What I am looking for are sugestions regarding methods of
construction that will result in a true running shaft.

How does it look like? Does it have disks or just arms on the side?
It is a good procedure to make both sides as one part and the split them
(part off, splitting saw). If you machine it from cold drawn steel, stress
relief it before machining.


For example how
best to clamp the parts while the tapered pin holes are drilled and
reamed ie Loctite first then pin or Loctite after all driling and
reaming.

Do you have a drawing? Split con-rod?
There are some tricks how to get it true running with the right setup while
machining. But it depends on how the crank looks like.


The shaft will be .625" how much clearance and what type of
Loctite? Any and all sugestions are welcome.

It doesn't help that much to Loctite and have a press-fit. A perfect
chemical press-fit (AKA Loctite) needs a gap of 0.05 .. 0.1mm (read the
specs!).

It's best to learn to make real press fits. :-)
