After I added an auxiliary table to my drill press, I wasn’t able to use the hold-down clamps that mounted to the original, slotted metal table. Since the auxiliary table has T-track, I made adapters that mount to the bottom of clamps and hold-downs.
To make them, cut a T-shaped hardwood block 35⁄8" long by 13⁄8" wide (drawing below). Then drill a counterbored hole for the clamp’s bolt, a washer, and lock nut. A hole in each leg of the “T” is for a flange bolt that secures the adapter to the T-track. With the adapter complete, you’ll need to securely fasten the clamp to the block first. Then use two flange bolts and knobs to fasten the adapter and clamp assembly to the T-track. Now I have a way to adapt accessories that were designed for slotted steel tables on my drill press table.
