attaching wooden stringers

[John Loftus]

Hi Folks,
I'm working on my 1940 BC-65. When I removed the wooden stringers they were held by plastic cable ties, many of which were brittle and broken. Is there a better way to attach the stringers? Thanks,
John

I think I used a waxed cotton cord, then coated with shellac.

Not suggesting their use for this application at all.....but there are a variety of cable ties available. The cheap ones....mostly white and inexpensive...tend to degrade when exposed to heat and UV from sunlight. Better are the colored...typically black but there's a variety..that seem to last longer without embrittlement. A quick net search will offer options for weather resistance.

Holding a stringer on, means it needs to last 20-30 years or more in some cases. I don't think I trust a cable tie of any color for that long.

Me neither....cable ties that is for that application. Was just noting the differences in composition and UV exposure. The white ones really pop in the cold under stress. Worthless outdoors if the parts move any.

I've mostly seen tape to hold stuff in place like stringers. White tape like surgical tape or same as what's used in wings to secure ribs via lacing or whatever's needed. Also seen safety wire to hold.

I usually wrap friction tape around the tube where the stringer passes over and secure with safety wire from two directions to so the wood stringer cant flip over. Its my understanding that was the way factory did it back then so I am told. Ive done a number of T-crafts and several Cubs over the years and have done it this way with no problems. I drill a couple holes, (1/16) in the stringer half way between the where it touches the tube and the fabric side so the wire has no fabric interference.

Thanks Mike for better describing what I'd seen. I helped others a few times but never have recovered one myself. I recall the tape and wires though, and asked why and was told the same about the wood deforming and twisting.

I used safety wire on mine to hold the stringers...

Re: attaching wooden stringers

you could use a dab of Proseal
then whatever wrap or tie used can break and the stringer will still be secured in place.

I used Koroseal lacing on mine https://www.aircraftspruce.com/catal...lickkey=155746
