steve b Posted February 6, 2012 Share Posted February 6, 2012 Very nice Soren version 2.0 is looking even better , how did you profile the tensioner/layer arms? hi-def plasma or Laser? some very clean fab work going on in the shed there with the Viking Stig cheers Steveb Quote Link to comment Share on other sites More sharing options...
Soren Frimodt Posted February 8, 2012 Author Share Posted February 8, 2012 Hi Calle, once again you flatter us, we are but mere boys having fun, and when people appreciates it, it just making it even better Neither my brother or the guy that's getting the second winch competes in DOS. They might in the future, but we have no plans about going there sadly. But I'm sure we can manage to bump into each other somewhere else? Steve: No laser nor Plasma cutting. Rough-cut with Acetylene torch then finished off with a grinder. We're really intrigued as to see how these tensioner rollers will work out, but only time can tell Quote Link to comment Share on other sites More sharing options...
Soren Frimodt Posted February 15, 2012 Author Share Posted February 15, 2012 Winch number 2 is up and running! I would be surprised if a video didn't show up soon Quote Link to comment Share on other sites More sharing options...
Soren Frimodt Posted February 16, 2012 Author Share Posted February 16, 2012 As promised, a first test video sporting a meter for testing the pulling power: Results where 2,2tonnes dragging the 90 with its wheels blocked on tarmac. With a Patrol tied to the back of it the clamp holding the wire together at the hook came undone at 3,2 tonnes Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted February 16, 2012 Share Posted February 16, 2012 More please! Time to tie it to something REALLY big Quote Link to comment Share on other sites More sharing options...
Soren Frimodt Posted February 26, 2012 Author Share Posted February 26, 2012 Well this saturday we did yet another test at my secret testing facility A video here: And we did manage to break something in the winch, accidently the driver managed to run the hook into the fairlead at quite a pace. This snapped the halfshaft in the winch, right where it had been welded when it was shortened. So really a very predictable break, and it'll now be redesigned to avoid welding as this will always be a weak point. But other than this we are well-chuffed, soft moor's are no longer a problem Quote Link to comment Share on other sites More sharing options...
LandyManLuke Posted February 26, 2012 Share Posted February 26, 2012 Nice What's the next weak point? What will break next time? Surely it's got to be a good idea to make it the cheapest/easiest/quickest thing to replace? Quote Link to comment Share on other sites More sharing options...
Soren Frimodt Posted February 26, 2012 Author Share Posted February 26, 2012 The weakest point will still be the halfshaft, but by welding it we do not get full use of the strength, and therefore the weakpoint comes to early. No doubt it was due to the extreme shock load that it was subjected to, but still we would like get as much reliability as possible. had it braked at the splines we would have done nothing to improve it, because then the weakpoint was where it was suppose to be. But now now it isn't Quote Link to comment Share on other sites More sharing options...
ejparrott Posted February 26, 2012 Share Posted February 26, 2012 Weak point on a Series is always o/s rear half shaft, its the shortest so has the least flex. I wonder if you're suffering the same? Quote Link to comment Share on other sites More sharing options...
calle-fas Posted February 26, 2012 Share Posted February 26, 2012 Wow! This topic is getting better by the post. I'm actually about to source some old rangie axles for this sole purpose. If I ever get the time and skills to complete the project only time will tell. Quote Link to comment Share on other sites More sharing options...
Soren Frimodt Posted February 27, 2012 Author Share Posted February 27, 2012 yes this is exactly the issue, but again we planned for this as the halfshaft is the easiest part to replace. In this case you can clearly see that the shaft has twisted, but as soon as it reached the solid weld it broke. Nice to hear calls! Keep at it mate Quote Link to comment Share on other sites More sharing options...

Soren Frimodt Posted February 28, 2012 Author Share Posted February 28, 2012 My mate who just broke his winch axle, is working hard to get it sorted, among other things he tolled me something that I find quite interesting: At his work they measured the hardness "HRC" of a Paddock shaft as he was running and a old genuine shaft from a series. The Paddock shaft measured 50 HRC whereas the genuine unit measured 40HRC. BUT the genuine unit had the exact same hardness all the way through, whereas the Paddock unit only had this hardening in about 3mm's depth! So basically they use a way to soft material and then harden their way to somewhat of a reasonable result. This is quite interesting right? So from now on he will be running a genuine shaft that's NOT welded. So new testing must soon be done! Quote Link to comment Share on other sites More sharing options...

Cliff Pountney Posted February 29, 2012 Share Posted February 29, 2012 Soren, I had a similar experience with the front shafts when I used to run a series. When rebuilding the axles I bought a set of new pattern parts and they failed very quickly. There were not (probably still are not) uprated shafts for series vehicles so I went back to using good genuine second hand parts.

Soren Frimodt Posted February 29, 2012 Author Share Posted February 29, 2012 Some fresh pictures from the halfshaft-project. My mate's really working hard to make this thing run! He even entered a SpeedChallenge event in the Danish Toyota 4WD club which starts in fourteen days! I'm hoping to be able to get there and shoot some video of the event. The first "real" test of the winch. Anyways here's some piccies: Quote Link to comment Share on other sites More sharing options...
Spongie Posted March 3, 2012 Share Posted March 3, 2012 I wonder if something like this could drive the nokken winch on a 101 with a disco box Quote Link to comment Share on other sites More sharing options...
Soren Frimodt Posted March 3, 2012 Author Share Posted March 3, 2012 Can't see why not, That Nokken winch is a very nice piece of engineering and we're actually considering making something similar as you get a constant wire speed and much better control of the wire on the "collecting" drum. But there is quite some tech in making this all work in perfect harmony Quote Link to comment Share on other sites More sharing options...
Soren Frimodt Posted March 11, 2012 Author Share Posted March 11, 2012 I bring to you Sir's, the long awaited first competition with Viking Winch!: And I will let yourself be the judges on whether it works or not Quote Link to comment Share on other sites More sharing options...
ejparrott Posted March 11, 2012 Share Posted March 11, 2012 Yup.....I'd say it works!! Better than the thing stuck on the hill too..... Quote Link to comment Share on other sites More sharing options...
calle-fas Posted March 11, 2012 Share Posted March 11, 2012 That is crazy Søren! Seemed a bit heavy/sluggish at the start, but I guess that was down to wire tensioning since it suddenly went like a rocket up the hill... How much does wire and wheel speed differ on this car, and what ratio is the diff? Quote Link to comment Share on other sites More sharing options...
Soren Frimodt Posted March 11, 2012 Author Share Posted March 11, 2012 Yeah we are quite pleased as well, we didn't enter in any hopes of winning whatsoever, but at the first rounds, because of the winch we absolutely smoked the competition! But as the track got easier during the day a certain guy kept gaining and eventually, well deserved I might add, took the win. So a second place finish in his first comp of this type, is pretty good. Actually what you are witnessing there is because of the winch/wheel difference, when there is too much grip on the tyres the winch doesn't spool in fast enough, hence why he tried to make the wheels spin to "pick up" the excess wire. But once he was on the slippery stuff it just went ahead Quote Link to comment Share on other sites More sharing options...
