Being my Brothers keeper...

[William]

Hello all!

I now, through Ebay; have become the owner of a somewhat used Brother 10Anniversary.

It seems to have an issue with the back side of the stitches showing alot of the thread from the upper side. Not nesting, but 8o% of the understitching was with the upper thread.

After performing a simple cleaning, blowing out and flossing  the upper tension I then removed the lower drop-in bobbin to find that the tension is, due to a small drop of epoxy over the screw, inadjustable.

The cleaning helped, but only a little.

I then changed bobbins and it helped a bit more, but it is still not perfect... The maschine came only with the bobbin that was in at the time it was sent to me - and certainly not the original!

My question --- is the Anniversary 10 unusually sensitive to the type of bobbin used?

Are there any other causes of unequal tension i should check into?

Thanks Muchly,

William David

You should only use genuine Brother bobbins.  Any slight variation will throw it all out. 
If there is excess thread showing on the underside  this is usually a problem with the top tension.  Make sure it is set on 4.  However it may be that it is as simple as not being the proper bobbin.

Soooo -

I bought a package of the Brother bobbins, dropped them in and everything AOK! 

Thanks
