the kid Posted September 20, 2010 Share Posted September 20, 2010 I was having a thought while in a lesson today. Can I get tank traps made? I was thinking of having engineering making some up for a show. + its good welding experience and they have a reason to be making things.Looking on doughty there is nothing about a weight but I guess that if I have a long enough upright and a good enough weight there should be nothing stopping me. The poles are not going to be anything bigger than 2m. Link to comment Share on other sites More sharing options...
AndyJones Posted September 20, 2010 Share Posted September 20, 2010 Absolutly no reason not to. If you have access to any, you could even measure them to get sizes. You could even get creative and cut a slot in them so that they are stackable. once you have made them I guess it would be a good idea to proof test them.

Just Some Bloke Posted September 20, 2010 Share Posted September 20, 2010 A local hire company round my way had some custom made (professionally) and found it was cheaper than buying Doughty tank traps off the shelf. As long as they're strong enough to take what's going on them, then I can't see a problem. Link to comment Share on other sites More sharing options...
the kid Posted September 20, 2010 Author Share Posted September 20, 2010 Ah ok I will have a word with the guys tomorrow then, when I pick up my fixed light. If anyone has one it would be great to get the plate thickness, everything else is easy enough to work out. Link to comment Share on other sites More sharing options...
Brian Posted September 20, 2010 Share Posted September 20, 2010 Looking on doughty there is nothing about a weight... 16kg, 600mm square. So now you can work out the thickness :) Link to comment Share on other sites More sharing options...
the kid Posted September 20, 2010 Author Share Posted September 20, 2010 I will leave that to them... But I did mean "there is nothing but a weight" Link to comment Share on other sites More sharing options...
Just Some Bloke Posted September 21, 2010 Share Posted September 21, 2010 If anyone has one it would be great to get the plate thicknessThe one I've just measured is 5mm thick. That is a Doughty that someone left behind a while ago. If it stays another week then it gets a green and yellow tape mark on it and then, by definition, is ours.

the kid Posted October 6, 2010 Author Share Posted October 6, 2010 Just trying to find out if we can make these. Is the wall of the receiver 5mm thick as well? Annoyingly it could be that we just can't make a bend that tight that thick, and milling would just be a bit crazy and have so much waste. Link to comment Share on other sites More sharing options...
madorangepanda Posted October 6, 2010 Share Posted October 6, 2010 Could you not weld on some form of key clamp or barrel joiner? Admittedly welding something plated can be rather tricky, but it may work out cheaper than getting something made yourself. Link to comment Share on other sites More sharing options...
the kid Posted October 6, 2010 Author Share Posted October 6, 2010 Never thought about a Barrel joiner, BUT the barrels I have are cast, and cast is REALLY hard to weld. Link to comment Share on other sites More sharing options...

the kid Posted October 6, 2010 Author Share Posted October 6, 2010 Thanks... and oh ######. Although logicaly no issue with a square holder just 3 screws... or am I being illogical. Link to comment Share on other sites More sharing options...
ace Posted October 6, 2010 Share Posted October 6, 2010 Thanks... and oh ######. Although logicaly no issue with a square holder just 3 screws... or am I being illogical. In fact I suspect you would only need one bolt, at 45 degrees from a corner - Very similar method to clamping the legs into steeldeck....

Brian Posted October 6, 2010 Share Posted October 6, 2010 Can't you use steel tube? I can't find my BS standard size tables but in the US you could use Schedule 40 pipe; ID = 2.067", wall = 0.154". You might get away with Schedule 80; ID = 1.939" and wall = 0.218" [EDIT]Found them... 60.3mm OD with 5.0mm walls giving you a 50.3mm receiver.
