You have 1 dowel and 1 bolt?
How loose is the bolt in the hole?
Brace it again and measure both sides like this.
The shorter measurement limb, needs to be the bottom limb, tell me the measurement's?
This is your next step, but lets get the limb stuff first.
After you get that done you need to put the string aside and get the limbs straight, check and double check.
Use the center jig to drill threw the limb and into the riser close to the bolt.
You can put a overlay on it later.
