So you do have to move the insert. Thanks for confirming that. I can just get my hand in with 2" of space.
With the Brother 1500, I took the door off the bobbin compartment.
Since the Koala is a standard table (fits Pfaff 2170), I won't be able to get an insert. I'll have to find a table that I can take the legs off and adapt. Gaposis lets the fabric drop through.
