I only asked because the number didn't work for me. Well, I didn't
want to wait any longer so I constructed my own patterned after ones I found on the net. Given the construction time involved, it was not a money saver. $125.00 isn't a bad price to pay for a nice set of tiedowns.

Sorry for the abrupt response.
My fault on the number - the correct one is 601-932-5832. I did an informal test of the unit. Found that most difficult looking dirt around the airport and drove one of them in. It was easy to insert though it took a few minutes. I was impressed by it's apparent holding strength. I was impressed with the design and the execution. The slightly modified claw hammer and the carry bag were nice touches. It comes with instructions that are simple, easy to overlook, but that should be followed. Funny thing about portable tiedowns - for most pilots it is a less than once a year requirement. But it only takes one incident to convince one of the importance. Sometimes it is worse than lost equipment - I had an acquantance killed by an a/c that flipped on him due to a dust devil. Regarding Belvoir pubs. Of all their pubs, I've found Aviation Consumer to be the most easily cost justified. Given the cost of most aviation related items, making just one correct aviation purchase decision, or avoiding one incorrect decision, can easily pay for the subscription. The fact that the entire pub is available online addresses the filing and storage issue. "Justin Case" wrote in message I only asked because the number didn't work for me.

I just built some close to the EAA plans with a little scrap and the rod and u-bolts from Home Depot for about $20. Plus rope and
the hammer of course. http://www.vintageaircraft.org/magaz...ft_tiedown.pdf It helps to have access to a vise and a die set of course. Mike "Justin Case" wrote in message ...

"Maule Driver" wrote in message . com... Aviation Consumer tests resulted in the Claw failing in one case by pulling out a large plug of dirt (presumably funnel shaped). When pulled at an angle, it failed by breaking one of the arms. Failure occurred at 500lbs (straight up) and 475lbs (at unspecified angle). They stressed that tiedown strength varies significantly by soil type. That's not a very good recommendation. 500 lbs is hardly enough. |

We made the EAA ones last year and they worked great but as for total
holding power, the further apart the stakes are, the larger the funnel shape would be and the heavier right? I think either would be stronger than the screw type and you could always use longer rods for softer soil. 500 lbs straight up times three seems like quite a bit of hold down to me. Also I'd think that if there were a storm so large at an event like Oshkosh, the planes that weren't tied down at all and the ones that weren't tied well would be tossed into the ones that stayed put anyway causing plenty of damage. A friend of mine sold his 172 and where it was after the sale had a big storm hit. The planes were all tied down to a tensioned cable going across the apron. The planes all clumped together and flopped over still connected to the cable. These are temporary tie downs we are talking about. I'd like to see that test as well. Like a chain only as strong as the weakest link. If one failed, the other would be sure to follow. Last year I was on the lake on my boat, tied off to several other boats watching a floating concert. There were about 20 boats tied side by side, several of them were little ones, then out on the end was two 30 foot pontoon boats. A storm came up quickly and twisted that line into a J shape, ropes started breaking, cleats started flying around like mad. Many boats were damaged and most of their owners had done nothing wrong except allowing one other boat to be added to the line. My buddies now know why I carry a knife with me almost all the time, so I can cut free before I get stuck in the middle of a mess like that. Wayne "Maule Driver" wrote in message . com... The 'Claw' and the EAA design are different. They both use 3 stakes per tiedown. The 'Claw' uses a collapsible tripod claw that lies flat on the ground with stake holes that guide the stakes inward towards the center. The EAA design appears to consist of a plate with stake holes that allow you to drive the stakes outward. Notably, the 'Claw' specifies that tiedowns should be placed directly underneath the tiedown point (which won't work very well on the tail of a taildragger). The EAA design specifies that the tiedown should be placed so that the tiedown rope will apply pressure at an angle. Aviation Consumer tests resulted in the Claw failing in one case by pulling out a large plug of dirt (presumably funnel shaped). When pulled at an angle, it failed by breaking one of the arms. Failure occurred at 500lbs (straight up) and 475lbs (at unspecified angle). They stressed that tiedown strength varies significantly by soil type. It would be interesting to compare the 2 systems in identical soils. I would guess that the claw would be stronger in a straight up pull but have no opinion on an angle pull. Hope I never have to care. "Mike Z." wrote in message ... I just built some close to the EAA plans with a little scrap and the rod and u-bolts from Home Depot for about $20.

Ron,
That's not a very good recommendation. 500 lbs is hardly enough. They specifically said the soil was not very good and the numbers not comparable to their tests with other systems. However, the spiral type things are worse in any case, according to AvCon. -- Thomas Borchert (EDDH) |

Aviation Consumer tests resulted in ...failure occurred at 500lbs (straight up) and 475lbs (at unspecified angle). They stressed that tiedown strength varies significantly by soil type. That's not a very good recommendation. 500 lbs is hardly enough. I agree and so did AC. I think they said a tiedown should be worth 1600 or 2600lbs. The big question is what can we get from the best 'temporary, installable, removable' tiedowns? And who makes/designs the best? Fortunately, I suspect that most pilots, most of the time, are not faced with having to use temporary tiedowns. The big fly-ins being the big exception. OTOH, when I used to fly soaring competitions, there was the need to setup temporary tiedowns at many airport locations for 5 to 10 days at a time. I managed it by first, NEVER keeping the ship assembled overnight. Obviously a glider-only option but one that not everyone exercised. The trailers they were stored in were beautifully engineered and it was possible to roll them over without damage to the a/c. I justified the daily assembly work and the risk of mis-assembly by thinking 1) Any damage means losing the comp and 2) weather is not the only risk - cars driving around darkened airports where 50' wingspan a/c are parked in non-standard locations are another. How often do cars hit a/c at the big fly-ins? Once the glider is 'in the box' (covered trailer), the question then becomes how to tiedown the trailer. I never did have a very effective tiedown system and too often the trailer was vulnerable but there were other options. Leaving it attached to a vehicle is one. Parking it next to a building and tieing off there was another. Permanent tiedowns were sometimes available. Many of us felt pretty secure with the bird in the box. But I always remember pics from a comp in Chester SC back in the 70s where a mini-tornado or downburst of sorts tore thru the line. A half dozen glider, in and out of trailers as I recall, were thrown around thru the woods. The rest of the line was almost untouched. |
