Question about Sewing Machines
I have a Bernina 950 which I have been using in my dressmaking business for about 2 years. I recently purchased a twin needle post so I can neatly finish garments but I can't seem to get the single needle pos tout of the machine to install the twin needle post. How do I do it?
Sounds like you purchased and wish to use a twin needle which comes as two needles on a single needle shaft, correct? That is terrific and you have a wonderful machine.
Remove the needle in the machine just the same as you have been over the past 2 years. Unscrew the needle clamp screw, pull down on the needle or part of the needle in the machine and insert the new twin needle shaft into the needle bar. Tighten the needle clamp screw and thread the needles using two sources of thread on the top.
If the existing needle post is not coming out of the needle clamp easily, use a pair of pliers to grip and pull down. Cover the sewing surface to ensure that it will not be damaged as the pliers free the needle. If the needle is firmly embeded, you may need to give the pliers a gentle tap with a small hammer.
If using a zig zag stitch make sure that the width does not exceed the twin needle limit; otherwise as the needles swing from side to side they can hit the stitch plate and brake.

Make sure the chain stitch thread is threaded exactly as it should be, make doubly sure the thread comes off the bobbin vertically and runs through all eyes smoothly. Any faults in the threading causes extra tension at the needle despite what the tension is set on.
If this is not the cause then the needle depth and the looper timing needs checking.

It could be that there is a loose piece of thread, or some fluff which is obstructing the tension gauge. Try blowing around the theading area (or even run the hoover pipe near it to see if you can **** it out). I cleared mine by folding a piece of non fluffy material and rubbing gently between the tension dial and machine.

You need to use the zig zag or satin stitch presser foot with the twin needle. You also need to make sure you have the zig zag plate on your machine. Also, remember when using the twin needle, you cannot put your stitch width beyond half way. The best thing to do is once you select the width, turn the handwheel to see where the needle is going to hit, you want to make sure it clears the plate or it will break.

most domestic sewing machines use 130/705h system needles - buy a pack each of size 70, 80, 90 and 100 to start. if you plan on sewing knits (stretchy) fabrics then buy a couple packs of ball points in size 70 and 80. put in a new needle for each garment you sew as a needle goes blunt in about 6 hours depending on what you are stitching. visit www.sewing.about.com and check out sewing machines 101 and debbie's article on sm needles for more good info. depending on what your heavier weight fabric is you may need to use a 110 size to handle it. the denser the fabric the bigger it needs to be.

if you want to sew pin tucks, then yes, you could use that foot providing the hole is large enough for the two needles to pass through. Twin needles come in 4mm gap and 2.2mm gap so just check that it will fit. When using a twin needle, there is a lot of heat created so it is always important so sew slowly, going too fast will cause the needles to break.
Also, you should check on the twin needle type, modern machines now using a twin which is slightly offset, the block colour is usually a dark brown/red colour. Your machine may have come with a twin needle in the needle selection so take a good look at it and see if it is an offset one, then make sure you buy replacements of the same type.
THe pin tucking foot allows you to keep rows of pintucks lined up, it will have grooves in the base that you can run the previously stitched pintuck through to keep even distances. Best on lightweight fabrics like cottons, lawns, batiste etc. You'd probably go for the narrow 2.2mm twin needle to get a nice fine tuck. I like to press each seam after stitching too to give a sharp tuck.
