Step 7: The Base and Post

Now comes that funky base. I had a few options for mounting the base, the photo shows the one I settled on for now. Reassembly is simple, a steel rod slides into the holes and is held in place with a set screw. The post goes into it's hole and there are 2 set screws to hold that. Simple.

I bolted the base to the worktop using the holes that used to bolt to the saw. I then adjusted and levelled the post and tightened the set screws. The post has to run that far through the base in order to keep it level. Not the best solution perhaps, but it does work.

The table slides down the post and the clamp handle screws in and tightens. Keep the table high to help hold the upper casting when you put that on.

It's not clear to me in the segments of your post I've read whether you're aware of it, but the unit you made this from is part of a multi-tool that was a table saw, drill press, and jointer combination. The press dangled alongside the table saw when not in use, and was swung up into position atop the table saw where I believe the shaft stand was captured, maybe by a thumbscrew arrangement, I can't clearly recall. The long drive belt looped over the two pulleys which were mounted (where you've placed the new motor, and then down to the pulley on the motor which drove all three tools) I have the same unit which I dismounted and rescued from my Dad's old combination tool (which I believe was a Craftsman). That's the reason for the "funky" base. I haven't mounted a motor on mine yet, you did a good job - where did you find the three-tier drive pulley you mounted on the motor? You probably have a different speed range with that mounted, I believe the drive-side of the original arrangement was a single (two inch?) pulley. I think the part you (and I) bolted to the bench top was originally bolted to the side of the saw table with the bolts in the plane of the top so that the saw top was flat/clear when the press was dropped down when not in use.

The man I bought it from did say it was originally attached to a table saw and used the same motor, but I did not see the saw and I have not come across any pictures of the combined unit.

The replacement pulley for the motor is a 4 step pulley I got at a surplus store in Oxnard (great place). Ace Hardware listed one on their website, but none of the stores had one in stock. The speeds may be slightly different than original, but should not be too far off. If I had tried to use a single 2" pulley I would have had to make a motor bracket that raised up and down to get the belt alignment correct.

Sorry I don't have any photos of Dad's assembled Rockwell. You're probably aware the pulley configuration you used is the industry norm for dedicated drill presses, and it likely provides a wider range of speeds than the original setup which required the lengthy (and perhaps hazardous) exposed belt which needed to be threaded through the complex original pulley configuration each time the press was swung up and locked in place to be utilized. I don't remember Dad using it much, but I do remember thinking it worked great when he did. It seems to have a lot of travel (depth capacity) and a good, robust chuck.

Correction, mine has a Rockwell label on it.
