Problem with Biax scraper after rewinding
I just drove to Brisbane to pick up my 7elm Biax from Braithwaite electrical and now the assembly that reciprocates moves back and forth freely. when I turn the scraper on it doesn't move but if I apply pressure to the blade holder it does. I paid $700.70 to have it rewound from 110v to 220v but they're also put new bearings according to the bill ($11 each which seemed uncomfortably cheap), could they have have put the wrong bearings in shifting the position of the armature in relation to the mechanism or assembled it incorrectly?
I never tested it before dropping it in as I don't have a transformer but the bladeholder assembly was definitely not like it is now, you couldn't push it back and forth freely like this. I tested it while I was there and when it didn't work the tech came out and told me you had to press it in to make it work which doesn't seem right at all. The only experience I've had with a biax is at Richards class in Denmark so I'm a complete novice and might be missing something obvious so any advice would be appreciated.
(reposting from PM hoping any Aussies here could help)

Stupid comment possibly, But are you sure you have a scraper and not a flaker. I Had a go on one at Machtools scraping class and you had to push that to make it work. RC had a thread on pm taking his apart but the pictures may have vanished. Best of luck hopefully it works for you.

definitely not a flaker, had a closer look and there's witness marks on the gearbox so I assume curiosity got the best of them and they took the whole thing apart. Will call in the morning and try and get hold of the tech that took it apart to see what he's done.
