Casting DIY Skateboard Trucks At Home - Ep. 3

[@GoodRoads]

I just noticed that I got the term for risers wrong a whole bunch over the course of this vid. The tubes coming up out of the mold that I cut with the brass tube aren't gates or runners, they're risers. Please excuse my amateurish use of casting language hahaha!!!

[@brentmosser1494]

Only if you excuse me for calling you Alex in a comment a few weeks back. Sorry about that. Not sure what I was thinking. I'd be so excited to see your custom board get some exposure on Braille's channel. I'll definitely comment over there that they need to check out Chris from Good Roads.

how to make fingerboard truck

[@snowboardik]

Pivot cup, kingpin hole and mounting holes are drilled/milled after casting on a majority of trucks. No need of trying to cast this elements at all.

[@fredkennedy8435]

haha, "I am not a patient man," says the man who's building his own skateboards from scratch.

[@trickswithjp]

As a foundry worker (I don't make molds just smelt iron) I daydream about trying this almost daily. Just the thought of grinding concrete curbs on homemade trucks is kinda badass

[@GoodRoads]

Iron work is so sick though, if you've already got that experience you're half way there

Since you used old router metal. Route Trucks has a good ring to it! Dude, this is so awesome.

[@GoodRoads]

Hmmm, I like it!

[@tinayoga8844]

To keep the sand for the pivot cup in place, put a nail in it. The nail will add support to the sand. Also use more parting compound on the inside of the pattern. Use a fine hair (artist) brush to paint the parting compound on the more vertical surfaces.

[@GoodRoads]

Thank you! I will give this a shot next time around

[@TurboSqu1d]

I'm in the process of making a custom electric longboard and considered this as an option to get just the right size of hanger I needed. I searched everywhere to find this kind of video and nothing came up but went through your backlog of videos after finding your custom wheel videos, remembering the project in its infancy ages ago. I did end up finding a product that I purchased at a good price but this is definitely bookmarked for future projects. Very cool and informative video otherwise.

[@GoodRoads]

Thanks dude! I also searched for a video like this for many many years and didn't have any luck. That's a big part of why I tackled the project, I wanted to get this information out there

[@adambee4575]

Fantastic Chris, you made trucky truck trucks - excellent work. Braille would be awesome too!

[@nirodha7028]

Bear Trucks use that hole pattern. Works well. Man! What an awesome outcome to this project man! If you make more: add a logo ;-)

[@GoodRoads]

Yeah. I knew there was no way somebody out there wasn't drilling their baseplates like that, it just makes too much sense. And yes on the logo!

[@nirodha7028]

@@GoodRoads Will be watching progress with great pleasure my man! You are doing awesome work. What I was wondering is the cost effectiveness of this process. Other than being able to create custom geometry... is it economically viable to create for example a small production run to sell with proffit? The way I see it you are totally set up to sell complete custom boards at ‘custom board’ prices. Pretty sure there are folks willing to fork a sum that makes it viable as a bussiness model. Would you agree? I know you are sharing all your files for those willing to invest the time and effort themselves... which is great by the way! But your personal experience and time is certainly worth money to those who cant be bothered to get hands on. I am personally working on quad skate plates which are UFS inline boot compatible and the truck geometry is totally custom. I designed them with casting in mind but the prototypes are being milled atm (I have a friend). Interested to learn the economics of this process (cost of sand? Reusable? Gas? Other consumables?) and if you have ideas on how to scale up? Perhaps a tree with multiple parts in one go? In that case another method is needed to capture the shapes (lost wax or lost 3D print moulding) but yeah... Looking forward to more sir!

[@GoodRoads]

I am certainly not thinking about production level truck manufacturing at this point, I was just compelled to do it for the sake of having done it, but it might be worthwhile at some point to look at the numbers. I honestly think sourcing and processing the right kind of aluminum would be the biggest bottleneck. The rest is pretty straightforward and there aren't many recurring costs. It's just time consuming

[@michaeljohn8905]

Nice ! China can’t seem to make INDYS axle and hangers straight. I’m a lifelong independent rider and now I’m going to change. Yours look much nice. Good job man. I’ll be watching more of your vids. Keep it up

[@omni5129]

So with the axles .. they usually cast in a dummy rod, made from sand and resin, the resin burns away and you are left with just sand .. that's the reason why you see the axle showing through in 3 spots, as those spots hold the resin rod straight .. the casting is then heat treated to T6 ... then the axle is pushed in as heating the axles will soften the metal. The other holes for pivots etc are just left blank and drilled later.

[@GoodRoads]

Hm. Yes. I know some of those words. Hahaha! In all seriousness: thanks for the tips, that all seems like super helpful advice.

[@jiproijackers7595]

Perseverance pays off. Well done Chris!

