I tried making a dished washer out of 12L14 round stock.  It applied pressure to the slotted disk only on the grooves.  It stop the leak on one side but introduced a leak on the other side.  I have no idea why.

So, next I decided to install an o-ring between the valve members.  It would have worked, except the o-ring slot depth cut into the port connecting holes drilled in the back part... sigh. 

So, tomorrow I will remake the reversing valve body and drill the connecting holes further back in the part so the o-ring groove won't cut into them.  There will actually be 2 o-rings, one outside the slots and one inside the slots.   I think this is going to work.

Edit:  I forgot to mention, I may have a problem with air leaking from slot to slot.  The o-rings will have to compress flat enough that the metal parts still come in tight contact.

Though not sure if you have looked up the meaning of a 'step' in a process. Maybe you should have been a software engineer.   :LittleDevil:

Ouch.
