Use some silicone spray for assembly, lightly spray around the pocket where
the blade will insert.Roll the rubber pocket rails back to allow the blade
to insert. I get it started, then put the heel against my chest, and pull
hard to get it all the way into the pocket.
Next, roll the rails up onto the blade edging, engaging them with the rubber
rails on the blades.
I don't remember if you have to trim the picasso pocket ends or not, if
there is an engagment notch in the picasso blades, you'll have to either
trim off the last 1/2 inch of the pocket rail, or carve out the piece of
rubber that engauges with the blade. You'll see when you go to finish the
rail onto the blade.
OK, now the blades are inserted, rails are on, hold them up and sight them
from the heel to see if theyr'e straight in the pocket.. If they look
straight, they are. If not, just tap them to get them straight. Now, both
are done, stand them on end, tips down, to see if theyre approx the same
length. If they are, your good to drill. If not, strip off the rails on the
longer one, and start over, pulling it into the pocket again.
Then drill whatever size hole you need to allow the screw, and tighten down.
When you drill, back up the blade with a piece of wood, I land them on a
2x4.
