The 10 presser feet which would have been included as standard with the 830 are as follows:
000 zigzag 0
470 overlock 2
452 buttonhole 3
007 zipper 4
016 blind stitch 5
030 embroidery 6
419 tailor tacking 7
285 darning 9
168 hemmer 68
003 lap hemmer 70
The first 3 digit number of each row is the original number designation, which was stamped on the top of the front of the foot shank. In later years Bernina changed the numbers on newer feet to the number in the third column. Things get even more confusing when you learn that the same feet, supplied with earlier Bernina machines, often did not have any numbers stamped on them at all.
The 'old' style feet have 2 prongs visible at the top front of each foot; old feet fit Bernina models up to the 1130 (iirc- but it's late so don't quote me on that lol).
'New' style feet have no prongs, just a flat front 'lip' at the top front of each foot, and fit newer Berninas.
These feet are not interchangeable - the new feet will not fit the old machines, and vice versa.
(Incidentally, the 'old' feet can be split into 2 types - those with a 'thick' pair of prongs, and those with a 'thin' pair of prongs.
The thick prongers are 'older' old style, while the thin prongers are 'newer' old style....!
But they would both fit the 830).
Confused yet? lol
The 'old' style feet can still be purchased new (-they will be 'new' old style, with thinner prongs...) from Bernina dealers, as the modern (mechanical) 1008 machines still take that style of foot. Expect to pay on average upwards of £30 for a brand new foot.
Personally I would say that the most important feet would be:
1. zigzag
2. overlock
3. buttonhole
4. zipper, and
5. darning (-which can be used for feed dogs down/free motion sewing too).
A set of these 5 feet would be an excellent start to your daughter's Bernina foot collection, and possibly would be all she would need for now.
...Although please someone chime in here if you know what she would need specifically for the content of her sewing course... I don't know what the course comprises, and I'm just going on what I use most with my sewing.
There are gazillions of Bernina feet out there, the scope of the range is astonishing.
If you begin to collect them, you may develop an obsession for them, and be unable to stop...
Also make sure the bobbins you buy are the right size; the old genuine Bernina bobbins always had a 'BB' stamped on them. Helen Howes has a few of these for sale on her website, at £1.50 each I think.
Generic bobbins that fit have 7 holes on the round ends. I have not had to buy new bobbins but from what I have heard the quality of the generic bobbins can be pretty ghastly, and they can damage the hook and race, so it may be best contacting a Bernina dealer to see what they recommend, that is if you need extra bobbins.
Plus you will need a Bernina needle unscrewing tool; they are the little black things. I can post a pic if you need to see one though.
Actually I meant to post some pics of the feet, but I ended up photographing the wrong ones... duh... so I'll do that another time.
Barny - I have more .pdfs of info and pics of Bernina feet, as well as the 830 user manual (-which has excellent instructions for each foot originally supplied with it), and also the 830 service manual.
If you pm me your email I will send them along to you, as well as the the other manual I have for you
