jmalcol1 Posted February 14, 2005 Share Posted February 14, 2005 One of my cycle wings has come unstuck from the bottom stay ☹️ What do I use to stick/bond it back on? Do I need to prepare the surface? How long to Bond? Should I remove the wing entirely and refix? Should I replace with Carbon if so from who?

andy_h Posted February 14, 2005 Share Posted February 14, 2005 I'm also interested in the answer. Rear of mine came off too and I used mastic. Was this a good idea? Seems to hold so far. Cheers, Andy road legal 2.0 VX race car 😬 Link to comment Share on other sites More sharing options...
paulyb Posted February 14, 2005 Share Posted February 14, 2005 Try this adhesive either on its own or to stick the 'Bighead' fasteners here to the cycle wings and then cable tie these to the wingstays - enables easy removal / re-fitting I used this on mine some time ago - solid as a rock Link to comment Share on other sites More sharing options...
jmalcol1 Posted February 14, 2005 Author Share Posted February 14, 2005 paulyb, many thanks I will give it a go. 😬 John M GK03 EGX SV Link to comment Share on other sites More sharing options...
MrD76 Posted February 15, 2005 Share Posted February 15, 2005 If you look at www.caterham7.info, I used fibre glass, its on Day 5 or 6 I think. Link to comment Share on other sites More sharing options...
Trevor Gilby Posted February 15, 2005 Share Posted February 15, 2005 Over Xmas I put new wings on mine, and basically used four bighead fasteners per wing bonded on with fibreglass resin and then overlaid with strips of fibreglass.Ensure the original surface of the wing is "keyed" to give it maximum oppertunity to bond. As to its performance the car had a severe wind hammering on sunday last for over 700 miles and the wings are still solidly bonded on. There are many topics in the archives of blatchat, which is where I found my method. Good luck Link to comment Share on other sites More sharing options...
Frying Pan Posted February 15, 2005 Share Posted February 15, 2005 I also used Bigheads and adhesive (I got a tube of windscreen adhesive). One of the bonds failed quite early on, but this was due to me being mean on adhesive on the one corner - all the others are rock solid. I used HV-350 (Demon Tweeks sell this) to repair this one. Over the winter I took both front wings off, and one of the cable ties had rubbed right through out of sight, so it might be a good idea to check and replace the ties every so often...

chrisb Posted February 15, 2005 Share Posted February 15, 2005 If you do a search on here, you will come across this stuff: Wurth Zebra MS Polymer Adhesive http://www.wurth.co.uk/catpages/UK-CD_03_1205.pdf I bought some at the beginning of Jan to stick on the new front wings. I can vouch that they are still attached after blatting into some seriously strong headwinds (100mph+) on more than one occasion. Link to comment Share on other sites More sharing options...
ROC Posted February 15, 2005 Share Posted February 15, 2005 I used Sikaflex which is still working well three years on. When I prepared mine I used a b*stard file to get to bare metal and rough the stays surface. I believe that I waited 48 hours before using the car - though that was possibly because I was building it and had no option.

Dave York Posted February 15, 2005 Share Posted February 15, 2005 I would second the Sikaflex it has worked on mine. I would remove the wing and start over to ensure a good bond. I like the idea's of bonding zip ties to allow removal. Never tried it though. Seemingly you would embed the ties in the sikaflex cover the stay with wax paper then apply wing and tape in place till dry. This would give you a good fillet to rest the wing on. Yes do switch to Carbon as its the only way to go. 😬 Link to comment Share on other sites More sharing options...
stephen grant Posted February 15, 2005 Share Posted February 15, 2005 I'd second the Wurth. I believe it's what CC's use as well. Probably best to take the whole wing off and start again. A sharp knife, some acetate and a steel guitar string were my weapons of choice. But go carefully stephen Link to comment Share on other sites More sharing options...
David M Posted February 15, 2005 Share Posted February 15, 2005 I started with Bighead fastners but didn't use the setting compound for the windscreen black stuff.... then went down to the hardware store (Mackays in Cambridge) and bought the heaviest weight adhesive they had - I think it quoted around 300kg+ (it could have even been a 1000kg) some crazy over the top figure anyway... cleaned up the wings and stays and went for it... I have not had any issues through sun, snow, wind, speed or rain..... I would suggest removing and starting again though if one has failed the rest will surely follow... David GF04RCE is built running and on the road.... every day is a Caterham day!!!! He heee!!... pictures here , I am as excited as an excited thing.....

MusCat Posted February 15, 2005 Share Posted February 15, 2005 I lost my driver’s side cycle wing at 80mph on the A41, struck the windscreen directly in front of me - made a mess of the windscreen but thankfully not my head. I was surprisingly calm about it – if I’d had an aeroscreen it would have hurt (a lot!) that's if I’d been lucky enough to still been around to notice. I mainly felt embarrassed - losing bits of your car isn’t very good form - I was in quite heavy traffic but everyone behind managed to avoid the wing before it ended up wedged on the central reservation. Following the advice on a previous tech-talk topic I stuck the new one on with Sikaflex 292 adhesive (made for gluing boats together), priming the bear metal and fibreglass surfaces with Sikaflex 206 G+P primer – not cheap the glue and primer with delivery cost nearly as much as the new wing. So far it’s been successful. Unfortunately Caterham “green” has changed over the years so the new wing doesn’t quite match the original. Also I now give my wings a tug periodically to make sure they are on solidly - don’t know if this helps but makes me feel better. Link to comment Share on other sites More sharing options...
chrisd Posted February 15, 2005 Share Posted February 15, 2005 Have just got off the phone from SIKA - they recommend Sikaflex 252 or 260 - has anyone got any particular preference, as I'm about to replace both my front wings.
