Step 5: Making a base...
First cut the top off straight across with a hand saw so that you are able to get a good angle cut.
Second, hold your display board up to the spool and decide what angle you want the board to set and mark the spool with a pencil.
Now you will cut the angle with the hand saw and hold your display board up to it in a dry run to make sure you like the angle you have cut.
And the last step is to glue the spool to the back of the board (this is why you have waited to pain the back, so the glue can get a good strong bond, after the glue dries you can paint the back)
I used E-6000 jewelry adhesive, mainly because it's what I had on hand and because it's a good strong glue that will glue almost anything. I also propped the spool so that it would lay flat on the board until the glue dried. You can also tape it in place with masking tape until it dries.
