This is made from .090" thick 4130 sheet and 1.5 by 3/4 by 3/4 inch
long 4130 rectangular tubing tig welded together. The sheet is water jet or
laser cut for accuracy and ease of welding in the short sections of rectangular
tubing.

Flex plate is 3.4 pounds with ring gear.

Sheet metal driven is 2.4 pounds.

Molded low durometer silicone rubber blocks fill the spaces between
tubing sections.

The Ford flange with the drive spline weighs about
3 pounds. Some of that can be machined away as unneeded.

The advantage of this approach is everything can be changed
or adjusted if necessary.

It can be sold as a kit of parts for those that can weld.

It might be possible to use it as a mold for liquid silicone
rubber.

---------------------------------------------------
There is plenty of precedence for this design as it is more or less
a motorcycle rear hub copy. The diameter of the damper part can be cut down
by machining down the diameter of the Ford part. In fact the
first one I build will be done that way.

dwgs on that soon.
