[PSUBS-MAILIST] hemi heads

[hank pronk via Personal_Submersibles]

Sean,There is a problem with EE  after I paid and was sent the work order I noticed they measure the head height from the inside when in fact the apex is the thinnest.  That makes the sphere elliptical.  I contacted them and it turns out the template tolerance they said they could meet is measure on the inside.  So I am modifying the order so that the heads are measured from the outside, this way they are 1\2 as tall as wide.  I will true them up from there.
Why are you contacting them?  are you starting a project?  Do tellHank

Sean,I did just as you recommended,  I have been talking with EE and they say now they can produce the heads within my tolerance.  I told them 1\2 of one percent of dia  measured with a 120 degree template.  They say they will  measure the heads with a template before they ship them.   They have been extremely friendly and accommodating .  I even told them what it was for.Thanks' for your inputHank
