Needle Organizer for Leather Sewing Machine Needles

I needed to find a way to organize and keep track of my collection of leather sewing machine needles.

The problems were that the packets ended up all over the place, what to do with a needle that is still good but not new, and to identify which needle is currently in the machine.

I created this little needle wallet.  It fits the 10 pack of needles packets plus each pocket fits one additional needle.  In this way, a needle that has been used but not worn out can be easily identified and stored for future use.  I cut a plastic rod from a q-tip to insert in the pocket where the needle came from to identify which size is currently in the machine.  I suppose one could use different colored rods to identify needles being used in multiple machines.

Hope this helps.

New Automatic Bobbin Winder For Cowboy CB3200

I don't like the bobbin winder on the Cowboy CB3200 so decided to come up with an alternative.  The problem with a typical commercial sewing machine bobbin winder on a machine set up for leather is that it winds while the machine is engaged in stitching or, if not stitching, the stitching mechanism is running. Leather machines run rather slow and it takes too long to wind the bobbin and it seems like a lot of extra wear and tear on the machine.  Also, if left unattended, the bobbin doesn't wind with the thread evenly distributed on the bobbin spool.

I looked at several dedicated bobbin winders and found the Luis Sew model on ebay for $35 new including shipping.  This machine typically sells for $80 so I snapped it up.

Upon running it for the first time, I discovered that there is no speed control and the thing runs at warp nine... no control of the thread winding.  The tension discs are also too close to the bobbin which leads to uneven winding on the bobbin spool.

I decided to install a PWM (pulse width modulator) speed control which can be had for around $10.  The advantage of a PWM is that it maintains full torque while reducing the speed of rotation.  It also doesn't heat up the motor like a typical fan-type dimmer switch.

The machine also has a lot of vibration which creates excessive noise during operation.  I decided to make a new wider platform from 1/2" 9-ply baltic birch plywood.  I also mounted the motor on rubber washers.  The unit is now virtually silent.

So now the unit runs quietly, there is no vibration, the speed is variable down to zero RPM.  I can help the winding process manually to keep the threads winding evenly; it winds pretty well unassisted.  I have added nylon knee-high stockings to all of my spools of thread to keep them feeding consistently as well.

This unit works on type M, as well as residential type bobbins.

Hope this helps anyone looking for a better bobbin winding solution.
