Aluminium casting at home - Custom intake manifold

[@richardschofield2201]

I normally stop watching videos where the KZbinr doesn't explain what they are doing pretty quick, but no explanation is needed here. The editing speaks for itself.

[@t.r.8386]

Bravo, congrats from Croatia. I was Tomos rider 30-35 years ago and side intake was my favorite. My last Tomos project was CTX and it was powerfull like hell

[@Rich77UK]

Well done. Super impressive result with a simple set up. One small piece of advice though. Have a vent at the far end from your inlet. Gas and some material can fill these meaning no air pockets in your casting and a smoother pour/flow. Either way I'm very envious of the skill and ability shown!

[@Tomology]

Thanks! Yes, I used a vent in another casting project and it works wonders.

[@dinkoblazek9637]

You have some awesome enginering skills. Keep up the good work! You are one of my favorite youtubers

What a superb job you made there. Brilliant!!

Thank you!

100 points for using a "real" gasket! Not sliming it up with RTV. Yes, you do have the gift :O)

[@johnrobie9694]

That's very cool. I'm so glad I can 3D print aluminum now, because I know I would never go through all this effort.

[@qoph1988]

At that size, you'd sure save a lot of money if you went through the casting effort. 3d printing is like only having a hammer sometimes and seeing nails all around you, but dang it's a great hammer

[@johnrobie9694]

@@qoph1988 That part probably costs $150 3D printed in AlSi10Mg via CraftCloud. I just printed intake manifolds for a v12. Crazy how accessible the technology has become.

[@Tomology]

Aluminium printing is indeed becoming more accessible which is awesome! It might make sense to print it when you only make a single part. Buying all the supplies for the casting adds up quickly and it takes a lot of time. But for me the educational experience was worth the effort. And now I can say I casted aluminium parts in my backyard ;)

[@HectorFabela-k6u]

How different we are as people. I bought a 3D printer and found it to be so much hassle that I sold it and prefer actually making things myself. I would rather tinker in my garage than sit at a computer designing stuff. Funny how we find our happiness.

[@flyerphil7708]

@@johnrobie9694so you didn’t make it yourself then. You paid someone to do it for you. Not what this is about.

[@danielboughton3624]

That was a most excellent result. One thing for the new players - do not mix your grinder disks for aluminum and steel. This risks a thermite reaction.

[@rdyam]

Beautiful work 👍

[@AJVAN_]

I've broken numerous intake manifold necks like that.... the only way I fixed it was when I made one from steel. Cast aluminium simply isn't for this type of parts. But if it' reliable in this form I'm happy for you bud!

[@Tomology]

It still works ;)

[@NathanLeMarbe]

It's all in the engineering. Thickness of material type matters, ask any guy haha

[@eCitizen1]

I'm still trying to process exactly how you did that so well. How you made the plug for the center. Thanks for sharing.

[@Tomology]

I 3D modeled the intake in CAD software and then used that model to create a hollow mold. The center 'plug' is made with compressed oil casting sand. When releasing the mold carefully, the sand is the exact shape of the center of the intake manifold. The outside mold is also made from oil casting sand. All sand molds together form the exact shape of the 3D modeled manifold out of air. The air is then replaced with the molten aluminium and it becomes an almost perfect part when it's cooled down. Thank you for watching!

[@bobg3034]

Great job!

[@Tomology]

thanks!

[@raducumilea-is2yi]

I think it helps doing a raiser...the cavity gets faster filled and the air ecapes true the raiser. 🙂

[@Tomology]

It sure does. For this small part an air hole at the end would be good enough, but I forgot to add one ;) Still ended up nice though!

[@RustyInventions-wz6ir]

Interesting. Nice work

[@kcraig51]

Homemade is always better than store bought.

[@gwheyduke]

Very nice work, good video. Especially considering the improvised casting furnace! 👍Was the original manifold made of plastic or rubber?

[@Tomology]

Thanks! This is a custom designed manifold for this bike. I 3d printed a plastic prototype.

[@lotuselanplus2s]

That aluminium looks to be very low melting point. I've casted a few parts years ago but trying to get my hands on the correct casting sand is a problem. Probably have to import some.

[@sanjeetgill448]

Is that a red coloured mud? You use for casting

[@Tomology]

it's called oil casting sand. it's a specific type of sand/oil mix for metal casting

[@chikokishi7030]

[@d.j.9961]

He Bro, I am definitely new to your channel!!! I stumbled across the video where you smelted aluminum to forge a intake for your Tomos! I purchased a Tomos at a road side sale in a nearby town, got it home & really did nothing with it until 1 day I started looking at it & realized that there is no ID tag or, vin tag or anything! I am unaware if they have to be titled & plated or what? I looked up the engine & it has the bigger engine! The oil line was disconnected so, must run pre-mix which, I have never done! My Yamaha had a oil container & oil injection so, I never had to pre-mix it. I took the carb apart to see IF it needed cleaned but, it looked okay so, I cleaned it then suddenly, I had to move! The carb & parts are stored beside it, offsite at a storage place. How much oil do I need to mix per gall of gas? CAN THEY BE DRIVEN ON THE STREET IN OHIO? If I need to register it, I really don't know how to proceed? It's missing a peddle! & the side skirts, it's all white & black, mostly white with white mag wheels.

[@Tomology]

oil premix is usually 1:50 ratio. I don't know anything about rules in the US but in the Netherlands it has to be registered and insured

[@t.r.8386]

Premixing is better, 2% of oil, but use fully synthetic two stroke oil

[@aliasmari]

👍👍👍

[@pdrhodes68]

Impressive. Totally should get your face in the video and discuss the experience. There’s not many people that can do that.

[@Tomology]

Thanks. I will stick to faceless videos though!

[@qoph1988]

How's the casting holding up? Still holding that big carb out on a long lever like that? Love the route you went with the barbecue chimney and the hair dryer, that's sick lol

[@Tomology]

It's still in good condition. I have to say I haven't ridden it much but the carb was on there all the time while sitting in the garage.

[@nabman5619]

That is spectacular from everything you used was economical, and you didn't spend 100s of dollars on equipment. Just plain old barb-e-q coal and stove.

Salut c'est quoi la poudre blanche que tu met et la matière marron car je viens de tomber sur tes vidéo et vu que j'ai pas mal dalu je cherche à faire des pièces avec

the white powder is magnesium silicate or known as talc powder. I use oil casting sand

[@Tomology]

No, it's just compressed oil sand

@@Tomology it will keep it in place. Now it can move sag and ruin your cast

@@therealspixycat good tip, thanks!

[@therealspixycat]

@@Tomology thanks. I saw guys in Pakistan using this technique.

[@therealspixycat]

​@Tomology also use a support raster underneath the first sand form. I am sure you need only half of the sand. Can you reuse the sand after casting? I still want to try this also one day

[@xeemis]

Was really cool at first but then i started feeling like i was at the dentist.

[@Tomology]

I can make you some aluminium teeth 👀

[@RalphDOnise-vh2cv]

How you keep core central

[@Tomology]

Watch at 5:58. I designed a rectangle shape in the core mold and in the outer mold. The rectangle shape keeps it in place.

[@roehle9962]

Nice one :) why did you cast the part instead of making it from steel tubing?

[@Tomology]

cause it's a nice skill to learn and it's a satisfying process. it's also funny watching peoples reactions when I tell them I make aluminium parts in the backyard xD
