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.

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

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

Living the dream. I have long fantasized about opening skate shops in third world cities that presses casts and thaned everything in house so the don't have to import parts. Very well done.

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.

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.

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.

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

I've been wanting to do this same project and how cray , KZread through you up on my recommended list randomly. Loved your journey man. Great story, work and process. Cheers Bro!

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 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!

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

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

Incredible :)

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.

you are awesome, sir

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.. :)

Next time you set your axles in make sure that you have drilled holes in the axles about 30 mm apart throughout the mid span of the truck axle. This will allow the casting material to go through the holes locking the axle in place preventing axle slip

I think I'm going to try to go the knurling route, but some feature to lock the axles in place is definitely a good idea

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.

In a parallel universe this is how they fabricate illicit skateboards in the Khyber Pass.

Way to go bro that is a accomplishment in its self making trucks this was really cool, also your ollies are decent for any trick you want to learn 180* popshuvits etc just practice makes perfect. 😎🤘 need to get some grinds in your ollies are high enough for a nice fun box to practice and learn 😁

@@GoodRoads not something I'm familiar with, worth a small scale test at the very least.

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?

4:00 sodium silicate is the solution :)

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.

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).
