Design Phases 3D model of frame

**67StingrayJ** · 04-06-2019 01:29 AM

Ok, I thought I would just show off my 3D model for the buggy I'll be building soon. Still working on details, primarily the drivetrain. I want a street bike engine, but my wife said she has to be able to drive it so that means no clutch. Ideas please.

Let me know what you think of the cage.

Some additional screen shots...

The best option here is the simplest.
Teach her how to shift.

Chassis looks good but you really need to start with your tires (sizes), then rims (diamond & offset) and work inward to find the inner suspension pivot points then build the chassis to those points.

If you’re gonna start from the ground up, may as well do it correctly.

I would suggest from experience. To make front of the chassis as short as you can and have it work.
The tall stuff up front is kind of difficult to see out of. I know it looks cool on paper. But in reality great out of car visibility it killer.

thanks for the suggestions guys. Keep em' coming. I agree that the front of the cage looks cool on paper, And I know what you mean on visibility keeping it as low as possible. I'll see what else I can come up with. No point in asking for advice if I don't take any of it into consideration.

I did start with the desired tire size, thinking 40s would be cool. But that is Freking huge and I'm not going for a rock crawler here. Think trail buggy, some rocks, some sand, some trips beer runs. I settled on 35" tires with 18" rims. I put them on my new design. in these shots I have the suspension maxed out with 3" of ground clearance to spare. I came up with this based on 2 factors. 1.) The tires will deform slightly on a nice landing 2.) the dirt will deform slightly when landing. This guy explains it all.

ok, my latest buggy design. This would be much harder to build but totally worth it...

Dumb question but what's the difference between red and green tubes on last design?

**67StingrayJ** · 04-10-2019 03:11 AM

no difference other than being better able to tell the difference between upper cage and lower cage.

I like your revisions.. Looks cool. You could probably do some bigger radius lines and still be cool looking with a bit less difficulty.

If I were modelling this I'd build the front bulk head and then the rear. And then tie them together..

You'll love having this model to come back to for years after building this.

Just recently I've been thinking about the radius tubes myself.
