Well, there are a couple ways. The easiest is to buy a brass & 3D printed cylinder like an. It's a direct replacement that's easy as pie. You'll be up and running in 10 minutes.

Alternatively, you can buy/print a 3D replacement cylinder that is designed to hold 17/32" brass tubes like one on Thingverse from Eightbitbuenos. It's just a matter of cutting and fitting the barrels, then reassembling. It's probably an hour's work.

And finally, there's the hard way. You can manually widen each of the chambers in the stock cylinder and retrofit brass like  did. I can confirm that 17/32" won't even begin to slide into the exit end of the barrel. You'll have to use a 1/2" bit and carefully drill out each of the chambers. If you have access to a drill press I suggest you cobble together a simple jig to keep the cylinder housing parallel to the bit. It's going to have a tendency to wander, and there's very little margin for error because the walls of the stock cylinder are already pretty thin. Unfortunately, after all that work you'll only have a 5 shot Hammershot when you're done. So go slow and godspeed 🤞
