hitch im going to make for my car

probably gonna stick weld it. 6010 root with 7018 hot passor 7018 all the way doing 3/8 fillet with 3 passes Attached Images
Reply:-so you bought a factory hitch, didn't like the looks of the welds and havere-designed the hitch?-If this drwg. is anything close to scale, suggest you might want to study things some more, or consult with Ed Mac.Blackbird
Reply:no its not to scale i just had a desighn in my head and wnated to draw it outi stick have to make mesurements for everythingmeasure twice cut onceoh that was the hitch my dad bought and i dont have two hundred dollars so im going to make one at my tech center hoepfully
Reply:What exactly are you trying to do here? That sounds like a lot of weld for such small looking material.72 Chevy Cummins Project94 3500HD Welding Rig build Sold NOV 2011
Reply:its gonna be 312 thou thickness and it probably dont need a 3/8 fillet but i like to stick weld.what ever you guys think just say it thats why i posted it on here thanks
Reply:It does not look like a good design to me, it does not look structural. I think you need to go back to the drawing board.72 Chevy Cummins Project94 3500HD Welding Rig build Sold NOV 2011
Reply:by just looking at the drawing it looks weak at the center.. triangles are your friend.. hard to say though if the drawing is out of scale..tackleexperts.comwww.necessityjigs.comhttps://www.facebook.com/groups/mach...dingequipment/
Reply:everything is oversized herethat square tubeing is not going to be nearly that long ill draw one to size lateri thought maybe the gussets would help

Reply:^^ saw that coming. I think you should draw it to scale, THEN start asking opinions and getting feedback. I agree with sundown in that this is too critical a part to be learning to weld on. If any of that fails, you will be looking at injury or death to you or others, and thats not a risk that I would be willing to take. Honestly, I wouldnt want to be behind you with a design like that. Scale it up, then bring it back and get the answers that you need

Reply:I think you should use bed angle iron and you sit in the trailer your going to tow and have the wife take you for a ride on the interstate. Sorry but that will really wind them up. Your gonna get it now. See this kind of stuff is a pet peeve for some on here. So sit back and enjoy the show.

Reply:I'm with Sundown and others on this.    don't learn to weld on a hitch.    the lateral forces in a sharp turn will just turn that center bar into spaghetti.  You will be able to see that when your car is upside down on the road with the trailer jacknifed around itTiger Sales:  AHP Distributor    www.tigersalesco.comAHP200x; AHP 160ST; MM350P,  Spoolmatic 30A; Everlast PowerTig 185; Thermal Dynamics 60i plasma.  For Sale:  Cobra Mig 250 w/ Push-pull gun.  Lincoln Wirematic 250
Reply:That design is made to fail even if it were flawlessly welded. The tongue has disproportionate leverage over the crossbar.Study successful hitch designs a bit. Learning is good, but even if you can WELD safely a bad DESIGN can fail causing damage, injury or death!Thick stock and overkill won't save a sufficiently poor design. Keep studying and don't give up making things.
Reply:also just about all of those welds are fillet welds, no need for a "root" and "hot pass" those are butt weld terms, just weld it straight up with 7018.

Reply:i appreciate all the advice but im just gonna say that this hitch is not a project im gonna "learn how to weld on"most anyone can lay down a bead weather it be good or bad. but it takes a weldor to read a puddle and react to what the puddle is doing. that could mean reading if its to hot or to cold, wrong angle, arc length to short or two longeven know im only in my second year of welding at my tech school i have applied my self to welding and learning as much as i can in school while it is free.the reason i say i learned to read a puddle is because i like to experiment. what happens if you do this or do thatthe other kids do what the teacher shows them so thats all they see is that one way to run a beadand as far as the desing goes it can be changed. thats why i poseted it on hear to get advice on the structure not everyone telling me i need to know how to weld first

Reply:grand prix
Reply:if you do twice as good welding as you do solid modeling you will still fail miserably.That is so unreasonably bad I can't believe my eyes.  It doesn't even begin to resemble a usable design.Not even bothering to try to draw it even somewhat to scale is a complete waste of our time.I wonder if this is just a troll
Reply:Remember there is also a big step between a welding student and some who has been out in the field for a couple of years. In an earlier post you stated that you ran 3/32 7018 at 77 amps and I'm pretty sure there are guys on here that can possibly run that rod closer to a 100 amps on the same joint then what you can. You really can't beat time under a welding hood. Reading the puddle doesn't mean a thing if you don't have an eye for designing/fabricating because a bad design will turn any amount of steel into scape. Also cut back on experimenting and if you really want to learn, try welding everything you do out of position and always wrap you corners.
Reply:ill post a pic of overhead and vertical mig is vertical considered out of position77 amps with 3/32 7018 worked for me.i have ran it at 85ish amps but thats only if i want to speed things upis this better Attached Images

