They provide the method of using up energy in a hard landing, possibly becoming the "shear pin" for your fuselage, especially in an off-field landing. Just my opinion this Wednesday am. Windy lately, here in hillbilly heaven.

I would guess probably so. I found it interesting that they bent evenly across the length from cage to axle fitting instead of just at the top or bottom. I suspect they need a pretty high force and deflection to straighten, and I can try in phases to check that I'm not changing the cross-section. I have access to a good press to try this. > Just one bend may bring the hardness up to the right point. I hadn't considered this, but maybe it's worth a try. I'm still thinking the 7075 AL legs might be more a sure thing and at this point I'm really starting to want a sure thing (as much as that is possible). -Ben do not archive -BB do not archive > > Ben Ransom wrote: > > >--> Kolb-List message posted by: Ben Ransom > > > >Just over a month back in the air and I find that I have bent my > 4130 > >steel tube gear legs.

I think it is customary for heat treaters to supply a certification letter with the heat treatment, verifying that the part is R_whatever. Of course that is not an independant check. The company I used said not being able to get to R46 as I requested was because of the particular alloy. (I bought 4130 from Aircraft Spruce, didn't check further on variations of 4130.) One other factor is leg length (longer moment arm = more bending force). My legs are 2-3" longer than plans. My remaining concern with 4130 is, if I replace with the same legs but R46, will they be great next time, or will they snap? The only thing I can be sure of is that they will be at least somewhat less likely to bend and more likely to snap. I might ask someone at my work if they could model and predict the difference. -Ben --- Larry Bourne wrote: > --> Kolb-List message posted by: "Larry Bourne" > > This makes me curious about a couple of things.

I found it interesting that they bent evenly > across the length from cage to axle fitting instead of just at the top > or bottom. Hi Ben/Gang: Seems you are doing the same testing I did in 1987 and 1988, for 4130 gear legs for my original Firestar. I started out with 1.0X.090" wall 4130 heat treated to RC 42. This was what Maxair was using for their gear legs. I had to start somewhere, so I used their RC number. That was not hard enough and the gear leg, with its long exposed length, was not stout enough. I soon bent these legs. Back to the drawing board. I next tried 1.125X.125" wall 4130 heat treated to RC 48. That pair of gear legs are still down in the basement, only a few of the existing parts that remain from my totaled Firestar. This combination worked, as it still does for the Mark III. To make sure my memory has not gone entirely south on me, I will go down in the Mole Hole and check tube diameters for the Firestar and the Mark III. Well, I am not as far gone as I thought. Sure enough, both sets of legs are the same material and size, with exception of length. Since there is not nearly as much exposed gear leg on the Mark III setup, mine, I get by using the 1.125 X .125" 4130 tubing. I am not an engineer. Think I have said that before, a time or two. However, 4130 tubing in its normalized condition is not very flexible. When it bends, it tends to stay bent. But heat treat it nice and hard, like 48 RC, and it becomes extremely flexible, compared to its normalized state, without becoming brittle. More good news is, at RC 48 the 4130 will still bend 90 deg without breaking. Ask me how I know. I tested both left and right gear legs in an actual extremely hard uncontrolled landing. The MK III had finished flying long before it ever hit the ground. I was merely a passenger.............. I have been using 4130 gear legs in my Firestar and MK III for the last 16 years with extremely good results. I intend to keep on using it. The major mod after I broke the gear leg/axle socket at Muncho Lake, BC, 1 July 2000, was to weld the axle socket to the end of the gear leg, drill for alignment, then heat treat. How do I know I have legs that have been heat treated to RC 48? Braddock Metal Treating will give you a certificate to that effect. Do not take no for an answer if some folks say they can not heat treat 4130 to RC48. Go to a better shop. The internet is a good source for finding a certified heat treater in your area. If not, here is Braddock's url: http://braddockmt.com/ For the Firestar I cut the gear legs to 35.5" and inserted them all the way in the gear leg socket until they bottomed out at the intersection. My old legs have a slight set to them from a lot of hard, heavy, rough terrain (and otherwise) landings. They are just as good as new and ready to go to work when I build another original Firestar.

