Geoff, I'm assuming the standards, or lack of them, are the same across China. I think it would be advisable to have any Chinese made extractor checked out. Or usall could be zapped. If the other two in town who bought the 4 frame model find that problem, I might take more action, such as alerting our bee club.
Jim, I get used to some of your lingo but every so often new misunderstandings arise. When I went to america, I was looking for minced meat to make rissoles. It took a while to realise I should have been looking for ground meat to make patties.
Wombat, mine is radial. Wouldn't all extractors fit full depth frames? Do you have an extractor?
Chriso, I am very lucky to have a friend who is a sparky. The other day someone here was charged hundreds of dollars to have a fridge fixed because the tradie came out 3 times and charged a hundred or so each time just for the home visit.
It would be a shame if we did not have access to affordable extractors here. I have not seen anything remotely similar that is made in Australia. You might pay 4 times the price for a smaller extractor. Ours cost a couple of cows, but we'd have had to sell the whole herd to buy one made here.
