be prepared !, as the Scouts say. Well in the race cars we carry a Leatherman charge TTI and need it in a handy place, I have always hated the method of using a zip tie on a standard sheath idea onto the roll cage like this.
so another quick 5 minutes on the CAD ( days ?? ),
I had a prototype , then I had a 3D print version , then I tried again, and again.
After four attempts, I found the winner.
testing on a real roll cage.
Now to get a proper 3D print version in a nice colour.
I will add an update and then add it to the shop on Shapeways.com so you can buy it in any colour you fancy.
When converting the BMW 6 cyl diesel into other cars the air box can be removed like this
If you are having a catch tank then the exit pipe for the crank case breather seen at the rear hanging down can be cut short and then blocked off in the round turret with a washer and two pop rivets, the hose to the catch tank comes out of the round lid,
DONT FORGET TO REMOVE THE BREATHER FILTER !!! use the swirl cyclone instead of the filter.
BMW part number BMW 11127799366
this fits inside the breather on top of the engine, it replaces the paper filter that always clogs up.
BUT what if you want it in a road car and still want to recycle the fumes from the crankcase well then such a problem arose in the latest conversion.
This is what we did.
cut the air box as in the picture then CAD a model of a converter to make the pipe run along the top of the exhaust manifold
looks like this in the CAD
then we have it 3D printed and it arrives 6 days later and fits perfect
the adapter bolts on , uses an big fat O ring to seal and 4 M4 bolts.
note : do not try to glue up the hole in the crank case breather the oil will get through…everytime
when the engine is in I will update with the pipes fitted.
In the lull before Dakar 2015 I thought I would get some 3D scanning done,
I updated my rig with a new camera and prepared a BMW 6 speed gearbox for scanning.
I after I scan this I will post up the results, should keep me busy over Christmas.
the scanner will get a resolution of 0.3mm after I assemble the 3D model I will add the new gear lever to the model .
what’s the white paint? it spray chalk that wipes of easily after its scanned, it helps the scanner get all the details.
here’s a photo of when we scanned a pre launch Evoque for the Desert Warrior 3,
I have a full mesh of the interior and shell including the door apertures if you have need for it then drop me an email.
In the end we didn’t use the scan in the Desert Warrior 3, we started from scratch and used the Evoque flavour to get a styling angle on the car, although we do use Evoque lights on the race car as they are just too expensive to get made in small numbers.
and for those that are reading this and wonder how to go from a real car to a 3d scan point cloud to a 3d model that can be machined, well the image below is part of the process.
From there we go to this
then to this
the next step is to 3D cut the foam on a CNC upper large machine
this is the old way of doing it, yes I know you think its far ahead of what you do but we have a new way of making the plugs, these foam ones are way too labour intensive and delicate to be cost effective, things have moved on a bit now.
and finally as easy as that, we have a Dakar race car..