[@raistnox]

you might want to try an oil bonded sand, might get a better surface texture. also for your pivot cup issue take a look into sodium silicate sand casting

[@GoodRoads]

I got a tip to add some neutral oil to my sand which I want to try, any thoughts on that?

Well done, WELL DONE!!!! Innovation in anything comes from people like you that are doing it for the absolute joy of doing. Not driven buy money and greed. Also the baseplate wheel base option holes is brilliant.

[@jesterblackguarde8464]

A good way to shape your pivot cup would be to use a ceramic core. Same thing for any semi-complex holes. Put the cores in place on the bucks, and pack the sand around them to hold them in place.

[@GoodRoads]

That seems like a viable solution, how do you make those inserts?

[@andrewschryer8131]

With the sand not releasing off the buck what about a different mold release agent

[@timort2260]

Damn that's pretty cool. They came out pretty dang well.

[@DIYToPen]

One thing to consider, if youre trying to drive away moisture with a propane torch... propane breaks down into water. Most of it will evaporate from the heat, but you are effectively spraying the part with water.

[@joshlawton4973]

[@quinnfoster4671]

[@BootlegHuman]

Like the NightHawkInLight but for Boards, love it

[@JohnQ84]

So I know I'm a bit late but about the Axel if you spray the casting down with cold water right after pouring it would re harden the steel inside the aluminum plus less waiting but it's that long slow cooling equals soft steel

[@Biokemist-o3k]

Wow!! This whole series is super cool. I am starting a KZbin channel soon with a build of a 1928 Morgan MG special Brooklands hillclimb racer.

[@darrentyler1817]

Friggin amazing!! I wonder if you drilled a few holes in the axle, cross ways, if that hole would be filled with aluminum prevent axle slippage?

[@GoodRoads]

I think drilled holes would cause a weak point but there are a lot of factory made axles out there that have some kind of knurling on them to prevent slippage, I'd like to figure out how to make that happen

[@erich1394]

@@GoodRoads I wonder if you could use a vice or hydraulic press (harbor freight has cheap ones based on bottle jacks) to remove the axle after casting and replace it with a new axle that hasn't been exposed to heat? You could potentially make the casting axle slightly smaller than the final axle to achieve a very solid press fit. I know nothing about whether this would just tear apart the aluminum or if it would slide... maybe there's some sort of metal-on-metal casting release agent that could help with this?

[@GoodRoads]

Interesting idea

[@KrakenCasting]

That's so clever, printing a support to use under the cope! I don't have any experience with green sand, but Petrobond can get you a really clean finish. Also, maybe try looking into casting with zamak, it's a zinc/aluminum alloy that's pretty tough, but it has a lower melting temperature. The lower temp might get you a better finish.

[@Dodgeram1500hd]

When you are doing reverse kingpin trucks there is a locker washer usually square that slides into position this is what holds an anchors the kingpin in place. The entire barrel of the bottom base plate is threaded to the top the kingpin itself should have enough depth to reach the bottom of the locker washer with 5 mm sticking past the lock washer while the truck is medium tight this allows for people to ride loose and still have enough thread on the locker or nylon ring for it to keep the kingpin stable because it is easy for a reverse kingpin truck to back out the kingpin. For reference use grind King they are the best

[@brunoraffo6726]

GREAT JOB!! Did you know the Fury trucks with "ballpoint" pivot? I thought was interesting enough. Good luck!

[@thomaslindroos1667]

[@mojoejojo171]

Maybe try a reverse kingpin ?

[@GoodRoads]

I'd love to do that at some point

[@dhruvgoel2202]

To prevent sand from falling during removal of the part add much more of the powder on the part before putting sand to make mold. Also you can add a little amount of water in sand to increase moisture content to raise the adhesiveness between particles of sand. Also tap multiple times on the part such that it moves walls of soil all around it making it easier for mold to be removed without damaging the walls of the mold.

[@GoodRoads]

Thank you, I'll try this next time around

[@AnttiBrax]

BTW, axles on mass produced trucks have knurling to prevent axle slip. Edit: Oh yeah. You definitely WIN.

[@GoodRoads]

Yes. I definitely want to figure out knurling at some point

[@erich1394]

Regarding the open bushing seat - if you've ever ridden Paris RKP trucks, that's the stereotypical loose bushing seat feel. Amongst other things, I notice a softer endpoint to the truck's range of motion... like you could push them a little further even once you've hit the end of the range, whereas a more restrictive bushing seat can feel like there's a more authoritative / blocking endpoint. I also notice that less energy gets lost in the turn on open bushing seats when carving quickly (or pumping). I wonder if the open bushing seat combined with the progressive turning from your TKP design would make this newest creation a good front truck for a pumping board?

