Spinning wheel drive ratio – getting down to the nitty gritty, and learning to control my tendency to over-spin yarn

Spinning wheel drive ratio is the number of times the bobbin revolves whilst the drive wheel makes one revolution. It is governed by the size of the whorl that drives the bobbin. There is of course the effect of any brake to be considered as well, but this has to be adjusted to get the yarn to wind onto the bobbin and is not the same as the drive ratio.

Most modern wheels offer different ratios by providing several different sized whorls on the bobbin or flyer. Probably because my upright double drive is an old wheel, and I mean old, wobbly and fragile – one that would be termed ‘vintage’ on eBay, it only has one ratio (it only has one whorl on the bobbin). I tend to over-spin when using this wheel, so I wanted to teach myself to make softer yarn and thought understanding drive ratio might help me. Being a bit techie and liking to understand how things work, I decided as a first step to check out what the drive ratio is on my upright double drive wheel.

Using advice from ‘Spinning Wool – beyond the basics’ by Anne Field, I started the process. Firstly I removed any yarn from the orifice and bobbin and slackened the tension screw to the lowest setting. Next I tied a tag of yarn on one arm of the flyer as a marker, and aligned this arm with the rear maiden. Now, using my hand I turned the wheel one complete revolution, counting how many times the tag of yarn passed the rear maiden. This figure is the drive ratio of the wheel as it is set up (remember that a different sized whorl will give a different ratio). In this example, the bobbin revolved 6 times during one revolution of the drive wheel, which means that my old double drive upright wheel has a 6:1 ratio.

Next in my experiment to spin softer yarn I trawled further advice from Anne Field. She suggests that the fibre itself can give you information as to how to spin it, and that frequency of crimps along the staple length of fibre can give you a clue about how the twist frequency. In her opinion a fibre with 7 crimps in 2.5cm, for example, is best spun with 7 twists per 2.5cm of singles. OK, I thought, so I pulled a staple from the Shetland fleece I am working with, and counted the crimps per 2.5cm. I used a magnifying glass to help me, and came out with a figure of 5 crimps in 2.5cm, which meant that I needed to aim for 5 twists in every 2.5cm of singles as I spun the fibre.

Once again I referred to Field’s book, and from the suggested methods for establishing a visual reference for the distance in which the twists should lie, I chose to mark 2.5cm on a piece of paper. I then taped this my lap whilst spinning. Other methods included marking these lines in your spinning apron, or using points on your fingers, e.g. tip of thumb to knuckle. This last one is the one I plan to move to once I am a bit more confident.

To re-cap, my aim, based on the Shetland fibre’s crimp, was to have 5 twists in 2.5cm of yarn. This meant 2.5cm of twisted yarn had to be drawn onto the wheel during one revolution of the drive wheel (5 revolutions of the bobbin), thus 5 twists would be inserted into that set length of yarn.

Anne Field estimates that approximately 1 twist will be lost in each 2.5cm of singles once the yarn is plied (although I am a bit hazy about how that happens), and so it seemed to me that I could spin the yarn with 6 twists per 2.5cm and finish with the 5 twists I wanted. This fitted in really neatly with the wheel’s drive ratio of 6:1, (1 treadle, and therefore 1 revolution of the wheel, turns the bobbin 6 times). This made me wonder whether this wheel was designed and made for spinning this type of wool from the older British breeds.

So by treading SLOWLY, drafting 2.5cm of fibre and releasing 2.5cm of yarn into the bobbin for each revolution of the drive wheel (one pedal motion), I actually managed to make a start.

To check how I was doing I stopped after a few metres of singles, pulled some back off the bobbin and let the yarn twist back on itself to emulate the final plied yarn. After evaluating the twist, and adjusting my spinning accordingly, I eventually managed to achieve approximately 5 twists per 2.5cm! Yes….I was getting it – slowly.

The resulting yarn is so much softer and fuller than my normal attempts – and a small hank is now drying in the bathroom for me to evaluate tomorrow.

My next step is to lengthen the draft and feed 5cm of yarn onto the bobbin in 2 treadles (revolution s of the drive wheel). In theory I can increase the length of draft and feed depending on the length of fibre I am working with, providing it has 5 crimps per 2.5cm.

I’m not sure what happens if there is more or less crimp, and therefore more or less twist required in 2.5cm. That is my next learning curve.

