Sorry, it had been drinking, I'll have words with it.
Yes, so that the head is against the top (unfaced face).The coin/penny is drill thru and the bolt goes thru it?
Yes, like a dolmen.this then rests on the pin heads for contact?
YesThe spring pushes down on the penny/bolt for adjustment?
Yes. To be honest, I haven't put any on the prototype, but I thought it would be a good idea as if the probe gets pushed sideways the diskAnd the silicone is for keeping the penny from sliding around?
can rub against the inside of the cylinder and hang.
I would put it outside. That way you can put it on afterwards when you're happy it's working. Or you could use a small piece of silicon tube maybe.And from what I gather the silicone goes around the prob inside of the shaft hole underneath the pins???
