I started to suggest that prop 8.8 bolts are available at Advanced Auto...but...I was still suffering from reinforcing tape fatigue... 
Now if you really want to talk about aircraft quality materials...check the burlap at TSC...mighty good stuff... make take a lot of poly brush however..big iron...
I think we are only discussing the reinforcing tape.. and I knew that it was very similar stuff.. and plenty safe...especially since Mike was planning to use it on the bottom of the wing..
changing anything on a kit airplane requires common sense... my neighbors tell me that I have none ...for if God had wanted--------------!!

I agree with Herb on the function of the reinforcing tape and the wing fabric. Not only does the covering make a sail, but it reinforces the entire wing structure.
Homer is still designing and building airplanes. Doubt very seriously he is shopping for parts from Wal-Marts.
Back when he designed and built his first aircraft, a hang glider made of conduit, plastic covering, and tape, nothing on that aircraft was aviation quality. All that changed when he started designing airplanes to kit.
One of the primary reasons I bought a Kolb Ultrastar for my first civilian aircraft was the fact that most of the little airplane was aviation quality, all the parts that were critical to safe flight. Very few parts on that 1984 Ultrastar were not aircraft grade hardware. Certainly, all covering materials were Stitts, and it remained that way right through a kit you buy from TNK today.
Steve Whitman was a real aviation pioneer, air racer, designer, builder, pilot, right up into his 90's. He paid the ultimate price, along with his wife, because he did not follow prescribed procedure for covering the aircraft he and his wife were flying on a return trip from Sun and Fun, Lakeland, Florida. Somewhere over Tennessee the Whitman came apart in the air.
Take care,

Its main function imho is to reinforce the cloth under the rivet head and its length adds some linear strength to the cloth over the rib... helps the cloth to lay down and not balloon between rivets...on the top side...mainly.. over time this mild ballooning over the ribs and in between the rivets could fatigue either the fabric or the rib ...
I bet Homer would have shopped in the aviation dept. at Wal Mart were they in business back then??

Seeing as I had only one response to plea for a little bit of
reinforcing tape (from JD Stewart, who lives 20 miles away), I
ended up heading to my local WalMart.
Guess what? I'd bet a million bucks the stuff they sell is
EXACTLY the same as the Poly Fiber stuff. (except for the sticky backing)
At the very least...it'll damn sure work just fine!!
From the Poly Fiber product description for their tape.....high
density 100% polyester
WalMart stuff (if someone did't tell you, you wouldn't
know!)..........100% polyester
I just finished Poly Tak'ing it on. I swear, if I didn't say
anything, no one would ever know the difference. BTW, it cost
1/10th the Poly Fiber brand. Not having the sticky backing is only
slightly tougher to apply.

PS. I often find it best to just keep some things to myself (or
share my opinion privately to someone on the list) John H thinks
he's the ultimate authority when it comes to all things Kolb. NOT
in my opinion, he isn't!!
Wow! Comes on begging for a hand out of covering materials and asks
|
what alternative he might use, then doesn't like the answer he
gets. The Gull of some people.

Perhaps we should all remember that Homer wasn't designing a better airplane
he was designing and building a cheaper airplane.
