Kenny,

Since you say you are by yourself there, and are not familiar with working on such a gun...

I suggest you place the lock plate on a sturdy table, put it between a cloth, hold it with both hands, use your thumb over a small portion of the cloth, and push the hammer back until it clicks and locks back in place. Both sides must be cocked, in order for you to reassemble the gun. Be careful not push the main spring around, just hold the outer portion of the plate while pushing the hammers back in place.

Hope this helps.
