I have a second stock windshield that I want to shorten and tint. What have you guys used to cut them? Dremel; hacksaw blade; chainsaw if you're real careful? ???
-
Any and all of the above..... ;) It just depends on your skill level with each!
Myself I've used a fine blade in the jig saw run at slower speed to prevent the plastic from getting hot and melting back together; just be sure to apply a couple layers of painters tape to protect the plastic surface and to give yourself a layer that you can draw your lines on. You can then smooth the cut with emery cloth or sand paper. Just work slowly and apply only light forces.

I've used a vertical bandsaw once with great success and I cut my Rifle with a die grinder with a this 3" blade and it worked awesome.
Cover the the windshield with making tape make a line and go slow!

How are you guys tinting?
I was thinking of getting a roll at the auto parts store and tinting on the inside to keep the wind from ripping it off.
-
some folks have had success with the spray on tint from VHT, that is used on plastic light covers and such, but in reality as you won't be "looking thru" the shortened shield, spray paint would do the job.
As for using the film type tinting, I was going to attempt it on my C14 shield, but when you take account of the compound radii that exist, it's a gamble, as the material doesn't stretch. You can however cut strips, and overlap them carfully, and cut and peel off the overlaps while its still wet during the application.
a rifle or C10 factory shield is pretty flat with regards to compound radii....
Use plenty of water/spray (2 drops of liquid soap to a quart of water works) and work on a good table surface covered with a couple towels for keeping the work steady.
-
If its short enough that you don't need to look through it, you can spray paint the backside of the shield with black, even flat black. From the front it will look glossy.
-
Thank you for the cutting suggestions gents; as for tinting, I recall reading (on this site perhaps?) that if you soak the shield in black (blue, red, name your color) Ritz fabric dye, it will absorb and tint the shield. Was going to try this and if it doesn't work, I'm only out about $6 for everything. I **** away more than that without even thinking about it on other stuff.
-
I am interested to see how the dye works because I also would like to tint my stock screen. I cut my stock screen with a dremel tool and used an automotive door edge trim to go around the cut edge of the windshield. It still looks good after 5 + years.
-
I will make a report after it's done, hopefully this weekend. 8)

I tried using a product for blacking out tail lights. I cleaned the inside of the windscreen really well, let it dry and sprayed on the material. It came out looking like a bunch of spider webs are running through it.

Cut the shield yesterday afternoon (with Dremel - worked well) and soaked the shield in black dye diluted with hot water for better than an hour. Pretty much a complete waste of time. Maybe if the solution had more dye in it the outcome would be better, as I only added one bottle. So unless that's the answer, it really had no noticeable effect. I ended up spray painting the inside satin black. 8)

The stock windshield has some type of coating on it to keep it clear. There is a place on mine where the coating is peeled off. If I recall, it is about the size of a dime but the windshield has been wrapped up in my basement for 20 years.
I'd hate to try this on a whole shield, but if someone who cut off their shield to make it shorter could take that cut piece and try to remove some of the clearcoat or whatever it is by rubbing some acetone on it, then dyeing it to see if it takes, that may help. Another idea would be to contact someone who makes or sell acrylic to see if it can be dyed.

Hijack?? (no TSA, not that kind)
What would y'all use for 'profiling' the end of the plexi? I'm going to shape the inside upper lip of a Ceebailey 'un-NACA' duct so maybe it will flow better. I'm concerned a Dremel will grab and I'll wind up with gouges into the edge instead of a rounded leading edge.
-
I use a plastic cutting shaft with my dremel to cut holes. It looks kind of like a stretched out drill bit. Very easy to cut things with and doesn't pull on any direction. My Walmart actually had one hanging up. When done, just use a metal file to take the square edge off.
I'm hoping this is what you are asking.
Edit: The bit I purchased is metal but they called it a plastic cutting bit or something like that.

I bought a can of that stuff and threw it out - same results as you. The can sounds real good when you read it, the product suck though. I used gasoline to get most of it off. Then used 220 grit to sand the back side to give good tooth for oil-based bed liner. Do not use the water-based bed liner either. It will peel later from sun exposure.

As far as know, the C-10 winshield is not "coated" with anything. There is nothing to peel off. Yours has probably got a crack or imperfection that makes it look like it has a layer.
Most clear sheet plastics can't be dyed (at least to and significant amount). Acrylic (Plexi-glas) and Lexan are some of them. The colorant has to be added at the manufacturing process. It has to be porus for the dye to soak into it. The nylon and ABS RC car parts dye nicely with fabric dyes but this does not help our windshields. You can only spray them on the surface.

Wouldn't proper Southern plural be "What would 'all Y'all use...'"? Sorry, couldn't resist! Anyway, I used a file and a piece of 320 wet/dry sandpaper to shape, smooth and contour the lip after cutting. Both a flat file and an oval shaped one should suit you fine. ;D
