Most of us use arbor presses with eyelet dies as well. Normally it's just a matter of drilling a 3/8" hole (give or take) into the anvil and the end of the ram, and inserting a set of eyelet pressing dies. I think boss dog even sells them pre-drilled in his store, but it's a pretty basic operation. Looks like you have it working nicely!
I need to learn how to make kydex sheaths. Good job.
I usemy drill press. I got a set of dies from Knifekits. I drilled a hole in a piece of steel to hold lower die and Chuck top die up. Just lower the Chuck is enough to do the rivet.
I had posted earlier asking how to modify the press but no-one posted so i went to You-Tube and watched some videos. It was straight forward like you mentioned. I did add a magnet in the presses lower plate to retain the lower die, and make it easy to remove. Worked very good. I'm debating on grinding the 2 teeth on the Ram off to get that ratcheting effect as the Ram is in the ideal spot at this time?
I haven't seen anybody grind their arbor press teeth, though that's an interesting idea. For my press, given its size and stroke length, plus the distance of the dies, I don't really see any advantage, as I don't typically have to pull my handle more than 180 degrees (probably much less) in order to get a press each time.
