[SEL] Foundry Question

[peter ogborne]

Thanks for your interest Jim.......Danny the ''Foundryman '' is visiting me 
today ,I will arrage to get a photo of the set up.
Danny has been very succesful in casting vintage and veteran motor cycle 
parts ,aluminium chain case's and the like ,bronze bells and other parts 
.Cast Iron has been limited but has been successful. But now this noise 
problem has come up .As Danny lives in close proximity to his neighbors we 
must solve it otherewise he may have to cease. Any advise or help would be 
verymuch appreciated.
