How to Build a Rat Rod Chassis (rat rod build part 2)

what's up boys and girls welcome back to the hardcore fab shop on today's video I'm gonna get started on the rat rod project in the last video you guys seen me gather up some of the parts and pieces that I've got laying back here but I thought on this one I'm gonna show you guys a little bit more in depth on what it is exactly that my plans are here before I get started doing some of this work so let's check it out just a little bit closer so I've got this thing sitting on the ground just like I wanted to look when it's parked all the way down rockers touching the ground got the front axle kind of pushed out there a little bit so that we can go all the way down to the ground and still have that big block sitting in there my trash can there is representing the big block it actually majors you have to be pretty close to about the same height there's a big block with a stock pan on it so that'll kind of give you an idea if it has a total ram where the telegram sits of course we're gonna have a carburetor in there and that scoop would come up just a little bit higher if I use that scoop I'm gonna have to build a custom chassis for it of course I think I'm gonna go ahead and do a cantilevered airbag front-end suspension going on there on the front so kind of been working through that in my head a little bit and of course the only way to do it is to have those big giant nasty slicks on the back and I've got them positioned pretty close to about where I want the rear end to sit so I did pick up a Ford nine-inch while I was out there gotta go through that bad boy but no big deal there and it's gonna stay in there real close to where those stars are out like I said so the bed is going to be pretty short as well because we don't want the bed hanging way back far off the back of the truck so this bed side that I got is kind of already all hacked and whacked up the one on the other side is actually a pretty decent bed side I've got so much to junk over there I can't really show it to you guys but anyways both of them are pretty straight across the top so the top rails are in pretty good shape and of course I've got that tailgate that I had to begin with so I think I can make that tailgate and these bed sides work together with the rear end that I've got and actually make this thing look pretty decent the side rails with the little curve in them right there at the top is probably gonna have to go over the top of the tire instead of being down inside there but I think that will actually look better anyways and when it's all said and done I can build a cool roll pan or something for it and kind of tie everything all back together in the back of course the back gets four linked and air bag back there as well and that should make this thing handle and drive out pretty damn decent of course to be able to get that big block through there we're gonna have to take that firewall out that's gonna have to all go away and a good section of the floor I got that light sitting there so you guys can see the rust is actually pretty bad in the front section there it's a little worse than what I was thinking it was out there but it's still something I can work with the back section of the floor underneath the seat is in a lot better shape so we might be able to save some of that and then just do a tunnel through the middle of it oh that's gonna have to come into play after I get the motor sitting in the frame and we see exactly what it is that we got deal with at that point that kind of gives you guys an idea of what got going on there now I'm excited to get working on it okay so I'm gonna be successful and putting all these parts and pieces together then I need to come up with a game plan here so what I've done I started drawing up some stuff on the CAD program let me show you guys what I've got to start with I drew out the cab I've got a rough kind of general shape here of what it is and it's got all the important numbers matching in the right spots as far as this height then it's a link here and everything forgive the crudeness of the rest of it but it doesn't need to be anything special for this drawing now if you look down here I've got these rectangles with some angles on the stuff actually starting to represent the frame rails those will be square tubing and then I've got some gussets drew up that will plate that in on the sides and I've got them out back here for the four link bars to hook up to in the back and I went ahead and put in the representation of the tire here and the back as far as its size and the location of the brackets on the rear end that'll give us a just ability there to make this thing right out and perform pretty good on the front you can see that I've got a drawing here of possibly what the front we'll end up looking like as far as a cantilever arm for the air ride system on the front right now I've got this thing sitting about 4 inches off of the ground ground represented by this square that 4 inches is gonna be the right height of this thing when it's run them down the road and that's gonna be when this bag right here will be flat and even and that's where we'll see it most of the time at ride height okay so with that that gives you guys an idea of and me an idea of what it is that we're doing on some frame rails so I think it's time to actually go cut some metal and start putting this thing together I'll spare you guys all the hours are cutting and grinding to get to this point just show you the finished product on the frame rails they are a 4 by a two-box square tubing it is kind of a mixture between 3/16 and eighth wall just because that's what I was able to source right now but everything is boxed and welded all together and fish plated so there shouldn't be any issues with any strength or anything they're designed these brackets to go along with this frame rail before it's been made so they fit together real nice and it should add a lot of strength to that Z right there in the frame and that buzzer was my front door opening and it was my buddy Marco he'd come in to see what was going on and hang out in the shop found out that I was doing a little bit of welding and stuff and wanted to jump right in he's a pipeline welder and his off work right now and as with most guys that are good at their profession they want to stay in the rhythm of stuff so he wanted to jump right in and get started welding awesome stuff with me and I'm game for that because when you got a couple people working on something that makes things go away way easier usually a lot easier set everything up and hold everything in place and with him welcome on one end and me cutting and grounding on the other end things happen pretty quick so now with the frame pretty well done I've got to figure out how to get the cab over onto the chassis and get it stuck down so I've been looking at it a little bit and I've got a pretty good idea how to do that let me show you guys what I'm thinking I've got to say if you guys got a forklift this is definitely the way to approach this thing so you can get a little better look at it underneath this thing it's pretty well a clean shot right through the front of it there down the side of that rocker there was one spot here where I had to take out just a little bit but I found some four inch square tubing that's gonna lay in right through here I said square tubing angle iron there's gonna laying right through here and then come back over and then touch on the floor of the cab where all the mounts are at there's a mount there that one all needs to be pretty well redone but the other mounts that are in through here can't see them very good but they're all in pretty good shape everything's gonna lay within that piece of angle iron and it's gonna give me a support down through here on the side of this rocker so that when we do drop it to the ground it'll be hanging just a hair lower and that being just a little bit lower is gonna save the whole bottom of the door because there's no rock or anything on the bottom of that door so if we drop that down and it lands kind of on a rock or brick or something right there it's gonna damage the door now that angle line is actually gonna save us and it'll give us a good place to be able to attach the body and then attach to the frame after another day's worth of work of fitting those pieces of angle iron there Neath the bottom the cab and get them all bolted up I weld them together where they couldn't move anywhere and got them slid over on to the frame and made some mounts up again so those will still be going in but I've totally got to get everything all sitting all in place first before I can make sure those are in the exact right spot where they need to be real quick before I wrap this video up I want to tell you guys thank you from the bottom of my heart it means a lot to me that you guys sit here and watch these videos take the time out of your day I know there's tons of other things you could be doing but it truly just really does mean a lot to me that you guys do watch them and if you guys have any suggestions on anything that I can do better or change or if you've got any ideas on something for a video in the future or something like that please feel free to hit me up in the comments down below and let me know what you got well I think that's all I got for you guys today hope you guys enjoyed it and I'll be back to working on this thing in the next video [Music]
