Pietenpol-List: spoke wheels

Post by matronics »

Original Posted By: Michael D Cuy
I'm getting ready to weld the spoke flanges, to the wheel shaft on my spoke wheels, and would like some advice if somebody has any.I need to know how you guys located the flanges (spoke disk) at a 90 degree angle to the wheel shaft, so that when these pieces are welded they run true.Also, I dont have tig at home, just gas. Can these wheels be welded up using a gas welder?ocb________________________________________________________________________________

You can do this afterwelding though too. Another item is to weld each flange opposite the otherwith one spoke hole aligned between the other sides spoke holes. In otherwords offset the two flanges by splitting the difference between holes.This will help you lace the spoke easier. Looks better too.

Don'tquote me on this but I believe my spokes were 8 or 9 gauge and it tooka 5/32" drill to accept them. Counter sinking was done one at a timeby using a standard countersink bit and going deep enough to allow theconical portion/ tapered to seat some in the flange.

Oilcan, If you are refering to side loads on the 4.5" hub. I figure appx.5.25" long spokes with near a 48 degree angle between opposings spokesvertically. This would be greater than most of the wheels mentioned onthis site. I would say that would be more than adequate.Dannymacoil can wrote:> > I am in the process of setting up for spoke wheels...again ! And have> decided to use 16 in rims.

It will depend a great deal on the strength of your spokes. Buchanan's put9 gauge stainless on mine and told me that each spoke could pull 1000 poundsand that the aluminum hub or the steel rim would probably fail at the nipplebefore the spoke broke. While this is linear, rather than side load, they alsotold me that there are at least 11 spokes in tension and compression at allrolling motion. The summary was that if I hit hard enough to break the wheel,that would probably be the least of my concerns....{;~)Warrenoil can wrote:> I am in the process of setting up for spoke wheels...again !

OCB; Others that I have known that have smaller diameter wheels with the stockgear length have had landing problems. The angle of the plane on the gear isnot great enough to get it to stall properly on the flare on three points.You may have to land on the tail wheel and plop it down when the wing isdone flying. Mike Cuy kinda had this as his gear is shorter but with the 19"wheels. He did some bunny hops on each landing until he got used to thenarrow envelope of landing "angle of attack". Keep an eye out forthis...........Earl Myers-----Original Message-----

ocb,I know you'll see homemade wheels in both 18 and 21" styles. Sky Gypsy forexample has 18" wheels. I do not know about 16" ones. Maybe you mightconsider 18" wheels. The proportion looks nice.John-----Original Message-----

If you have ever seen a pic of Howard Henderson's 444 HH , I thinkit's still posted at the BPA web site. You'll notice that the spokes areuncrossed.I've been told that this is strong enough if your not usingbrakes. But braking forces require crossed spokes.

Bob; I know this will stir the dust up but I was told awhile back that thecrossed spokes on cycles were to absorb the wild braking they sometimes geton the race track and the street too. Think about it, the brakes we use onour crates will barely hold the plane for a runup and if you had strongerbrakes, you would wind up on your nose! 9ga. spokes are quite heavy and areoverkill unless you are talking about something the size of a Standard orJenny meaning weight. The current construction of wheels we use areextremely strong and the plane or especially landing gear will difficklearound the wire wheels......... All the holes in the flanges that I have seen have been perp, not angled.How did you come up with them being angled? Bucnanan's will talk to you only if you are buying something from them.That is an IMPRESSION I got from working with them previously.........Bob, this angle thing bothers me a bit....talk to me about that, OK? Offline e-mail would be better so we don't clog the channel here.Earl Myers-----Original Message-----

I'm told that streight spokes were used in the early days without brakes. Imade my hubs from 4130 tubing and plate. Then fit ( right out of thepakage) Harley spokes, with a rim for an 18" tire ( 21" o.d.) to matchPietenpol original prints. I'm still working on fitting brakes, but thecomplete wheel less brakes and rubber is 8lbs. eachpics on http://www.aircamper.org/users/wevans/w ... wheel3.jpg white hub is just temporary PVC pipe bushing inserted to true wheel on theaxle.walt-----Original Message-----

Who have again refused to answer all letters and e-mails !I was at all times polite to them.At any rate,These cycle shop guys want to make my wheels big brauney, and bullet proof.I want to keep them light.Question for you guys who have built spoke wheels: What diameter spokes did you use ?ThanksBob________________________________________________________________________________Date: Sat, 30 Sep 2000 18:28:36 -0700
