This is a link to a toyota bumper that a guy did like you are talking about. Has turned out decent so far.
3/16". 1/4" is going to be heavy as fook and hard to work with (although some people will tell you any less is p*ssy sh*t) The way it's designed with relatively small flat pieces and a large number of bends and braces will hold up just fine.Quote:

nice bumper too, i need to download 'google sketch'. never heard of it.
are you using the pro or regular version?
Regular version.Quote:

The two large tubes coming perpendicular to the face of the front of the bumper are the frame, everything else is the bumper. I could use a shorter receiver tube and move the brace for it closer to the front of the bumper.Quote:

If you redo it with them, you can get an unfolded model and have it cnc cut. Grinding is for suckers.
yupQuote:

I'd guess around 2 bills with material. you feel like sharing that sketchup file? I'd like to see how you assembled that.
robertf2003@neo.
more than a hefty bumper:flipoff2:
that's a really dam good job with sketchup. Did you start with a series of control points or something? Does sketchup let you export to dxf?
its a point cloud, you gis whore ;)Quote:

And I bet if you spent a few days working on it you could even figure out a hack to get the points' coordinates without buying the pro version! :)
well I'll be darned...soneone's already done it!

and apparently some laser cutters will work right from sketchup

holdon I got a better mission for you flem: rewrite the software for your cnc dremel to use sketchup directly! You could even do it in 3D! Just think of the potential for re-creating greek frieze and bas-relief art!
oh and your cnc dremel would be way cooler if you made it a cnc rotozip
dam I'm bored...
What is the purpose of the reciever? Looks good but i would ditch the reciever and add the winch plate for mounting the winch.Quote:

I'd like to have a receiver on there because it seems like I'm always doing the trailer moving at work, and my dad keeps our boat at a storage place in tight quarters so it'd make that easier to park it there.

With the tow points, I would try to keep them as close to the frame mounts as possible. I would even go so far as to pierce the bumper with them and have them go back 3 or 4 inches onto the mount.
That's exactly what I did, if you look at the mount for the shackle, and the mount for the bumper, they are the same piece of metal that goes through the bumper.Quote:

Depending on the winch, you could bolt the winch to the 'front' of the bumper. You would then take the shear stress off of the bolts and the force would be directed straight into the face of the bumper.
You would bolt the feet through the fairlead and the two red dots in this picture. Does this make any sense?
Yes, that makes sense, but would 2 bolts be enough to take the stress of a winch?
There would be four, two going through the fairlead, two through the 'red dots'. You would be taking almost all of the shear force off of them also. I had every intention of mounting mine like this, but was running short of time (and motivation).
you may take the shear stress off of the bolts holding on the winch, but it will still be on the bolts holding the bumper on to the truck
move it way up for pin clearance
lets do it
should fit on half a sheet of 4x8
1/8 or 3/16 or do half and half
what does a sheet of metal run these days
no idea, but a fab shop pays less.
but they will still charge you the same or more than they bought it for
I'm not sure what your getting at, in my experience they charge by material used. That other half will go to other customers.
I bought a 4x8ft sheet of 1/4" for $130ish at Triple S in Houston back in the summer time.
go get some mill plate at bryan iron and metal
I got some cardboard from uhaul today.
I think that Cody at Hughes Fab in Navasoto can cut it out for you, he is a TAMOR member but you may have not met him yet. The bumper looks good i like it
you can get free cardboard boxes from the computer labs on campus fyi, they usually have stacks of them from printer paper
