This is a machine I purchased on ebay, supposedly refurbished. Only a few days after using it, however, the stitch selector stuck. Thanks to this forum, I was able to fix this with a little lubrication. However, the hand wheel has been stuck since the beginning, although I could still wind bobbins. Today, however, the bobbin winder isn't winding at all. I suppose it needs some oil too. Can anyone show me a photo of where to put the oil?

I did find information on how to fix the handwheel. Haven't done that yet. Sigh. I love this machine (was using my mom's for several weeks to make masks). 

Thanks in advance for your help!

Welcome!  I personally only collect older machines but there are lots of folks here who collect the electric machines. 
We tend to be very visual folks so pictures of what you are working on can help a lot.

It's hard for me to tell exactly what your problem is with the bobbin winder.  The Rocketeers are known for finicky bobbin winders and many times the spring is broken.  On mine, I complete disassembled for cleaning and reassembly has to be just right for everything to work.

Andy Lube on YouTube has some very helpful videos on the Rocketeer, including the bobbin winding mechanism.  

These machines need to be really clean internally- all the old oil and gunk removed - to work in prime order.

Welcome and best on getting everything operational.

Regarding the stuck handwheel, from a recent thread on a groups.io: heat via a hair dryer to loosen the handwheel, or use a non marring rubber strap wrench. Then take apart and clean.

Sounds like a job for a repairman. I was hoping it was something I could do myself. Oh well.

A manual and associated oiling and lubricating points can be found at https://www.singer.com/support  by putting 500 in the box to the left of the red "View Manuals" button and then clicking it.  It will be the first one on the page.  I have trouble with some of my links, but I think https://res.cloudinary.com/singer-sewing/image/upload/fl_attachment/Singer-Website-Library/outdated_product/1308_500_0.pdf will take you directly to the pdf.  Lubrication is done with a grease such as Tri-Flow Grease or even just Petroleum Jelly for the gears.  Oiling is indicated by drops and should be done with Sewing Machine Oil or Tri-Flow Oil.

The service manual can be found at https://sewingdude.wordpress.com/2012/09/07/singer-500-service-manual/

Hey! Yeah I just posted over on vintage singers a couple days ago about this. I recently did a total teardown and rebuild of a 500A. 

The handwheels seem to get stuck to the outer wheel (technically the "stop motion nut") more than is reasonable. Taking it apart, cleaning with KrudKutter (especially the clamp washer listed as "C4" in the service manual) and putting it back with very light oil seemed to fix the problem for me.
As for the bobbin winder -- oil on the rubber tire will actually make it slip and not wind. If you take the top cover off, you can see that when you press the bobbin winder lever to activate it, it presses the rubber tire against the very tip of the motor shaft, which has a spring wound around it for friction. If the tire is too old or too greasy, there won't be enough friction, and the bobbin winder won't turn. It's a weird setup and prone to actually getting *worse* with oiling, which is counterintuitive. Cleaning the tire and the end of the motor shaft with some alcohol, and/or replacing the tire, will likely get you back to good. The *inside* of the winder, the shaft of it that spins, does need a tiny bit of oil, but again caution not to get it onto the tire...

Hope that helps!

Don't give up - with the great resource you've been provided here - likely the fix will be easy and something you can do.  Manuals, YouTubes, and hearing from others will get you a long way.

Lubricating, taking the handwheel (balance wheel) apart to clean and lubricate, and inspecting the bobbin winder all are easy things you can try.  If none of this works than please get back to the group and provide photos if possible.

The Rocketeer is a great machine and one of my favorites - it's definitely worth learning to get it up and running and some basic maintenance procedures.

Good luck!

Barbiesa, you can do this! These are the "easy issues" to fix, and you will find a great deal of satisfaction in learning, doing, and completing these small repairs. Do consider trying! Take photos of your steps, and remember we will help as you discover and reassemble.
