| Hello chaps, how would you lot tackle the rear windows problem? I want to put it back to as it should be. Should I get a template or ask the chap with the molds to make up a bit to let in so to speak? |

To sort the rear window I would prepare the edge of the opening ready for laminating (grind and feather it back). Then wax a smooth flexible board (formica or metal sheet works well) and fix it tight down over the area you will need to cut it to follow the contour around the top of the window to stop it lifting. You can screw, weight or tape it down it doesn't matter how as long as it's tight. Then apply gel to the sheet into around 8-10" in from the edge of the current cut out. Once cured lay up 3 layers of 450g chopped strand mat over the gel and onto the body by 2" staggering each layer an extra 1" each time. This would be easier if the shell was upside-down but that depends on your plans however it's not to bad with a little patients. Once cured remove external sheet I would then grind the joint line about 2" wide and add one layer to the outside to stop a cracking forming along the joint later this can the be sanded, filled and faired with either gel or body filler (body filler will shrink more than gel). Once your happy you can mark out the shape of the original hole and cut it out.
You will need pretty much the above procedure even if I made a section for you to let in.

Hi mike, thanks for your advice!
Sorry, Did you mean fix the formica/metal sheet to the inside or the outside of the body? The rest I understood thank you! |

Outside as it will pull round to the shape nicely.

Having another look at the pictures the top half of the rear window looks to follow the stock line. The lower section appears to be roughly the right place in the middle just the rounded sides that lead into the top half have been cut square. So I think your fix will be those two corners and removing the middle bar. I would leave the centre bar in while rebuilding the corners as I think it will help with the shape though this may not be the case in reality.
I love the suicide door conversion that wouldn't make it scary to drive at all.

Hello,
could anyone possibly do me a MASSIVE favour and make me a rear glass template out of paper which could be then posted to me so I can sort out correcting the rear window aperture on my shell. As I'm struggling to sort it without one.
Cheers Chris |

| Hi Chris, Where are you? I have an old (knackered) rear plastic screen that may be of use to you for this job. I'm in Norwich. |

Hi Chris, email me your address and I'll get it out & send it.
FYI it's no good for anything else as it's 40 years old and I've drilled a few holes in it when I was rejigging the rear screen hole in my Jem. It had become warped and I had to get it flat again so it would fit the new screen. |

Failing that I can template the rear hatch mould but an old screen is probably better for what you want.

I have made a hardboard template for the Jem rear hatch, with the intention of getting some made in Lexan (polycarbonate). They won't be cheap but will be much lighter than glass. If you are interested please email me. I can add more to the order if needed.
I would advise not using laminated glass. It is very heavy and is inclined to crack if you let the rear hatch drop on its prop, so if you are using glass get toughened. |
