    Subject: Ford hub
    Hey Dan, I've been stewing over the same thing with my ford hub. While there is not much room behind the hub, if there's enough to run about half and inch of the bolt through the back and then drill that end and run some safety wire around the backside of the hub. Something to bear in mind Dan. Before I went with the Ford, I interviewed everybody I could track down who had ever actually flown behind one. This amounted to about ten or twelve guys. In all these interviews, and all my reading, I've never heard of the four bolt hub coming off. A prop was completely lost from a Ford, but he was just bolting the prop to the four bolt hub directly, plus the FAA report stated that two of the bolts were found to be rusty where they had broken, leading to the conclusion that this plane had been flying around on two bolts for a while before the other two gave up the ghost. Douwe

    You can fuel inject a B ford for 100 HP. Lowell frank has one on his piet now. In a message dated 4/1/2008 8:29:30 A.M.

So what can be done to make the A-65 have more power? Carb jetting, more compression, timing, tuned exhaust? How much does increasing compression affect hand propping difficulty? Just sorta thinking out loud guys. BTW, if anyone is near Camden SC there's a guy advertising two Continental A-65's in the Carolina Trader for $500.00. One is disassembled, the other is together.

    Douwe, Thanks for this suggestion. I am going to look at this situation from the very beginning again, and see the feasibility of your idea. I may be able to do a little grinding on the case to give just enough clearance to stick the bolts out the back to snake the safety wire in there. - we shall see. Anything like that would give more peace of mind. Dan Helsper Poplar Grove, IL. **************Create a Home Theater Like the Pros. Watch the video on AOL Home.

    Subject: Home Made Air Speed Indicator
    Hello Group, I've attached some photos of a home made Vane Type Air Speed Indicator I made. The recent energy surrounding Bill's home made turnbuckles and hard wire brace wires motivated me to attempt to make an air speed indicator. You may recognize the design as I referanced an old Sport Aviation Article "Craftsman Corner" by Chuck Larsen. Although, not quite complete I'll share these photos hoping to create motivation to others. I need to add a couple of rivets, paint, and make some kind of sticker to indicate speed. Material: 0.078" diameter spring wire, 0.020" thick 6061 aluminum sheet, two little bolts, two little pop rivets (in place of the duct tape). I found that the spring wire I used required only one wrap to make a torsion spring with reasonable deflection. I made a couple of different size vanes to get the required deflection for "Pietenpol speed". The whole assembly took about two hours to build using simple tools (tin snips, hobby style 18" bench top break, vise, drill, straight edge, belt sander, dremel tool and the like...). I built it to the size and shape that looked appropriate for the job so I measured nothing. My intention is to hang this on the wing jury strut when I complete my Piet project as a decorative air speed indicator, while the pitot tube airspeed indicator is on the panel. This is a fun little project. John E Wisconsin You rock. That's why Blockbuster's offering you one month of Blockbuster Total Access, No Cost. http://tc.deals.yahoo.com/tc/blockbuster/text5.com

    Subject: Home Made Air Speed Indicator
    John (E), Nice little project. Let's see what activity your recent work will generate. I assume that's vintage duct tape you used there to hold things together. Is the entire unit made of .020" aluminum? Seems a bit thin. But if it works, it works. My main area of concern would be the top flange, where the spring is mounted - it may flex a bit, which would possibly throw things off a bit. Thanks for sharing. John (R), There were at least a couple of very helpful postings regarding these vane-type Air Speed Indicators in the last year: Here's a posting from last September: http://forums.matronics.com/viewtopic.php?t=31759 And here's a posting from last April (the "Craftsman's Corner" article referenced by John): http://forums.matronics.com/viewtopic.php?t=26014 These posts should give anyone enough info to make up their own vintage ASI.

    While I don't have the coordinates for the Riblett GA airfoil that Rob and others mention, there was an analysis done by Mike Shuck comparing that airfoil with the NACA 4415 and they are remarkably similar in turbulent flow regimes as well as profiles. The NACA 4415 coordinates are readily obtainable. Oscar Zuniga San Antonio, TX mailto: taildrags@hotmail.com website at http://www.flysquirrel.net

    From: "Don Emch" <EmchAir@aol.com>
    A friend of mine recently discovered this cool little tool. Anybody that is spending time getting really sore fingers from pushing and holding the tiny little nails for gussets really needs to buy one of these! I got one and the thing is fantastic. I wish I would have had this when I built my Piet because the tiny nails were one of my biggest gripes. I'm messing around with Aeronca wings now and am really looking forward to building ribs just because of this tool. It works really slick. Just hold it in the palm of your and and pull back on the shaft to expose the magnet and touch the head of the nail then release the shaft and it pulls the nail up inside all "loaded" and ready for you to just push it in place for nailing. Once you get the hang of it, it is fantastic!! http://www.cherrytreetoys.com/prodinfo.asp?number=19-195&aitem=9&mitem=112&dept=284 Don Emch NX899DE Read this topic online here: http://forums.matronics.com/viewtopic.php?p=174403#174403