I may I have made some mistakes and probably over generalised, so welcome comments and advice.

Beware pin pricks

Two weeks ago I poked a pin underneath my left index fingernail, painful, but a common occurrence. I thought nothing of it. Then a week later my finger had become progressively more painful to the touch. I was away from home and didn’t have any antiseptic with me so hoped it would calm down. However the side of the nail went black and the top of my finger – above the last knuckle – became red, swollen and began to throb. ‘Uh oh’, I thought, that looks, and feels, infected.

Once home I applied Magnesium Sulphate, but eventually needed antibiotics to bring it under control. Now my finger has drained and is on the mend, but it was a silly thing I could have avoided. I did the same into my thumb over the weekend, so I was straight to the TCP antiseptic this time.

So learn from my mistake, and remember that it was only a tiny pin prick that led to all that.

Don’t scroll down if you don’t want to see the repairing finger. The bandaged appendage severely hampered my hand knitting and sewing activities and it still catches fibres when knitting as it heals.

Annoyingly this catches on everything, but I am trying hard not to pick at it.

Today is beanie day …

OK, I know it’s now mid January and this is a post about a Christmas gift but I’ve only just got around to finishing it off and getting it online. This is the story of knitting the hat worn in this photo.

December 2018…

I’ve started a beanie hat as a Christmas gift. Its in yarn from my stash, a rather nice airforce blue tweed 90% wool 10% acrylic blend Aran weight yarn. I dithered about the acrylic content I have to say, as I believe one’s toil is best rewarded by natural fibres, but the the colour (and having the yarn to hand), won the day.

The brim should work out to be around 7cm (3″) deep, and I’m going to knit it in a 3 row 2×2 cabled rib, with the shaped crown in stocking stitch. The pattern has been designed for a 61cm (24′) head circumference.

Gosh that doesn’t look very blue, more grey, must be the light. The rib shows though.

The cabled rib is worked on a 3.5mm circular needle, and the crown on a 4.5mm circular needle.

I have a set of those lovely interchangeable KnitPro needles, which means the world is my oyster when using circulars, but because the yarn is quite dark I have decided to use a white Prym triangular pointed circular so its easy to see the stitches. These are also comfortable to work with, and have a strange knob on the point that I quite like.

So far I have cast on 80sts (has to be divisible by 4 for the 4 stitch rib repeat) worked 2 rows rib and 6 repeats of the cable, and then 6 rows straight rib. I used the 2×2 alternate rib cast on recommended by Woolly Wormhead. Its not as stretchy as I had hoped, but looks good. Any stretchy one will do though, don’t beat yourself up about it.

How to work the c2b cable on the rib: Either use a cable needle, or work them as follows: slip the two knit stitches one-by-one knitwise, then insert the left needle from the right into the front of these stitches and slip them back to the left needle. This twists the stitches. Knit them one by one.

How I knitted the hat:

Cast on 80sts, using a stretchy cast on.

Join the round securely in your favourite way; for example work the first stitch, and pull the yarn to tighten the join before working the next stitch, or before working the first round slip the first stitch of the cast-on onto the point of the right needle so that it will be knitted at the end of the first round.

Mark the end of the round with a stitch marker.

Round 1 and 2: (k2, p2) to end.

Round 3: (c2b, p2) to end.

Repeat round 1-3, 5 times.

Round 16-20: (k2, p2) to end.

Round 21: purl.

Move the marker up to the current row.

Now you have the option to work all the stocking stitch in purl, and replace the knit decreases with purl versions, or if like me you find knit faster than purl, this is what I did.

Slip the last stitch to the left needle, and take the yarn to the back between the stitches then slip the stitch back so that the yarn is caught around the stitch. Invert the knitting and working in the opposite direction to former rounds, work the rest of the crown as knit stitches.

Round 22: knit

Continue working as Round 22 until the work measures 20.5cm from edge of rib.

Now to do the shaping.

I worked the first and every fourth round as a decrease round as follows.

First round,: k7, k2tog (70)

Second and third round: k all.

Fourth round: k6, k2tog (60)

Fifth and sixth round: k all.

Continue in this sequence, knitting one less stitch between decreases until 50 stitches on needle. Then work decreases on every second round until 20 stitches remain, finishing with a knit round.

