MNC ‘ebay special’ bullets

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   afternoon all,
Ive got 4 of the ‘ebay special’ MNC bullets mounted in each of my mt121s. I know theyre not great but for the price of them they do just nicely plus, the holes are cut in the battons now and it doesnt seem like theres much else will fit. Theyve served me well for the last 5 or so years but recently ive noticed the magnet, diaphram and bullet but are shaking loose from the mini horn. Anyone else had this issue? When mounted it seems to cause the bullet bit to sag - see pic

Its easily fixed, take the driver out and tigthen the screws (next pic). Any thoughts on how i can stop these coming loose again? If the screws are over tightened the cone presses into the diaphragm and it starts to crinkle. Would a bit of locktite do the trick without any detriment? Any other thoughts? 

Obviously not looking for answers like get netter drivers haha.

	I would suggest a smear of loctite on the parts that clamp together and also on the screws that hold it together. You can get different grades of loctite, green AFAIR is more of a glue and blue is for screws that need to be undone but stops them loosening due to vibration.

	I don't think Loctite will solve your problem. Really what you need is diaphragms that are the right size for that magnet However, you've got to be able to get those screws tight otherwise the weight of the magnet will always pull it off centre. Try a plastic shim under the diaphragm surround? Maybe it isn't thick enough to give the correct spacing (although it seemed to me problem was that the the coil former is too deep)