The best news for me in your msg below is that you feel the legs won't break even with forces bringing them to 90deg or some such wild angle. I guess you're saying that increased spring resilience doesn't necessarily come with increased brittleness or tendency to break. If that is the case, I feel that my set, at 1.125diam x .095wall should be fine on the Firestar, given the 50% gross weight compared to your Mk III -- fine that is, if really brought to RC 48. My confidence in this statement is from my "testing" over the last month -- and in particular the sandbar landing of last Sunday. From what you suggest, even if I had too small a diameter or wall thickness, but DID have proper heat treating to RC48, I would risk bottoming out, or breaking something else, but not the legs. I've gotten some bounce, but I'm sure the flex (amplitude) is not real high. I'll give Braddock a call. Would be nice if they could straighten what I have AND get them to RC 48. BTW, the internet wasn't entirely good enf for me to find a heat treater, as that is where I found the place that I used for my legs and they couldn't get above RC42. At least they were honest enf to say so, and yes, they supply the test certificate too. What really helps is to have the good advice of others who've been there and done that -- so thanks! -Ben --- John Hauck wrote: > --> Kolb-List message posted by: John Hauck > > > Ben Ransom wrote: > > > I would guess probably so.

Buy new 4130, cut it, drill it, weld it, or whatever before you send it to Braddock for heat treating to RC 48. I think you will be happy with that set up and will never know you are carrying a little extra weight. If I understand the type of flying you like to do, then it is more important to get in and out, then back home than it is to carry a little extra weight. Your airplane will probably never know the difference. I doubt Braddock will consider straightening the old gear legs. They are not in that business. Even the straight new stock gets a little warped in the kiln, but it is not enough to cause a problem with function. Take care, john h PS: I have crashed the MK III, bending both 4130 gear legs 90 deg with no brittleness at RC 48. ________________________________ Message 12 ____________________________________ Time: 05:45:41 PM PST US From: "Larry Bourne" Subject: Re: Kolb-List: photo --> Kolb-List message posted by: "Larry Bourne" If I understand you a-right, Paul, what you're asking for is a pretty sophisticated job.

Hi Don/All: Had a good trip. Left the Suzuki at home so I could take the mountain bikes. Couldn't take both, I discovered during the loading process. ;-) Made a nostalgic trip back to the Flight Farm, Monterey, NY, NW of Corning/Elmira and south of the Watkins Glenn International Raceway. Couldn't find Bill and Barbara Lock's telephone number, so made no contact with them. They were and may still own the property. Someone was living in the old farm house and the grass runways and areas around the hangers were freshly mowed. Other than that it was a very quite and lonely place compared to the two flight I made up there in 1988 and 1989. Those were truly the good old days of ultralight aviation. While in the area I visited the Glenn Curtis Museum, Hammondsport, NY. I had seen the museum in 1988 when it was located in the village of Hammondsport. Now it is outside town in a huge environmentally controlled metal building. Nell and I both enjoyed our visit. Got to spend a little time with my old buddy Bob Noyer and his lovely wife Jo in Winchester, VA. Also dropped in on Bob Bean and spent the night in the corn field on his grass airstrip, located a few miles south of Rochester, NY. Ran out of time before I could visit with Denny Rowe near Pittsburgh, PA, but will catch him next time I fly up that way, possibly next Spring. It is good to be able to find Kolb friends almost anywhere in the good ole USA, plus some in other countries, like, ahhhhhhhh, Woody from Southern Canada. :-) Of course we have Johan in Iceland and several in England and Norway, among several other countries. Take care, john h DO NOT ARCHIVE ________________________________ Message 20 ____________________________________ Time: 10:44:37 PM PST US From: Robert Laird Subject: Re: Kolb-List: photo --> Kolb-List message posted by: Robert Laird At 03:44 PM 10/22/2003, you wrote: >--> Kolb-List message posted by: "Paul Petty" > >Kolbers, >Anyone on the list good with a photo editor?

If the result is any good, then have Shutterfly print it... their prints always looks as good as film, as long as the original resolution is pretty high. -- Robert
