I had new Mil lenium cylinders and pistons and found their pistons were within =BD gram o f each other (the original Continental pistons varied by about 7 grams). I didn't do any metal removal - just swapped parts around until I got each o f the four sets as close to the same weight as possible. As I recall each set was within less than 1.5 grams of each other. It's worth the effort. Mine is the smoothest running A65 I've ever flown behind. I doubt if it tr anslates to any more power, but it should increase the life of the engine. Jack Phillips NX899JP Raleigh, NC -----Original Message----- t-server@matronics.com] On Behalf Of kmordecai001@comcast.net Sent: Wednesday, July 19, 2006 10:27 PM Fellow Pieters, I thought I would take a little time while the crank is in the shop to bala nce the reciprocating parts in the A-75. Imagine my surprise when I found the rods within 3 grams of each other! From looking at them you wouldn't h ave expected it, but I suppose the irregularities in material on the beam s ides and rod ends were the result of the factory balance work. Lot's of gr inding marks & variation from rod to rod, but the balance is very good. A little work with the grinder and now they're within 1 gram. Pistons are within 10 grams, but will soon be within 1 or 2 :-) I know, this is way overkill for a 2600 rpm engine, but it keeps me off th e streets & justifies the occasional purchase of tool bits. Also smoothed & polished the intake spider, elbows, and ports. Port matchin g was pretty good, but the surface finish was pretty rough with lot's of ve ry rough spots from irregularities in the mold. Once again, overkill for a slow running motor, but maybe I'll pick up a few rpm's in climbout. Looking forward to assembly in a couple of weeks.........

According to the literature, for organic linings they need to get up into the 850F range but if you heat them too much too fast, you carburize the material and it becomes brittle. The heat is required to set the resins that bind the lining material and you want to form a bit of a glaze, but again- too much, too fast is not good. That's why they say to taxi about 1000 ft. to get them hot, then let them cool down, then repeat until braking action is good. The recommendation is to let them cool for 30-45 minutes between runs but I'm worried that if I do that, the brakes might get HOTTER from standing in the South Texas heat! ;o) Oscar Zuniga San Antonio, TX mailto: taildrags@hotmail.com website at http://www.flysquirrel.net ________________________________ Message 3 _____________________________________ Time: 05:47:54 AM PST US From: "Phillips, Jack" Subject: RE: Pietenpol-List: brake job --> Pietenpol-List message posted by: "Phillips, Jack" Tony Bingelis describes how to condition new brake pads. I think it is in the yellow book. Here is an excerpt: "The Product Reference Memo I received with my new Cleveland wheels and brakes states that the "conditioning" may be accomplished as follows: "1. Perform a minimum of six light pedal effort braking applications from 25 to 40 mph. Allow the brake discs to partially cool between stops. " That's it. Apparently the procedure insures that sufficient heat is generated to cure the resins in the linings and yet not cause them to become carburized due to excessive heat.

Douwe ________________________________ Message 5 _____________________________________ Time: 02:47:14 PM PST US From: "Dick Navratil" Subject: Pietenpol-List: Brodhead repair I went out today to fuel up NX2RN and check things out for the flight tomorrow. I found a fair amount of chafing on my fixed gear bungees. The casing is worn thru but all strands of rubber intact. I picked up new bungees today and all supplies to replace them, but there is no one around the airport to help me stretch new ones on short notice. I am comfortable with flying to Brodhead, so could someone who is driving down, bring along a bottle or sissors jack and a couple of blocks of wood to help me repair. I am hoping to be there by 1 pm. tomorrow. Hopefully, with a tail wind and non stop 245 mi.

I'm up here at Brodhead - drove in. The wx has been pretty bad, with lots of storms. Right now, there's only one fly-in Piet, the blue one with radial engine. However, the clouds have cleared and it's beautiful. Also, the new hotel (Earth Rider) is fantastic, especially if you're traveling with a non-Pieting wife! >I wish everybody safe journeys, calm air and strong tailwinds to >Brodhead.

I finally finished up the editing of the 'Building NX770CG', after the stinking lousy Pinnacle Editing Program kept crashing, over and over again. This program has been a pain in the neck ever since I started using it. I finally got it ready to burn some copies, and out of a couple dozen attempts, I have EIGHT discs that didn't burn properly...not a very good track record for that lousy editing program. I now check every single disc, after I burn them. Well, the plane is ready, and all packed, alarm clock set for 4am. I should make Brodhead within the day Friday, unless weather blocks the way. However, the weather is looking pretty good. See y'all there Friday late afternoon, or evening !! Chuck G.
