Need Help, First front Bumper Build.

I got my steel, tools, and little knowledge. lol. But i am not set on one idea.
i like these style bumpers:
http://offtheback.net/projects.html


Id like to have multiple approach angles and maybe a medium stinger/hightube for lights. mounts for whinch in the future. but basically just like the first url. I now ran into a problem were i am beginning to like tube fenders and will want to build them too. I rarely see any pics with that style bumper(whatever its called) with tube fenders. i dont know if those would look good together.

I drew this picture on paint program just ignore the fenders. (JK style fender idea i came up with)

and i want to find out what program others use to make 3d draw ups so i can further share my ideas and get help.

biggest problem now is im not sure how bumper mounts on bottom side.

Open to any ideas, help, plans, pics, etc... Thanks in advance.

A good thing to do is find a local 4wd drive shop that carries the bumpers. Take a camera with you and take lots of pics of bumper mounting brackets. Then try to replicate at home.

yeah ive thought of taking pictures but i dont know of any places near me nor do i know anyone with something like this. Does anyone know whether the front of the bumper actually contacts the tips of the frame or is there a gap and the only part of the bumper touching the frame is at the bolts. I would think with the gap there is less support. am a right.

If you look closely at the bumper on that yellow TJ, you can see the two bumper mounting bolts on the left frame rail.. next to the winch. I haven't taken a close look at that bumper but I would imagine the backside of the bumper is open.. or partially open, like a "C" channel.

You can do that same setup using some flat stock across the top of the frame rails and across the bottom of the frame rails. Then, start piecing the rest together.. like "pie plates".

Easiest way to do it for the home builder is to use posterboard. Do your entire bumper out of posterboard, then transfer the shapes to the steel and begin cutting/welding.

Check out these pictures of a front TJ bumper. They should provide some insight for mounting and such.

Here's a picture of mine. I just had an idea in my head and went from there. Kind of like beserk said, I started with some flat stock bolted down and just kept adding on to it. Definatley use the poster board!

The paint is a por15 with a duplicolor spary in bed liner over that. I went that rout because I know it is going to get scratched and that stuff is really easy to sand smooth and touch up. As far as strength goes, I boxed the two side completley and left the middle open for easy access to the lights and for the winch bolts. I also plan on adding a front stinger on, but I am going to make to where it is removable. I have it planned out in my head, I am just waiting for my bender to do that project. Make sure you take alot of pics!!!

Those were my thoughts exactly. I didnt want a big old place for mud to sit! And also about the wait concern, I went with 1/8" for the back side and the rest of the bumper is 1/4". So the boxed ends didnt add to much more wait.
