Thanks Mike, that is a good data point. But since my measured number at TDC is 0.001" off, I guess I'll have to turn myself in to the Machining Accuracy Police in the morning. Or should it be the Measurement Precision Police?
Mike- Did you indicate the valve stems in the collet to make sure they were running true? That would be my big worry making two piece valves. Parts don’t always run true in collets. -Bob
Hi MikeSorry about the problems, but at least it feels better knowing that you have solved them As I'm sure there are several who would like to see and probably use the revised drawing you did of the head - I wonder if it would be OK to upload it to the drawing section ...?Best wishes Per
Hi Mike. The test fixture I made the other day is almost the same as yours, differing only in minor dimensions. When I get the chance I will follow your lead and do the dunk test. The only unnecessary hole in my head (cylinder head, that is) is the one for the rocker post. The post does have a shoulder, which will help a bit, and I'll goop it up well. I'll be following your build even more while I can't work on my own!
