Cobra Class 18 Vs. Techsew 2700

Do you want a flat bed or a cylinder arm machine? What kind of work do you do?

I would be looking for a cylinder arm. I do a lot of motorcycle seats and thick belts and wallets.

The Cowboy 227R would work fine up to 1/4 or 3/8 inch. !/4 inch is 16 oz which is fine for a stock 227R, 3/8 inch is 24 oz and would take a little presser foot adjustment. Ditto any of the other medium duty machines. 24 oz is absolute tops for any of the medium duty machines and if I was sewing 24 oz all day I would certainly get a big stitcher like a 441 Clone such as the Cowboy CB3500 or Cowboy CB4500. The Cobra and Techsew machines would also do the job. I wouldn't get a 441 if you are sewing less than 1/4 in (16 oz) with lighter thread as they can take all the joy out of it IMO. Deal if at all possible with a dealer of leather sewing machines as these machines have to be set up for leather and should include a speed reducer and servo motor. Of late, I am finding the brush type motors easier to deal with; just one knob for speed control instead of flashing lights and buttons and Chinese directions.

Thank you for your reply, Art.

As I am completely new to sewing machines, I have never even used one for fabric, or anything in general. Would a medium duty be capable of sewing the thinner leathers with less pressure on the foot?

Is there an option for a brush vs servo motor when purchasing these machines?

Yes, you can sew thin leathers with thread down to V-46 or V-69. These are walking foot, and needle, and drop (feed dog) machines and feed just about anything in their range. I know Bob at Toledo Industrial carries this type of motor.

Most dealers will include an adjustable speed Servo motor with the machine - they make the machine much easier to use for beginners.

Let me be clearer. Servo motors can be brush type or brushless. The brush type are in my opinion better. They have better low speed torque, and have only one control or setting and that is for the maximum speed of the motor. Brushless motors also have a setting for this, but it is far more complicated than the brush type that have basically a knob for adjustment. On this forum, we often have requests for directions for setting the speed on brushless servo motors. We never have a request for setting the maximum speed on a brush type servo motor, no need, it is a simple knob, clockwise for faster, ccw for slower.
