Greetings to Palmer, Alaska! Tail wheel strut I use is 3/4" X .120" 4130 heat treat to 48 RC. I'll see if I can find a couple photos to attach. I use mine with Maul 6" and 8" tail wheels. Can't remember the length, but think about 6" protruding from the tail post lower tube. These are photos of an old strut I replaced some years ago. john h mkIII Titus, Alabama -----Original Message----- From: owner-kolb-list-server@matronics.com [mailto:owner-kolb-list-server@matronics.com] On Behalf Of Nick Cassara Sent: Saturday, February 17, 2018 12:30 PM Subject: Kolb-List: Replacement tail rod...?

I can only speak from personal experience with steel tail wheel strut. Heat treated to 48 RC, the steel strut has performed much better than the aluminum or fiberglass struts. Steel probably weighs about the same as the standard length 3/4" 7075 solid rod. Difference in weight: Steel tube: 3/4X.120X12" 4130 .807 lbs Aluminum rod: 3/4X12" 2024T3 .529 lbs (Aircraft Spruce didn't list 7075 3/4" rod) Steel 1.8 oz per foot heavier. My tail wheel strut is less than a foot. Don't remember the exact length. The little plate and bushing increase weight. I don't know how much, but not much. I have a Maule 8" Tundra Tail Wheel that I flew with for a period of years. Can't remember how much that weighed. Tail wheel and aircraft performed well. I took it off last time I flew to Alaska thinking I would get a little more speed with the smaller 6" Maule solid rubber tail wheel. Couldn't tell any difference. On one flight to Alaska I swapped my 8x6 tires for 6x6 to see if I could get a little more speed. No difference that I could tell. I am not recommending anyone else use my tail wheel strut or any other changes I have made to my MKIII. However, sure has worked well for me and my style flying.

Hey John, Curious about the steel vs. aluminum gear legs. I have read lots about them on this list and elsewhere. I know that the aluminum will give some then bend if you don't kiss the ground properly. So far I have only hit hard enough to bounce the Firefly, but not hard enough to bend anything. (knock wood). Anyway, do you know if any instances where a landing caused the steel gear to bend? If so , was there damage to the airframe or did the gear take all the abuse, thus saving the fuselage?

If you hit hard enough aluminum or steel may take out the gear leg socket and cluster.

Yes, the bend test has been conducted a couple times. Early on in my MKIII's life the 582 failed climbing out of the local airport. Made a good forced landing in a confined field. Checked it out on the ground, ran it up, and took off. Engine seized about 30 feet off the ground. I wasn't flying when I made contact. Then again in 2004, Muncho Lake, BC. Axle fitting failed during landing on a rough strip next to the Alaska Highway. Both times I got close to 90 degree bends without breaking. The steel legs will take a lot of abuse before the take a set. I don't know how many times you can straighten them. I think I have straighten my current legs 4 times. The longer the leg, the more spring travel and forgiving the legs will be. How far will they bent before they take a set? I really don't know. I think you'll get your money's worth though. Total length of the legs on my Firestar were 35.5". The heat treater at the time had a 36" oven. Here is a photo of them. john h mkIII Titus, Alabama -----Original Message----- From: owner-kolb-list-server@matronics.com [mailto:owner-kolb-list-server@matronics.com] On Behalf Of Stuart Harner Sent: Saturday, February 17, 2018 6:21 PM Subject: RE: Kolb-List: Replacement tail rod...?

I have some hardened steel legs, and when I put on my tundra tires, I decided to land off the strip in my field. I intended to skim the ground and touch down "like a feather". The only problem was I was a bit previous and hit a fairly large roll in the ground at about 50 MPH. I hit hard enough to launch me quite high in the air, and hard enough to flex the cage on my firestar enough for the center post on my windshield to come out of the socket at the top of the enclosure. I had difficulty in putting enough pressure on the cage to reinsert it back in the socket. I checked the legs and could see no sign that they had bent at all. If I had had alum, I would have been sitting on the ground with the bottom of the cage.

I have a question on this subject. I have just replaced the standard (early) Firestar tailwheel ass'y with the new heavy duty swiveling ass'y offered by Kolb. I have an aluminum tail spr ing rod, and I cannot see any fasteners, rivets, bolts, clevis pins, etc AT ALL that secure the front of 5the aluminum rod into the bottom of the tail weldment. So I could not remove/inspect/replace this tail spring, and I also could not remove the tailwheel assembly from the back of the rod. I literally had to cut the spring rod just forward of the old tailwheel, and then I slid the new tailwheel onto the rod. I drilled, reamed, and bolted the new tailwheel. What I am wondeering about is... did the Firestars have the aluminum tail spring GLUED into the steel weldment? I can't see any other way. They wouldn't have welded aluminum to steel. They would not have used flush countersunk bolts and nuts to bolt it in. So absent seeing any fasteners holding the tail spring into the fuselage weldment... how are these springs attached? How are you supposed to remove and replace them? I would have been very happy to machine a new tail spring, because I have the material ( 7075 aluminum main gear legs form the Firestar).