Break yarn leaving a 40cm tail. Thread yarn onto a darning needle and slip the open stitches onto the darning needle. Draw the stitches in and secure the yarn end.

What’s inside ‘Translating Between Hand and Machine Knitting’?

Lace knitting – see more about this on my Translating Between Hand and Machine Knitting page, but in brief, yes this is explained in loads of detail, with helpful photos and diagrams, examples and step-by-step instructions.

The book does not include garment patterns, it explains how to knit different stitches by hand and machine, and why some stitches are more suitable for hand and others for machine knitting.

Hand and machine knitting – using a ‘lifeline’ when knitting lace

When hand knitting lace it is so easy to make a mistake or drop stitches, even on the plain rows, (I have a habit of dropping the yarnovers).

To save yourself the hassle of having to unpick and rediscover your pattern, adding a lifeline is a real life-saver; although it may seem tedious at the time.

A lifeline is a piece of thread passing through all the stitches along one row of the pattern so that if a stitch unravels some rows above it cannot drop below this retaining thread.

Decide where you want the lifeline to be, this would usually be at the end of one full vertical repeat of a lace pattern, on a non-patterning row, (usually a purl row). If it’s a short lace pattern repeat that is only two or four rows high, then you might put a lifeline in after every four or five repeats of the pattern.

To prepare and insert a lifeline:

  • Choose a contrast colour that’s no thicker and preferably thinner than your knitting yarn. On fine lace sewing thread is ideal.
  • Cut a length of yarn that is 20 cm longer than the width of your fabric.
  • Thread the yarn into a large eyed bodkin sewing needle. Avoid using a needle with a sharp point as this may split your stitches.
  • Using the sewing needle thread the yarn along the stitches on the needle, making sure the thread goes through each stitch.
  • Pull the lifeline gently so that there is an even length of thread at each side of the knitting.
  • Remove the bodkin sewing needle and knit the row as normal.
  • Once you have threaded another life line in place at your next chosen position you can remove the first one.

You can use a lifeline in exactly the same way when machine knitting, it is just a little bit more fiddly to thread the yarn through the stitches. But believe me, its worth it!

The image below shows a lifeline (yellow yarn), being inserted into lace knitting being worked flat, but using a circular needle. A circular needle has a thin wire in its centre (in this case its a red wire), and sliding the stitches onto the wire before inserting the lifeline creates more space inside each stitch, making it easier to thread the lifeline through.

A lifeline being threaded into lace knitting. Insert the lifeline after working a plain row. This gives you easily recognisable loops to work into.

‘Translating between hand and machine knitting’ is about to be published

i have just received my pre-publication copy of ‘Translating between Hand and Machine Knitting’, it was waiting here on my arrival home from holiday. It’s a great welcome home present.

Holding the book
My pre-publication copy just out of its wrapper.

Here are some sample pages.

Translating between Hand and Machine Knitting

A pre-publication glimpse of my new book, Translating between Hand and Machine Knitting.

CoverTo be published by Crowood Press in summer 2018, this book is lavishly illustrated with clear step-by-step instructions on knitting techniques, stitch structures and fabric constructions.

Unlike many other knitting books, this one explains why knit stitches behave in certain ways, and how to achieve effects using combinations of stitches. Each stitch construction is analysed and explained with diagrams and examples, for example tuck stitch (in hand knitting this is known as broiche stitch) is clearly illustrated so that the route of the yarn is tracked, and effects on vertically and horizontally adjoining stitches can be seen.  Fabrics made with this stitch in both hand and machine knitting are illustrated, explained and compared and contrasted in both methods of knitting. The most suitable method is highlighted and pros and cons of methods discussed.

diagram_stitchCopyright

The constructions of textural and colour effects are explored and described by hand and machine knitting methods. There is a whole chapter explaining how to knit a hand knitting garment pattern on a machine, or vice versa, and how to subsitute yarns between both methods. Examples and illustrations support every step, and shortcuts and hints and tips are scattered strategically throughout the text.

I am proud to say that my book has been written with the primary aim to enable the reader to take control of their knitting and create exactly what they want in both knitted textiles and knitted garment shapes.

It will take pride of place on any knitter’s book shelf, sitting next to The Knitting Book and Knit Step-by-Step.  Preorder on Amazon
