CAD File For Front Bumper?

@SHREDwagon im in NOOOOO way complaint. I appreciate you very much. I'm just trying to figure out what the CNC Plasma guy is saying when he says 'the file needs work before it can even go into CAD'. Is it a file that can be loaded into a CAD for a CNC plasma cutter? He can open the file but says it's not complete or finished.
 
Same file was emailed for jetting and bending. Have him type "zoom" enter "ex" enter. It should have all the cut dimensions and bend angles...
 
@SHREDwagon please, please forgive my ignorance on this. But will this file work in CAD for a CNC plasma cutter? Thanks a ton!!!!
 
Yes it should, they can use a lot of different file types to run the table. The issues I run into most commonly are based on what version a file is saved as (files saved in newer formats often can't be opened by older software - depending on the program used).

What format is the file that was sent to you?
 
Shred,
Just share it in PDF then everyone can look at it and print.
If they want to make changes they can just redraw it. It can not be that complicated of a print.
All the "thinking" is in the part sizes and shapes.
That's what I do with CAD files that I want to give to others.
 
Good Idea - I'll do that from now on for anyone who's interested.

Guess I thought anyone building this would be doing what I did - i.e. jetting and bending. And so would need a CAD drawing to take to the shop. With a PDF, you're limited to cutting each piece with plasma (labor intensive) or having to pay a shop to re-draft it which kinda defeats the purpose.

Also, I'm hard at 'er on V2 which will incorporate, amongst other things: a bench to wax boards & skis, a bong and a waffle maker.....com'on winter

Shred, can you send me the pdf? PM sent with email.
 
I read the thread, and it seems like there is some confusion on what is needed to get parts for the bumper cut. I spend a lot of my time working in/with machine and fab shops, so maybe I can clarify?

Usually, if you want a shop to CNC cut (waterjet, plasma, laser, etc) a part, you would give them drawings (often in .pdf format or on paper) to review and quote. If you chose to cut the part, it would be best to give them a file format that they can use to import the part to their machine. 99% of the time (for 2d parts) this is a .dxf file. Most CAD/solid modeling software can export this file type. The shop will cut the parts and (hopefully) use the drawing to inspect the part before giving it to you.

If you provide only a drawing, the shop will have to re-create the part, probably charging much more money for the extra time spent. Some shops will accept an autocad .dwg file, others may insist on a .dxf. Also, many shops will not like to have dimensions, tolerances or other information on the .dxf file. Often, having these extras in the file create additional work or confusion for the operator.
 
You guys do realize that after you pay for the steel, cut fee's, and someone to weld it up then powder coat you could have saved yourself a lot of time and just paid someone to make you a bumper to your specs. I'm not saying this to get more builds. Your not gonna save any real money. Its a nice bumper he sent me the file months ago. Just saying.

I can have 2 made for $900 welded and finish sanded (not painted or powder coated) from a local professional fab shop. If you'll make me a bumper for $450 then I'll just buy one from you and not mess with this one. Will you? Thanks.
 
So your saying that a fabrication shop is going to supply the steel, input the design into the computer for the plasma table, cut the parts out, press break everything, package up the parts, then you'll have a professional welder fit and burn it all together, then grind and sand it smooth all for $450.00? I dont see it.

One shop will do all that for $900 for 2 of them. Except no packaging because it'll all be done at the same place. I need to find someone local that wants the other one because I don't need 2. If this falls thru then I'll probably order from you.

Spring505 is spot-on.

No ones's "saving" anything fab'ing there own bumper, like Underdawg said. Unless your connected.

I installed an intercooler after I built this bumper and ended up buying a Slee because it would've taken too much time to redesign and weld up a replacement. The Slee was almost perfect as-is - except it needed a removable winch cradle. See? That's why you fab your own - most travelers have different needs.

It's more for customization and a good excuse to drink beer & weld.

I was lucky enough to be connected, but I learned how to weld by building mine. It was my first project.

So you had a shop use the dwg file he sent & had no issues? Thanks.
 
Ha!!!! I know, I'm a cheap SOB.
 
I built my own for around $250 BUT that was due to the fact that I designed it in CAD myself, welded it all up myself, and painted it (no powder coat). After the project was done I looked at my hours of labor and cost of material and realized I would have made like $5 an hour if I had charged around $700-800. Design, fab, welding, finishing, and painting take a LOT of time, and time is money. I could never make any profit trying to fab these for others. For the folks who can, props to you. Here's my build thread. The page I linked to is the 3rd page. It has my budget at the bottom. If you want to see the CAD designs then click on the 1st page.

Uh, no. I busted out the foam board and hot glue and went to work. Then cut every piece out of scrap 1/4" with a torch, and stick welded the whole thing. I was connected because I have several relatives that weld, so I inherited the welder, plate, torch, stick rods, grinders, etc. All it took was my time. Unfortunately, because I had to learn from scratch, I worked a few hours a night over a period of six months to learn and finish my first project from start to finish. If I had to do it again it wouldn't take nearly that long because I have the knowledge and tools that I didn't have when I started. I would have bought one, but I wanted to learn how to weld.
