Protecting Plexiglass

When I was pealing off the protective layer of plastic on new Plexiglas I got the idea of making tear offs. Sprayed distilled water on plexi, wiped off most of it, then used clear plastic wrap. It's going to take some practice to get it right, but I think it will be an easy to remove and not scratch up the plexi. Also learned not to attempted putting the clear plastic wrap on outside in the wind. The last sheet on the left went on without many air bubbles and wrinkles.

Saw it first on motor cross dirt bikes years ago. I think it will work better once I learn how to apply it. I have Plexiglas on other terramite and it's all scratched up. The view is much better on new plexi with tear offs. This will extend the life of this window.

Simple and CHEAP idea.

There's a place near me called general rubber that carries a lot of it. I use it in control panels to make them arc flash compliant.
 
Parsimony, extreme unwillingness to spend money.
I spent $60 on the thick plexi. How is that parsimony???? I could have saved about half if I had gotten the thinner plexi.
 
Lexan man. Lexan.
It's WAY better than plexiglass - doesn't scratch, doesn't yellow or turn cloudy, is Much tougher than plexi, doesn't shatter after being exposed to UV. And... you can SEE out of it for a long time.
But it's your machine and your business George. I just hope you don't drive over any pretty flowers with it cause you can't see out of your window.
 
Did you price out plain auto glass? Not shatterproof windshield but the stuff for frugal farmers (Herculite.) Side glass in cars. Flat is pretty reasonable.
 
I can see just fine. It's not as bad as it looks. Plexi will last longer than I will. Tractor is kept inside pole barn, so not worried about the UV and yellowing. The Plexi on my first terramite was a used piece with scratches. I put it on 9 years ago and it hasn't yellowed. It's kept inside too.

I don't drive over flowers or I'll never hear the end of it.

I backed over a small ceder tree 3 different times. Snapped off the top half of tree. It's surprising just how well it looks now. One of the best ones in the gravel pit.
 
I thought for a second> Ole' Geo needs to keep better company.. I thought that windshield was smashed.. lol
Harbor Frt, sell "thicker" tear-offs for their sandblaster.. just a thought..
Honestly tho, HOW MUCH protection are you gonna get from "Saran Wrap".??

I played the Plexi-glass vs Lexan game ONCE..
One of my houses backed up against an elementary/middle school playground..
& the little bas..... liked to throw rocks after school..
The plexi got damaged quite often & had to be replaced.. AFTER repeated hits on the Lexan.. I just laughed & found their parents..
NOW THAT was funny.. Mom & Dad BEAT THOSE KIDS W/ A BELT IN MY BACK YARD.. & I MEAN B-E-A-T..
 
My goal is to peal off the dirt instead of washing it off. Stuck on clay is a witch to remove.

I'm happy and that's all that counts don't you-alls think?
 
George only gets an honorable mention for cheapness in this category. Below is a backhoe I bought from a trailer court. Instead of buying a piece of plexiglass they just used an old window frame and plywood that happened to be sitting around.

> Spending $60 on plexiglass that will scratch up rather than spending $71 on lexan that will not scratch.

Lexan is nearly unbreakable, but scratch resistant it ain't. And it's pretty much impossible to remove scratches from Lexan.

For something that might have to stop a rock, polycarbonate is by far the better choice. But for abrasion resistance, acrylic is generally better and is easier to restore when it is scratched.
 
Mark,
I don't know what all the flap about Plexiglass. No way am I going to get hit with a baseball. I put it on to keep crap from hitting me and it works just fine on my other tractor for years. Used it yesterday when doing my annual pruning. The plexi is double strength, twice the thickness of regular glass, almost a 1/4 thick.

I'm with you, George-san. Airplanes flying over 200 knots have used Plexiglas windshields for decades. Why? Partly because acrylic is easier to form than polycarbonate, but also because it has superior scratch resistance and because scratched acrylic windshields can be easily repaired. Sure, if you hit a sandhill crane going 200 knots, it's going to come through the windshield, but the risk of that is considered acceptable compared to having a windshield made of a material that can't be maintained.
 
The story was that there was an older maintenance guy at the park who
would drive around on the backhoe instead of the usual pickup truck.
Nothing wrong with customizing your ride! Below is a picture from the
Craigslist ad of the backhoe at it's former home.

If you look closely, the plexi is curved at the top to conform to the roll cage. I would hate to think how much a special curved glass would cost.
