Why couldn't the shoulder harness strap be attached to an automobile seatbelt retractormounted in the aft fuse? This would allow freedom of movement yet stillkeep you retained in an impact.I see them on ebay for various cars for like $15DJ_=This email has been scanned for known viruses and made safe for viewing by Half Price Hosting, a leading email and web hosting provider.

Pietenpol-List: automotive seat belt retractor for should harness

The same thing was suggested to me by one of the engineers at work. He did addthat the tighter the seatbelt is the better off you are in a crash. He is aavid car buff who races on week ends and is very knowledgeable on stuff like this.He also suggested putting in a single shoulder harness in the front seat. He saidthat a single harness is ok to have mounted below the shoulder because ina crash you body is able to twist instead of being compressed downward. Not quiteas safe as a 4 point harness but it might be a workable light weight solution.Anyone have an opinion on this?Chris T.Sacramento, Ca ----- Original Message -----

Too small a pulleywill cause the cable to fail. There is an AD on the Luscombe because theydid not use big enough pulleys, nor did they leave enough room for biggerones. You would be better off with 3/32" cable over the smaller pulley ifthat is all you can fit. 3/32" is fine for what we are doing and that areais very accessible during each preflight inspection. My Aeronca 50-C prewarChief uses 3/32" throughout. 3/32 is about 1/2 the weight of 1/8".Galvanized is superior to Stainless as it is more flexible and is stronger.> *Aileron cables--they deflect more than 15 degrees at each pulley,> but the plans show 2" pulleys for 1/8" cable.
