Have you considered the Aviation Products wheels which are sold as the homebuilder special wheeels by Spruce? They are lighter than the Matco and are very good. If you take off the Scott you can sell it for probably more than the cost of a new Matco depending on the condition. I have sold some pretty beat up Scotts for $200 and I have seen them in good shape on Barnstormers for over $400. They are somewhere around $1,000 new. A lot of people withe certified planes remove their Maule tailwheels which have a lot of shimmy problems and replace them with the Scott.

Granted, using 1/4" bolts will give you almost twice the strength of 3/16" bolts, but if you're using AN bolts, the 3/16" size will give you approximately 2600 lb in shear, and 2800 lb in tension (per bolt). If you're going to be putting that kind of load on your aileron pulleys, you've got other, bigger concerns to worry about (like ripping the bolts through the spars, for one). So. I'm guessing that you must have some other reason(s) for wanting to "super-size" your fasteners.

Castle Rock, Colorado ________________________________ Message 10 ____________________________________ Time: 01:04:24 PM PST US From: "Graham Hansen" Subject: Re: Pietenpol-List: Re: jury strut bracket placement I made my wing struts from Aeronca front and Taylorcraft rear struts some 38 years ago. The welded-in bushings on the Aeronca struts (for jury strut attachment) were located in such a way that, when the struts were cut to length for the Pietenpol, the jury struts joined the lift struts about 6 inches outboard from the mid point. At the time, I never even considered the possibility of harmonic vibration; the jury strut position was dictated by the bushing placement. So, quite by accident, my jury strut attachment avoids the possibility of harmonic vibration developing. And as a bonus, my jury struts are shorter (and lighter!). Several have stated that mounting the jury struts at the mid point hasn't caused any problems, but it still is good practice to place them slightly off the mid point of the lift struts. I was lucky in my ignorance some 38 years ago. [As an aside, I flew my Pietenpol last Friday (Dec.14) for 30 minutes--quite long enough at -5 degrees C (about 23 degrees F) with an 85 mph wind blowing past one's ears. The airplane didn't mind it, but I was glad to get back on the ground to warm up. I'm not as tough as I used to be; perhaps a bit smarter, but not much.] Graham Hansen (Pietenpol CF-AUN) ________________________________ Message 11 ____________________________________ Time: 02:32:56 PM PST US Subject: Re: Pietenpol-List: tailwheel From: hvandervoo@aol.com Oscar, Flying and landing with it on Pietenpol NX15KV, I would?use it again.

Oscar,
 
I installed a 6" Matco on NX520SF last year, to replace the used Scott 2000 that she came with.  I'm  pleased with it, but had to shorten my leafspring (shortened J3) to keep the wheelbase about the same.
The Matco's tire contact patch is much farther aft of the mounting bolt hole than the Scott. The whole assembly is about 2 - 2.5" longer. This gives it a longer lever arm and resulted in more spring flex, to the point that the Matco's steering axis was angled aft rather than forward when loaded.  Shortening the spring put it back where it belongs.  Still using the Scott tension springs, and it works great. Steers easily and does not release until you want it to.  They redesigned the mount last year to reduce steering effort. Added another .75" to the length of the kingpin and bushing, and added a grease fitting, so make sure you get the newer design.  I think it's a well engineered design and recommend it.
