I search the archives for information on windshields but could not find what I was looking for. I’m just wondering if it is better to wrap the front with
Lexan or something similar or could I just cut three individual pieces of plexiglass and fasten them in between the braces? It doesn’t take much to weld in some fasteners to hold individual pieces. I was just wondering if anybody has done it this way.

I wrapped mine - easy job its easy to get off for maintenance
i put nutserts for the screws to go into
-
I used Lexan on mine - welded tabs to the windscreen frame for through bolts - put sides on first - then front over them - Lexan bends can be done in standard metal brake with out any problems or heating. Hope this helps
Tried to send 3 pics, then 1 pic - files too big it says - send me your email and I will send pics that may help.

Never mind the email address, it looks like the pic snuck thru somehow.

Looks great. It looks like you been the front piece over the side pieces. What did you cut it with?
-
Yes, I bent the two sides of the front piece over the side pieces to keep the wind from getting under the corners - that has worked so far. I used Lexan because it bends in a sheet metal brake without breaking (up to a point :-) that is) - It is a bit softer than plexiglass, so will scratch or haze easier than plexi, so is important to flood with water to clean - just a damp rag will cause scratches if you dont get all the grit off first when cleaning. You can buy a Plexiglass cutter at Home Depot or Lowes - but I just use my Lock Blade knife upside down to scribe the line several times where I want to 'break' the lexan or plexi - I use the tip of the top of the blade to scribe the cut line several times, place that line along the edge of the work bench, with the piece I want to keep on top of the bench and snap down along the line. Use scrap to practice a few times and you will have it down. Hint: Keeping the protective film on will help deter scratches while doing the cutting. Hope this helps

i make a of templates with lexan
we use a thin 4" cutoff wheel , or tin snips (just dont cut to end of snips) you then can sand it with flap wheel
make sure its at temp if its too cold it can crack , never had a crack when cut with grinder
I always add some 2" electrical tap to the bend line on both side as the plastic can pull away and you can get scratches
you are more likely t break it drilling a hole with a new sharp drill bit

What size sheet did you purchase?
AC Spruce has a .060 - 4' x 4' for about $30.
Does that sound about right?

Hi Hugh,
Can you tell me what the thickness was of the Lexan you used?
-
i thing i did find you must use grommets and a washer and do not do the screws up tight
the lexan with craze a little at the holes
-
Thickness of Lexan Used - What ever they had at Home Depot - I think it was 3/32 inch....

I wanted to thank you all for the input. I think I will cut out cardboard templates and then trace them and cut out the Lexan. I’ll have to put a few more fastener tabs on the windshield braces but I prefer this method instead of heating the Lexon up and bending it around the windshield brace. I looked at 060 thickness and I think that’s too thin. I think I will put on a little heavier thickness.
