    Subject: Last Flight 2005/Alodine/Corrosion Prevention
    Only thing I Alodine on my MKIII is the engine mounts for the 912. I do not paint them. Initially, I did paint them and had a problem with lose engine mount bolts when the primer and paint wore between the two surfaces. Haven't found it necessary to use a corrosion preventive treatment on alclad aluminum tubing. john h mkIII Titus, Alabama Started on the stabilizers of my Firestar kit Saturday, got one side cut, fitted and Clecoed, and was able to start cutting tubes for the second one. Does anyone have a recommendation for or againsit using Alodine chemical conversion as a no-weight corrosion preventive treatment on the aluminum tails? Bill Berle

    Bill, If the tubes are alclad, (I suspect they are) the alodine won't "stick" anyway. After drilling all the holes in the hinges I got all set up to alodine them. Turned out the only place it would take was the inside of the holes. The hinges were either alclad or already alodined with clear chemical. The pretty gold colored holes were quickly filled with stainless steel rivets so no one can see anyway but I know they are protected. :) You could do a test on a small piece of scrap tube to see what effect it has.

    John That was such a great photo. John W used to give me a rough time about how wide a formation I would fly with you guys. You even got Gary H to move in real tight. I missed Gary at Sun N Fun this year. Ken took a great photo. Got talking about Monument Valley with the wife. She never saw the area. We are going to take a side trip up there while visiting my mother in AZ this year. Sure was neat seeing MV with all the Kolb people and planes at the annual Kolb fly in. Do you think we will ever be able to get the new generation of Kolb guys to gather like that.

    >From 2003 to 2010, the Kolb Gang did not know what a great thing we had going. Yeah, we knew it was great, and it kept getting better until the end. If someone wanted to do it again, I might be able to get these old bones out there. I did fly into and spend the night in the pilot's lounge at MV, Sep 2014. Wasn't the same without the Kolb Gang though, but just as beautiful and mysterious. I love the place, the Navajos, and the excitement of flying to and meeting there.

    From: Charlie England <ceengland7@gmail.com>
    Stuart, Not meaning to take a poke at you personally, but... Alodine doesn't 'stick' to the aluminum. It is a 'conversion' process. It basically corrodes the microscopic top layer of the aluminum, forming an 'converted' (basically a modified oxide) layer that prevents further corrosion of the underlying aluminum. (Very non-tech, layman's description) Alodine works fine on alclad (typically 2024 alloy with pure aluminum coating to protect the corrosion prone 2024), and also works fine on 6061 alloy which doesn't need the alclad to protect it. I can personally testify to it working on both, because both alloys are used in the RV-7 I'm building, and I've personally treated both alloys successfully. The hinges you attempted to treat were almost certainly 6061 or similar alloy, without any cladding. If I were a betting man, I'd bet that you didn't get the surface perfectly clean and free of oils/other contamination, and/or you didn't properly acid etch the parts prior to the treatment attempt. All aluminum has a layer of corrosion on its surface, if it's been exposed to air for more than a few minutes. The alodine cannot 'convert' this layer of oxide; it can only work on aluminum itself. It cannot work through any contaminants, either. The likely reason you got conversion in the holes and not the surface is that the act of drilling the holes removed the contaminants and the corrosion layer. I don't know what alloys are used in Kolbs, but I'd bet that any extruded parts (angle, plate, etc) are 6061 and tubing is also 6061, except for non-structural stuff like aluminum fuel line, which is usually 3000 series alloy. Aluminum sheet could be either 6061 or 2024, but is probably 6061. 6061 is pretty corrosion resistant, so unless the plane will be tied down outside or lives near salt water, alodine might not be *needed*, but it never hurts. With 2024, the alodine process provides an extra 'layer' of protection in addition to the alclad. Tests have shown that alodine provides as much protection from corrosion as the best epoxies or any other actual paint/coating process.

