balancing a fork mount?

hi,
would you'll have any tips on balancing a fork mount?
I've built a fork mount for an F6 Newt, which I guess is unconventional, but then it was easier to build than a GEM and I can't get an EQ6.

I read that for forks, you first point the scope at zenith so it is not top heavy or bottom heavy, then point it horizontally and balance it.

these two steps are fine in my setup, but issue is when the scope is not parallel to the RA axis, and the fork arms are around 45 deg from the ground. it tends to swing back to parallel to ground. does this mean I'll need another set of counterweights for this angle on either side of the scope to acheive proper dynamic balance?
I'm just trying to balance it with an slr at the focusser and no other equipment. have got weights near the secondary on the other side of the focusserl
