forestrynick Posted April 22, 2010 Share Posted April 22, 2010 Hi all Doing another challenge event soon and I believe the site is not very wooded. So i need a ground anchor and I really can't afford to buy one. So i guess that means make one. Was thinking the standard spade type anchor would be best. I don't want it to weigh more than my truck but must obviously be strong. Anbody done one themselves, what are the week points in most designs? Many thanks Nick Quote Link to comment Share on other sites More sharing options...

Many thanks Nick oh and yes i've done a search, which was partly useful. But i need clarification and pictures! Quote Link to comment Share on other sites More sharing options...
Jon White Posted April 22, 2010 Share Posted April 22, 2010 Yes, me and Hybrid from hell made a batch of "kittygrippers" years ago. The angles and lengths of the arms are absolutely critical otherwise they simply dont work! We made several prototypes that didnt work before borrowing a pullpal one iirc from Ali Read and copying it! IMHO you're best off buying on these days as i reckon you'll struggle to make one thats as light as the one xeng make for example.

white90 Posted April 22, 2010 Share Posted April 22, 2010 If you can Borrow one to get the angles correct if you are near me you can borrow mine. Quote Link to comment Share on other sites More sharing options...
Night Train Posted April 22, 2010 Share Posted April 22, 2010 Doesn't anyone bother with this type anymore? Would be easy to make and remove and would store easily. Quote Link to comment Share on other sites More sharing options...
white90 Posted April 22, 2010 Share Posted April 22, 2010 But very heavy/slow to use Quote Link to comment Share on other sites More sharing options...
forestrynick Posted April 23, 2010 Author Share Posted April 23, 2010 hmmm Thats not very encouraging. Was planning to have a go making one this weekend for event next weekend. Surely the really important variable is what angle the blade enters the ground? Nick Quote Link to comment Share on other sites More sharing options...
simonr Posted April 23, 2010 Share Posted April 23, 2010 Surely the really important variable is what angle the blade enters the ground? Yes, kind of. The most important measurement is if you draw a line from the point your winch line attaches to the point the arm joins on to the spade. It is the angle between that line and the spade which is most critical. Unfortunately, that angle changes for different sizes of anchor - so you cannot take an existing design & scale it up or down. If the blade is give or take the same area and attached in the same place and the length of the line mentioned above is similar - you can do pretty much what you like! Although the angle it enters the ground is important, more important is what it does when it's burrowing its way through the ground.

Jon ^^^ Wot he said I made a number of units, strong but heavy, angle IS Critical for it to work IMHO with Si Rs anchor you are wasting you time, it is one of those "You can't Make it for that sort of money" jobbie. When fund allow I wil be buying one, as although the one(s) I made work fine and are silly strong, they are also silly heavy. They also cost a load to make, so save yourself the grief, costs, and time and buy a X Eng One Nige Quote Link to comment Share on other sites More sharing options...

simonr Posted April 23, 2010 Share Posted April 23, 2010 However, I have a lot of respect for people prepared to have a go themselves - that's what pushes the technological boundaries. Si Quote Link to comment Share on other sites More sharing options...

landmannnn Posted April 24, 2010 Share Posted April 24, 2010 What about somthing like this folding boat anchor? You could adjust the angle of the blade after manufacture........ Quote Link to comment Share on other sites More sharing options...
forestrynick Posted April 24, 2010 Author Share Posted April 24, 2010 What about somthing like this folding boat anchor? You could adjust the angle of the blade after manufacture........ Saw a miltary version of that today at hursts, thought about it but it weighed too much. Couldn't really find suitable material for the blade so post poning this endeavour. Made some bridging ladders instead! Guess i shall have to beg mates to lend me one next weekend. Nick Quote Link to comment Share on other sites More sharing options...
