The center line is a huge help. I also suggest that you draw a center line down one side of the strongback (to help with the vertical alignment. I used an electric nail gun to help tack the forms in place until I got the screws in. I also found it helpful to have a variety of small wedges to help move the forms into place. Keep at it, you will get it eventually. DON'T DO THIS WHEN YOU ARE TIRED, I found that it is much easier to do it in the morning when my brain is working.

Good Luck,

: Guys,

: I have a nice set of blocks already on the strongback, which is internal.
: Clamping the forms to the blocks while drilling/screwing i can handle.
: The forms are spaced by 30,1cm's, as that turned out to be the measure
: fitting into my strongback overall length.

: Will try the "coffee-cup stirrer" method, plus removing all forms
: and create a center line down the form with a string.

: Additionally a lot of patience will probably get me there :-)

: Thanks,
