 Jeff this step file should import into solid works OK.
 If you have trouble doing this let me know.
 I did not fillet the bottom of the pockets as Rhino does
 not do that well. Just use a 1/2 inch ball mill for the pockets.

 I think the best approach to the spacers is use 1 inch
 round aluminum bar stock and tie them together with
 tig welded 3/16 sheet. Two are counter bored for
 the hollow dowel pins. For a fine touch the sheet can
 be rolled on a 14 inch radius. This, I think, would be the
 lowest cost way. Putting the motor mounts on the plate
 relieves the spacers from the 600 ft pound prop torque.
 The only thing the spacers see is the 200 ft pound engine torque.

 The counter bore on the back side is a per Tray's instruction
 to hold his shaft seal.

 Be a good idea to make one set and see if it fits a
 end housing. If you don't have one I can have Mazdatrix
 ship you a junk end housing.

 The Barry cup holder stp file will follow shortly.

   type.....

 OK Jeff Here is an iges file zipped.
 What version of SW are you running Jeff?
 Jarrett would you please try to load that stp file in SW.

 Paul Lamar
 There ya go..

  Jarrett

  Thanks Jarrett.
  Try this Jeff.

  How does the SW rendering look Jarrett?
  Was everything OK?

  Paul Lamar

 Yup, I tweaked the 'visual' stuff so it was easier to see [changed
 the color] and checked it for surface errors fixed a couple and
 then made sure it had resolved it as a solid body before sending
 it back [sounds more in-depth than it really was :) ]

 Jarrett

 Thanks Jarrett.

 Here is the Barry cup holder. To be tig welded on the
 ends of the motor plate. I simplified it some what to cut cost.

 Both stp and zipped iges.

 Jeff, we will need two of these for every motor plate 2.5 inch OD
 6061 T6 bar stock is fine as is for a finish. It is the thick
 mounting for the Barry rubber bushings.

 Jarrett please check these as well.

I got the iges but not the stp.      Cup holder looks good...

My version is, lets say, earlier......pre-2006.   If  Paul can send you
good files to SW the send back to me in X-T ver 13.    If I can get the
plate geom this could be cut  and delivered before the weekend..........
C. Smith is sending me the Tracy plate to get the register tolerance right.

jeff

Good work Craig. BTW take a picture Jeff. The early Tracy plate dwgs had a
starter bolt mounting position error.

I fixed it in the new design I just sent.

Did you get the Solid Works files OK Jeff?
