Jim I was there and the 1.8 tool was used and compliant when the pilot was in the guide correctly. At that point they realized they haven't done a 1.6 for 5 years and they don't have the wright tools.
As Chris said, there are no 1.6 tools. The pilots are the same(1.6 and 1.8), the tool heads are not. No 1.6 head could be deemed compliant( or non compliant) with any 1.8 tools as they are not remotely the right tools and way too big for the 1.6 head. There is just zero relevance. Not sure why tech staff would even insert the pilots as they are well aware that they don't have those tools? But I don't doubt what you said above, maybe they just continued on with their normal procedure until the realized that they didn't have the tool heads for the 1.6? I have no idea.
Even if the head were a 99, the compliance tools would not be the decision maker on the short turn radius. They have a feeler gauge like tool with 1mm notch, one with 1.5 mm notch and one with 2 mm notch. They lay these tools over the deburr area. If they see any marks / scratches are outside 1.5 mm or the area or if the area is manipulated, they will DQ the head. I have not seen the head, no idea what was or wasn't done. I have no opinion on this head, I have not seen it, just clarifying what I know of the process and the tools for those who have not have the pleasure of this exam
After 14 deal at Runoffs, I had one head DQ for STR in 1/15, we believed it to be compliant.
There were literally a few file scratches over 1.5 mm on three holes, there was no tolerance given. Not sure what they saw here on your head, but I know from experience, they give no tolerance and the decision is not something you can appeal.
Is anyone here aware of a 1.6 head being looked at in tech for compliance items(podium car)since the STR rule was put into the GCR in 2015?
Yes, they have a 2014 compliant machined 1.6 head in Topeka.
.making the need to "de-burr" a sharp edge a moot point(this is MY observation).
This is simply not accurate
