bishbosh Posted October 2, 2005 Share Posted October 2, 2005 Spent a bit of time messing around with CAD today.... So who's going to build this for me then... The red bits are internal and the grey bits go on the outside. Quote Link to comment Share on other sites More sharing options...

Mark90 Posted October 2, 2005 Share Posted October 2, 2005 I'm not really sure red would go with the wood and leather interior. Quote Link to comment Share on other sites More sharing options...

cols110 Posted October 2, 2005 Share Posted October 2, 2005 Nice, but gotta agree with Mark, the colours will clash. Quote Link to comment Share on other sites More sharing options...
bishbosh Posted October 3, 2005 Author Share Posted October 3, 2005 Well of all people I'm suprised Andy didn't comment on the colour scheme! I suppose being red it didn't even hit the radar! Twas only meant to make it easy to differentiate between in and out. Tsk, some people, I ask you! Mr Beast, where do you think I got my inspiration!

Astro_Al Posted October 3, 2005 Share Posted October 3, 2005 Mark90 - Bishbosh - try to have the bars which go to the point behind the driver's head all meet at the node, rather than a few inches away as some of them seem to. Maybe it was just for clarity, but I though I'd mention it... By the way - what was that done in? I'm on the look out for a cheapo simple CAD program for whacking some tubes, axles, gearboxes etc together on 'paper' - any ideas? Al.

Mark90 Posted October 3, 2005 Share Posted October 3, 2005 Actually looking at the bit behind the driver I think you'd be better with a more traditional full internal hoop here. Can still have mountings going out to the external roof bars. Quote Link to comment Share on other sites More sharing options...
Astro_Al Posted October 3, 2005 Share Posted October 3, 2005 Oh is THAT why it's offset like that? Ok, sorry I see now. I wasn't sure what it was going into (a kids playground?). Hmm, ok, well unless you start doubling up tube runs - one inside, one out, I guess you have to leave it like that. Al. Quote Link to comment Share on other sites More sharing options...
bishbosh Posted October 3, 2005 Author Share Posted October 3, 2005 Astro – the reason for the node separation is to only have one transverse bar. A short length of tube with a properly designed bolted splice through the roof panel will be plenty strong enough for the moments generated from the eccentricity. In reality the eccentricity is not likely to be more than 100mm I would estimate. If I put the transverse bar internally I would loose the plan triangulation which I think is extremely important. As for software – I drew it in a popular CAD package which isn’t cheap I’m afraid. Mark –I started off with a traditional hoop, but changed it to remove the top horizontal, then modified it to have straight (and therefore stronger) bars from the top node to the chassis rail. The downside to this is that there is less protection for the occupants in a side impact scenario. I’m still debating whether or not to add it back in…..

Mark90 Posted October 3, 2005 Share Posted October 3, 2005 Well I suppose straight bars are easier to bend and therefore cheaper to make/fit. Quote Link to comment Share on other sites More sharing options...
