Hi Fellow Windies.
Well yes im on my 3rd set of bearings in this PMG but my gripe was when the first went they did NOT keep bearings in stock that was in my posting back then, as of yet i have had no bearings from them Del, but to hell with them i buy SKF bearings the same size for my seed drill, so spares where not an issue, more a lack of them keeping bearings, but we are swinging home made blades on skate board size bearings, i sold one of my chinese units to a friend after 2 years service, and the BIG bearings where as new, and thats in a 200w unit, which by the way is not much more than a futureenergy unit, (and its a complete ready to use out of the box) geeeezzzzz i thought i was buying the rolls royce of PMGs and would be trouble free for years.
The last time i had it down i noticed all the white enamel paint bubbling with the salt air i guess, once again the chinese unit scores better with having a plastic shroud, over to top of the unit. As for fitting bigger bearings there is no room in the houseing to machine it out for a bigger cased bearing oh believe you me i looked ....lol.
My last correspondence with futurenergy i emailed to ask if they had a secondhand or shop soiled set of blades that i would try these i was prepared to buy, only to recieve a reply that they had nothing nor would they have, just a price for a set of new blades, and listen ....they are balanced to within 1 gram, but reading there website its is the user responsibility to balance.!!!!! Well i have done static balancing tests on my blades and they are fine, i even spun the complete unit up on my wood lathe with swivel headstock, and at 800rpm apart from blowing anything that was not fastened down into the air they appear fine, with no shaking or flexing, (a scarey job) but i least i tried my blade set to test for any imbalance. and all is well with them.
I have watched and studied my furling system in a gale and after some adjustments it too works to within expectations, it starts to furl just a wee bit later than my chinese unit, but in full force of the gale its fully furled.
I can only express my own problems wether they be unique or the fact they are just not up to the job as stated, well certainly not for up here.
To overcome my problems, i have just bought my 3rd chinese unit, imbalanced and noisy they are great, and besides its just a days job to re-work the blades as i have done in the past, just keep the welder handy for any fatigue cracks in the mast and tail fin, but i think 2 yrs hard work with no troubles and for the £230.00 delivered (as then) is cheap reliable generation.
But futurenergy are attending an exhibition in aberdeen, just 200 miles away, well guys ill be there with my pmg over my shoulder and a bag of knackered bearings, and ill be putting my case forward to them.
just keep her spinning..
