Soren Frimodt Posted January 7, 2012 Author Share Posted January 7, 2012 It's alive!!! First testrun: The angle on the U-joints is very steep because we wanted the winch as far forward as possible. So we had to get a little creative.. Resulting in a modified TDI CV in one end with a rubber boot covering it. and a heavily trimmed U-joint in the other end.

CwazyWabbit Posted January 7, 2012 Share Posted January 7, 2012 Nice When do field tests begin? Quote Link to comment Share on other sites More sharing options...
landroversforever Posted January 7, 2012 Share Posted January 7, 2012 oooooooo Can't wait for some in-the-field testing! I assume you're going to guard it a bit better? Quote Link to comment Share on other sites More sharing options...
Soren Frimodt Posted January 7, 2012 Author Share Posted January 7, 2012 Next is to route the wire. When this is done field testing will begin! So if all goes according to plan that should be tomorrow But lets see.. Yes Ross, we are planning to guard it a bit, it's actually quite scary sitting next to the prop at full speed Quote Link to comment Share on other sites More sharing options...
landroversforever Posted January 7, 2012 Share Posted January 7, 2012 Yeah it was the prop I was thinking about... knowing how fast they have to spin . wouldn't want to get your trousers caught in that!!!! Quote Link to comment Share on other sites More sharing options...
Soren Frimodt Posted January 8, 2012 Author Share Posted January 8, 2012 We just had our first pull test, and I can tell you it's bl**dy fast! We only pulled in first gear just to check how everything worked, but it all worked a treat, the wire went on smooth and everything. Sadly though it was too dark for proper footage, so none of my videos is any good But will take some new ones very soon! Here's some pictures of the wire routing: Quote Link to comment Share on other sites More sharing options...

Bowie69 Posted January 9, 2012 Share Posted January 9, 2012 Lovely Was the cameraman that far back to stop the cable hitting him when it snapped? Quote Link to comment Share on other sites More sharing options...

CwazyWabbit Posted January 9, 2012 Share Posted January 9, 2012 Nice I bet you are well happy with that performance! Out of curiosity what stopped your Landy being dragged towards your victim test subject? Quote Link to comment Share on other sites More sharing options...
Soren Frimodt Posted January 11, 2012 Author Share Posted January 11, 2012 A combination of physics really. The field is slightly uphill, and his tires have somewhat better grip Quote Link to comment Share on other sites More sharing options...
calle-fas Posted January 14, 2012 Share Posted January 14, 2012 It's really impressive! Have you tried any harder pulls? Quote Link to comment Share on other sites More sharing options...
Team Idris Posted January 14, 2012 Share Posted January 14, 2012 Great to see it working. Well done! If there was a clapping hand imoticon, I'd stick it on the end Quote Link to comment Share on other sites More sharing options...
Soren Frimodt Posted January 14, 2012 Author Share Posted January 14, 2012 Well today we pulled a 130" on dry tarmac with all four wheels blocked in second gear Quote Link to comment Share on other sites More sharing options...
calle-fas Posted January 14, 2012 Share Posted January 14, 2012 Lovely. I'm figuring whether there is a need for a support on the outer side of the drum. Have you seen if the winch moves under load? Considering that an axle is supposed to take a quarter of the vehicle weight I guess it shouldn't though. Quote Link to comment Share on other sites More sharing options...
tomcat404 Posted January 15, 2012 Share Posted January 15, 2012 Great work on the winch and thank you for sharing your findings... Does anybody know how this would work with an automatic gearbox?????? would it speed up and down with the strain on the cable through the gears or would you have to keep it in selected 1st? Also have you tried drive assist with it yet??? thanks nath Quote Link to comment Share on other sites More sharing options...
landroversforever Posted January 15, 2012 Share Posted January 15, 2012 Well today we pulled a 130" on dry tarmac with all four wheels blocked in second gear I hope you have a video Soren!!!! Quote Link to comment Share on other sites More sharing options...
Soren Frimodt Posted January 15, 2012 Author Share Posted January 15, 2012 Indeed Sir: Nath, I think it will work extremely well with an autobox and be even easier to control. But we're not much into that sissy-no-brainer gearbox Quote Link to comment Share on other sites More sharing options...
steve b Posted January 15, 2012 Share Posted January 15, 2012 very impressive Soren , I'm sure I saw smoke coming off the 130's tyres So how does it work out for drive-assist ? And any idea of the line pull force? You have no overload protection in the system so what do you think may break first ? The operators nerve or the cable ? Some excellent innovation there guys cheers Steveb Quote Link to comment Share on other sites More sharing options...
Soren Frimodt Posted January 16, 2012 Author Share Posted January 16, 2012 Drive assist is okay, but the wheels do still move faster than the winch, but on purpose, because the wheels are 38,s on coiler diffs and the winch is fitted with a series diff. So it could easily be matched, but we are not sure what works best, one to one gearing or a bit wheel slip. Time will tell.. According to our barnyard calculations the 10 spline shaft is the weakest point in the winch itself, with the 12mm wire being weaker still Quote Link to comment Share on other sites More sharing options...
