N54 Cam Ledge Alignment

Is there any way around buying the tool for $500 to align the upper and lower cam ledges?
I can get the cams compressed but I can't seem to do the ledges because of how accurate they must be.
I already have the timing kit so that's not a problem.

This is where I would be buying the part from, and it doesn't even have the n54 compatible ledge alignments:

If anyone has this tool and can rent it out to me I would really appreciate it. Just want to finish this build already so I can start braking it in for a ST.

Below are pics of what tool I'm talking about and what I'm trying to do:

It doesnt do anything but put it the top and bottom half in perfect alignment. The c clamp isnt a pretty or "proper" way to do it but why wouldnt it work?

How stupid!!! The two halves have been machined inside to a perfect circle so that adequate oil clearance for a camshaft long life exists. When you assemble the two halves with this tool you maintain this clearance. When you don't use the toll the alignment of the two halves is gone, the perfect circle now has two ridges at 180 deg from each other that are eating into the clearance and are now wiping the oil of the surface of the camshaft bearing ... a short life for the engine is now assured...

Dude... BWM factory's are not there to make things pretty but to make them "proper" so that your engine lasts a long long time! I do agree that BMW engineering screwed up the N54 with its steel rectarings eating in the aluminium bearing surfaces yet by not using the half-bearing alignment toll during installation of a new bearing is just taking stupidity to another level!
