My Table And Chairs

I bought a dining room set from my friend.  The table is big, six foot and that is before you put the leaves in.  It is a beautiful set and since we have four kids, it was perfect for our family.

The only problem is that the chairs started coming apart at their joints. I found some clamps I wanted and wonder if I can do this by myself.

Normally my husband does this type of thing and I leave him to it.  I don't know, do you think I should try this on my own?  What would you do?
