And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.
"ExtrudeHone" was the patented process. worked well for polishing things. It turned out that in some applications the surface roughness was a good thing. However, when all one is doing is moving very low viscosity fluid(air) thru a tube(intake manifold) smooth is good. moving air with fuel entrained in the air, surface roughness helped keep the fuel entrained with the air. process was sort of pricey as I recall and could remove a lot of material very quickly, like a semiliquid grinding wheel
More trouble than it's worth. I build 25+ engine's a year & I don't see any use for my shop. But then I build hp outboard engines. A little ball hone & a flapper wheel does the job.
Not really cleaning, more of a polishing and removing sharp edges.
ReplyDeleteIt's a form of old fashioned valve-grinding compound firmed up.

Was suppose to equalize the flow pretty good between runners, too!

ReplyDeleteHuh. That's what what the coronavirus did to my bowels! They've never been so clean.
