I joined the Brother yahoo group when I got my machine. I tried searching there for a solution but didn't find one. I am not very good with navigating the Yahoo groups. The open part of the foot actually turns but is snug in some of the turn. I may see if my son-in-law, who is an awesome welder, can weld it so it stays in the correct spot once I get the plastic out.
I did buy a foot last night from Ebay. It is open and the seller listed the Brother 1500 as a machine the foot worked on. I will check and see if I can find a Janome foot if that doesn't work. I bought the machine from Ken's online store. We do have Brother dealer here, but they were $250 higher than Ken's.
