Hmmmm

Still can't see how reinventing the wheel with the Timbren system will make your Scamp any better than just replacing the stock axle with one with more "Down" angle on the arms (available from the axle mfg.) to get increased road clearance. And that system looks like a lot of expensive metal and welding.

BTW: Patent drawings are almost never the same as "as built". I would ask Timbren for engineering drawings before accusing the graphic artist of not being able to draw a picture. Remember, after he drew it, engineering would usually have to approve it. I am sure that they will provide correct dimensions if the image isn't correct.

But rest assured, when someone puts up long rambling posts they shouldn't be concerned about negative feedback, as no one reads them anyway.

Here are some data on deflections and distance from frame.

Bob, Timbren actually used cad drawings. The brochure is as far from accurate as their web site where they show two models, sort of argueing against which you get!

But even negative feedback is better than no feedback at all. Isn't that why we post, to get feedback?

Paul, I had considered the Timbrel Axle on our 13' Scamp when ours needed replacing. I had followed a box trailer down the road and noticed how it pogoed along, and figured everything inside the Scamp would have been shaken apart. I know that this wasn't very scientific, as I didn't get a chance to talk with the driver, nor did I know if he may have had it overloaded, but it got me rethinking using this axle. I ended up using a flexiride because I actually adjust my ride height according to my camping needs. We usually twice a year boondock camp where most tent camp, and to get there I raise the Scamp ridiculously high to get over the boulder fields & ruts to crawl behind our 6" lifted Rubicon Jeep Wrangler that sits on 37" tires. Then when we get back home I lower the flexiride suspension down, replace the tires with just 8" rims to get the Scamp through our 7' garage door opening. I love the fexibility of the Flexiride axle.... different strokes for different folks.
Just something else to consider.

Paul,
Nice patina on the trailer!
Looking at your sketch it appears you have aligned your new hub center directly under the old torsion axle center. Wouldn't you want to overlay the original hub travel arc with the new hub travel arc so they align with each other at ride height? The hub location is important not the old torsion bar center.

Except for a 4" lift, that describes my F150. Tell me more about the Flexride?
Some folks seem to take it personal when you don't follow their lead, but I just want specific results, not caring how if it works. Not really afraid of easier and cheaper either!

Russ, in reply let me just say.....DuH!
Didn't THINK of it! Thanks. Hopefully I would have but in the planning (maybe) stage is when to catch it! I do most of my stuff at O-dark:30 'til dawn, so sometimes I shouldn't think so much then. Habits from a lifetime of "nightwork".

The Flexiride axil shaft (mounted in rubber just like all the other brands of rubber torsion axils) has 80 splines to give you the ability to clock your spindle arm up or down to suit your needs at any given time. The splined shaft has a groove all the way around it that captures the single pinch bolt on the spindle arm, so even if your lock nut or lock washer bolt should come loose, the bolt is still captured and the arm will not come off. I hope this is clear enough to envision.

Perfect! Now I need to find data to give accurate (so-so) measurements on normal travel arc of the hub from the Scamp original so I can do some comparisons per Russ suggestion.
Who makes the Flexride?

David,
Universal Group has lots of data, but there are no dealers anywhere near here. What model do you have or recommend for the 13'? Also, what angles would you suggest could give the best "clearance"? UG seems to not want anyone going past the 22 deg (or 24 on the 3500) mark.
Paul

22 degrees downward angle really gets the Scamp high in the air, and looks crazy funny, but really gives great ground clearance to navigate over small boulders. I don't remember what model mine is, but Spec Trac in Mesa Az. has them and will build them any way you want.
