Nick Jones Posted April 13, 2017 Report Share Posted April 13, 2017 Not TR in fact but closely related Spitfire IV. The car has been all the way to bits for a full restoration as is in the final stages of going back together. We are trying to refit the original screen but with a new screen rubber as the original was completely shot. We've now had the screen in the car 3 times using two different rubbers and two different fitting methods. It's a really big struggle to get it in and once it is in, it doesn't sit right. It is as if the screen is too wide for the car and the rubber lip sits up and away from the glass up both sides and especially in the corners. Only in the central 75% of the top and bottom does it sit down against the glass as it should. The screen surround has had work but I'm pretty confident that it remains the correct shape and it matches well with the spare screen surround and also Mk3 GT6 we have to hand. The screen is the original Triplex marked one and seems to be exactly the same size as the two others we have here. Prime suspect is the new seal. I've fitted a few screens over the years, the last to my 2.5 PI about 4 years ago, and I'm pretty sure they usually need a little stretching to get them onto the screen. The first one of these we had was very slack and the second is even longer making it positively baggy, I suspect that this means there is just too much volume of rubber to go in the available space. We've just modified one of the new seals so it's a snug fit (not actually stretched) around the screen. This meant removing 65mm of seal. When the glue is fully cured we'll try it again. However, this cutting has also given the chance to compare the cross sections of old and new seal. While similar, they are not the same. Below pic shows the differences and these could also be significant. Suppliers claims he's had no issues with the (many) seals of this type supplied. Any ideas? Any good supplier experiences?

TR 2100 Posted April 13, 2017 Report Share Posted April 13, 2017 I have used Moss seals OK. Stuart. Nick - I suspect you will know that If Stuart says the Moss seals are OK - then the Moss seals are OK - and the problem must lie elsewhere. A very difficult/frustrating problem.

stuart Posted April 13, 2017 Report Share Posted April 13, 2017 They are a bit of a struggle to fit as they are slightly larger section not length, this negates the problem found in the past where the rubber doesnt go out far enough round the frame to seal properly.

TR NIALL Posted April 13, 2017 Report Share Posted April 13, 2017 Nick,have you tried putting the Finisher into the Rubber first sometimes this helps it's also a Bitch to get in after fitting the Screen. Quote Link to post Share on other sites

Nick Jones Posted April 13, 2017 Author Report Share Posted April 13, 2017 I didn't get them from Moss....... They could be the same as Moss ones, but I have no way of knowing. I suppose my main question is whether that much "surplus" length would be considered normal? If we sit the screen in the frame without the seal the glass barely overlaps the flanges top and bottom but nearly fills the frame with-wise. I thought this might be the problem but our other frame and GT6 tub are exactly the same. Nick Quote Link to post Share on other sites

BlueTR3A-5EKT Posted April 14, 2017 Report Share Posted April 14, 2017 As an aside...are not TR4-5-6 and GT6 mk1 and mk2 the same screen seal. but GT6 mk 3/Spit 1500 different. Peter W Quote Link to post Share on other sites

Nick Jones Posted April 14, 2017 Author Report Share Posted April 14, 2017 Fitted the screen again with the shortened seal this afternoon. Certainly went in more easily. Shortening the screen has had a positive effect - the seal now sits more or less right round 3 sides, but one side, the second side we got in is still as before. Going to leave it a few days (in the sun where possible!) and see if it settles. Nick Quote Link to post Share on other sites
Nick Jones Posted April 30, 2017 Author Report Share Posted April 30, 2017 Answer to the screen problem.....Buy a proper screen rubber from a proper windscreen rubber supplier!COH Baines Ltdhttps://www.coh-baines.co.uk/p.....screen-surround.htmlThe others will be returned for credit with the suggestion that they stock Baines products that are fit for purpose in the future Nick Quote Link to post Share on other sites
JohnRoberts Posted May 1, 2017 Report Share Posted May 1, 2017 (edited) Hi Nick I have fitted a new screen just this year, Seal and Screen from Moss. On the advice from the guys at Moss I put the locking strip into the rubber before fitting. This was after cracking my first screen fitting the locking strip the Elin Yakov method i.e. With a mallet Best Regards JohnR Edited May 1, 2017 by JohnRoberts Quote Link to post Share on other sites
