[modeleng] Re: The ban on paint stripper and clack valves

Tel,

No es necessario to make volcano.  Just use an end mill to get a perfectly 
flat surface sans chatter marks and the resulting sharp edge will seat 
perfectly with a stainless ball.  Main thing is to not have any chatter 
marks or you may never get the seat to hold.