    6061-T6 is not alclad.... 2024-t? is alclad...meaning...that at the mill..the ingot is covered on both sides with a plate of nearly pure aluminum... then sent down the rolling mill...the ingot is rolled into ever thinning sheet...starting with an ingot of nearly 2 feet thick and maybe 12 feet long? Comes out the other end and is rolled into a spool several thousand feet long..depending on the final thickness. the reason to clad 2024 is because of its considerable copper content... Eventually planes with 2024 sheet, if polished too much , will wear through back to the 2024 base metal...

    From: Herb <Herbgh@nctc.com>
    Yep...the only reason to clad 2024 has to do with the inevitable corrosion of the high copper content of the alloy.. 6061 has a considerable content of Magnesium and Manganese... and the base metal oxidizes to form the protective barrier...which suffices on our Kolbs... Most of it is mill marked with Chandler Aluminum in Arizona and with the 6061 t6 designation... I rebuilt a 20 some year old Ultrastar wreck...and the good parts were as sound as a current model... even the steel rivets used back then were serviceable...and much easier to drill out... the feared galvanic effect is not a worry IMHO!! At least over the life of our planes, based on that experience.. I worked at Kaiser Aluminum for a time...in the lab and on the floor at all stages of aluminum production..but my memory is vague now...

    Subject: Re: Alloyed aluminum on our kolbs...
    This raises a question for me... I tried to drill out some of the rivets that were used by the original builder to build the tails (damaged in shipping), and it was very very difficult to do it without damaging the parts under the rivets. Drilling off the heads was possible, but pounding the stems out of the holes without collapsing or denting the tubes was very difficult. Are there more than one type of rivets that are considered acceptable for the Kolb? Anything other than Stainless? Are the Avex rivets (used on the Zenair) seen as acceptable?

    Subject: Last Flight 2005
    Charlie, No offense taken. Actually I put "stick" in quotes specifically for that reason. I understand the chemical process but chose not to delve into it as college chemistry classes were 35+ years ago. These days I have to look up most stuff as memory isn't what it once was. :( S -----Original Message----- From: owner-kolb-list-server@matronics.com [mailto:owner-kolb-list-server@matronics.com] On Behalf Of Charlie England Sent: Tuesday, April 12, 2016 11:56 AM Subject: Re: Kolb-List: Last Flight 2005 Stuart, Not meaning to take a poke at you personally, but... Alodine doesn't 'stick' to the aluminum. It is a 'conversion' process. It basically corrodes the microscopic top layer of the aluminum, forming an 'converted' (basically a modified oxide) layer that prevents further corrosion of the underlying aluminum. (Very non-tech, layman's description) Alodine works fine on alclad (typically 2024 alloy with pure aluminum coating to protect the corrosion prone 2024), and also works fine on 6061 alloy which doesn't need the alclad to protect it. I can personally testify to it working on both, because both alloys are used in the RV-7 I'm building, and I've personally treated both alloys successfully. The hinges you attempted to treat were almost certainly 6061 or similar alloy, without any cladding. If I were a betting man, I'd bet that you didn't get the surface perfectly clean and free of oils/other contamination, and/or you didn't properly acid etch the parts prior to the treatment attempt. All aluminum has a layer of corrosion on its surface, if it's been exposed to air for more than a few minutes. The alodine cannot 'convert' this layer of oxide; it can only work on aluminum itself. It cannot work through any contaminants, either. The likely reason you got conversion in the holes and not the surface is that the act of drilling the holes removed the contaminants and the corrosion layer. I don't know what alloys are used in Kolbs, but I'd bet that any extruded parts (angle, plate, etc) are 6061 and tubing is also 6061, except for non-structural stuff like aluminum fuel line, which is usually 3000 series alloy. Aluminum sheet could be either 6061 or 2024, but is probably 6061. 6061 is pretty corrosion resistant, so unless the plane will be tied down outside or lives near salt water, alodine might not be *needed*, but it never hurts. With 2024, the alodine process provides an extra 'layer' of protection in addition to the alclad. Tests have shown that alodine provides as much protection from corrosion as the best epoxies or any other actual paint/coating process.

