Subject: Pietenpol-List: Hurst Airheart brake master cylinder, HELPGentlemen,I hope this finds you all well! The weather in North Texas is great for flying this weekend. I saw a polished aluminum B-25 fly over my house yesterday.Does anyone know where I can get a repair kit for one of these (please see enclosed)? I think these were sold for racing go-carts or something. I foundthem in a VP-2 (Volksplane) that was built in 1974. We're going to have to start over if I cant find a way/source to rebuild them soon...Thanks in advance guys,Max L.

I have one in my shop somewhere. If I can find it I'll see if it's any good. Something tells me it works fine. I'll sell it for cheap.DJ ----- Original Message -----

Subject: Pietenpol-List: Hurst Airheart brake master cylinder, HELPHi Max,Last year I purchased a Pazmany PL4 that was built in 1977 and never flown. It has the Hurst-Airheart brakes on it. The parts are a bit pricey. Be sure to order the correct material. They sell 2 kinds of seals, one for mineraloil and one for auto brake fluid.After a lot of searching I found the supplier in Minnesota. The company is: Tol-O-Matic, Inc. 3800 County Road 116 Hamel, MN 55340 Phone 763-478-8000, 800-328-2178 Fax 763-478-8080 Web Site: _www.tolomatic.com_ (http://www.tolomatic.com) email: _sales(at)tolomatic.com_ (mailto:sales(at)tolomatic.com) All the best,Mitch GarnerRV-4, PL-4************************************** See what's free at http://www.aol.com.________________________________________________________________________________Date: Mon, 2 Apr 2007 06:45:08 -0700

Hello Piet flyers in North Texas, and Arkansas (or anywhere)The planning for the 2007 Ada Air Expo is coming along nicely. We are looking forward to another great day with a variety of warbird aircraft, aerobatic performers, static displays, radio controlled model aircraft, AND a sanctioned BBQ cookoff event. I do hope so that some Pietenpols can make the trip. I'm the airshow annoucer, and I would enjoy the chance of talking about your airplane with a captive audience.

Humidity can change the dimensions of the paper. The changes to the scaling ofthe document when it's printed can also have an affect on the accuracy of thedimensions. When I plotted out the points on the jig I built and then comparedto the full-scale rib plan there was a difference of about 3/4" in the length.I used MDF for the jig and haven't seen a noticable change due to humidity.--------Glenn ThomasN?????http://www.flyingwood.comRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________
