Um, WOW! Crystal door knobs are so cool. Love the fact that the garage matches the house. Great idea of the leg on the gate post. Another example of bigger isn't always better. Big kudos!
Another tip, if you're not familiar with what settings to use for a particular metal thickness, use some scrap of same size to get the settings right before starting on the project.
I believe they're for the smaller diameter dies sets. My 1" follower uses a lower number than the 1-1/2" follower, so it makes sense that the followers down to 1/2" would even lower number holes.
My understanding is the model 32 is a heavy duty version of the JD2. I too added a HF air over hydraulic ram, and love it. The Swag unwelded bracket for the ram is $100, so I built mine from tube and 2 main caps I had. I highly recommend the ram.
Well, I knew you made your own mandrels which is crazy good. But going thru your flicker pics I see you made your own tubing bender, of course! Talent overload me thinks. Kudos to all you do, and at a top shelf level! Fab p0rn at its best.
