Journey to the Baja 1000 - Episode 6 - Spindle Madness

in this episode of the journey to the baja 1000 we're taking the used brakes and hub from the chevy silverado and making custom spindles for the j-10 race truck [Music] you're watching the journey to the baja [Music] 1000 okay let's talk about the next part as you can see here i'm already kind of mocking up how the lower suspension arm is going to go but what i really need to know next is what is it connecting to on the other end the dimensions of the spindles so let's go ahead and take a look in this video on how i went ahead and made the other spindles for this truck okay now that the plasma table is going i'm ready to start cutting some parts and i would really like to start cutting the a arms and so this thing starts coming together but i have to know what those are connected to so i kind of have to start at the extremes my fixed uh dimensions which in this case will be the spindles once i have that thing designed and put together then i'll know how long to make the a-arms and then i can change those at the chassis side let's go ahead and take a look at what i'm doing with the design and maybe as i got the parts together how it's slightly changing the way i'm going to build this spindle so here is the necessary evil anytime that you're trying to do a build like this you've got to clean the old parts and i will take the time to really give a good scrubbing all the parts and it's to turn out the brake calipers once they cleaned up i didn't even have to repaint them because the paint underneath is some kind of baked on coating so i was going to leave it the way it is but i also like just to see if there's any damage or something like that you really can't tell that unless you clean all the parts off are there leaks or anything like that in this case the calipers were good and then once you get all the parts together then it's really just a matter of measuring them and then trying to connect the dots and make them fit together into whatever new part you're making let's see how i connect the dots on these spindles all right let's check out the spindle the old spindle from the chevy silverado the lower suspension arm mounted way down here i'm planning on mounting it somewhere about the center of the hub basically to give myself more clearance uh just based on this the suspension geometry so i'm not using the spindle i'm going to chuck most of it i still want to use the bearing i still want to use the brakes as i build my own spindle if you can't tell the distance here is about two inches and the distance on the inside is about an inch so i need about one inch of a spacer off of this i could either cut quarter inch plate and stack it but what i'm going to give it a shot here is i'm going to see if i can't cut this completely apart the spindle in the the band saw and then turn it on its side weld the bottom flange to a piece of metal that i can then chuck it in my other band saw and cut it if i had a lathe i would turn it down that would be the easiest thing to do or some kind of a cnc mill that'd be the easiest thing to do i don't have those things so we'll do the best with what we got let's see how it goes okay so here i go again with band saws i love band size they just work so well and i think the thing that i find and nobody told me this before just so what i found after using them is that the difference between a band saw and like a circular like a cold saw or something that you might use is just that they resist building up heat the saw there's just so many more teeth going through the part and they don't build up heat and you i've i've got other circular saws in abrasion saws they build heat and then just stall out the blade and the band saw just keeps grinding through so there's this band saw and i got the other big band saw which i'll show you these in a second this is a milwaukee band saw i have it in a swag um mount that holds the band saw and then i'm using a foot pedal and i'll put a link in the description for all those things if you're interested in getting something like this so the trick when you're using just a band saw or something like that is and you're making a very specific part is how do you chuck the thing in the tool you're going to cut because it's going to put a lot of torque on that part you just can't grab it right at the very end so what i'm doing is i'm welding a piece of 4x4 scrap steel that i had um to the part and then that will allow me to chuck the 4x4 in the saw and then i'll be able to slice the rest of that part off without it you know flying off of the the saw okay if you were not a believer of the band side before you probably will be now of all the circular saws i've had nothing can do what this saw can do i've got the 4x4 that i've welded onto the spacer chucked into the saw and then now i'm running some coolant as i cut through this thing and it just slices perfectly everything off the spacer that i didn't want at the end of it the blade was fine i'm still using it today it is just such a great saw and it is just so durable totally worth the price i'll have again a link for this thing in the description below cool this is my favorite part of a budget build i started out with that part on the right and i ended up with that spacer on the left and all it took was a little bit of my own time and also some wear on my tools that being said now i have a spacer that fits exactly where i need it to as i start making my new spindle the price was exactly right free and i'd have to take wait any time for somebody to make this part deliver it to me okay it is tough to design things without having all the parts so i finally have the parts together i have the spacer that i made off of the old spindle finally got the brakes cleaned up and they look good enough and then i just mocked up really quickly a really simple bracket that will hold the um the rod and at the other side or the uniball and what i can see my original plan was to run the brake totally vertical and also to rotate this such that the bolts uh were going to be split in between the um the quarter inch plates of the spindle but as you can see there'll be some interference by the mounting bracket of the the break so what i'm having to do is offset a little bit i still get the same plan that i wanted with the uniball uh in the middle i