oh how I wish I could come help. My DH doesn't do anything when assembling ever, so if I buy something that has to be put together either I do it alone or seek the assistance of my eldest daughter. My dear friend has given me the strength to do such things by myself. It never ceases to amaze me what she does on her own. She even uses power saws on her own. She said the worse that can happen is needing a repairman later and she is right.
So give it a try, maybe call in a friend for moral support and to assist with taking pictures and writing notes.
