Indeed.  I'm making a gasket instead.  

However, I may yet be able to provide a surface for the 
o-ring.  The present cutout is undersized.  At the time, 
I only had a 3/4" end mill for cutting it, but it's 
supposed to be 2.0cm.  I put in an order for the correct 
size cutter with Rutland.  If I'm very careful, I think I 
can leave a 2mm seating surface all the way around.  If 
not, the gasket will work every bit as well.

Yes, and after I get the bugs worked out of the production 
process, there'll be a third source.  

As I mentioned in an earlier message, I'm almost done with 
one that offers two threaded bosses for sensors or remote 
feeds.  If someone wants one with three bosses, I can do 
that, too.  I have to be out-of-town next week, but I 
should have more stuff to display after Christmas.
