13B Rotary Drift Trike Custom Frame Build!

[Music] we're still waiting on engine parts for the 2j mower so that means it's uh drift trike time again so we'll start with the front end um i'll get this engine up higher and then kind of figure out where i want the forks to mount but the first step is going to be making a steering tube like this that accepts the same bearings and everything that's not aluminum because i do not want to have to make the whole chassis out of aluminum take some measurements find a piece of steel and then go to town on the lathe [Music] so i went looking around and i found a piece that is larger in diameter than these races and that's this giant hunk of solid stock weighs probably like 40 pounds uh and obviously to bore out a chunk the size of this whole stem and then turn down the outside pour out the inside the pairing races that would take approximately all day my thought is i'm going to make two end pieces for the bearing race and then i'll use this one inch or inch and a half 120 wall tubing for the middle part because it doesn't need any sort of raises or anything it just goes you know over this shaft which is much smaller in diameter and i'll bore them to just this size and press them onto the shaft weld them on and then i'll put it back in the lathe and bore them out so that they're more accurate that way because obviously welding stuff tends to warp it so we call this monster the loud loud for obvious reasons but it is well worth it yeah so this is a piece of what i don't know two inch diameter solid two and a quarter solid stock so uh here we go loud loud look at that butter like freaking butter [Music] well i just spent most of the day making uh a really time-consuming dumbbell the steering column thing is uh is more or less done i got the bearing races in there got the two caps welded onto the uh middle piece now um bearings go in there like that and uh time to see if it works so this goes on here fits nice onto that bearing and then this goes right like that oh yeah that's nice [Music] we're gonna take a quick break by the donor car of this operation to talk about the sponsor of this video cove audio and specifically the commuter 2. now this speaker has super long battery life we jam in the garage all day with it it connects to your phone over bluetooth it's super simple and best of all splits in two you got two different speakers surround sound in the garage and they get super loud check this out [Music] pretty rad now cove is doing a special offer for you guys while supplies last just go to covadio.com grind 68 and you'll save 68 on the speaker so make sure you click that link in our description use promo code grind 68 definitely check that out now let's get back to rotary trike and now we have the first part of our drift track chassis not really but you know the first part for things to attach to [Music] we had sam pick up this rear subframe from an audi a6 this morning we got the whole setup axles brakes subframe diff all of it and it's actually surprisingly light for what it is it's also got already double a arm suspension which is ideal for what we're doing [Music] the engine spins the wrong way for this diff which is a problem we've run into before when we built the kernel so uh basically the output of this engine spins this way and if you spin this diff that way you're going backward so that's not good which means the easiest solution for that is to flip the diff upside down and of course there's downsides to that but this diff can probably handle way more power than we need to put through it for this application so shouldn't be a [Music] problem [Music] wow [Music] the original subframe is gone and we're working on uh building a new one well actually this is all just placeholders to hold this uh together in exactly the orientation that it should be so we can figure out the new diff mounts and um where everything goes and then we can get this whole assembly in position behind the engine and trans and then start making a chassis that attaches to it [Music] i'm getting ready to make my first uh piece of chassis here i'm gonna make most of it out of inch and a half tubing because uh that's what we have and i think it'll look nice so i'm thinking i'll run one kind of something like this it'll come straight back from the top of the steering column there come over come down and then back and tie into the transmission here with a nice bracket and then i'll also bring in a couple down the bottom of the tube here and then do some trellising here which will look super cool and be super duper strong which is what we need because this thing's beefy time to bust out the rogue fab fender which i haven't used in a minute and which brings me to another point which is we are giving one of these away so head over to our website check out the details every five dollars you spend on merch gets you an entry to win your very own rogue fat bender with this sweet custom grind hard wrap yeah so this is our rogue fab bender we've had it since basically the very beginning of grind hard and it's always worked perfectly and done everything we've needed it to do yeah it's really simple easy to use works great makes nice bends all the things you need from a bender [Music] well i think we got the first piece of chassis uh tacked in place sam's been working on the bracket that'll bolt on here onto the transmission and this piece will end there and then some other tubes will start at that same bracket and go back to the diff so um won't be too long before we have this whole thing connected [Music] well i'm working on tube number two of this chassis and it's a somewhat ambitious uh bend because i've got a bend here here here and then it's going to bend somewhere in here it's going to bend out and then go straight back and tie into these upper a arms right about there so a lot of bends at a lot of different angles to get right and uh getting it right once is one thing but uh you know hopefully i can get it right twice so that they match and for that reason i'm writing down a bunch of random information about every bend on the chassis