CV 21 WINDSHIELD AND FRAME
« on: January 31, 2023, 03:14:50 PM »
I'm looking to refresh an old topic:  where to get a CV21 windshield and upper windshield frame.  Just bought a 1973 with a "shortie" windshield.  Ugh.  Is UPD Plastics still the best place for the plexi?  And some have recommended American Runabouts for the frame, but aren't they in Germany? Even if they could make it, how do you get it to the US undamaged?  As an alternative, I'm an automotive engineer, so I could probably make a form to bend the overall shape, but still need a length of the raw extrusion....I would go about anywhere in the US to pick it up.  And is it one piece from back to front to back?

Any input appreciated, or if you have a CV21 not too far from Detroit that I could take measurements from, that would be great too!

(PS - Disregard the tarp support)

Windshield would be easy ..  Look here for options ..  http://forum.cgoamn.com/index.php?topic=2901.0

Windshield frame might not be so easy ..  Taylor Made was original supplier.
If you can find a cross section of original frame, you could find extrusions and make your own frame.

There might be other members with CV21's .. but can't remember off hand .
Gil has a CV21 and might be able to help with measurements.

I have a spare windshield and frame for a 75 cv-18? might be something you could use to make a new one on for a 21.  The 75 has a full length frame that, I think could be cut down to fit he 21..

That's a super nice offer, NES.  But when I look at the windshield dimension tables, the CV21 windshield is 3" longer than the CV18 so the bends at the upper corners of the windshield are going to be in the wrong place, and probably about impossible to straighten and then re-bend.  I'd probably have greater success with bending a fresh piece.

Maybe I'll try Taylor Made, thanks Hyperacme.

When I look more closely at your CV18, NES, I can see that your upper frame has two different sections with a joint at the upper windshield corners.  The CV21 keeps the same section all the way around because it has to frame the top of the windshield and the two small quarter window pieces at the rear.  What I can't tell from any photographs, yet, is if it is one piece all the way around or has a joint, maybe at the centerline of the boat?

I can also tell that the grab handle integrated into the windshield frame in the rear seat area is going to be a problem finding......maybe I can at least get close.

Good to know carlsoncvx18.....I will keep that in mind if I have to go the DIY route.
It will be a few months before I can make a good assessment of how well the gel coat and interior will restore before investing in some of the big missing or incorrect pieces (windshield and frame, engine).
