Ron,
Sounds like you are describing installation of the rib in the HS tips. After trying styrofoam and fiberglass (which absolutely doesn't work - the styrofoam melts - my first experience with fiberglass), I ended up fabricating a piece of 0.032 Al to fit this and epoxying it in place, then filling around the edges.

Louise can chime in, but she just used the pink foam from Home Depot yesterday to do bulkheads in the empennage tips, and it worked fine with the West Systems Epoxy. (I have had white styrofoam melt away with Epoxy - maybe htat's what you tried Greg?)

Yep, white styrofoam melts and makes a serious mess when used with epoxy!

I just went through this on my -9A. I used aluminum plugs and micro and they came out pretty nice.
Photos and writeup are on my web pages. |

I had some blue 1/2" foam which I trimmed and epoxied in place, filling in the gaps with micro. I then covered with fiberglass cloth bonded with epoxy, trimming along the ege. A few coats of micro and some sanding made a very smooth surface.

I want to say thanks to Bruce,Jeff,Greg,Louise,Paul,Rick and Roy Thoma. These were the two Ideas (metal plate and foam ) backed up by using epoxy and micro and cloth to get a nice blend in either of the end pieces. I'am on my way to order the list of items by Roy. Sounds like Aircraft spruce is the first item of the WEST SYSTEMS material.
Thanks for all your help.

West Systems is also sold at WEST MARINE in Portland. I love being able to pick up all my WEST SYSTEM stuff without worrying the box will be sticky when it arrives.

Thanks Jason, I maybe up in Portland later this week after all. My friend Roy said to get 105 level and it looked good on his 7A. Is that what you used? Ron
