If you are talking about the prop shaft (the part the rubber connects to), I'd say .0118" is too small. I use .013" marked, which measures more like .0135"

The material will also make a difference. Guitar strings work for me - and are cheap and readily available. I tried some stainless steel wire from Small Parts once that didn't work well.
