I use a piece of 3/4Ă—3 oak, flat, with a piece of 1/4" ply stapled on the bottom but tucked back in about 3/8. This is a place for chips to go when you're doing multiple operations. The fence is attached by C clamps as needed.
I keep a piece of MDF, larger than the iron table, screwed semipermanently to the table so I can easily clamp to it, rather than fussing with the webbing of the table.
No brag, just fact: I have seven drill presses, 5 dedicated, two not, the latter of which get the above treatment. I don't think this makes me any kind of expert on DPs, just a hoarder.
Kindly,
Lee
