I am not taking credit for this one at all. Some guy across the pond is making a pretty incredible car from hand. i mean no CNC machine. with a drill press, vice, and hacksaw.

http://rcmag.com/modules.php?name=Fo...er=asc&start=0

the CAD drawings in the beginning are incredible as well.

thought you guys might want to see this guys ideas for a 1/8th buggy,

oh and he designed 4 wheel steering in it as well.

!!!

(found it on rctech)

I can only imagine the weight... I cannot believe he is doing all of that cad work and then cutting it by hand... I would try to find someone who wanted me to make them a buggy who had cnc equipment...

In any case it looks great, and I like his method of making the pulleys fit the stock eight diff cases...

My french is bad, but from what I can tell this guy is going to lubricate a midget and place him in a horse. Interesting project.

I think you misread it a bit, he is going to lubricate the horse, then place the midget inside. I do not think he wanted to handle a slippery midget, I know that I would not want to.

Excellent retort. Ahhh it's good to be back.

I agree with pimp, but I also see why he did it. Doing all the CAD work then printing it out and cutting it by hand is far more simple.

Doing all the CAD work then printing it out and cutting it by hand is far more simple.
Based on what?
The best method is CAD designed in solid modeling and then CNC cut. If you want it right, and look nice, and function great, you will cnc your products. I think some of the stuff he has drawn will not be able to be made. Looks great in the picture, but when it comes time to actually make chips it just wont happen. I get that all the time time from the auto product designers

I realize that it would be more simple to CNC it, but maybe he doesn't have the funds or resources to do that? I was simple saying that to custom make a buggy like that FROM HAND, designing it in CAD, printing it and cutting it is far more simple than the usual cut and pray it fits approach which you can't exactly go about when your designing the whole car...At least if he follows all the templates he made, he knows its gonna fit together...

A company is producing this buggy, its old news, there was a thread on it a couple months back :)

Nek · 04.10.2009, 07:56 PM

There are sooo many good ideas to take from that proto it's nuts lol He better start doing some sort of patents on some of his stuff haha.

Too bad you guys don't speak french!!! If you need anything explained more in details I could translate :P

If I ever have that many flat head screws, I think my head would explode. I hate flat head screws.

its me · 04.12.2009, 01:55 PM

ool as hell build but just think about the trucks final curb weight, I bet the screws he got just in the stuff he made already weigh about a pound :)

I remember that buggy, but I never really looked into it deeply.

If you refer to these pictures he posted:

You can infer that he is using PowerGrip GT belts, with a 3mm pitch and 9mm width. Well, that belt type is the EXACT same one I am using for my truggy belt drive conversion!

This guy definitely has CAD skills, but some parts of his design are far from ideal IMO (such as relying on screws to act as bushings in his steering system). The features he has put into it are awesome though! And his choice of material (aluminum) will cause the buggy to be quite heavy I think.

He is using phillips screws? Wow...talk about high tech buggy with low-tech fasteners.

That same thought popped into my head as well. In Europe some guys like to use regular flathead screws, which this guy used in his Solidworks modelling. But c'mon, hex screws are so much better!
