Jim, you might try what I have done to several drill presses in the past that didn't have cranks to lift the table, and they worked great, (even on some large DP's with REALLY heavy tables.
Make a clamping strap from a 1" wide strip of 1/8" thick steel that will go around the column and place it around the column at the top just below the powerhead. (You MIGHT even find one that would work in the Fence section of the Big Box stores, that are used to fasten chain link Gates to their gate posts). Mount it so the bolt will be at the back of the column of the drill press and fasten a pully to the bolt that pulls the clamp togetherNext, get a small cable (or even a rope) and connect one end with a hook that will connect to the table's clamping bolt that is at the back of the column , (or sometimes you can just hook the "Hook" under the back edge of the table), whichever works best, and then run it through the pully and attach some weights to the other end of it. The weights should be close to the same weight (or slightly heavier) than weight of the the drill press table. We used to use old window weights, but you probably can't find many of them now but you probably could find some weight lifters weights (that someone's mom has discarded OR wants to get rid of).
The cable/rope length should be adjusted so that the weights just touch the floor when the table is all the way up to the highest setting you will use. The more compact (shorter height of the weights) the more table travel you will be able to get without the weights either touching the floor or the pully on the other end of travel. With this installation, it takes very little effort to raise or lower the table.
Note: If you want to get the maximum "Travel" of the DP's table without the weights either hitting the floor or the pully, you will have to mount two pullys at the top of the column and one pully connected to the weights to keep the weights from running into the top pully or hitting the floor. Note: (if you use the two pullys at the top method, you will have to add more weights though)
Heck, if you put one of these on it, you may not even want to get a new drill press, and you MIGHT even get some help from Glenn, (if he thinks he might inherit it someday).
I don't know if you could find an after market keyless chuck that would fit your drill press or not, but that MIGHT be an option as well.
Hope this helps and Good Luck.