here so that'll look cool when it's all let's just be the whole thing will just be covered in scribbles [Music] [Applause] [Music] the rotary trike is coming together one tube at a time um this this tube here turned out surprisingly well for having five different bends on a few different planes um took a while to get it fit just right in terms of the notch here up front and the angle at the back and the notch here into this plate that that sam made yesterday this still isn't aligned exactly perfectly uh because i don't have the part to make that bit yet um but there's still a lot of flex in it so we can move it around to get it where it needs to go the one thing i'm not entirely sure about is travel i don't know how far up this axle will come at max suspension travel but probably not pat well obviously it won't come past that because it can't hopefully it won't hit that um but i can always just limit the travel to that because you know that's less than halfway out the axle so you know that that three inches or whatever traveled there would equal like six inches or something at the wheel at the wheel end so it should be okay there so another reason for making this tube all one piece that i haven't mentioned yet is that i'm gonna go with my um frame tube frame rail coolant tube concept again on this build because i don't want the radiator up front it'd be vulnerable and it looks stupid and there's already not much clearance between the tire and the engine um but it needs to be a sizable radiator so probably put it back here behind the seat somewhere and so we need to run the coolant all the way back there and all the way back up to the engine so i'll probably plumb into this frame rail somewhere up here near the water pump then we'll pump the water through it back to the radiator back up the other side and there'll be some weird hose to get it back because both the outlets are on this side but it'll also have the benefit of adding a lot of volume to the cooling system [Music] so [Music] so i've got the electric hydraulic conversion all installed and filled with oil and working and uh it's amazing it's awesome it's so quiet also it's on right now it doesn't make any noise when it's just sitting there and uh it's way faster check this out wow as a bonus the air compressor doesn't take on pop right through and get super noisy so yeah that is so cool so much better enormous upgrade [Music] stop avalanche ghost in the garage ghost of grindheart's past huge upgrade on the bender huge thanks to roguefab for that and for making sweet tools [Music] is that what i think it is uh well i don't know what do you think it is oh a plumbing tool a pipe wrench yes it is today we are using a pipe wrench on a pipe like a real plumber would but you know in this case i was just using it to twist this tube a little bit to get it lined up better [Music] i'm gonna make some brackets here to support the front of the engine off of this part of the frame i mean they'll kind of be supporting each other but i think i'm gonna go to this spacer here uh which is conveniently already there so i can weld to that it uses this alternator bolt onto the water pump and then on this side there's a bracket where the engine hoist point is that's pretty sturdy so [Music] so got some front engine mount brackets done here um i'll probably reinforce them in other ways later but that'll hold it together for now so the next thing is to get the rest of this suspension mounted to something because right now it's uh pretty floppy floppy [Music] [Applause] [Music] [Music] [Applause] so i'm doing a little uh 180 degree bend for uh a little hoop part of the frame and uh just ran this out reset and now i'm on the second reset pretty dang simple run the rain back the way we go to 180 180 degrees bling-bling there'll be a plate that bolts to the original mounting point on the transmission here it'll go to this and then from here there'll be two bars that come back to this other bar for some extra strength and extra mount points for the suspension well uh it's far from complete but i want to see uh how it does on its own weight so we're we're about to find out we've got all the jack stands and uh now i'm gonna lower it and see if uh it falls apart those forks have never had weight like this before nope hey that's not bad i got this hoop welded in last night they're tacked in so now i can make some bars that go from that hoop back to here and tie in with this suspension point and then that'll you know all sorts of other stuff can mount to those tubes and that'll make it way more rigid also right now the back is just being held up by the stiffness of the bushings there's no shocks in there at all so you know that's uh that's sagging a little bit but yeah it's on its own weight it's a drift strike it rolls it's the bare minimum of a rolling chassis you know as we always do testing things way before they're ready that's the floppiest chassis i've ever seen there's that much like we'll see what happens if they just give it a little oh yeah okay so sitting there it's like that we can get significantly stiffer springs for those forks so last night i also got this hoop in and that supports these lower control arms here i've got some brackets tacked onto there and you know so that's holding everything in the right orientation now um i'll eventually make a mount for the diff but uh first i need to make the adapter here and we're waiting on the part for that but because right now you can just move the diff around a little bit because of the flex and then if we unbolted it from this rear plate which this is going away very soon it's just still holding everything together but um once we get this part i can get the diff located with that and nice and straight and then i'll make the mounts for it yeah exciting times we have a rolling chassis of the world's first 13b drift trike also next week we will be back on the 2j mower we're just waiting for one more part to rebuild the engine and then we'll finish rebuilding that get it all in there so never fear we are still working on the mower [Music] [Applause] [Music] you
