|Something tells me that you're in way, way over your head.
But, given the fact that it's a big lens it's much easier than if it was a CZJ 135/3.5.
Zebra version to be more specific.
Now, you need a wooden dowel inside the barrel with the same diameter as the barrel itself and then you can start laying down the blades.
The tricky part is that every blade but the first one, obviously, should be positioned UNDER ( not above ) the one before it. The second one goes under the first one , the 3rd under the 2nd, so on and so forth.
If you don't do that it will not open correctly.
As usual it might be other methods to skin the proverbial cat but this is the way I did it.
