I'll send up some prayers for your little finger. Those kinds of things throb so badly.
I cleaned up the 404, took it to a sewing day and brought it back. The tension is too tight, the pressure on the presser foot was too tight and the doodad that raises the plate around the teeth was frozen. That one I don't need except for cleaning. A pair of pliers and a bottle of gun oil and we are in business. Now to play with the tension. I want to leave this one at church, but not if it isn't sewing perfectly. Have my 301s spoiled me? When I take it back, it will be carried in without the case. The machine isn't heavy, but the case, which is in perfect condition is very heavy.
