1. The nature of the zigzag stitch allows the thread to stretch with the fabric. Turn the hem up the desired amount, then use a zigzag stitch to secure it. A narrow zigzag stitch is less noticeable.Again, this stitch is most successful if you stabilize the fabric and use a walking foot..

Because the leathers will resist pulling back up, it is recommended that you not use PVC pipe for drop pipe. This 2 packer is used in a 2 well to pump from depths deeper than a shallow well ejector can pump from.When using a 2 packer with a VS vertical jet pump, use 1-1/4 drop pipe to allow as much flow as possible so as to not starve the jet pump.ecause the leathers will resist pulling back up, it is recommended that you not use PVC pipe for drop pipe. This 2 packer is used in a 2 well to pump from depths deeper than a shallow well ejector can pump from.
Explanation. Piezo injectors use piezoelectric technology to open and close fuel injectors at extremely high speeds and precision to inject fuel into an internal combustion engine. These injectors are used in both petrol and diesel engines to improve their persformance and efficiency.iezo injectors have the ability to inject fuel into the cylinder several times in one stroke (as many as seven times). This is very useful in a diesel engine where a spark is not used to ignite the fuel. Multiple injections allow a pre, main and post explosion and ensures no fuel is wasted.
