My comment was simply related to Material Science ... Heat & Vibration Fatigue Cast AL. ... Especially Poor Cast as in today's production stuff ... People want to make their Profit and tend to cut corners ... Good Cast AL Stoc isn't Cheep ... Most bowl/pump manufactures 'Out Source' their castings and have not the slightest idea of what is being produced for them ... But, they sell it under Their Name ... Check it out for yourselves and Do what your going to Choose to do.
Not 'Bad Mouthing' what your doing Brian ... Just commenting ... Maybe To Much Winter & Not Enough 1/4 Milen'.
