With some of the left over cuts from the 3 x 5 notecards, I will show you how I made a smaller logbook that will fit perfectly in a medicine bottle.
Again using those pesky plastic fake credit cards that I got in the mail, I cut one in half and trimmed it to fit the 1" x 2 1/2" cuts from the index cards. I put the logbook together the way I want it, top cover, middle pages, and back cover, and set the pile down.
Working from the top to the bottom, I punched the top cover first, then the inner pages, then the back cover. Remember that you can only punch about 5 sheets of the index cards at a time. If you try to punch more than that, it becomes strenuous to pull the handle down and punch through all of them at once.
This logbook is so narrow that it only requires two punch holes.
Pull the back cover from the bottom of the pile and place it on top of your pile so that the right sides of the covers are facing each other.
Loop your coil through the inner pages first, then the top cover, then the back cover and trim the coil with your wire cutters at the top end of your logbook.
Its not easy to show you up close what this looks like but there are lines on the base of your BIA that are labeled in inches. You can see some of the white lines to the far right of the BIA base. You want to set your size by the inside of the gap where I am placing the logbook. Since I am using the 1/2 inch size coils, I turned the knob on the end until the bar moved up to the 1/2 inch line. You can also measure the gap by placing the hard plastic cards that come with the BIA into the gap until it is flush with the size coil you are using that is pictured on the card.
Pull the handle down and squeeze the coils together. I have found that if I use too much pressure by pushing the logbook down into the gap, the coils will be out of shape after they are squeezed closed. The top of the coils will look flat and not rounded.
Flip the back cover over and to the back of the logbook to cover the coil in the back. Trim the ends of the coils so that there is no injury caused by the points on the coils.
