This is a modified HF 1/2 ton. If HF isn't selling the 1/2 ton now, there are lots of other sources on line.
The square vertical shaft can easily be drilled for a StewMac caul assembly and is held in place with a small knob that goes thru a tapped hole. The knob is used instead of a setscrew so I can easily swap the caul for a guillotine miter cutter. The return spring is a useful feature and easily installed. I replaced the main handle with a torque wrench, which helps get all the frets in at the same height. Today I set up a new tenor ukulele with Evo frets on a radiused ebony board. It was uncanny - all frets were even at the center and both ends of every three-fret group. Absolutely no fret leveling required. This doesn't happen every time but the arbor press definitely eases setup.
I used a drill press in the past. I find that this rig is easier to use and yields better results. Even though my drill press is a pretty sturdy unit, to keep the table from being deflected by the downward force of the cauI, I had to use a temporary strut under the table.
