I just got a upright walker turner drill. Its a tall upright floor model. I am going to restore it but I have another one I am using now. I still want to keep it but I would like to set it up for mortising. I was wondering about the Delta attachment kits. The drill I use now is a good workbench top china brand type. I may not even use the mortiser much so I thought about trying the adapter kit on the china made drill. Has anyone set one up on a drill press and can they be adapted for other drills other than Delta?

You will need to accurately measure the diameter of the drill press spindle – the shaft part that gets exposed below the head casting when you pull the handle down. Lower the spindle about 1 inch and lock it in this position, Then carefully measure it’s diameter just above the stop collar. The Delta kit comes with some adapter pieces (1/2 round inserts) that go between the shaft of the drill press and the mortise frame. There are several different sizes of these. All have the same outside diameters, but each pair has a different inside diameter. The ones that, when put together to form a circle, have a slightly smaller inside diameter than the measurement that you took, are the correct ones to use. Place the correct adapters around the spindle shaft just above the stop collar and then install the mortise frame over these adapters and tighten the clamp bolt very well. If you can get this far, then the mortise attachment fits your drill press.

Any drill press with a collar should be able to mount a mortising attachment. Measure yours and make sure the Delta includes adapters that fit.

I bought a kit on sale a while back. It worked fine on a few test pieces, but I have not used it on a real project. One annoying feature is that the unit must be clamped to the drill press post in such a way that it blocks the handle used to raise/lower the table. I need to extend the length of the handle so the table can be adjusted with the unit attached.
