    After about 10 minutes of warming, (ok, it's hot now) the original 125+ year old balsam is melting and the 2 pieces came apart.

    After cooling in the pan to room temperature, I removed the lenses and put them on a paper towel to dry.

    Next step is to wipe the lenses clean with alcohol.

    More to follow.

    After cleaning both lenses with alcohol, I placed a small piece of blue tape on each of the "facing out" sides of the lens. Then cleaned again with a mild window cleaner to make sure all the old balsam was gone.

    Pressing both lens elements together caused the balsam to spread out to the edges of the lens. After double checking the alignment, I used a simple Craftsman brand pressure clamp to hold the lenses together as the balsam dries.

    More to follow when dry.

    Oh, and a huge thank you to Steven for his inspiration.
