Hey - I have a beautiful Calcomp 1023 and last night both of the little rubber roller wheels broke. I suspect one was loose and it caused a couple of hiccups which then cracked the other one. It looks like the rubber was just old and worn out. I was wondering if anyone could point me towards a suitable replacement, either through a plotter furnisher or possibly a hobby shop? I have a full time job and don't have many free days to scout supplies, but I was thinking maybe a model supply store might sell little rubber wheels for cars and things that I could cut off and glue back onto the plotter rollers?

Many thanks,

fs
