It has been almost ten years since the last post into this topic. Anyhow, I will tell what I know of my last purchase, a Brother industrial sewing machine type named here. Most of you are pros compared to me, here you may find nothing new at all - I am happy to read your comments. This particular sewing machine is for high speed sewing of clothes, thin and semi-thick garment materials. Really high speed - I was told by a sewing machine technician that even 8000 ( eight thousand!) stitches per minute was done in a clothes factory. This is approximately 1,5 miles a hour! I was also told, that with that speed some of the machine parts got so hot, that polyester thread started to melt, which was the limiting factor in the production. In comparison, home sewing machines do up to one thousand stitches per minute at their best. Mine has a 550W motor and a clutch. I also learned there is not very much information on this particular db2-714-3, especially what comes to hobby or repair shop use. I list here some advantages what I found using it or reading in the internet: + It makes uniform length and tension stitches regardless of the garment type; silk, cotton sheets, jeans, furniture upholstery*, bags and sturdy canvas. + The variety of thread thicknesses is from "hair thin" to sturdy "bear thread", all mechanisms are precision made and the extremely bulky body - you adjust the thread tension once and my machine really keeps it right. + It does only straight stitch. You want to sew thousand bed sheets, this is the machine! + The capability to sew through thick layers of garment material, pocket corners of jeans for example is convincing; the machine does not even change sound when it runs over thick seams or similar spots, where a domestic machine will stop and start wheezing like a fly caught in a spider's web. Now to the question, is this the machine for my man cave? Can I fix all the strong stuff what cars, boats, belts and outdoor stuff is made of? I would say ... well, yes ... well... if you have the following in your mind; (Please note; the foot I write about here in my text is the little foot next to the stitching needle NOT the foot pedal you operate with your leg) - This machine is for garment, clothes material, it does not have a walking foot feeder pinching the material during a stitch, all material feeding is done by the feeder underneath the garment. - Which means, your car upholstery often has 3-6 layers; support garment, then "sponge", then support for the top layer, top layer garment=the visible upholstery, and double garment edge tape filled with a round nylon "or electric wire". A sewing machine like this with underside feeder only, without a walking foot on the top of the material layers, is a way less suitable to do the job keeping all the layers on their place while sewing. - This applies also to waterproof hood and vinyl materials, you can find a suitable needle and thread for the job, the machine may do the stitch, but feeding the material will not happen or be constant without a walking foot. - You can not add a walking foot feeder to a machine which is not intended for it. A separate actuating shaft and levers operate a walking foot. This model does not have them, this is not a slow, high torque rock crawler, this is a super saloon speedster. - there are roller/wheel type foot for sewing machines, I have no idea if they are available for this Brother machine? - The speed is way too much if you do not slow it down. Original pedal and motor are way too much for me! What you need is like 2 stitches a second when repairing a backpack or sewing a belt etc. The machine will be happy to run 50-100 stitches per second and your belt will disappear behind the table before you even noticed what happened. How to slow down this beast? This particular model is not made for slow sewing with high needle punching loads, there are models designed for heavy leather and similar work. There are many videos on YouTube how to reduce the speed of an Industrial Sewing machine. Look for these topics; 1. Adjusting the speed pedal of an industrial sewing machine 2. Clutch motor or servo motor for industrial sewing machine 3. Changing the pulley of an industrial sewing machine
