Scotch Yoke Modification
(OP)
Can anyone suggest a modification to the Scotch Yoke Mechanism which will produce a uniform rate of motion of the reciprocating slider as the crank rotates. A standard Scotch Yoke does not produce a uniform movement.

You should probably check out the theory of 4 bar links, and consider extending it to 8 links, depending on what you really want.
There are numerous downloads of mechanism or linkage simulators available, perhaps the most versatile of the freebies is freecad,
available from http://www.askoh.com/freecad/ . It has a steep learning curve, there are much simpler programs available.
