Hi tph1
No there is really no need for such a fancy tool. A simple bathroom scale is quite adequate if you want to calibrate the press, it isn't that critical, then you just have to remember how many turns you did.
You can also, before gluing put the cores in the press and start pressing down on it at the root and count the turns, notice when it starts to crush, then go no further. Do the same with the wingtip. Then you will notice you can probable only do half as many turns before crushing the tip. Then you will have to even out the pressure on the other clamps.
The trick is to gradually and evenly reduce the pressure to the wingtip. It will also help using a straight edge to see if the clamps are all in line.
The Typhoon wing is the only wing that was a little bit tricky because how much the wing tapers towards the tip. All other wings I have done, I have just calibrated the press for even pressure and that has worked just fine.
I use this press because I got so bored stacking weight on the cores, besides, when the press is taken apart it doesn't take up much space.

But the best idea for a wing press I have heard came from a friend from my club, who owns a huge air compressor. His idea was to use air jacks to press on the cores. Then you would not need to be stacking weight or tightening clamps, just push a button. How expensive the jacks would have been, well that's another story
But it sure sounded good.
