Hand wheel is stuck - Sewing Machines

hi Tamara.
you have not said the make or model.but try this.
Make sure the push your bobbin winder to the right then to the left and see if that solves the problem. Your Old Machine has a Clutch & It Needs to be Released. The Clutch is this little dial that is inside of the hand wheel. In older machines, it was used to wind the bobbin without the needle going up and down.17 Jul 2015

Help My Needle Hand Wheel are Stuck Sewing Machine Jammed

Make sure to clean/remove all the lint, thread, dust, etc. that may have built up in the bobbin area, around the feed dogs, and under the needle plate. Sometimes gunk build-up will prevent the hand wheel from turning. Remove the bobbin & bobbin case from the machine and the needle and see if the hand wheel will turn. If not, then it may be time for service.

My hand wheel is hard to move and will not make complete turn unless...

Help My Needle Hand Wheel are Stuck Sewing Machine Jammed

..

Check to see if the needle is jammed into the fabric. Try pushing the REVERSE on the machine and give a little push to the hand wheel.

Still too vague... Make and Model and more detail PLEASE

did you get all the broke needle out of the machine?

try some wd 40, spray it on the area of the take up lever & let it set for at least 10 minutes then with the hand wheel on the right hand side slowly move the hand wheel toward you & if it still doesn't move re spray again & wait again then try the hand wheel again to move toward you eventually it should start to break loose if it's just stuck.
since you pruchased it at a estate sale, there not much telling when the machine was serviced last
if the spraying doesn't work, consider having it serviced

hi there,
well,stuck up hand wheel, is due to mechanical obstruction inside machine,bushing on shafting need to oil,and on handwheel bushing near clutch there is oil port there. since hand wheel are connected to cam shaft with set of gears and pulley is coupled to motor pulley,and other linkage under bobbins,shuttle race etc,broken gears are most common causes of stuck up handwheel,we can consider also the brush carbon,when worn out and damage the rotor commutator brush.if you can open the cover of motor below side of handwheel,you can see the pulley and motor assembly.also on top of machine there an opening to see the top gear assembly,this should be done by service technician.try to bring to nearest service center if still under warranty claim this for lesser maintenance cost.have a nice day,don't forget to rate me.thank's.
