Subject: Re: Pietenpol-List: Ford hub- bolt safetying ideasDouwe,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 doa 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. Anythinglike that would give more peace of mind. Dan HelsperPoplar Grove, IL.**************Create a Home Theater Like the Pros. Watch the video on AOL Home.

The recent energy surrounding Bill's home made turnbuckles and hard wirebrace wires motivated me to attempt to make an air speed indicator. You may recognize the design as I referanced an old Sport Aviation Article "CraftsmanCorner" 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 somekind 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 thelike...). I built it to the size and shape that looked appropriate for the jobso 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.

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 itworks, it works. My main area of concern would be the top flange, where thespring is mounted - it may flex a bit, which would possibly throw things offa bit.Thanks for sharing.John (R),There were at least a couple of very helpful postings regarding thesevane-type Air Speed Indicators in the last year:Here's a posting from last September:http://forums.matronics.com/viewtopic.php?t=31759And here's a posting from last April (the "Craftsman's Corner" articlereferenced by John):http://forums.matronics.com/viewtopic.php?t=26014These posts should give anyone enough info to make up their own vintage ASI.Bill C. _____
