Hi, fellow rotary enthusiasts....We finally finished research and
development on the 90 degree oil filter adapter for the 13b.  The

I
had with the original oil filter location was that the height of the

filter would interfere with the top of my cowling. I purchased a

oil
filter adapter kit, and after looking at it, I decided I did not want

extra weight, extra hoses (every additional hose is a potential leak),

it just didn't look very professional. A machinist friend of mine has

oil filter adapters for Lycomings, so we put pooled our ideas and came

with this 90 degree adapter. It lowers the overall height of the oil
filter,
requires no additional hoses, and best of all, it uses the original

filter "pad" that comes on the engine in the first place. Why

the
part that the oil filter screws onto if it ain't broke?  Plus, I can

still use the original small oil filter. He is going to make a few of
them,
and I guess we'll see how much interest there is in them. Here come

pictures.  Thanks in advance for any and all comments and suggestions.
     I have more pictures from different angles if anyone would like.
