   Thanks for the input.   I don't understand the change you are
   recommending.  I am sure that is my problem and not how you
   expressed it.  But can you take another shot at describing the
   modification--just pretend you are talking to a complete idiot.   We
   can get Paul involved so that the plans are modified.          Jerry

    Jerry, thanks for the suggestion on the bushings, I was
    considering how I would approach that.

    Feel free to use me as a reference.

    Assuming you take on more 801 mounts, you should consider how to
    provide the necessary clearance to the nose gear shelf. At a
    minimum, provide some 0.5" spacers. Those of us w/o machine shops
    don't have the odds & ends of materials to utilize. The best
    solution is probably to move the point where the frame member
    welds to the mounting bolt 'tube' forward that amount. I ended up
    spending an hour on a hack-saw cutting up scrap 1/8" plate to get
    my spacers.

        Kenny,  I think I forgot to mention this before but after you
        get the strut installed you can make bushings that go on
        either side of the rod end out of 1" o.d. x 1/2" i.d. aluminum
        tube available at any metal supplier or from ACS. Leave about
        1/16" clearance.    This will give a nice finished look to the
        installation.

         Also, may I give your name and contact info to a Ch 801
        builder who is considering an engine mount?   Perhaps you
        already know him.  Name is Kenneth Johnson.                    Thanks,  Jerry

   The upper mount arms interfere with the nose gear strut shelf (see
   picture). The angle the arms descend from the mount point must be
   sharper than the lycoming mount. Paul recommended I simply add
   spacers to push the mount forward 'enough', so that's what I've
   done. It would require fewer moving parts to integrate that
   clearance into the mount somehow.
