The last rollcage I built was on the fly. It wasn't a pre-designed idea or anything. It just so happens everything fit together ok. This time I'm going to do it right. Here's what I have so far. All the bends are a 15/16" centerline radius for 3/8" 4130 chromoly tubing. The teal measurements are the linear distance from the start of the tubing to the beginning of each bend arc. For example, you would take a 3/8" piece of tubing, measure and mark a location for each teal dimension, and then bend it at that mark to the angle shown on the plan. Simple enough. I'll be extending the drawing little by little in case anybody wants to build their own. If you want the DWG file just let me know.


Note: The rear support bars are marked as 5" on the drawing. That is a linear distance on the XY plane and is not the actual distance since they are at an angle on the XZ plane. I'm going to cut them at 5 1/2" and grind them to fit.

This is how I used to do mine to and lay out the bends in the straight. Now I use Solidworks 2009 . Don't forget to dim your arc length off the centerline and you will be fine.


Nice job
 
Thanks Sprint. Also, the teal linear measurements are a sum of the straight segments and the arc segment lengths up to that point. I just didn't include their dimensions on the design. It looked rather clutered when I was dimming everything. Eventually, I'll stick em on another layer and turn it off.


Hey, do you have any experience with other Autodesk products that would be better for this? Maybe Inventor, Revit, or Alias Studio? I can get my hands on any of the Autodesk products because my company is a member of the Autodesk Developer Network. I hear Solidworks is superior for product design compared to anything Autodesk has. I just can't get my hands on that one :) .

I've curved the front windshield and added in segment dimensions like Sprint recommended.

Some renderings of the latest stuff. I forgot to make a V outta the back support bars where they come into the rear shock tower body mounts. There are still a few support bars missing also. Anyways, here's what I got so far.

Looks nice now you just need to buy that $10000 mill to notch it and the $3500 tig welder. LOL


Hint with 4130 you will have enough strength you can move that front brace even more forward to get it out of your air cleaner space.


I like it overall


I know Solidworks 2009 I don't know many commands in inventor.


It looks like it does the same thing , but think Solidworks is way more intuitve and easier to use.

I already fantasize about a $10000 Home Depot shopping spree. A mill and TiG setup is just making me drool. I'm gonna go outside and pace up and down the parking lot while chainsmoking thinking about how nice it would be to have. I'm sure you realize how much of a PITA it was to notch the tubing using a dremel sanding drum and various grind bits. It sucked!
