Been a long time since I looked at that page Terry, have to say there are some very good articles that are still very relevant today. We've had (and still have I hasten to add!)some clever folk on here! |

There is also a very good post on fitting Norman windows on the "problem page"
It's the index on the left on the home page. |

Use a mini grinder with 1mm Inox discs, do not go mad and push hard, gentle to avoid heat and melting. Any burrs can be removed with a flap disc in the same machine.
I'm with Dave on one thing though - UV stabilised polycarbonate, Lexan or similar, while more expensive than Wicke's acrylic will not craze or fog after 6 months and will not shatter with yobs and slingshots pelting with stones.
Finally living the dream!

Problem is mate , on a Norman windscreen they were grub screws in to a threaded hole in an untreated bracket. Slot head grub screw , no purchase at all . Plus they ate top grade drill bits. Plus the sealant piled in to stop the leaks as the u shaped seal had dissolved.

I've always found cutting disks tend to leave a weld behind if you're not careful, and a jigsaw leaves cracks radiating away from the cut edge.
It's worth a go to them properly if you can, all the screws came undone on my princess screen frames.

I agree with mad Harold , its a pain splitting the window frame . After a 2 man struggle drilling out the rusted grub screws etc on the drivers side we dreaded the same on the other window. Our solution was dead easy but might not win a prize at he Crick show. Simply marked out a line all round the window 20 mm in from the edge . Cut out with a small grinder using a 1 mm slitting disc. Go to b and Q or wickes and get a sheet of 3 mm perspex. Measure and cut to the full size of the old window which should be hole with a 20mm border. Put clear adhesive around the top 10 mm of the border and stick the new one on.. Same on the inside . Result 6mm double glazing, or stick a thicker bit on the outside only. At the speeds you'll be doing it will be fine and most folk don't even notice.

Replaced my front windows with 4mm perspex.Available from many online suppliers.Cut it to size with an angle grinder (don't on any account use a saw)cos it will crack.
It's a two person job to undo and fasten the frame screws,and the joining pieces in the frame nine times out of ten,will need to be drilled out.
You will need new rubber seals (try googling Seals Direct)and care is needed re-fitting the frames to the boat,because to fit the cabin front the frame has a slight twist to it. Asume your boat is a Norman 20.
Overall,I found it a sod of a job and hope the new perspex lasts as long as I own the boat.I don't look forward to doing it again! |

This is a question that has been bugging Norman owners for years and still does. As I told Gee Zee, try going onto faceache and look up Wayne Ollerenshaw, He has a wealth of knowledge and is very helpful. He has done this sort of work on his own boats successfully. |
