Remember the E core I shown you on previous post?
According to the Uncle that teach me to do winding, we can't do the winding in the core. We must first make a bobbin, do the winding in the bobbin, then only take out the winding and put it into the core.
Note that, bobbin are usually made by plastics or woods. The model that I show here is not the common way of making a bobbin. This is a self impress creative babe's idea to do a one time bobbin. If it happens to be very useful, don't forget to let me know.
First design the measurement that we wanted. Some place must the slightly longer and some place must be slightly smaller so that the winding can still fit in the core after the winding is coated with insulated.
I use Model board to do it. Sort of recycle item.
Then, use white glue to attach them together.
I compress the glued model board so as to minimize the space/length take up by glue when it stack up.
This is how to bobbin looks like. I did 4 sets, but I only manage to finish 1 winding. Will take about that later on the next post.
