As I was restoring my Delta DP 220 Drill Press, I was unable to find affordable replacement quill bearings, and came up with a usable replacement. I went ahead and made a few extra sets for anyone running into the same problem. There is a NOS supply out there at 69.95 each. I am selling my replacements - Two for 49.95 I can be reached by email at jimliechty@yahoo.com
