bishbosh Posted September 7, 2006 Share Posted September 7, 2006 As my time (to me) is cheap and my wallet empty, I have been playing around with ideas (on paper only) for a rear winch cradle. This is what I have in mind. I have done no numbers yet not even done an FE model as work too busy and only CAD at home . In principle I think it should work pretty well. The idea is to cut out the rear chassis cross member and weld in the cradle as a pseudo replacement. It wont offer the same torsional stiffness to the chassis rails as the cross member would but as the rails are 15" shorter than they used to be I don't see this as much of a problem. I have to mount the cradle this far forward to keep the winch as high as possible without fouling the rear body cross member. This poses a problem as the distance from the winchplate to the fairlead (Which will be on a new RHS bumper) means that there is a real possibility of the plasma fouling on the lower lip of the "letterbox". If I cut the letterbox deeper I weaken the cradle. I could stiffen it locally but that means more fab and more cost / complexity / things to go wrong and not fit! The only simple answer I can think of is mounting a second fairlead in the "normal" position, but that seems like a bit of a waste to me.. This is what the cradle looks like in CAD: The other thing I have been investigating is a fuel tank that sits snugly around the wheelarch and frees up some space in the back. This one is about 17gallons. Obviously fittings have been omitted coz I coundn't be arsed to draw them for clarity! Not totally sure on the radius of the arch but I can fettle that later on. Yes I know I haven't drawn all the plates, but you get the picture. Whaddya think? and more importantly, who can make these for me Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted September 7, 2006 Share Posted September 7, 2006 Hmmmmmmmmmm Your 2 answers are : 1. Like I am going to comment on your ability to draw and do stress analysis on this sort of thing, looks nice simple and well thought out as I would expect.... 2.

bishbosh Posted September 7, 2006 Author Share Posted September 7, 2006 Nige, 1. You're too kind. BTW you may have the same rubbing problem with the detail we discussed.... 2. If you made the fuel tank it'd only have a 2 gallon capacity!! but thanks for the offer anyhow Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted September 7, 2006 Share Posted September 7, 2006 1. Rubbing prob now much better thanks with the antiseptic talc powder you recomended 2. PMSL Git Nige Quote Link to comment Share on other sites More sharing options...
landrover598 Posted September 8, 2006 Share Posted September 8, 2006 who can make these for me I'll ask in work if you like, what thickness do you want?, we've got 6 - 50mm plate and a CNC Profile Burner B) B) Quote Link to comment Share on other sites More sharing options...
Turbocharger Posted September 8, 2006 Share Posted September 8, 2006 Charlie - you might want to think about some more gussets in your diagram, base to side, side to side and side to top. There's likely to be considerably more stress for longer periods than previously... because the fuel tank will stay full for longer now you've got a diesel Quote Link to comment Share on other sites More sharing options...
Mark90 Posted September 8, 2006 Share Posted September 8, 2006 If you made the fuel tank it'd only have a 2 gallon capacity!! That's ok Bish you could fill up at the same time as me Quote Link to comment Share on other sites More sharing options...
