I built the custom drill press table using the commercial plan purchased at http://woodstore.woodmall.com/drilprestab.html. The plan is a paper plan and superb quality.  I had to adapt it for use with my round drill press table. The T-track beneath the custom table was changed to run front-to-back, rather than side-to-side. This worked out well. In use, I have found a need to be able to clamp closer to the center of the table for small pieces. I will add some T-track near the center to accommodate this requirement. The table is built with 3/4" Baltic Birch plywood and finished with Minwax marine spar varnish. The table has greatly increased the ease of use of my drill press.

Late Flash! I've updated the table with added T-track and a sacrificial center section. See the last photograph on the page.

Overview of custom built drill press table

Left end view of custom table

Clamps used on custom table

These clamps are very verstatile when used with extra long (6") threaded hex bolts. Note the use of scrap wood to support one side of clamp.

Front view of custom table

This shows how the clamps are mounted. A planned enhancement is to add T-track near the middle of the table so the clamps can operate closer to the drill bit.

Mounting underneath drill table

Two bolts secure the custom table to the metal drill press table.

Under table mounting with T-track

Two T-tracks are mounted under the table leading from front to back. This provides additional positioning flexibility for use of the side fence on the custom table.

Horizontal fence

This shows how the horizontal fence is mounted to T-track to allow easy adjustment. Note the semi-circular cutout in the fence to provide added clearance for the chuck when drilling.

Another view of the clamp

This shows another view of the clamps used on the custom table. I bought these clamps at a woodworking show. They can be purchased at www.rockler.com, if you like blue clamps.

Using the vertical fence

This shows how the vertical fence is used. Note use of the adjustable glue clamp to secure the piece. A strong clamp is needed to withstand the downward pressure from the drilling operation. Note how the metal table is rotated to the right and the custom table position is changed using the under table mounting bolts.

Vertical boring operation

This hole was drilled using the vertical fence. It is actually about 2 inches deep.

Newly added T-track and center plate

I added two additional T-tracks (red) to facilitate clamping close to the center of the table. This works very well. The area between the new T-track is now a piece of 1/2" MDF. It is a press fit (no glue or screws) and can be simply replaced. I cut it out on my table saw and did final trimming with a few passes of a jack plane to fit it snugly.
