Good day
When I had to drill wheels (knobs) and small parts, I used hold-down clamps and other combinations that where "big" on the small wheels...but, no more...
The idea came from other shop-aid that I made for cutting small pieces on the table saw...so, why not on the Drill-Press.
So now, the DP table is clean from all the clamps and hold-downs and here it is...
Best Regards
