In the spirit of upcoming elections and in the finest traditions
politics, I have a total flipflop/turnaround on one of my recently posted opinions. (though admittedly probably not as amusing as McCain announcing that he suddenly decided MLK Day is actually is a good idea after all, but I digress...) Upon further research, I need to modify my statements on torsion axles, too accommodate my new revelation. I have found a torsion axle that seems very promising, made by Dexter. The key thing of interest to me it that is has independent suspension that is customized for your individual trailer, and of course can be made with the square flange on it to accommodate the electric brakes (no flipflopping there!). It has elastomer suspension, like many of the other torsion axles on the market, so being a skeptic I naturally had many questions. I just got off the phone with the Dexter tech guy, who was very helpful and friendly. Here is what he learned me: The axles are all made custom to order, and the elastomers are custom sized based on your specific trailer weight (none of these axles are stocked as "in house" items and all are made to order). The axles of concern to us as glider pilots are the #9 axle, rated for 1000 - 2200lbs, or the #10, rated for 2000 - 3500lbs. Either axle can be fitted with either the flange for 7" brakes (2000lb rating, kinda weak), or the flange for 10" brakes (3500lb rated, much better! I didn't ask about the 12" flanges on these axles though). Dexter need only be supplied with your specific dimensions for your trailer, as well as your gross weight. From that info, they custom load your axle with the specifically sized elastomers for your exact trailer by first freezing them in liquid nitrogen and then slipping them into the room temperature axle where they promptly and permanently expand inside the axle tube. The whole mechanism is completely sealed, and the elasomers are expected to last the life of the parts (although only garunteed for 5 yrs...). The swingarms are permenantly mounted to thier pivots via a pressed/welded square broached arrangement. What does it all mean? It means you can get a kick a%! axle, with independent suspension, set up for brakes, custom suspended for your weight trailer that would be an extremely easy installation, both new or retro. It can be of the heavy duty axle/brake setup, the lighter axle with heavy brakes, et c for a very low cost. I was quoted at $300- $400, depending on the size setup/combo you ordered it with. It is made by Dexter and shipped to any one of their nationwide distributers where you can pick it up in person, thus saving an avoidable freight charge. Included in the price is a new independently suspended axle, custom made to your exact dimensions/weight, fitted with new drums/ brakes, and hubs. All you have to do is bolt it to your trailer, bolt on the wheels and wire it in (2 wires). Although the travel is slightly less than a good leaf setup, the wheels moving independently and with custom matched rubberbands more than makes up for this. As to reinforcing the area above the torsion axle (reccommended highly), just add 4' or so long pieces of 1-1/2 x 1/8 angle iron (or something similar to suit your trailer) in between the new axle brackets and the trailer frame.
