Cullen Posted July 31, 2012 Share Posted July 31, 2012 here's a little something i prepared earlier Quote Link to comment Share on other sites More sharing options...
mikuni Posted July 31, 2012 Share Posted July 31, 2012 I would weld the door shut but im intending on having it street registered so i can compete in tarmac rally and also carbon fibre no weld to good.yeah nah, don't do that. do this Quote Link to comment Share on other sites More sharing options...
Truenotch Posted July 31, 2012 Share Posted July 31, 2012 That really isn't a bad idea! Quote Link to comment Share on other sites More sharing options...
cheerios Posted July 31, 2012 Share Posted July 31, 2012 Haha yep iv thought of that, can you see in one of my pics where the door corner intercepts the guard? I want to cut it there and run it as in the above pick. as thats pretty much where my intrusion bars run. I'll cut it off some time this week and put a pic up and see what you guys reckon, the only thing hindering it is the now mono door hinge. I can make it work but would be the same effort as a gull wing. Quote Link to comment Share on other sites More sharing options...
Yowzer Posted July 31, 2012 Share Posted July 31, 2012 Oh wow that looks so sweet Quote Link to comment Share on other sites More sharing options...
KKtrips Posted July 31, 2012 Share Posted July 31, 2012 One door hinge should be plenty to suspend half a door and some lexan.. Quote Link to comment Share on other sites More sharing options...
Truenotch Posted July 31, 2012 Share Posted July 31, 2012 Will be a laugh making a door card for half a door... Just check the MSNZ regs again because it talks about "door opening" for the rollcage design (not allowed to be over halfway up the door opening). I wonder if some power mad scrutineer could ruin your day because of this? Quote Link to comment Share on other sites More sharing options...
cheerios Posted July 31, 2012 Share Posted July 31, 2012 One factory toyota hinge isn't ample mr kk, she aint no holden lol. Needs a reinforced hinge. Yep i checked the regs on the cage/door scenario and designed the cage to comply, not having the side intrusion over half way up the door, its currently under the (with factory door) by 18mm. I do wonder though in by cutting the door would that change the 'half way cage/door' rule in my favour Quote Link to comment Share on other sites More sharing options...
KKtrips Posted July 31, 2012 Share Posted July 31, 2012 I think that the rollcage will be well UNDER half way up the door opening as the door opening is moving upwards. I would guess the rule is made to make escape gaps big enough. As long as the opening is more or the same as a comparable car they shouldn't have a problem. Edit. Cheerios onto it.

bubblegoose Posted August 2, 2012 Share Posted August 2, 2012 no chris i was just checking the flow of the exhaust port but drawing smoke though it. honestly what do you think we get up too. and a note to just get some ford hinges and weld them on (focus ones are quick release) Quote Link to comment Share on other sites More sharing options...
cheerios Posted August 2, 2012 Share Posted August 2, 2012 haha i like it goose! i shall inspect.. duno if a ford part will find its way onto the car. Will just make my own pin sleeve quick release ones. Quote Link to comment Share on other sites More sharing options...
Vintage Grumble Posted August 3, 2012 Share Posted August 3, 2012 For some reason I thought you were making molds, so you could pop out new fiberglass panels as needed? Or do you plan to do this? Or am I missing something? Wouldnt you want to be able to replace a gaurd easily, rather than have to go through this whole process everytime you have a little rub/incident and damage the gaurds/kit?

cheerios Posted August 3, 2012 Share Posted August 3, 2012 Yep thats correct, this is the 'plug' (male mold note the vents in the top of the guard are filled in to make casting a breeze) off this i'll build the female mold which will then come off in 6 pieces for the entire side. Every little defect now is one more snowball you have to worry about latter so it needs a smooth glossy finish. I'll certainly be keeping the molds as im casting the kit in carbon fibre which doesn't have and much impact durability as the old fibre glass. Estimate this side will be 2.5~3kg when finished.

Vintage Grumble Posted August 3, 2012 Share Posted August 3, 2012 Fucking sweet, i'm much happier now, haha. Very interested to see how you get on with the carbon fiber, i've not played with it yet, but want to have a play sometime soon. Once again, shits awesome, keep on trucking.

cheerios Posted August 3, 2012 Share Posted August 3, 2012 Haha cheers man! You will love carbon fibre bit tricky but sooooo cool when you pop out a good finished product, i gave my mate a hand who does it and its amazing. Especially when its dry casting style vacume moulded , extremely light weight. Quote Link to comment Share on other sites More sharing options...
adamant Posted August 3, 2012 Share Posted August 3, 2012 I am still in awe of this project, every update just makes me more jealous. I've always wondered how gull wing doors in Motorsport go, ie car on its roof?? Quote Link to comment Share on other sites More sharing options...
cheerios Posted August 4, 2012 Share Posted August 4, 2012 yes a good point you raise there! the Mercedes SLS has an explosive charge in the hinges that detonates and dislodges the door if the car senses a roll over. Check this vid out. Fast forward to 2.15. In this test they drop it on an angle so maximum impact is on the door itself, the charge is isolated for testing purposes. In a real situation its all automatic. The special tool they use to remove the door is just a load sensor so they can gauge how much effort is required to remove the door.

mikuni Posted August 4, 2012 Share Posted August 4, 2012 Bugger any kind of electronic solinoid or anything like that. Even with backup power in a sweet crash I wouldn't trust it. Some Helicopters have a similar issue with forward and up folding doors. They just have a quick release pin system so if you get in the shit you just pull a cord and off they come. I've seen them used a bit because the pilots often remove the doors for flying. Very simple and nice and light. Unfortunately I can't get any decent pics, but you get the idea no doubt.
