Whenever you are casting with a Monotype machine, it happens nw and than, that from under the nozzle, a splash of lead escapes.
This can built up quite a large piece of lead, under the mould of the machine. It even could built up inside the machine interior, in such a way, that the mechanism to control the pump-mechanism would not function at all.
Recently I decided to try to stop this with a spat screen around the base of the nozzle.
This was made from the bottom of a metal beer can. This was but from the bottom, with a hammer this was made spherical, and a square hole was made in it. The hole is just enough, and it takes a little force to put the screen on the base of the nozzle.

Only 5 mm of the wall of the beer can is left, and this will avoid the lead splashes. Because of the high temperatures at this place no lead will built up, and all will go into the pot.
There is plenty of room for this when the nozzle is positioned under the mould. It worked fine.
One thing to remember, just use a iron beer can, do never use aluminium.... keep that metal for from our lead.