Reply:id hate to break it to ya but that is a factory hitch made specifially for my car so.......I will say that the vertical plate that meets the flat plate on top is supposed to be one piece with a bendother than that this drawing is the factroy hitch
Reply:The only thing worse than a bad weld/terrible design is a damn fool that thinks he knows more than he does and wants to argue with people who've been designing/fabricating/welding for years.Second semester welding class.  Yepper.  Damn near an expert.Son, you're argueing with guys who've (in some cases) been at this game for 40+ years.A "bad design" will destroy a "good weld" any day.  Weld bead don't mean crap if the base metal fails.  A chain is only as strong as it's weakest link.You've got "a long time" before you're ready for prime time.  Some people go to school to learn physics, metalurgy, etc.  Some learn in the school of hard knocks, but there are basic priciples that must be learned before you take on projects that put others at risk.Syncro 250 DX Dynasty 200 DXMM 251 w/30A SG XMT 304 w/714 Feeder & Optima PulserHH187Dialarc 250 AC/DCHypertherm PM 1250Smith, Harris, Victor O/ASmith and Thermco Gas MixersAccess to a full fab shop with CNC Plasma, Water Jet, etc.
Reply:when did i argue with someone. i said im confident with my welds and if the design needs work then so be itbut DSW said the second design wasnt suitable either which shows what he knows because this is the design from draw tite ( i didnt put the bracket on top of the plate for the tongue weight)http://www.draw-tite.com/content/pro...020&part=36241
Reply:If you want to pull a trailer trade in your Pontiac for a truck. Don't go wasting your time to design a hitch for a car that shouldn't even be pulling a trailer. Just my .02I can remember in the 7th grade my mom said "people will offer you drugs" by the 10th grade I was like, "where the hell are these people?"
Reply:Your etch-a-sketch drawing doesn't look at all similar to the draw-tite picture from where I sit. You are still missing the point. Just because you drew up something that looks similar, doen't mean it will work. The engineer designed that hitch that way for a reason, not because he felt angles and brackets were cool. The spread angle on the uprights acts like a brace to limit side movement at a minimum. I don't see that in your drawing. The angles at the top are most likely mounting points to resist front and back twist from tongue weight rather than going with a long mounting bracket similar to what is shown in their header for a truck. Again missing from your drawing and again it looks like scale is something you need to work on...Oh and you do realize this is a light weight tow hitch correct? Rated for a 3500 lb trailer at best? You are not going to be able to turn this into a 2" reciever and tow anything more no matter what you do..No government ever voluntarily reduces itself in size. Government programs, once launched, never disappear. Actually, a government bureau is the nearest thing to eternal life we'll ever see on this earth! Ronald Reagan
Reply:One word comes to mind. Humility. I'm going into my 5th year of apprenticeship. I can't imagine what my foreman would be saying if i responded in this manor. Most likely would be told not to show up in the morning. There's times u just have to bite your lip.
Reply:i dont think id be able to build it any way no matter how good the welds are or the designits a big liablilty for the instructor/school to let someone build it anywaydidnt mean any disrespect
Reply:So, you can buy that hitch for about $200 from draw tite. Takes 35 minutes to install. figure on an hour since tou don't do it every day, at shop rate of $65 and you're into it for $265. Or you can make it yourself, find the right plate, cut it all out (2 hours) get everything bent right (2 hours), build a jig (3 hours) to hold everything in place, weld it (1.5 hours), powder coat it (probably around $100 bucks depending on the shop) then install it (1 hour).  total time, at least ten hours (probably more) plus materials, total cost at least $700 (counting labor) I don't know about you, but I think I'd rather save the time and money and just buy it. My time off is more valuable than that. I understand the feeling of doing something for yourself, but pick something better that won't use public roadways.

Reply:Was just wondering what you were going to pull with the car?......Anything bigger then a shopping cart would bog it down I would think. Most cars made today are not designed to pull trailers,especially front wheel drive cars.. Anything bigger ,then you have the tail wagging the dog thing going down the road...I have spent the last thirty years driving and hauling and welding on big trucks and equipment, and I say you better listen to what they are telling you, they are not picking on you, but trying to help......just my 1/2 cents worth.....If you see me running for no apparent reason, try to keep up:"Reality" What a concept!Miller Big 40 {1972} vintage, with 150 ft. of 000 leads, old Alaskan pipline welder.
Reply:I think this design is poor in it's concept and I would not personally not use it it may get someone hurt even killed, I think you go back to the engineering table, just my .02.good luck'wbolden
