I have seen on this forum that some have put a thin layer of weave over the glued joint on the outside to prevent paint cracking. How many have done this? How many have seen this cracking in the paintwork after long service? Over the years I have looked at many Europas but I have never noticed this cracking in the paintwork. I intend to fill over the joint but does anyone recommend the extra protection of a thin strip of fibreglass? -------- Regards Kelv Weston Kit 497 kelv@kdweston.biz Read this topic online here: http://forums.matronics.com/viewtopic.php?p=499402#499402 ________________________________ Message 2 _____________________________________ Time: 02:28:44 AM PST US From: davidjoyce@doctors.org.uk Subject: Re: Europa-List: Door and Windscreen Glass Kelv, Not worth it IMHO. Mine has remained uncracked for 20 years.

Was advised at the time not to plasticise the clear coat, but wish I had. The 'cracks' over the glass are of no consequence and don't bother me.

Trim, fit, practice the install and properly block it to get an even bond and it lays fairly nice. A slight gap that is filled with Redux between the glass and skin rarely will leave a crack, but there will be a hump or a lot of blending for a truly fine show finish. If you leave a trough or sharp ridge, the filler may crack due to material expansion/change. The slight miss match in height is due to the newer slightly thicker glass we have now. I normally use expand cell and patience. The windscreen and doors rarely crack around the joint rim when filled up on to the glass then covered with good 2 part urethane. If the glass has no filler sometimes there is a bit of a transition hump or ridge. For only those who want a very smooth job and or have used the optional 1/4 inch windscreen: The use of 2 oz glass over the initial fill will allow a smoother finish and less of a chance of cracking of the extra filler. This same technique can be used to HELP prevent cracking at the spar and wing fillet walkway (or butt seat area) of the trigear. In the area of the leading edge between the root rib and first rib forward of the spar of the XS flexes under "butt" pressure on trigear ingress gymnastics. Glass over the filler can help. I've used carbon fiber layers and standard Rutan 7725 Bid to try to prevent this but the area near the spar will flex and a filler crack can happen. Document it to appease inspectors. Why worry about the cracks: In selling a used aircraft, the new owner and more importantly the new inspector/repairman, will question the crack and then want to grind out, inspect and fix any cracks, thereby decreasing your resale value.

I trimmed for a nice gap all around and had several dry-runs before applying the glue. Also hot glued some spacers onto the door to aid accurate location of the glass. Worked out ok. Bud I removed all the gel-coat from the door flange and also rounded the outside edge of the glass. I used a rounded lolly stick to remove the excess redux and formed a nice fillet between the outside edge of the door and the glass. The height difference between the door and glass is quite small, about 0.5mm. Looking at it with a straight edge across the from the door to glass, I am hoping the filler when applied across the join and sanded will just transition up onto the rounded edge of the glass. Fingers crossed. -------- Regards Kelv Weston Kit 497 kelv@kdweston.biz Read this topic online here: http://forums.matronics.com/viewtopic.php?p=499414#499414 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message europa-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Europa-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/europa-list Browse Digests http://www.matronics.com/digest/europa-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
