Assemble in this order (front to back);

Nut, washer, rubber sealing face, wood disk, washer, nut, (length of rod), nut, washer, rubber disk, wood disk, washer, nut.

The front is the sealing or barrel side. The washer should fit inside your barrel.

I'll leave off the nuts. The washers are in red.

I think it was clide who said that unless your piston is really heavy, weight doesn't effect opening time too much.

I've said that a few times as well.

I could effectively halve the mass of the pistons I currently use and see no discernible performance improvement. I'd struggle to spot the difference if I had a chrony to be frank. However my pistons aren't exactly hugely heavy in the first place.

Doesn't mean that heavy pistons should be ignored though. It's still a good idea to keep the weight down as much as possible.

Piston weight may not affect opening time... but a heavier piston has more momentum... so keeping weight to a minimum is generally a good idea to reduce the chance of damage to a cannon, especially PVC ones.
