I am handy with tools. Between me and my dad we almost got it on. We took it apart but we weren't able to get all the wat to the assembly (the only tutorial I could find didn't go that far) and I wasnt able to find exactly where the spring hooks on.
So the plan is to take it to the shop a couple hours away. Dad has a Dr appointment on Tuesday nearby so he will be in town. Hopefully they'll be able to pop it on with a bench service. Otherwise it will be 3 weeks until they can service it. We had the repair shop in our area close down not long ago and its given them extra work.
The good news is there's other machines I can use. Im currently getting to know the Janome sd2012. Its loads better than my Husqvarna that was probably in need of service when I last used it 10 years ago. I think I might like the Bernina better, which is fine because I think this one has been claimed for my cousin's daughter (They both were my grandma's), but Im happy to use it for now.
