				Hi everyone.  I'm ready to attach the windows in my RV-10 and am looking for advice on those who have used the Lord 7545 A/E adhesive sold by Geoff at Aerosport Products.  After reading lots of positive comments from here about it, I obtained a few tubes from him.
 
 The plans call for installing the windows onto the doors when the doors are off and laying flat, presumably to allow gravity to help hold them in place while they are being cured.  Of course, the rear windows can't be installed with that luxury, but they're smaller and lighter.  And the windscreen rests largely on the nose while curing, so that should be less of an issue too.
 
 But my question is, considering that Lord Adhesive is different than Vans' would have us use anyway, is it sticky enough that I could install the windows on the doors while the doors are closed and on the plane - in essentially the same orientation as the rear windows?  The reason I ask isn't due to laziness    But instead, I'm one of the lucky ones whose doors ended up fitting quite well without a lot of work.  And I figure that if the windows are attached to the doors while the doors are in their proper latched position, they can only help (slightly) to further stiffen the door in the proper position.  The last thing I want to do is to fit the windows to the doors when the doors are on the floor, and then find that gravity warped things slightly while they were curing, and the doors no longer fit properly.  It would seem to me that adhering the windows to the doors when the doors are in their closed position will help keep everything aligned properly, so long as the Lord adhesive is sticky enough before fully cured that it will hold the window tightly to the door and in place while it is curing.
 
 Thanks!

				The short answer is no.   You need minimal pressure to hold the windows in place.  If gravity causes any movement at all, you're going to have a major headache on your hands to resolve.  I did my doors laying flat.   On the rear windows I made fingers out of scrap aluminum to hold the pieces in place that were cleco'd to the cabin cover.   You could do the same on the doors.  The angle of the bend determines how much pressure is applied.    You don't need much, just enough to keep things from moving.

				If you're not worried about looks, then let the cracks develop. It's not a window separation issue, just a dissimilar material issue.

				I used the 7545 and clecoed through the window (made a 'plastic drill 
 bit,) into the flange instead of making clips.  I did all the 
 windows/doors attached to the airplane .... a lot easier than chasing 
 the door across the bench.  I ground a 'valley' around the window and 
 laid fiberglass tape across the edge of the window.  Filled with 
 microbaloons and sanded.  Unfortunately, I didn't crawl into the fuse to 
 trim the excess 7545.  You need to do this!  That stuff is terribly 
 hard. I'm still building so don't have any operational issues ......

				I used Lords adhesive and then glassed over the seams.    It's been almost two years since painting and no cracks yet.   
 
 I know that didn't answer your question, but it may help the OP.

				Can a layer of cloth be placed over the window/cabin top joint to hide the crack, or will the crack develop regardless?
 
 I note that the Cirrus SR-20 has a thin bead of flexible sealant in the gap between the window and cabin top.
 
 Enquiring minds need to know please as I'm up to this step too.
 
 Warm regards

				Attached photo shows the "not too tight" straps and insulating foam blocks
 to attached the rear windows.  After gluing I filled in the seam with micro
 balloons, sanded flush, then two bids of medium weight glass over the seam,
 then more micro over the fiberglass to fair in (second photo).  No paint
 cracks after three years.
 
 I also used Hysol for the adhesive as it had a good record with the Lancair
 crowd:

 4918-BB0C-79343CDB7869}
 It worked, but I suspect the other options work just as well.

				I did not use the Lord adhesive as I copied Dave Saylor's method using
 Silpruf instead.  Silpruf almost has a proseal consistency so it might be
 less viscous which lends itself to this process a bit better maybe?  
 
 I glued the door windows in while attached to the plane.  I used several tie
 down straps and blocking to apply even, light pressure to the windows as
 well as duct tape to keep them from moving.  I did this for both the door
 window transparencies and the fuselage ones.  I think they came out ok but
 the only air time my project has seen is dust falling on it in the garage so
 YMMV.
 
 See pictures.

				Since my RV-10 seems to be the poster child for bad decisions made with
 respect to window adhesives, I'll update the story.  I used a composite
 adhesive back in 2007  (no longer on the market) that Glasair builders were
 asserting was much better than Weld-on 10. In 2011 at about 450 flight
 hours, I had a rear window blow out in high, cold conditions (15K feet, -12
 C outside, inside heaters blasting).  It was a big surprise and caused a lot
 of noise in the back seat and some turbulent air in the cockpit:
 http://faculty.washington.edu/dmasys/RV10/RV10_lostwind_rearview.jpg
 
 I replaced the rear window using Weld-on 10 as recommended by Vans.
 
 Fast forward to 2014, with 750 flight hours.  Climbing through 12K feet to
 get over buildups near Eugene, OR, the entire pilot side door window
 shattered and departed the plane.  Most of the window fragments hit the VS
 and HS, making a variety of dents in the leading edges.  But some of them
 came in the cockpit at high velocity.  Luckily I had the Rosen visor swung
 to the left, providing an extra layer of protection.  A window fragment
 shattered the Rosen visor; I got a small neck lump from the impact, but
 nothing drew blood.  So we continued on and made it back to base.
 (Performance observation:  an RV-10 that does 170kts with all of its windows
 intact will still do 150kts at same power setting with the pilot side door
 window absent, but it is awfully windy inside).
 
 Suffice it to say, I removed and reattached the remaining windows with
 Weld-on 10.
 
 Moral of the story:  make sure you have a compelling justification for
 deviating from Van's directions on mounting the RV-10 windows.

 Subject: Lord adhesive window installation question
 From: Dan Charrois <dan(at)syz.com>
 Hi everyone.  I'm ready to attach the windows in my RV-10 and am looking for
 advice
 on those who have used the Lord 7545 A/E adhesive sold by Geoff at Aerosport
 Products.  After reading lots of positive comments from here about it, I
 obtained
 a few tubes from him.
 
 The plans call for installing the windows onto the doors when the doors are
 off
 and laying flat, presumably to allow gravity to help hold them in place
 while
 they are being cured.  Of course, the rear windows can't be installed with
 that
 luxury, but they're smaller and lighter.  And the windscreen rests largely
 on the nose while curing, so that should be less of an issue too.
 
 But my question is, considering that Lord Adhesive is different than Vans'
 would
 have us use anyway, is it sticky enough that I could install the windows on
 the doors while the doors are closed and on the plane - in essentially the
 same
 orientation as the rear windows?  The reason I ask isn't due to laziness  
 But instead, I'm one of the lucky ones whose doors ended up fitting quite
 well
 without a lot of work.  And I figure that if the windows are attached to the
 doors while the doors are in their proper latched position, they can only
 help
 (slightly) to further stiffen the door in the proper position.  The last
 thing
 I want to do is to fit the windows to the doors when the doors are on the
 floor, and then find that gravity warped things slightly while they were
 curing,
 and the doors no longer fit properly.  It would seem to me that adhering the
 windows to the doors when the doors are in their closed position will help
 keep
 everything aligned properly, so long as the Lord adhesive is sticky enough
 before fully cured that it will hold the window tightly to the door and in
 place
 while it is curing.
 
 Thanks!

  Since my RV-10 seems to be the poster child for bad decisions made with
  respect to window adhesives, I'll update the story.  I used a composite
  adhesive back in 2007  (no longer on the market) that Glasair builders were
  asserting was much better than Weld-on 10. In 2011 at about 450 flight
  hours, I had a rear window blow out in high, cold conditions (15K feet, -12
  C outside, inside heaters blasting).  It was a big surprise and caused a lot
  of noise in the back seat and some turbulent air in the cockpit:
  http://faculty.washington.edu/dmasys/RV10/RV10_lostwind_rearview.jpg
  
  I replaced the rear window using Weld-on 10 as recommended by Vans.
  
  Fast forward to 2014, with 750 flight hours.  Climbing through 12K feet to
  get over buildups near Eugene, OR, the entire pilot side door window
  shattered and departed the plane.  Most of the window fragments hit the VS
  and HS, making a variety of dents in the leading edges.  But some of them
  came in the cockpit at high velocity.  Luckily I had the Rosen visor swung
  to the left, providing an extra layer of protection.  A window fragment
  shattered the Rosen visor; I got a small neck lump from the impact, but
  nothing drew blood.  So we continued on and made it back to base.

				Thanks, everyone, for the great response.
 
 I never even thought of using aluminum "fingers" like that (or straps and foam blocks as others have done).  That's a great idea, and so simple too and straightforward too!  I guess that even after getting this far with fibreglass, I still don't automatically realize that it's OK to drill holes where you don't want them permanently!
 
 I'm definitely going to try this idea, and with the doors on and shut for good measure too instead of on the bench (can't hurt!).
 
 Thanks again!
 
 Dan

  The short answer is no.   You need minimal pressure to hold the windows in place.  If gravity causes any movement at all, you're going to have a major headache on your hands to resolve.  I did my doors laying flat.   On the rear windows I made fingers out of scrap aluminum to hold the pieces in place that were cleco'd to the cabin cover.   You could do the same on the doors.  The angle of the bend determines how much pressure is applied.    You don't need much, just enough to keep things from moving.
