Ok so I finally got round to fitting it and thought id give it a run for it's money and have to say was quite surprised with the results had it in the shop yesterday and tried it out on some b&g .was as smooth as my trusty neds and I didn't have a problem packing the solid areas in by just turning the screw for more of a punch . I thought I'd leave it for lining the now but may try at a later date all in all I'm fair impressed for it been a mod on a cheap machine .probably even better on a real stealth or Swiss plus forgot to add the simple bar tensioner works a treat and does what it's supposed too pic to follow
