the intricate dynamics of the TM opening and closing system.
But, to answer your question, I use a piece of yellow pine to assist with
the opening and closing. If you search on "My favorite piece of yellow pine"
you will see my post about it. I believe every TM owner should have their
piece of yellow pine, similar to mine.
Also, search and read posts about the opening and closing of the TM, and
also watch youtube videos. Much to learn, be patient, and take your time.
There are a few experts who have posted guidelines and instructions about
the lifting and closing, and maybe they will offer some tips...
I will offer one bit of advice, and that is: Do not force anything!
Some pics of your TM might help for understanding.
Keep asking, and you will get answers!
