“Why Won’t That Hoop Fit My Machine?”, Part 2

Last week I used three embroidery hoops in different sizes as examples to demonstrate one of the most obvious reasons why every embroidery hoop will not fit onto every embroidery machine.  Each hoop I used was the same in height (360mm or 14”), but they each differed in their width. 

In my 5.3.20 blog I talked about the machine embroidery hoop size in terms of the usable area inside the hoop.  The discussion today pertains to the outside of the hoop.  Specifically how far a hoop can go to the right of the needle and not hit the side of the machine, while still maintaining the allowances needed along the three sides and the top of the inside of every hoop.  This space issue is one of the most obvious reasons why a hoop will or will not fit on a particular machine.  There are other factors, such as the size of the embroidery unit itself, but this factor of the space to the right of the needle is very clear to see and understand.  Remember, each hoop must have enough space to move so it can maintain a ¼” allowance along the bottom of the hoop and the two sides and 1 ¼” along the inside top (see the May blog for pictures and examples of this).

On each of the hoops I used for this demonstration, I marked the left side allowance so it was clear what was needed for the embroidery foot in each hoop.
Let’s start with the 360 x 200mm hoop that came with my Designer Diamond Royale (DDR). This hoop allows for the 1/4″ needed for allowance to the left of the needle…
…and does not hit the right side of the machine, so I am able to use this with my Husqvarna Viking DDR.
My Pfaff Creative Icon (CI) is a larger machine overall and can easily use the same 360 x 200mm hoop with clearance to the left of the needle…
…with a much greater amount of clearance to the right of the needle than I had with my DDR.
The next size hoop is the 360 x 260 mm hoop that came with my Pfaff CI. As you can clearly see, I can’t even get the hoop close to the foot on my DDR from the left…
…because it hits the machine to the right of the needle.
The same 360 x 260mm hoop in the Pfaff CI easily fits to the left of the needle…
…and clears the machine to the right of the needle.
Last hoop to try is the 360 x 350 mm hoop, which fits both of my machines. “Wait a minute!” you might be saying about now. How can a 360 x 350mm hoop fit on the DDR when the 360 x 260 mm could not? It can because it’s a turn table hoop. The machine only has to accommodate 175mm across at a time. I used this acrylic rod to mark the center of the hoop.
So, my DDR only has to use half the hoop (175mm) and then I turn the hoop around to stitch out the other 175mm of design.
When the 360 x 350mm hoop is stitching on the DDR, there is plenty of clearance to the right of the needle.
Using the same rod to show the middle of the 360 x 350mm hoop on the Pfaff CI…
…you can see it easily clears the machine to the right of the needle.

For each hoop, no matter what the size, realize that designs are always going to be a tad smaller. For example, designs for an 8″ x 8″ hoop will only go to 7.90″ x 7.90″. This is to allow for moving the design for precise placement on your project.

Remember, if a particular embroidery hoop is supposed to fit your machine, but your machine will not recognize it, try updating your machine from the website (at the bottom right of the Husqvarna Viking or Pfaff homepage named “Machine Updates”).  Just follow the given instructions, or have Bonny’s Sewing and Fabric install the update for you during your next machine service.  Happy Sewing!
