I wanna make a power lam but have no power tools  for doing a taper. I have a make shift disc sander and have done some really good work on that.  Any other ideas.?

Sam has a power lam build on his site using a belt sander. I have also done some using that method.

You could take some 40 grit sand paper, tape it to a table of something, and rub the end of your piece of wood against it until you get a taper.  Or you could use a block plane, although that's difficult.

You ought to be able to use your disk sander, though.

That is a heck of an idea you gave me.      
I'll rough it out on the sander and do a finish taper on the board.  I made up a board ages ago for doing lids on boxes that did not fit flush.  I have a couple planes but I have to skew them to cut, never get a true flat surface.

Ok so I'm almost done,  having a hard time getting the transition perfect sandwiching it between the lams.  I'm getting about .008" small gap just where the taper starts its about 1/2" long but does not appear to go the full depth (during a dry fit)

I build glass bows and use a thin p.lam. it Sounds like you need to lengthen the taper.. A block sander may be the best tool now since you are at the dry run stage..
