Sprite Motor Mount, Part 1

After we slid the motor and transmission in, we had to figure out the bolt sizes of the four transmission cross brace.  It is a job that would have been much easier before we put the motor into the car.  But the internet is a wonderful resource and we were able to narrow it down to 1/4 inch, 5/16ths and 3/8 imperial fine thread.  Here you can see the shifter port coming through the tunnel, and the shiny bit on the vertical wall of the tunnel is a 5/16" x 1" fine thread bolt.

 Two more 3/8" x 3.5" fine thread bolts are installed from under the car, just behind this stack of wood.  The wood is holding the motor in the correct position so that we can take measurements and determine how to fabricate a front motor mount.

 The space is tight, so this is the best shot I could get of the motor face.  There are 3 M10x1.5 mm  tapped holes that can be used to mount the Remy HVH250.

 We start out with two lengths of 1.5" x 1/8" flat bar (38 mm x 3 mm).   Using the motor face as a jig, we grind the parts until all three holes are aligned to the motor face...

...and then weld the parts together. 

Flat bar will not be substantial enough on its own, so the structure is built up with some square tube.

 All the seams are welded.

 Here the mount is shown in position.   We will need to get some shorter bolts.

Up next for the motor mount is to extend square tubing out to the mounting points of the car, and connect to the rubber mounts.
