Yup that was the first test on a lathe scrap. I didn't have any endmills then so I used a carbide router bit. Not too bad considering and it certainly was a jump in quality from my usual Fred Flintstone ways.

Unless you can find one of those old drill presses that were made by the Sherman Tank Company you probably won't be satisfied with the conversion because the import drill presses are too light and shake too much when milling. The head casting, though robust looking, is too wiggly. Seriously, save your money and sanity for a mini-mill. If you're determined to go ahead anyway, I've got several unneeded ER-20 straight shank collet chucks (.500" diameter, 6" long shanks) and I'll sell you one cheaper than you can find it anywhere else.
