This is a very cost-effective way to create disposable visors for your Full-face style helmets. This is a good way to save money because these style helmets are generally at least a couple hundred dollars cheaper than the helmets with "proper visors". Most of the materials and tools you should have lying around the house (if you're reading this website you should have more than enough). It only takes about 20 minutes total. (not held responsible for any assumptions as to what it will protect you against or cuts, burns, harm you receive during the process) (ALSO, this is not tested for extreme conditions)
Step 1: Gather Your Materials
For this project you will need:
-A two litre pop bottle (no-name brands seem to spring into a roll, which could be good or bad, depending on how you look at it.)
-Some velcro, enough of both sides (hoops and hooks) to cover the outer edge of where you're applying it
-A helmet with an open space for the visor to go
-Exacto knife (deadly)
-Sharpie (or other permanent marker)
-Something big enough to hold enough water to immerse, and hold the two liter pop bottle
Step 2: Get That Unsightly and Sticky Label Off!
Get out your deadly Exacto knife and cut that hideous label off, being careful not to nick the plastic. It should look like this.
Step 3: Get Rid of That Layer of Paper Still Stuck to the Bottle
That layer still stuck to the bottle? GONE, get your container (or sink) and fill it with hot water, also, fill the pop bottle with water (so it will stay in the container) and let it sit for 5 minutes. When you take it out, dry it off, and use your fingernails to pick off the paper, it shouldn't be that hard at all. There will be a small amount of glue left where the paper was, if this bugs you, you can take the extra time with anything relatively abrasive and a gentle household cleaner (orange cleaner, hand soap) to get it all off, it really isn't that much of a problem though, these things are disposable.
Step 4: Mark Where You're Going to Cut It, Then Do It
This is just the general how tall its going to be, you should cut just after the bottle starts to curve at the top, and at the bottom just before the sections-thing starts (base), mark it with a sharpie first, then cut it out, scissors or the Exacto knife work fine.
Step 5: Cut It So That It Is One Strip
Cut it right down the middle of the glue residue, so that it ends up being on the edges on either side, so that you end up with a single sheet of plastic.
Step 6: Mark and Cut Out the Shape You Want
Hold the plastic up to your helmet, and get your sharpie ready. You'll probably want to cut it to conform to the contours of the helmet. Draw it all out, then cut it out and see how it fits, always cut on the outside of the marked line so that if you mess up, you have room to re-do it.
Step 7: Velcro!
Once you have the visor to the shape and fit you want, its time to bring in the velcro. Cut into lengths and widths to fit inconspicously on the helmet, put the "scratchy" side of the velcro on the helmet, this is so that when the visor rolls up when not in use, the scratchy parts wont damage the visor, causing it to be un-see-through-able. Be generous when applying the lengths of velcro on the helmet. Cut out the soft side of the velcro now and apply it accordingly placed on the visor. An efficient way to do this is to place the visor up to the helmet and mark where the velcro will be with a dry erase marker then place the velcro where you marked.
Step 8: YOU'RE FINISHED
You're finished! It should fit and conform to the shapes of the helmet and be very easy to see through, it works just as well, if not better than a real visor "built in" to a helmet. I use my helmet for longboarding and on my scooter (1981 Yamaha Beluga) and the visors havn't caused me any troubles so far, they do get scratched up, but I just make a new one, usually lasts a month for me.
