Hello,
So my top is almost finished. I am just fairing a little more and getting ready for the paint.
I am planning on having 2 scissors mechanism on each side to lift the roof about 30-35" high. the top is about 100 lbs right now. If I mount a rack or bikes or kayaks, it will be much heavier, so much harder to raise. I would like to mount some springs in between the scissors to help bring the roof up (and keep it up!!). 4 springs in total. Let's say to help raise 100 lbs of roof + 150 lbs of "stuff". So 250 lbs divided by 4 springs is about 60 lbs per spring. Very reasonable. BUT!!!! If I have 250 lbs of springs load to help me raise the roof....what if I want to lower the roof and there is no "stuff" on top???? Only the 100 lbs roof...Do I have to pull 150 lbs down??? That's almost my weight..do I have to suspend myself to lower it? a bit of workout every morning before I change campsite!!
do you think it works like this or springs have their own special magic?
thanks
JT
PS : the system would be very similar to an older VW roof I think. I have seen a picture on Spurious van with that mechanism...