Early on in my MKIII's life the 582 failed climbing out of the local airport. Made a good forced landing in a confined field. Checked it out on the ground, ran it up, and took off. Engine seized about 30 feet off the ground. I wasn't flying when I made contact. Then again in 2004, Muncho Lake, BC. Axle fitting failed during landing on a rough strip next to the Alaska Highway. Both times I got close to 90 degree bends without breaking. The steel legs will take a lot of abuse before the take a set. I don't know how many times you can straighten them. I think I have straighten my current legs 4 times. The longer the leg, the more spring travel and forgiving the legs will be. How far will they bent before they take a set? I really don't know. I think you'll get your money's worth though. Total length of the legs on my Firestar were 35.5". The heat treater at the time had a 36" oven.

"John Hauck" If you hit hard enough aluminum or steel may take out the gear leg socket and cluster. Never done nor know of a side by side comparison of crashes with alum and steel. 4130 if heat treated to 48 RC will give you a good spring, but is not hard enough to break. It will bend 90 deg and not brake. If bent during operation they can be straightened in a press. 7075 alum bends and will break if bent far enough. I used 1.25X1.20 wall 4130 heat treated to 48RC on my original Firestar and my MKIII. James Tripp used my Firestar 4130 legs to fabricate legs for his MKIII with same landing gear as mine.

I know that the aluminum will give some then bend if you don't kiss the ground properly. So far I have only hit hard enough to bounce the Firefly, but not hard enough to bend anything. (knock wood). Anyway, do you know if any instances where a landing caused the steel gear to bend? If so , was there damage to the airframe or did the gear take all the abuse, thus saving the fuselage?

"John Hauck" I can only speak from personal experience with steel tail wheel strut. Heat treated to 48 RC, the steel strut has performed much better than the aluminum or fiberglass struts. Steel probably weighs about the same as the standard length 3/4" 7075 solid rod. Difference in weight: Steel tube: 3/4X.120X12" 4130 .807 lbs Aluminum rod: 3/4X12" 2024T3 .529 lbs (Aircraft Spruce didn't list 7075 3/4" rod) Steel 1.8 oz per foot heavier. My tail wheel strut is less than a foot. Don't remember the exact length. The little plate and bushing increase weight. I don't know how much, but not much. I have a Maule 8" Tundra Tail Wheel that I flew with for a period of years. Can't remember how much that weighed. Tail wheel and aircraft performed well. I took it off last time I flew to Alaska thinking I would get a little more speed with the smaller 6" Maule solid rubber tail wheel. Couldn't tell any difference. On one flight to Alaska I swapped my 8x6 tires for 6x6 to see if I could get a little more speed. No difference that I could tell. I am not recommending anyone else use my tail wheel strut or any other changes I have made to my MKIII. However, sure has worked well for me and my style flying. I went to steel gear legs and tail wheel struts 32 years ago. john h mkIII Titus, Alabama -----Original Message----- From: owner-kolb-list-server@matronics.com [mailto:owner-kolb-list-server@matronics.com] On Behalf Of Gary Aman Sent: Saturday, February 17, 2018 2:01 PM To: kolb-list@matronics.com Subject: Re: Kolb-List: Replacement tail rod...?

Just a heads up about the swivel tail wheel. I bought mine quite a long time ago, so things may now be different. I found that the one I had tended to break away much too soon. The only real problem occurred when landing with a cross wind. The necessity of crabbing caused enough deflection of the rudder that the tail wheel would break away well before I was ready. I once landed at an airport coming back from the Alvord, and there was about a 15 MPH cross wind. I had no problem until the speed dropped off, the wind then kicked me 90 degrees and out into the sage before I could react. I took the thing apart and used a router to extend the detent on both sides, until I had to input full rudder before it would break loose. Use your own judgement however.

Well. my real question is whether it is acceptable to have it glued in, because this one sure looks like it is glued in. I can easily drill through it and put in a bolt, no biggie. But since many people here have far more experience with these airplanes, I figured maybe I would like to know what the advantage/disadvantage is of glue versus bolt. Aluminum sure does NOT like to be glued. In order to get the glued one out it appears that I would have to put a torch on it to heat it and melt the glue, which would melt the fabric off, etc. If it is acceptable to leave it glued then that is the easiest way. But maybe not the safest or lowest risk. ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message kolb-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Kolb-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/kolb-list Browse Digests http://www.matronics.com/digest/kolb-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
