Process of reflexing while sinewing

Hello again…This is about avoiding twist while drying.If everything is done and measured right it should’nt occur anyway.
This may sound dumb but when reflexing those little power packs your making do you after sinewing clamp the bow to a rail throughout the whole reflexing process?Or just after it gells?
I realize a notch is cut into the belly of the tip,otherwise with the abrupt set back of the tip the revese bracer would come off.
Maybe it’s reverse braced later to let the sinew do it’s thing?
I realize I think that clamping it to a rail might help with any warping or twisting that might occur.Like shown in Adams’ book.
Then after drying a few months with final sizing tieing the tips close together and pressing it down into a pretsel.
I’ve always just reversed brace bows with a cord using leather or rawhide booties…ha ha…Not reflexing to the amount that is done on here,but will reflex it more and more as time and bows goes on here.Twisting can occur but not if the limb edges are exactly even.

Reverse bracing with a string works perfectly. I wouldn’t bother clamping the bow into a rail from the tips. This could prevent the natural drying and reflexing from happening.
If bow gets twist from sinew, it is possible to remove by heat.

These are of course only my opinions…

They are sound to me.