    For corrosion protection on my mkiii .. Before I put on fabric I took a syringe, loaded it up with epoxy primer, then put a drip or two on each joint. I let capliary attraction pull the primer into the joints. 2 things, it should keep moisture and corrosion out of metal to metal contacts, and if it helped to stabilize the joints,,,, all the better....

    Subject: Alloyed aluminum on our kolbs...
    This raises a question for me... I tried to drill out some of the rivets that were used by the original builder to build the tails (damaged in shipping), and it was very very difficult to do it without damaging the parts under the rivets. Drilling off the heads was possible, but pounding the stems out of the holes without collapsing or denting the tubes was very difficult. Are there more than one type of rivets that are considered acceptable for the Kolb? Anything other than Stainless? Are the Avex rivets (used on the Zenair) seen as acceptable? Bill Berle Kolbers: Carbon and SS pop rivets use hardened steel mandrels. If an 1/8" bit comes in contact with the mandrel, the mandrel wins very quickly. I have rebuilt all three of my Kolbs, which required a lot of rivet drilling to remove. Learned a few tricks over the years doing that. First, drive out the old mandrel prior to a drilling attempt. You can buy a 1/16" punch that works great, or use spent mandrels. First grind one end square (flat). Use small Vise Grips to hold the mandrel. The drive them out. To prevent the rivet from spinning while drilling I made a small tool out of a piece of hack saw blade. I grind a notch in one end, beveling on one edge. Push this under the rivet head as far as possible to lock the rivet. If the rivet is not for a structural part, I use common hardware store aluminum rivets. Easy to drill out. All my Lexan is attached with aluminum rivets. john h mkIII Titus, Alabama

    Subject: Re: Firestar tail boom length...
    Herb although it would be a custom, unapproved, unsupported modification, from an aerodynamic point of view it is possible to use a slightly shorter tailboom with a slightly larger size tail to achieve the same "tail volume" as a longer tailboom and a smaller tail. So for example, you can lay out the drawings of the tail surfaces of a stock Firestar, and measure the square foot area. Multiply this by the distance between the center of that tail area and the center of gravity for the whole airplane. You will get a CUBIC foot dimension (sq ft of area times linear ft of tailboom), which is expressed as "Tail volume". If you shorten the tailboom by 6 inches or a foot you can compensate by enlarging the tails proportionately according to that formula, and you SHOULD THEORETICALLY have the same flight characteristics as you would have with the stock design. It never works out exactly the same, but it will likely not be unsafe or dangerous. There are significant common sense limits to this of course. But the point is that if you want to build a Firestar and your longest tube is 12 feet long, you are not "sunk".

    A lot of the guys on the list know each other, either from flyins or cross country stints...so the List Gods tend to tollerate small transgressions from time to time.... the general attitude is one of a bit of tolerance and the list Gods generally say..."go forth and sin no more"! :-) Herb On 04/12/2016 06:01 PM, Bill Berle wrote: > > > "Greg Taylor" <gtaylor35918@roadrunner.com> > > Good video, Christ has pay the prince for our sins, it is by God's Grace that we are Saved. > ----------------- > > What's this have to do with Kolbs? > > Can I post all of my other non-Kolb stuff here too? > > > -- Signature text; Fort Marcy Park?

    Subject: 447 Head bolt torque...
    From: Herb <Herbgh@nctc.com>
    Already in trouble with the list Gods...forgot to change the subject line...!! Now...to show how forgetful I am...got an email from the guy who bought my Firefly... I told him to be sure to re torque the cyl head nuts/studs.... I think the correct torque is 195 inch lbs. or 17 ft lbs...that correct? They do loosen up ! considerably... I think I also told him that I would change the cooling fan belt...since we have an unknown with it...

    From: David Kulp <undoctor@rcn.com>
    Hi Folks, Lots of discussion recently about building and re-building. Attached is a link to a video about building an aircraft that you may find interesting and encouraging. I think the aircraft being built is fashioned after the Kolb Mark III design, so you may get some ideas for shortcuts if you watch closely. Dave Kulp Bethlehem, PA http://safeyoutube.net/w/ZMo
