Dedicated Drill Press

Very nice machine. Can it tap? I'd love that right now.

Trying the picture again.

Following up on this project with some changes to the table.

500 tables in Drill Press Mode need additional support. I started with the simplest approach by using the extension table as a table support as shown in the picture above. This makes it hard to adjust the table position forward and back using the Table Height Adjustment because the table trunnions interfere with the wide top of the extension table. To adjust the table position you have to lower the extension table then move the table into place, then raise the extension table again until it stops against something. And then you have to re-level the table if you want your holes to be vertical.

To take care of this I pulled the legs from the extension table by heating the aluminum table bracket with a heat gun and knocking the tubes out. I then drilled through both tubes and joined them with a piece of 5/8" threaded rod. 5/8" rod was the ideal size to use because I already had some.

At the top of the tubes I inserted Load Transfer Ball Bearings. These came from Amazon, $16.99/dozen. The bearing bodies are supported on top of the tubes by their own flange but the diameter of the bearing body under the flange is slightly less than the inside diameter of the extension tubes so I wrapped electrical tape around them until they fit snugly in the tubes.

Then I added two blocks of 1" HDPE under the table top to fit into the recessed of the underside. The blocks were slotted to fit with the table stiffeners cast into the underside. 1" HDPE was the ideal material to use because I already had some. It's old and picked up some stains but still smooth. The blocks are attached with wood screws driven through countersunk holes on the top.

Once I raise the extension tubes and level the table it can be moved forward and back and the HDPE blocks will slide over the transfer bearings and the table stays level. The blocks are long enough to allow the full range of forward and back table movement.

Finally I moved the Table Height Adjustment lever and lock to the right side so the lever won't interfere with the table or fence. I still have to move the Carriage Lock to the right side because it's where I keep reaching for first.

I still have to do a big leg swap among the machines, and a bunch of cleaning and touch up paint scratches, but I'm using the drill press a lot for wood, metal, and plastic and these changes have just made it better. I'm heading toward using it for routing and light machining as well.

Here are the table support tubes in position with bearings on top up against the HDPE blocks:

Well I finally got the #3 Shopsmith that I bought several months ago, a 510 out of the storage and cleaned it up and then move the table and headstock to the shorty that I had set up with an old Mark V table and head stock. Took the Old Mark V and made a dedicated drill press. Following edma194 sample and am currently using the extension table as support. I think I am going to go ahead and do the HDPE blocks and load transfer bearings. I also added my Woodpeckers DP-PRO Drill press table that I had on my old benchtop drill press. Had to do a little cutting of the back to get it to fit around the bench tubes.

Woodpeckers DP-PRO Drill press table is expensive. What makes it worth the money to you?

How are you going to manage raising and lowering the table?

How are you going to manage raising and lowering the table?

Or tilt it?

[edma194]

The drawer under the table is a nice idea. If it's attached to the original table that provides your tilt and you raise it like you would the regular table. If you want better raising and tilting capability you can see how I added horizontal way tubes to my drill press and mounted a table carriage on them in this thread: viewtopic.php?p=306089#p306089

I looked at them for awhile, especially for the fence and dust collection for my old drill press. Wife ended up getting it for christmas for me. I do like it. The dust collection on the fence is really good.

The Woodpeckers table does attach to the shopsmith table. It adds a little weight but not too bad. If I need to take it off, it is 4 nuts and bolts so not a super hard process.
