this is my first visit to this group, i was given a brother profile
831 machine that someone was going to throw away. it has sat in an
outdoor starage shed in Tucson, Az for at least 13 years, I have no
books, and no attachments for the machine. so far what i have done is
oiled everything i could see that moves and replace the dried out
belt, and needle. But i cannot seem to get the tension set on either
the bobbin, or the needle thread. I basically need to know where to go
next.

please be gentle on me as the last time i did any sewing was back in
highschool in the 60s

TIA
Gene

Start by studying the tension for the UPPER thread: are you sure the
thread is properly seated between the tension disks? They should look
like two saucers back to back, and the thread goes between them. Floss
the space between them with either something like a spectacle cleaning
cloth or some thick lint free thread, then re-thread the machine.

Then take a good look at the bobbin and bobbin thread. Now, if this is
a drop-in bobbin, just drop it in the bobbin space, and make sure you
pull the thread into the leaf spring that sets the bobbin thread
tension. It should unwind off the bobbin in a clockwise direction.
Pull the thread up to the top side of the stitch plate by holding the
loose end of the UPPER thread and turning the top of the handwheel
TOWARDS you: pull up the loop and put the tails behind the foot.

If this is a take-out bobbin case, again, pop the bobbin in the right
way round (anti-clockwise thread as you look at the open end of the
bobbin case), and pull the thread through the slot and under the leaf
spring. Re-insert the bobbin case, pull the thread up through the
stitch plate (always wind the top of the handwheel TOWARDS you!), and
try again.

If this doesn't work, get back to us.

i used some old yarn and got that part cleaned out just fine. also
followed a link from way back that helped me thread it properly.

same link told me i had the bobbin in backwards, got it adjusted so it
pull out just slightly, however now i cannot get the upper thread to
latch the bobbin thread. ( a relative suggested this might be a
"timing" problem)

Come and join the Yahoo group, Wefixit!

To see if you do have a timing problem, thread up and leave the 'door'
open so you can see the needle and thread in the bobbin area: turn the
machine over by hand, and if the hook doesn't catch the thread at just
the right point (probably when the needle is at its lowest) you may well
have a timing issue. The Old Sewing Machine Guys (some of whom are
ladies!) on wefixit are great at helping out with this sort of problem.

You need a couple of inches of thread sticking out from the bobbin
tension for the upper thread to pick up. Also, the bobbin tension is
not very tight...somewhere around 20 grams of pull.

You can roughly check the timing by taking out the bobbin case and
turning the handwheel. The hook should pass just above the eye of the
needle when the needle has risen a couple of millimeters from its
lowest position.

Two other things to check are whether the needle is properly inserted
and whether the needle is properly threaded.

If the bobbin case is inserted from the left end of the machine, then
the flat side of the needle likely goes toward the right side and the
thread goes through the needle from left to right. If the bobbin case
is inserted from the front of the machine, or it's a top-loading
bobbin, then the needle would be inserted "normally" with the flat
side at the back and the thread inserted from front to back.
