Welcome to the Quilting Board!
Candace, Thanks for posting the tutorial and helpful info on the Elnas.
At first, I couldn't get the link to show the info, so I took the elkgrove portion of the link to look for the link on the Elna repair.
Your orchids are very pretty!!!
Anamaria, Did you figure out how to get the hand wheel off that machine? What is the machine?
I think the previous post was correct, it looks to me like the small pin in the. Center of the shaft will have to be driven out with a drift pin pinch. Preferably one with a "hollow" end. A flat punch will work, but it would deformed the nicely rounded end of your pin.
When I am not sewing or working on sewing machines I make mine furniture in 1/12 scale. I would like to show you a few pieces. These are my wife's parlor furniture in miniature. The mini-table is setting on tip of the full size table
