring loaded pawls? There will be minor backlash, and they do make those one way bearings even smaller, a 0.5 in ID one weighed 0.05 lbs.

Stock bearing size: 1/4" ID x 1/2" OD x 0.0500" thick. (measured bearing at 0.2535" ID x 0.4880" OD x 0.0500" thickness, blade cutout OD at 0.5220" and pivot at 0.2485")

Washers used: TT-504 Oil impregnated bronze thrust washers.

Washer size: 1/4" ID x 1/2" OD x 1/16" thick.

The correct thickness is 0.0480 for both washers, and it is very important to keep them as flat as possible. I ruined 4 washers by sanding them and finding out they were 0.0015" off between each side. These are within 0.0005" flatness.
