Now I might as well give some detail in case anybody would like to make their own. If nothing else, because I wish someone would have posted something like this online for me to copy when I was thinking about making this. It's pretty weird that so many people have asked how to carry a pizza on a motorcycle, but no one seems have posted a half decent solution to do so. At least not for sportbikes.
If you want to do this your going to need:
- Pizza Bag
- 5mm board
- 2x Adjustable 48" Bungee Cords
- Jigsaw or any other suitable saw
- Seam ripper
- Sewing Machine (Optional but highly suggested)
- 1" Strap (webbing)
- 1" Buckle
- Black, Silver, Red Thread
- Needle for handsewing
- Sealer (Optional)
- Router with rounding bit (Optional)
Anyways, here we go.
The first step is to buy the bag. The bag I used is the New Star 50110 Insulated Pizza Delivery Bag, 22 by 22 by 5-Inch, Red
. Even in hindsight it looks like the best bag for the money (19$ shipped) mostly because of the reflective interior which keeps the pizza hot without adding weight or bulk. If you see another bag you like more, or in another color or size, it should serve just about the same. I doubt there is a big difference between most bags. None of the cheap bags seem to be rigid on their own, or have insulation on the sides or the flap. All of them seem to have insulation on the top and bottom (including this one), vents, are mostly water resistant, and that's about it.
The next step is to buy some wood to make the base. I used this: Underlayment (Common: 5.0 mm x 2 ft. x 4 ft.; Actual: 0.189 in. x 23.75 in. x 47.75 in.)
. For 5.99$ it's extremly lightweight and pretty rigid. For the price it's perfect. And it's probably more than twice as big as you need if you make any mistakes.
Measure your bag and cut to size. If anything oversize it and trim as necessary. Snip off a bit from the corners so they don't poke through the bags material (look at the corners in the picture). I personally used a router to round off the edge that would face down in the bag so it wouldn't damage the bag with the sharp 90 degree edge, or at least so the board would be less noticeable. It was worth the extra effort, but if you don't have access to a router it probably isn't necessary.
Finally, I applied a sealer to the would since I imagine it might eventually get wet if I clean the bag, or take on odors or whatever. Probably not necessary either but for 5$ you can do it and have extra for any other project.
I only took a bad pic of this step since at this point I had no idea if the project would actually turn out. Here you can see the board after cutting with the sealer drying.
While I was deciding what the hell I was gonna do, I removed the ugly "Food..." something or other badge the bag came with (it doesn't appear in the item listing) and put some velcro so I could put on a USA flag badge I had laying around, or whatever else I felt like. Nothing like patriotism, motorcyles and pizza.
Next step, put some thread in the sewing machine. Draw a straight line with chalk or a pencil a centimeter or so in front of the bottom foam. This is so the foam or board doesn't move forward into the flap during use. It's easier and looks better with a sewing machine, but it can be done by hand if needed. Just sew a straight stitch with thread matching the color of your bag. If using a sewing machine, use a smaller needle (70 or so, to not damage the material) with different top and bottom thread to match the color of each side of the bag. Use a longer stitch length (3-4mm) so you don't weaken the material. That way the stitch is virtually unnoticeable. You might need a roller foot if the the material sticks to the regular foot.
Now you have to get into the ugly part. Rip open the bottom-rear seam. There are two different stitches your going to have to open. Do it without damaging the material since you'll be using the same holes later on.
After that, install the board. If you rounded off the edges, insert the board with the rounded side edges down. Then seal the bottom side of the bag up again. It's best to do this by hand using the same holes the original stitches went through to not further damage the material.
Now you have to reattach the black "edge" of the bag. With a sewing machine, managing the rigid, large bag can be a pain but it isn't too hard to do. You can also do it by hand if necessary or if you want.
Now the bag stays rigid on it's own. That's pretty much the most important step, and the main feature needed to be able to use it on the rear seat of a sport bike with very little surface holding it in place.
I wish I could say the worst is over, but adding the loops was the largest pain in the ass for me since you're sewing through 3 or 4 layers of the bag's material, plus 4 or so layers of webbing if I remember right. It's pain doing it by hand, and on a consumer sewing machine it jams every few tries. How easy or hard this is depends more on you and how you're doing it.
Basically you have to rip the seems on the bottom side of the bag where the carry straps are. You only have to rip enough to "tuck" in the webbing on both the top and bottom to make the loops you can see in the pictures. Then just sew it up again, and reinforce it well (I did two rows of stitches) so the previous stitch you cut doesn't come loose, and so the elastic cords pulling on the bag doesn't damage the loop or the bag. It doesn't have to look pretty since it's a pain to sew this part, but it can be done more or less quickly.
Since I can't add more images, I'll continue in the following message.
