Photos attached. Often a welder will make a small hole on the under side of a tube somewhere, to relieve any buildup of air pressure when making the final weld. Was plugged with beeswax, before SeaFoam was invented. I knew a salvage Captain in the Caribbean who had a 4-seat steel tube-&-fabric plane aboard his 90' salvage tug; hoisted aboard and launched by crane., He went to the factory & checked until he found a newly-made airframe that did not leak any air pressure. Then he had it filled with oil, and the filler-hole plugged, and left it there. Added some 20 lbs of weight, but those tubes are NEVER going to rust from the inside out. John H's practise of using tube seal is lots easier & likely just as good. Listen to the experienced pilots!

Fabric can hold moisture against the outside of the tube, and you never see the corrosion between the fabric and the tube. That's what happened in the tail of my Taylorcraft (though admittedly it had been an outside plane for many years). Nowadays lots of people leave the very back lower section uncovered to avoid the problem. -Dana -- (A)bort, (R)etry, (P)retend it didn't happen? ________________________________ Message 27 ____________________________________ Time: 04:59:22 PM PST US From: "John Hauck" Subject: Re: Kolb-List: Re: Rotten cage tubes found.

Might get your attention if you should get involved overhauling Kolb fuselages. Amazing what one finds when he starts cutting out old tubing.

I used it on my FireFly with the technique he describes. Tube seal is nothing more than Boiled Linseed Oil that has been thinned about 50% with turpentine or paint thinner. It's a lot cheaper to pick up a pint or quart of Boiled Linseed Oil and thin it yourself. Make sure it's "Boiled Linseed Oil". One other point, if you have pin holes already, the seal will leak out for some time until it seals it, Can be messy if that occurs. If memory serves me well, the cage tubes on a FireFly are .035 thick. Don't know what your Original FireStar might be. Probably the same. Good luck with the repairs, can you weld? Terry - FireFly #95 P's. Can find the chart for how much to inject into teach tube if your interested. ________________________________ Message 29 ____________________________________ Time: 05:31:16 PM PST US From: Dana Hague Subject: Re: Kolb-List: Re: Rotten cage tubes found.

I realize that; my point was that even _outside_ corrosion may be unseen if covered by fabric (until the fabric is removed, of course)... and that the fabric, if it gets wet, can accelerate the corrosion. -Dana -- (A)bort, (R)etry, (P)retend it didn't happen? ________________________________ Message 30 ____________________________________ Time: 05:35:14 PM PST US From: Russ Kinne Subject: Re: Kolb-List: Re: Rotten cage tubes found.

So I would imagine that he will see near 70 at those rpms.. I do not think I ever saw more than 2 gals an hour fuel burn on the Pup..

I am impressed with both the full Vw installation and also the Half Vw install for the firefly.. that were present at the gathering.. The half vw with a 54 to 56 inch prop lends itself to a low engine pusher such as is on the Ultrastar.. I am planning to build a TRI FLY that will have some ideas from the Ultrastar and Firefly..High boom pusher with training gear..longer gear legs to improve the prop ground clearance.. half vw, Time will tell..:-) Cooling is always the bugger when mounting a half or full vw in a pusher config..

I suppose it works by capillary action and is drawn down into any porosities in the weld. I used it on a couple of paint mixing tanks I built for a customer way back when. Last time I checked they were still leak free. Sorry, I don't remember Locktite's number for it, I just remember it's green.

From: "olendorf" The tubes sure look like they rusted from the inside. The outside of the tubes looked normal. I like the tube seal idea after seeing these tubes. I received some encouraging emails and after thinking about it I guess it isn't so bad. I'll have it fixed in no time. I couldn't have found it at a better time. -------- Scott Olendorf Original Firestar, Rotax 447, Powerfin prop Schenectady, NY http://KolbFirestar.googlepages.com Read this topic online here: http://forums.matronics.com/viewtopic.php?p=158228#158228 ________________________________ Message 36 ____________________________________ Time: 09:31:05 PM PST US From: "Richard & Martha Neilsen" Subject: Re: Kolb-List: 1/2 VW on Firefly The attached photo is the 1/2 VW that was at the Kolb Homecoming 07. The engine and installation was in a word rough looking but seemed to fly well for what it was. I sure would like to see a redrive on one. As for cooling I can't say on the 1/2 VW but my full VW runs a bit on the cool side in the air. I do need to be careful on the ground. A guy called me a few years ago looking to solve a over heating problem he was having with his free air pusher VW. Turned out he was trying to break in the engine on the ground like the Rotax guys do. I tried to convince the guy that it can't be done without a large cooling blower something like they put on the car engines. To this day the guy probably thinks there is something wrong with his engine. Starting my engine cold I can run it for 10-15 minutes at low power on the ground before it starts to over heat. Once I start a fast taxi the temps start to lower. In the air my CHTs never get over 300 degrees.
