Re: Taylorcraft/Martin wire

Mark would a peace of new wire help to get it run as I am sitting on a roll of new original Taylorcraft wire and would send a peace to you.

Get off it before you bend it!

Chuck apparently we are both hoarders! LOL

Re: Taylorcraft/Martin wire

I love taylorcraft airplanes so i will end up with another one in the future for sure and it would more then likely be a post war and i would need the wire and yes i tend to be a hoarder.Dave have a great Christmas .

Re: Taylorcraft/Martin wire

I'll commit to a minimum of two wings worth of wire.

Re: Taylorcraft/Martin wire

Hi, Yes a part would be best to have as a sample, make a drawing off of and to show. Who ever wants to send me a part, please send me a PM and I'll give you my address. I'll send it back when done.

Key will be finding out the alloy of the wire, anybody know this? It should be on the original print (yes I know) maybe someone has seen a copy or can visit Forrest?
Roughly, how many linear ft per wing for all 4 surfaces?
How does the aileron bay part differ from the full chord part?
What would the edge treatment feature be like that would be preferred?
Each piece can be cut to length and you can specify chamfer, straight, deburr, round, etc. (all affect cost).
That small radius is likely ok but the possible handling issue will be that long parts whip around the end as it comes out of the bender (machine must slow down).

I'm gone a bit over Christmas but can make some calls after. There is also one company in here in KC I'll go stop by. There is risk that some wouldn't touch an "airplane" part but most do just about any industry including medical. This is how springs get made too so it may help on brake springs and the like.

Thanks, Mark

Mark:

If one assumes a 15-rib wing (only 14 need wire) and the chord is 5 feet (ignoring the aileron cut-out & the short rib at the tip) then 5*14*4=280 feet.

Add a bit for FAF so say each Taylorcraft is a 300 feet roll.

Much better to allow the installer to cut the wire from the roll as required.

Material is certainly stainless, but to what spec I know not. 303?

HTH,

Hi Rob,

If you measure and add 2" to account for the unseen wire that is inside the rib at the ends and count aileron bay ribs and inboard ribs you will get 198' for 2 wings. Aileron bay ribs use less wire.

Send me your address at [email protected] and i wltt send you a sample marry Christmas

Re: Taylorcraft/Martin wire

We may differ on the maths, no problem I'd rather have 300' and have spare rather than have 200' and be short!

The essence is that a few feet here and there is only going to make a few cents difference to the cost.

Merry Christmas to all!

Hi Rob,

Martin wire is $.60/ft.

When I was selling my wire I was getting $1/ft. if I recall and what I have left will sell for $2/ft+ when I start selling it again.

I have limited stock so parting with the minimum amount at each sale is very important to me.

That shapes my perception but if it comes at a good price then I think you are on the right track. I would probably go for 400'.

Re: Taylorcraft/Martin wire

I'd just rib stitch it and be done with it. Yeah, the original is great, but it's non-supported anymore, so grab AC43.13-1B and use the approved data and rib stitch. It's no biggie.

Re: Taylorcraft/Martin wire

John,

On the chance I may open the proverbial can of worms, I thought rib-stitching wasn't allowed on aluminum ribs due to the possibility of the sharp ends of the aluminum ribs cutting the stitching. Though I did notice my first Taylorcraft I bought eleven years ago had rib stitching. Just curious. Thanks!

Re: Taylorcraft/Martin wire

FYI guys - there is an STC to use screws and washers on the T-Craft with stamped aluminum ribs. Much like a 7AC or 11AC. I did a T with it a number of years ago. Check your STC listings.
Merry Christmas,
Mike

Re: Taylorcraft/Martin wire

I think you can also use, if I,m not mistaken, the fabric pop rivets like American Champion and Ag Cat use. I used these on my Acro Sport II on the tail and no problems for the last 15 years of acro flying. These would be a good choice for the Taylorcraft stamped ribs. They are also easily drilled if you have to remove them, and they install quick. Several years ago I removed fabric from wings of a 7 AC Champ that was rib stitched, and almost half of the stitching was chaffed thru, and some almost all the way thru. He was lucky it didn't unzip and loose his airfoil. This happened to a Pitts in PA several years ago due to improperly tied knots on the rib stitching, and ended up a fatality. I do think the rivets are a STC approved method to attach fabric to stamped Taylorcraft ribs. Just my two cents worth.

Re: Taylorcraft/Martin wire

I will buy 4 wings worth.

Maybe. I searched here (http://rgl.faa.gov/Regulatory_and_Gu...e?OpenFrameSet) first using the terms Taylorcraft, wing ribs, then the various Taylorcraft TCDS A-696, 699, 700, and IA9. There was no reference to an STC for either screws or Marston and similar pop rivets that I could find (might be buried in a fabric covering STC however). Not saying there's none, but the rivets appear to apply to Champs. Taping the rib cap's potentially sharp edges might delay chaffing when used with rib lacing.

Some general comments on fasteners: https://www.faa.gov/regulations_poli...a/ama_Ch03.pdf

Have done all four methods as a helper (clips, lacing, screws, and rivets) but no expert here.
