Given how often these assorted pot metal trunnions fail, it seems to me that there may be an opportunity for someone with either a CNC or a 3d printer to make some that are more durable.
It came to pass...
"Curiosity is the ultimate power tool." - Roy Underhill
The road IS the destination.
Of all the laws Brandolini's may be the most universally true.
Deep thought for the day:
Your bandsaw weighs more when you leave the spring compressed instead of relieving the tension.
It's absolutely true, but metal printed parts require $1M+ printers, so they are (at least to my knowledge) only used for pretty high value parts. I know of some people in the startup world trying to bring that down by a factor of 10 or so, but you're still not talking inexpensive. In our engineering lab at work, we still outsource metal printing, even though our machine shop has many plastic / resin based 3D printers, and an otherwise full-service metal machine shop. You can literally go online with your CAD files, get quote and order one-off or short run parts in a variety of sintered alloys roughly as easily as you might order a custom printed T-shirt.
Because these same trunnions were used on Delta band saws, check with Louis Ittura. He may have a list of compatables. Google is your friend. Google "Jet trunnions on a Delta Band saw," and the answer is there. Yes they do fit. Ebay has a pair of Delta for $30 delivered right now.

New US-made drill presses with an appropriate spindle travel and spindle speed for woodworking are not common. I know of two. The Ellis 9400 is an 18" unit with a top speed of 1200 rpm, spindle travel of 5 3/8", and costs about $4k. The 20" Clausing can be run up to 2000 rpm spindle speed with an 1800 rpm motor, has six inches of spindle travel, and costs about $5k. I have a 50 year old version of the current Clausing 20" and it makes a VERY nice drill press for woodworking as long as you get one with the higher speed motor. Mine survived getting beaten on in a metal shop for 50 years so it is a pretty stout unit.
If I had to buy a new drill press today (I wouldn't, I would get another used one), I would get something like the Grizzly G0779. It's a Rong Fu RF40 gearhead mill head on a drill press column with about 23" of swing, 5 inches and change of spindle travel, and has a speed range of just under 100 rpm to just under 2000 rpm. It goes for a little under $2k and is of pretty heavy construction. I would not want anything to do with the lightweight presses like the Delta or the typical consumer level units.
