There were about 117 of them queued when I noticed what was going on. In a nutshell, this guy signed up for all of the Lists and had a "register with my site" spam filter enabled on his account. When his account started receiving List messages, it started sending back, "you need to register" messages back to the various Lists which in turn went to the Lists which in turn got sent to the same spam filter which in turn sent back a message indicating that the List needed to register, and so on and so on until, I suppose, the Internet just blew up! Sheeze, some of these spam systems are so brain dead! Anyway, I've cleaned out all of the messages generated by this thing and put in a permanent block from this cashette.com website so that this shouldn't be a problem any longer. Back to Airplane Discussions! :-) Matt Dralle List Administrator Matt G Dralle | Matronics | PO Box 347 | Livermore | CA | 94551 925-606-1001 V | 925-606-6281 F | dralle@matronics.com Email http://www.matronics.com/ WWW | Featuring Products For Aircraft do not archive ________________________________ Message 6 _____________________________________ Time: 04:42:43 PM PST US From: "dama" Subject: Kolb-List: Tail Wheel Shimmy --> Kolb-List message posted by: "dama" Gents, I cannot deal with this tailwheel anymore. It's a stock plastic Kolb tailwheel on a Firestar II that served me well for 4 years. A few months ago, I felt a vibration on takeoff and realized on landing that it was a tailwheel shimmy. It begins as I slow to about 15-20 mph on rollout. It leaves a nice rubber squiggle mark on the runway and eats the tailwheel away quickly. At first, I thought that the geometry of the wheel had changed from wear and ordered a new one as the old one had worn maybe 1/4 inch after 500+ landings, most on hard surface. The new one does the same thing. I have tried different spring tensions and tightened and loosened the bolt that the assembly swivels on. Does anyone have an idea as to what may have changed?

May be due to the way I made the tail surfaces. Rather than stacking the tubing regarding the trailing edges that's leading you that way. I chose the radius method over the Homers bumps method. Makes for cleaner surfaces. And for you guys like Dave interested in the 1/2 scale P47 that Charley built over 20 years ago inquire off list..... I sent the fuel tank back to Mark for some mods to make it fit today. Ms. Dixie is taking shape and looking more like an airplane everyday! Who else is building out there? Please allow me to share a new product. It's the new sport pilot video magazine DVD! I received my first copy today! There were 2 Kolb's in this issue!

Like the axle worn & allowing wheel to wobble, or maybe a cracked fiberglass rod that is setting up a shimmy? Hopefully you haven't been paid a midnight visit by Possum at full moon where he dances & hops around hooting and clanging that mystery kettle of his as he circles your plane 3 times. If that has happened, legend has it that you might as well accept the fact that it can never be fixed. Good luck. -----Original Message----- From: owner-kolb-list-server@matronics.com [mailto:owner-kolb-list-server@matronics.com] On Behalf Of dama Subject: Kolb-List: Tail Wheel Shimmy --> Kolb-List message posted by: "dama" Gents, I cannot deal with this tailwheel anymore.

You could rebend a little positive bow into it. -BB do not archive On 29, Nov 2004, at 7:46 PM, dama wrote: > --> Kolb-List message posted by: "dama" > > Gents, I cannot deal with this tailwheel anymore.

Snap a line on the hangar floor and put the tailwheel on the line. Then drop a plumb off the nose hoop to get the front of the plane on the line. 2. Went to ACE Hardware and bought two 8' pieces of 3/4 inch alum. angle. Use a bungee cord to strap the alum angle to the outside of the tire horizontal with the floor (equal length of angle in front and behind the tire). 3. Measure from the front of the angle to the line snapped on the floor, and then from the rear of the angle to the snapped line, and rotate the axel up or down until the front and rear measurements are the same. 4. Repeat for other tire. Worked well for me. Call if you have questions at 303-838-2240. Bill in Colorado P.S. I then returned the alum angle to Ace for a refund. I hear ya bill.....but how did you drill for the bolt...did you do any of it on a drill press..or was it all done by hand drill?...and how do you keep the thing from twisting while you hand drill?...and is it under pressure when you drill or is it suspended? Someone said that they had an elongated hole in the Aluminum part and twisted the fitting to the right location then squashed it with shear Manpower on the nut to hold it by friction due to fitting deformation. that seems a bit risky...and indeed that is what I had, but something was unsatisfactory as the wheels would always stray around for me My airplane will probably fly good but landing is somewhat embarrassing when the rolllout is ...er....sideways.
