"Well, mine's a 1938 Cincinnati" - I love vintage tools but that just wasn't coming together for me. Now that I own and have used a full size DP, I'm in a better position to restore an old one. But that's yet another hobby!!!
"adding simple accessories it will be able to do much more": Already fashioned a DIY drum sander from scrap dowel and a bolt. Has some runout but works well enough for the tasks at hand. Am leery of a fence: too much set-up time. Instead I'm using the "shift & drift" method (my homespun terminology): Mark ea. hole with an awl or center punch. The drill bit will want to follow, and self-center that hole, by pulling the workpiece into alignment. A "stop" on the DP table keeps the workpiece (or vice) from spinning. The laser crosshairs are good enough for this process, to locate the dimpled hole under the drill bit.
The problem with a fence is constant, repeatable alignment with true center. This will change eveyy time the table is adjusted! Also, if you're drilling an amp chassis, you shouldn't believe that it's truly square. There's no straight lines in the real world.

If the fence or the chassis is a hair off, the discrepancy will magnify as you slide the workpiece along the fence.
As I have no one to teach me, I learned a lot on google, especially here:
