Default Tip-up Canopy Question

I'm building an RV-7 with tip-up canopy and have an issue with the WD-716 1/2" tube and the C-702 canopy skin. On each side of the canopy, the outboard 3 or 4 rivet hole locations on the WD-716 tube have a significant gap between the tube and the C-702 skin. Van's says this is "normal" and suggest filling the gap with washers before riveting. However, a couple of the locations have a gap as large as 3/8", and that is a LOT of washers. Just wonder what some of you other builders have done. Thanks.

I used washers then ended up filling in the gap with epoxy so they are hidden. The canopy on these models suck! For such a nicely engineered aircrtaft it's a shame to have this canopy that seems like an intern designed.

I placed a piece of clear packing tape as a backstop behind the gap. Mixed up flox/epoxy with pigment and made a nice filet. No spacers or washers.

I cut some small tubing segments, filled them with aluminum epoxy putty and so far they have been pretty solid (750+ hours). You could probably use something like JB Weld to hold these in place and fill them.

I think I just had the last one or two that I just couldn't make work out with any amount of massaging. I didn't even mess with trying to "fill" the gap. I just put a rivet in the empty holes in the top glair shield and moved on. It has looked fine to me for all these years.

This part produced for the RV6,A was a perfect fit, at least for the two that I have done. But when Van's upgraded to the RV7,A something changed and they have yet to correct it.... very sad.

It is a very well known problem, Please fix it.

I asked Vans, during a Q&A session at Oshkosh, if there were any plans to change the 7 tip up design similar to RV-14. The answer was “No”.
Fair enough, they need to look forward ......

As a 7 Slider builder I've cussed plenty, gave my slider decision second thoughts many times having heard how much easier the tipper is... Guess not.

Sorry to hear about the troubles. I am sure once she's flying you'll never look back.
