         Patrick and Kenny,  here are some pics of Patrick's 13B
        engine   mount.
       The renesis is the same except for minor details.  When you
       attach  the mount
       to your firewall,  start with the bottom corners first and it is
        much easier
       to get the bolts in  with the S-beam removed or at least with
       the  two 1/2 inch
       bolts loose.  I taped the firewall bracket in place without any
        measurement
       just to see how it would look.  I think the bracket  will be
        somewhat higher
       on the firewall in final installation.  You can move the strut
       left  or right
       to get a perfect (centered)  line up between the two brackets.
       Then  measure
       what size spacers you will need and I will build them for you.
       Kenny,  your
       engine mount will be in the fixture Sunday.  The S-beam, corner
        bushings
       and fuselage bracket are done.   Jerry

       Looks great Jerry!

       I'm out of town at the moment so I can't take a picture, but before
       I hit the road I noticed something I wanted to ask you / Paul about.

       The nose gear strut channel that the new lower mount brackets attach
       to has a rolled flange along the top edges. The flange rolls
        'outward'.
       Based on the drawings, I think it very likely it will interfere with
       the new brackets.

       Assuming it does, would it be OK to trim the flange upwards so that
       it clears the new bracket? I believe the flange is just there to add
       stiffness to the strut channel, which should be more than
       compensated
       by the new bracket. Just want to verify it with you guys though.

       Not a good idea. How thick is the roll?
       A close up picture would help.

   An aluminum doubler thick enough so that it is flush with the roll
   should take of  it.    Jerry




I'm still out of town, but I found some old photo's that show the flange:

Bolt it to the firewall and the channel with a bunch of 8-32 screws
using the spacer and it will be fine. At least six per bracket.
Eight would be better.