[@inktrooper.]

AWESOME! That was faster than I expected. About the pivot cup issue, I think you can taper the walls of the cup open a little, but I think you'll end up needing to finish the cup with a round-tip drill-bit. I mean making the form of the opening of the cup, but not as deep and marking the point on a flat surface with a some sort of a little cone for drilling. Or even make the wider part of the opening of the cup the size of the final pivot cup and taper it down a good 5° (for an easier release) all the way to the final depth; this way you could easily shave the excess with the drill to get the final shape. Also I recommend you clamp your jig to the drill press plate, I know you were anxious to finish them so you could ride them, but we can't afford you losing a finger ;) (knock on wood).

[@GoodRoads]

Thanks dude, I noticed when i was shooting the b-roll that it looks like the pivot cups on the Indys are actually drilled or machined or something. Definitely a detail to keep in mind going forward

[@inktrooper.]

@@GoodRoads Yeah, man. While you were typing that reply I was editing my comment to give some ideas. Ok, I just dissmounted a couple of my trucks and the pivot cups have drill bit markings, which tell me they were finished on a drill press. And I just found a 90s video of the venture factory where it's shown the pivot cups are drilled on a press. kzbin.info/www/bejne/l4bPdJ9olpmtq9k

This is sick dude, good find! You can get a quick look at their runners and gates on the hangers too and I like the idea of using a single plate to form both the cope and the drag

[@minnow11]

Just came across your channel for the first time and I have a suggestion! Try putting a little bit of silicon metal into the aluminum when melting. Mix it up after a little bit then fully melt it and it should flow better.

[@leradicideglialberi]

AMAZING!!! Really amazing!

[@paulojrg]

My suggestion for the pivot bushing hole is to just create a centre point with the whole diameter and with the same angle as the drilling bit and drill the hole later and the same goes to the bolt holes. Follow the K.I.S.S. method of designing parts.

[@GoodRoads]

I People have been sending me a lot of factory videos and it certainly looks like all those features are drilled after the fact using cast-in-place registration marks. I may very well go that way next time, it's probably a heck of a lot easier

[@paulojrg]

@@GoodRoads Try that it may seem more after work but the rate of successful parts is worth it.

[@anglegrinder4630]

Is not pressurizing when fitting the axle into the hanger mold a problem for strength outcome?

[@AB_Pyrotechnic]

to fix the pivot cup issue, put a piece of all-thread in cup as support. think of it like rebar in concrete. if all-thread doesn't work, just a normal course thread wood screw works! make sure to heat the screw very hot before use though. sometimes hardware has wax or oils that will burn off. they will add bubbles to your part or ruin the mold.

I'm not clear on what you're asking in the first part of your comment, the board rolls straight if that's what you mean. As far as a reusable mold for aluminum I've seen steel and graphite molds, and I imagine there are probably some ceramic solutions out there too. You could probably mill a graphite mold with a hobby level CNC, it's not a very hard material. If there are any other reusable mold materials out there I'd love to know because that would be fantastic.

To be honest, for the holes.. if you have a 3D printer, just print a support, cast a Pilothole, and drill the Kingpinhole in the hanger and the baseplate afterwards. I do have a CNC mill, that will greatly assist me in doing that kind of work.. I also like the 8 hole baseplate for wheelbase adjustment.. i've never seen that.. and i think it's cool! Since you can make these Jigs for making the mould with a 3D printer, Go Crazy, and design your own trucks, with a shape that everyone will recognize!.I have made a 3D Design (available on GrabCad) of the Bennet Vector trucks, copy the geometry, and design a less cubic shape.. :)

[@shadowcard6923]

Do not fully cast RKP baseplates, as the kingpin really does need a press fit (can be done with a vise) but, using a core you could potentially cast the holes by making a core that makes the face that the bushing sits against

[@GoodRoads]

False! And I'm only contradicting you to get some historical information out there, so I appreciate where you're coming from. Some of the older RKP geometries, specifically the Randall I and II's had a friction fit on their kingpins. That's not to say a press fit isn't better, it is. But you can totally rock a RKP setup that just has a standard bolt as a kingpin, it was done that way for years before the tech evolved to what it is today

Thanks for sharing! My favorite part is getting to see your sense of accomplishment. I'd be feeling giddy too. You made all the important parts of a skateboard that can't be borrowed from other pre-existing industries. FUCKING AWESOME! Every truck I've taken apart appears to have a drilled out (post molding) pivot cup recess. Perhaps a pilot hole for that as well as one for the kingpin would be a clever adjustment to your baseplate buck, along with the jigs to angle the molded baseplate under the drill press for the proper angles, and some method to stop the drill at the proper depth.... masking tape around the drill bit comes to mind, but fancy drill presses have adjustable stops.