just have to orange it slightly different and make it to where just this quarter inch plate will just clear the bottom of that bracket i can still i can grind off some of that if i have some clearance problems but you can kind of see how this will go together it won't be completely symmetric like i had planned so there's a little bit of a trick when it comes to putting things into cad but if you just break it down into its basic elements it just isn't that difficult first i just got all the dimensions off of all the parts the brakes that little spacer that goes onto the hub and then all also the dimensions of the uniball and then i from there i also have the dimensions of the wheel so this is like the uh inside of the wheel that everything's got to fit inside of and then this line right here is the brake disc which also everything's got to kind of fit around that too and then these holes right here represent the holes of the brake caliper and of course they've got to go on here some way but what you really have to remember is that the brake caliper really only rotates in relation to the center of the wheel so i just okay let me put two holes in there and anchor them in relation to the center of the wheel and now i can rotate those until i figure out how the brake caliper is going to go in there same thing with the the hub these four holes right here are part of the hub but again they just rotate in relation to the center of the uh the will then i have some vertical plates which is going to be where the um the uniballs are going to mount so now i just got to kind of maneuver those around inside of cad until i have no interference with bolts and and all those kinds of things and other considerations i need to think about is i want to keep that caliper as much as vertical as i possibly can because of course calipers have bleeders on the top and i want to be able to orient that and i want it at the back of the the the spindle because i want it to be protected by the lower suspension arm from any rocks and those kinds of things so there are some other constraints here also but what i did is i was able to find out that if i rotated the caliper backwards about eight degrees and then i also rotated this hub about 21 degrees then bolt holes line up and clear and i make this this bracket here then all the holes are gonna they'll they'll be cleared so that i will be able to put the thing together and take it apart while you know once i put it all together which is you know it wouldn't be a good idea to put a bolt hole somewhere where you can't get to it later on when you're trying to assemble the part so so i got the template printed off of fusion 360. i'm going to use this cool cutter here go ahead and just cut it out sure is a lot cheaper to have this thing cut out of paper and check it now as opposed to quarter inch plate still i think it's gonna look pretty good now i got the piece of paper in there you can see all the dimensions work pretty good i'm going to take a little bit out here in the program before i cut the the final plate then also i'm going to do some dimension check some dimensions and see where my steering rod is going to land up here because if i can i will extend this plate out and just make that a as a part of the backing there to give some more rigidity to that part but overall i think it's going to look pretty good so here's what i love about fusion 360. now you can see the parts you're going to be making before you start cutting them out so um this is the one part i haven't shown you yet this is the uh the spindle upright this is a quarter inch plate it's 16 inches from the lower uniball to the upper uniball and you can see this kick out here a little bit and that is where it is going to clear the rim the tire and and everything it will be boxed in on the front and the back but just that's what it'll look like right now here's the plate that holds everything together this is where it mounts to that spacer that we made earlier here's the brake mount uh and it clears those bolts right there and then this kick out right here this is for where the uh the steering is going to be mounted i'll go ahead and brace that thing really good so we don't rip the steering off let's go ahead and put this thing uh through langmeyer assist through the fusion 360s manufacturing program and then we'll drop it into the langmeyer systems cnc plasma table and cut these parts out and get them going so here is the langmeyer systems crossfire pro plasma cutter just going to work on this quarter inch plate and of course i have this sped up but it just goes to work on it and you can see i don't have a lot of waste because i'm able to nest those parts close together and then it just cuts down the time i'm sitting with my hands my pocket while i'm watching what i'm watching for while it's cutting is i'm trying to see if any of the parts when they fall out of the sheet if they tip up and maybe will strike the plasma cutter as it goes around now there is logic in the plasma cutter you can kind of watch it that as it cuts something if it thinks that there's a possibility that part will tip up it will maneuver the cutter around it and it does a pretty good job but man just some awesome parts just coming straight out the machine [Music] [Music] [Music] [Music] so of course it has you know i got all the parts together some of the plans change and that just happens it's got to be flexible as you make the plan but in the ultimate goal is just to get just a gnarly suspension with tons of travel and no interference and and i think this is looking pretty good i'm pretty happy with it and the ultimate goal is to just get a vehicle that can roll under its own power to the start of the baja 1000 and everything after that's gravy i think these parts are looking pretty good we're ready to start preparing them getting them into the weld shop so i think the spindles are looking awesome all right we're going to end this part of it right here and we're going to pick it up on part two of the spindle build where i'm going to show you what i think you're really going to be interested in is how do i take now the mill scale off of that plate still and get it ready to weld and i think you're really getting impressed on how easy it is and again it's a budget build how cheap it is to get all that stuff ready to go i'll see you
