If you don't understand it and or get confused, I better have another look at it to see if I can remove the confusion. My writing is no good if you can't understand it.
The plastic hinge piece on the forearm needs to be fitted really close. The four thin wedges will be glued to the fore arm wood only. With the forearm held in place with the forearm screw the wedges are tapped in so that the hinge piece is tight against the action or rather very snug.
Make sure the wedges are not glued to the hinge piece too, apply release agent to the plastic hinge piece. Clean it well before the bedding in your next step.
Once the wedges are glued solid, you remove the fore arm making sure not to disturb the wedges. You then mix your steel bed and apply it to the hinge piece and the wood and put the forearm back on with the screw. At this point you can rotate the forearm to line it up with the hinge piece and let things set up.
After that the two wood screws are reinstalled. Next step is to solid bed the hinge piece and bit of the stock and the forearm tip. Shim the stock screw so the stock is parallel with the barrel and the stock has 1/8” clearance between the two bedding blocks. No clearance on the sides. Or very little.
Once the bedding blocks are set up solid. The space between the blocks is now filled with Silicon caulking of Dow foam. The screw is now tightened to actually bend the forearm up and puts uplift on both the front and back block. Mark the screw to see how much up lift you get use a scale on the fore arm tip, you want about 15lbs uplift.
Once you have every thing lined up and tensioned correctly mark the screw position
and take the forearm off and steel bed the screw lug on the forward edge and bottom. Apply release agent to the lug and put the forearm back on. You are done.
