Question on feeler gauges
It's spring and among other things I'm doing, going to check and adjust the valves on some of the engines. Couldn't find the feeler gauge I usually use, but discovered another one which I'd forgotten I had. I'm used to gauges that have ".oo4" etc. on each feeler. This one just starts with "1" and continues and is about an inch thick with all the gauges it contains. The fellow who gave it to me was a retired machinist and I'm wondering if the "1" is actually ".001?"
The gauge I usually use had been borrowed by my brother one day while I was at work and he'd forgotten to return it. He's currently in bed with pneumonia, so it'll be awhile until he wanders down to his barn to disinter it.
Anyone familiar with gauges that use this marking system?
