How I changed the height of the foot on the Handi Quilter Sweeet Sixteen Sit Down Model

I used to have a problem quilting a thick quilt sandwich since the foot was so close to the tabletop.  I recently purchased an open toe quilting foot and after changing the foot I now realize how easy it would be to raise or lower the height of the foot as needed. 
Here is a diagram of the parts I used.

Here are the instructions...
1.  First I removed the needle and the needle plate.
2.  While lifting up on the spring loaded presser bar I loosened the jam nut and screwed the hopping foot up or down depending on if I wanted it higher or lower.  
3.  Once I had it where I wanted I used an 8mm wrench to tighten the jam nut.
4.  Finally, I replaced the needle and the needleplate and Voila it was done!

Machine Quilting on the Handi Quilter Sweet Sixteen: Some interesting facts...

I've been quilting on my Handi Qtuilter Sweet Sixteen. Some things I have found...

1. It would be nice if the machine had a warning beep that the bobbin is finishing. As it is now it will sometimes make a loud clanking noise coming from the bobbin area when it get to the end of the bobbin thread.  I used to think something was really wrong but soon came to realize my bobbin had ended but not before the final stitches were pulled and tugged at the last thread ended.  Having a warning beep would cause me to stop before the ending thread bunches up.
2. I keep the lint brush in the cubicle next to the bobbin so that it is always handy for me to clean out the bobbin area each time I change the bobbin. 
3. Every time I insert another bobbin I check the tension by lifting the bobbin out of the palm of my hand (pg. 14 in the manual).  It seems as though each bobbin is not wound exactly the same so each bobbin may need a slight adjustment.  In addition I practice on a scrap before starting again on my quilt.
4. I purchased an open toe foot for my Handi Quilter.  It was so easy to change!  
5. I purchased the Supreme Slider but sometimes I don't need it since the tabletop of the Handi Quilter is so smooth.
6. Always practice your quilting design before doing the actual quilting on your project.
7. Pin baste your quilt on the side you will be quilting from that way they are easy to remove as you quilt.  I prefer to machine quilt from the side of the that has less of a pattern/design.
