Hi Adrian

What about hard rubber balls ? Glass would work but not forgiving ?
Search in the USA for the brass balls - you might get lucky

Cheers Justin

Hi Adrian,

Stainless might be an option. I have used it on a smaller scale. I find it works well with brass seats. Use on as a sacrificial ball and give it a tap into the seat to set the seat so the new stainless balls should seat nice. Good luck with trying out the glass ones.
Regards, Nathan

brass monkey
Every sailing ship had to have cannon for protection. Cannon of the times required round iron cannonballs. The master wanted to store the cannonballs such that they could be of instant use when needed, yet not roll around the gun deck. The solution was to stack them up in a square-based pyramid next to the cannon. The top level of the stack had one ball, the next level down had four, the next had nine, the next had sixteen, and so on. Four levels would provide a stack of 30 cannonballs. The only real problem was how to keep the bottom level from sliding out from under the weight of the higher levels. To do this, they devised a small brass plate ("brass monkey") with one rounded indentation for each cannonball in the bottom layer. Brass was used because the cannonballs wouldn't rust to the "brass monkey", but would rust to an iron one.

When temperature falls, brass contracts in size faster than iron. As it got cold on the gun decks, the indentations in the brass monkey would get smaller than the iron cannonballs they were holding. If the temperature got cold enough, the bottom layer would pop out of the indentations spilling the entire pyramid over the deck. Thus it was, quite literally, cold enough to freeze the balls off a brass monkey.

That old brass monkey story would be pure fiction. Probably some people think it is true!

Hello Eric.
Which old brass monkey story? The cannon balls or monkey balls?

Anyways, I've used stainless balls in pumps, and for the amount of time they're used for a lot of us (ie a few hours a year), the stainless ones cause no significant wear but, as Justin says, long term use would flog the brass out. I did flog some hard plastic balls out of the cats toy once. I got into trouble over that one, but they worked well.
Never thought of using marbles. Why not?
How would making Teflon or nylon or similar inserts for the valve seats work so the brass valves aren't flogged out with stainless balls?

Cheers Scott

Glass may be too light to seat when needed. Also, the constant pounding of the glass against the seat may end up fracturing the glass into fragments. As others noted - hard rubber might be a better solution, or check out other vendors like McMaster Carr for your needs. for the short term use, a stainless steel ball should work fine. It probably would weigh the nearly the same as the brass one it replaces, so pounding should not really be an issue
