It was a lousy day for chrony testing, cloudy, windy, the odd shower. Very frustrating, but managed to get some results. The 9.6 gram darts performed quite well. 435 fps (132m/s) with 87.5 joules of energy at max pressure. Absolutely lethal ammo without a doubt. Only downside is single use. Even shooting into a cardboard box filled with rags the nozzle tails badly deformed upon impact. Conditions were problematic shooting 15mm steel. Only got one good reading, shooting 279 fps (85m/s) with 50 joules. This was a disappointing result, expected more energy from 14gram projectiles. Could be a windage issue with the patching or the rig is optimized for lighter ammo. More testing is needed to confirm either way.

Finally tested 15mm steel and 16mm marbles. Used patches and muzzle loading to start with. Could not get any sensible readings at all. The only explanation I could see was the balls and patches were separating over the chrony. Had some spare cones left over so I simply hot glued them to the balls. Problem solved. Performance was excellent, these sabot/skirted hybrid projectiles really work well.
The marbles easily exceeded 500 fps and over 100 joules.
The 15mm steel nearly gave 120 joules of energy at 400 fps.

No tutorial needed. A bit of gluing some pvc pipe and fittings. A little research online and viewing a few youtube videos will give you all the information needed.
It's a lot more fun building something original with your own ideas than simply replicating what's already been done.
Have fun, but be aware even low pressure air has the potential to injure or kill.
