The whole thread has been an attempt to smear Charlie's name IMO
ABSOLUTELY NOT!!! NO ONE WANTS TO ATTEMPT TO CHARLIE'S NAME!
I only do my business!
My facts are:
- defective gas checks
I asked for advice on what to do, and I learned that the way I used freechek was correct.
I know very well that a similar steel can not be worked with a normal saw, and in fact I have used a saw with a "diamond" blade (tungsteno carbide ??? It is a blade with which you can cut the glass).
In the slot of the freecheck there was no aluminum deposit (I had already examined everything with the magnifying glass!): And my blade was able to deepen the slot of an infinitesimal measure, but enough! I lost some time, but I managed to reduce the defect!
Now the gas checks do not come out perfect, but with a small flaw that is compatible with the price I paid!
I AM SATISFIED!
For me the post is CLOSED, and I thank all those who answered me without controversy, and they tried to help me without ... "pour gasoline on the fire!"
