How To Choose a Sewing Machine
By Mary Wilkins You have finally come to the conclusion that you need or want a sewing machine. Now, what is on the market and how do you make the right decision?
There are many brands of machines out there and everyone boasts different features. Some machines appeal to quilters, others want you to embroider everything including the toilet seat and the shower curtain. Searching for the right machine is going to take some time.
Shopping for a new machine can make your head spin. The girls on my boards discuss which machine is best every time someone needs a new one. We all know the name brands but I am not going to suggest one, that decision is yours. It's a personal one and an important one. I will, however give you a few basic questions you should ask yourself.
1. What type of sewing do you plan to do? 2. Where will you sew?
- sewing room 3. How will your machine be stored? 4. Consider your budget and buying habits? How long will you keep this machine? When you answer these questions, you are on your way to making the right decision. Obviously if you are going to sew from the kitchen table, you don't want a machine with lots of accessories or add-ons that will take up too much room. If you are doing repairs and alterations, you don't want a machine that duplicates the quilting stitch. If you have small children around, your machine needs to be tucked away safely. Just a few things to think about.
Research is the name of the game here. Check out the latest consumer reports. Visit the forum discussions on sew-whats-new.com and see what the girls are using. They will gladly tell you what works and what doesn't. Another source is the well known sewing magazines. Sew News and Threads do comparison studies all the time.
If you are lucky enough to have local dealers, pay them all a visit. Test drive all their machines and ask lots and lots of questions. Take fabric with you that you use and test out things like stitch length, reverse and some of the different presser feet. Find out about lessons. Lots of dealers will give you a few free lessons to get you acquainted with your machine. Above all, take your time. I cannot stress this enough. Don't let anyone rush you thru the process. Leave the kids at home so you have no distractions. While you are in the shop asking questions, you can see how the staff relate to customers and if they have the answers to all your questions. If they seem impatient or brusque, imagine how they might be after the sale. If they are not helpful now at the prospect of a sale, they probably won't be later if you need help.
On the other hand, a strong sales pitch can also steer you in the wrong direction. Paying for a top of the line model doesn't mean you are getting the machine you will be happiest with. You must resist the urge for that impulse buy. Go home and talk to someone who sews. Find out their experiences and listen to what they have to say. Again, take your time with this decision.
If you have visited all the dealers, and test driven their machines visit them all again. Visit again when you are rested and can make a clear decision. Go back and take a second look at those machines. You are looking at them with new eyes now. Maybe there are a few things you never noticed the first time that stand out now. What about that foot pedal, is it comfortable? Do you want the even feed feature? Does the machine run smoothly and quietly? Are there more programmes than you will ever use? If so, make a mental note and you can scale down your possible choices. This second visit will tell you more than you expect.
Ask about the warranty that comes with each machine. Be sure you know who is responsible for standing behind it, your dealer or the manufacturer. Are repairs made locally or will you have to pack everything up and send it away.
Be very sure you understand what is included with the sewing machine. Which feet, how many bobbins and what about a manual. The manual is very important. You will refer to the manual time after time so it should be a good reference guide to all the accessories and stitch designs along with any other functions. The manual should be full of pictures and diagrams for the basic sewing as well as clear directions. If your manual isn't helpful, do you want to go searching out the answers every time you have a problem. I wish I had a penny for every time someone has emailed me with a problem that their manual doesn't answer.
Be sure you get your sales agreement in writing and keep your copy in a safe place. Nothing less will do.
The bottom line is you must do some work before you ever sew your first stitch. If you make the effort and educate yourself, the rewards of a great sewing machine are yours.

New Torque Sensor Will Revolutionise Machine Control
By Anonymous July 8, 2004 -- Unlike traditional slip ring transducers, the RWT units make use of a simple non contact measurement technique of a radio frequency (RF) couple for power and signal communication. This means that the units are mechanically straightforward and as such they stand to completely redefine the expectations of machine builders and control engineers, who to date have had to put considerable time and expense into obtaining the accurate torque readings essential for accurate machine control and production monitoring.
They feature integral electronics with outputs for torque, speed, power and angle. The RWT 310 provides analog outputs and the RWT 320 both analog and digital outputs, which are directly compatible with PC Interfaces such as serial and USB, being user programmable for signal levels. Other innovative features include built-in peak torque sampling, storage and torque averaging, and a self-diagnostics test package. Both the RWT 310 and RWT 320 can operate from a wide range of supply voltages.
To achieve the non-contact operation that makes the Torqsense transducer range unique, SAW (Surface Acoustic Waves) devices are used as frequency dependent strain gauges to measure the change in resonant frequency caused by strain experienced in the drive shaft. This measurement is directly related to the torque experienced in the rotating machine element.
In use SAW devices are mounted onto the shaft and their output signals are transmitted by a low power radio frequency (RF) couple to an adjacent pick-up, which interprets the signals and converts them into a torque measurement read out or feeds them on into a PC for further calculation.
In a SAW sensor, the surface waves are produced by passing an alternating voltage across the terminals of two interleaved comb-shaped arrays, laid onto one end of a piezoelectric substrate. A receiving array at the other end of the transducer converts the wave into an electric signal.
The wave frequency is dependant upon the spacing of the teeth in the array and the direction of wave propagation is at right angles to the teeth. Therefore any change in its length, caused by the dynamic forces of the shaft’s rotation, alters the spacing of the teeth and hence the operating frequency. Tension in the transducer reduces the operating frequency while compression increases it.
To measure the torque in a rotating shaft, two SAW sensors are bonded to a shaft at 45deg to the axis of rotation. When the shaft is subjected to torque, a signal is produced which is transmitted to the adjacent stationary pick up via the capacitive RF couple comprising two discs, one of which rotates with the shaft, the other being static.
The frequency of the oscillation used is typically 200MHz.
The frequency-basis of the Torqsense concept gives a wide bandwidth and the susceptibility to electronic interference, common with other analogue based techniques such as inductive devices, is eliminated.
'Torqsense' using the SAW concept was developed, trade marked and patented by twins Anthony and Bryan Lonsdale, founder Directors of Sensor Technology. They have had a range of SAW-based transducers available for about five years, but these have been virtually hand-built and had the control electronics housed separately from the pick-up head.
"Our earlier models were designed to be robust and simple, both in use and for manufacture," comments Bryan. “This was essential to make it attractive to users across a wide range of industries, who were doing us the courtesy of trying out our radical new technology but who may have been put off by having delicate or complex equipment to deal with.
"With the concept now proven in the real world of factory machines and process plants and commercial laboratories, we have moved on to develop the RWT 310/320 Series, in which we have integrated the electronics and the pickup into a single unit and designed everything for serial manufacture."
The RWT 310/320 Series Torqsense will be available with full scale deflection of 1Nm to 20Nm with other sizes to follow with full scales up to 10 000Nm.
"The sequence in which we introduce the variants will depend on market demand, but we are committed to having the complete range fully available by the end of 2004."
