questions on my First bumper build

in my fab class at welding school, we have to choose a project to blueprint out and estimate cost and weld, etc. so ive decided that the time has come to replace that stock bumper.
im basically looking for tips/tricks/any input for a beginner. for material, thinking maybe 3/16 thick steel plate and MIG welding.

i do plan on (one day) adding a winch to the set up. i dont have one yet to measure off of though.
my idea is to have the winch set low and inside, behind the front plate of the bumper for protection, with a fairlead on the front. question is, exactly how much room do i need for a winch? i'll drill mounting holes later, i just need a basic length/width to leave a space. another question- fairleads. are most the same size with the same hole spacing? im thinking of using one of those billet aluminum ones for the synthetic line. there would be a small piece sticking up from the front place for a fairlead.

other ideas are holes for lights and some loops on the front for d ring shackles.

ill post a rough sketch of the design when i have one drawn up. sometime this week i have to measure out and make a cardboard mock up to see how the thing would even look

I don't know the measurements for a winch off the top of my head but if no one else can tell you I'll go measure mine.

If you plan to run a winch I would build the winch mount out of 1/4".

I like to TIG all the stuff I fab just because there is less grinding to make it look good. Or I can stack small and tight dimes for a certain look or if I want the bigger look I'll use a mig.

What type of jeep is this going on?

Going on an 01 tj.. the stock bumper must go!
1/4 mounting plate Wont be a problem at all. If you could, I'd appreciate some measurements just to have a ballpark range.

RM I should have a rough sketch up soon, I like the tube look on jeeps for sure. Is that what thr wife will be getting?

I'll go measure my winch in a little bit.

If I were you I would buy a winch plate then build the bumper around that. That way you don't have to a bunch of drilling,measuring and bend it for the fairlead.

TJ's have a tube crossmember at the front of the frame. How exactly do you plan on recessing the winch? Cut out the crossmember? There is a reason you see very few TJ's with recessed winches and, instead, see them mounted on top of the frame.

Well, It just dawned on me last night that that isnt really possible.. for whatever reason it never clicked that the tube was in the way. quite the facepalm moment i must say haha.

what i think i will do instead, is have my mounting plate rest just above that tube and have a slightly taller front on the bumper where the fairlead will go, which will also offer some protection for a winch. at a later time i might work out a way to put a tube or bar over it, but for the sake of time on this one ill leave it out for now.

today i am working on a cardboard mock up, ill post some progress as it comes along.

youngjeepr thanks for the measurements, i do have a buddy that might have an old winch plate laying around if he hasnt used it.

Here is a -very- rough sketch of the bumper and some of the pieces.
since i cant recess the winch because of the cross tube its just going to go about even with the top of the frame rails and the front will be slightly taller.

Looks good.

If I remember right my winch plate was $40 or so but it was powder coated.

That is along the lines of what I did, I took the pieces I took out of the top and the ends and pieced them together on the bottom, which allowed me to move my bumper up in it's mounts a little. i made it out of some scrap I had lying around, now i'm working on a rear..........

If it wasn't done the hard way, I didn't do it.

Here's the last one I built. The winch is just sitting on there in the pictures but I do t have any good ones with it mounted.

Who knows?
I just know she hates the look of the stock one on it now! This is only a weekend cruiser to the grocery store and maybe a trip to the riverbed or beach.
