Feed Dogs- metal or rubber?

The only home sewing machine ever to have the rubber feed dog was the Singer touch and swear. In most cases they can be replaced with metal ones once they wear off and the will. They were made like that as in the late 60's and 70's with all that shiny disco fabric some genius thought it would work better. Not so needed now a days.

All 12 of mine, sergers, broken Cub 8, and working machines from 1090 to

The metal teeth on my machines have never damaged the sequins and stuff or the gold lame that I have sewn. For some more delicate foil prints you might like to use the old trick of strips of Izal! :)

I have several, about 9 machines that have or had rubber feed dogs. Most are the 700 or 900 series. They were great when new but did deteriorate over time. Some are still in excellent shape and I do like them for delicates and some heavy weight fabrics too. But most I have since replaced with metal ones because of the rubber falling apart. You can still get replacement ones though , often on ebay and not expensive either. They are very nice for delicate fabrics.

What is Izal? I use the pieces of pattern tissue that are not printed on (the pieces between the pattern pieces)

The only plastic ones I've seen are those on the HV walking foot - and they are almost as hard as the metal ones! :)

Otherwise known as Government Unsinkable loo roll! ;P

Looks and feels like rolls of tracing paper, it's medicated torture for the bum, but perfect for sewing if the rolls are sliced about an inch wide.

Yes but expensive
