Mostly just a cathartic vent here..... ....unless anyone has tested/studied these things extensively enough to contribute to my musings. Have searched BYC and not found much of anything other than 'buy a new one'. So I ordered a new one. Have 2 that are not working in a heated incubator. Tested one both not loaded and fully loaded at room temp on table top, even took pics at timed 30 minute intervals so as not to miss anything and be able to review motions/positions. Everything looked pretty good...except.... ....there was some hesitation at one far position and motor shaft linkage appeared to be creeping off motor shaft but was easily pushed back on. Great, I'll just keep an eye on it. Well, once in the bator and all heated up that didn't cut it...shaft linkage was way down shaft and very difficult to push back on. After taking it off found it had been rotated past the flat on the shaft. So I took it out and replaced it with my turner(first one is a buddies I am hatching for). Now my turner appears to have crapped out. ..and I really wonder if it's was working the last hatch I did, I have never paid this much attention to it but my buddy said they had trouble with it so I was watching carefully(obsessively). Now I see, in the middle of writing this tome, that after an assumed 18 hours(didn't check it while sleeping from 10p-6a) of being stuck in one place it's moving again I did give it a wiggle. Maybe there's a pinch/binding point at end of stroke due to motor mount misalignment?? I now have buddies motor off turner and plugged in, it is turning at rate expected but making a racket. An.y.way...... If you've read all that, are still interested, and if you have paid close enough attention to really know my main questions are: -Does the motor make noise when working properly? -Is the heat of motor normal? It's not too hot to touch, but still. Guess I'll know those when new motor gets here and I plug it in to test it. -Anyone ever taken one of these things apart...anything repairable in there?? -IS there's a pinch/binding point at end of stroke due to motor mount misalignment?? There is some slop in the clearance holes for motor mount screws. There's a lot of linkage points on turner mechanism and they all seem pretty loose(not binding)...until it get to that supposed pinch point. Off to find something to do other than bang my head against this issue(yeah,right).
