How to diamond cut a motorcycle engine by hand

[@mustbescud]

Will you need some sort of metal sealant/protector to prevent rust on the exposed metal now?

[@ThrashTestDummies]

Great question. If you are doing it on metals like brass or aluminum, there will be no worry of rust. However, if you did it on say chromed steel for instance, you'd need to rechrome the metal. I did have an idea that I may try at some point that I thought would be cool. That is to engrave through chrome into raw steel, and then using cold blue to blue the engraving. That would be a nice look I think. And since chrome cannot be cold blued it would only turn the engraved areas black while adding rust prevention.

A high heat clear coat should work fine

"Yes I did paint it, no I don't care". Amen brother, that sure did make me chuckle. All the best for 2021 from New Zealand.

Nice job brother, love from Pakistan ...

Thanks for the support man!

What speed did you use regularly?

Thank you for your videos. I Live in Louisiana also. So many beautiful back roads here

[@ThrashTestDummies]

If you and your husband ever find yourself around the Livingston Parish area let me know! Maybe we can all meet up and ride! I am glad you like my videos! I don't focus on quantity so I don't upload every day with random nonsense. Instead I choose to focus on quality. That way my viewers can actually take something away from the videos I am putting out. Thanks for watching and supporting the channel!

@ThrashTestDummies I will send yall a message if we ever get to Livingston Parish, as we don't live far. We live in Ascension parish 4 miles from Fred's on the River

[@eazyridin7283]

So if you’re doing the motor your gonna need a bigger bit n probably map out the cuts . What do you recommend?

[@Pw.papa.7]

That’s pretty cool thanks for showing us

[@nathanackerman1155]

Do different bits make it shine different in light or look different the cut

[@nathanackerman1155]

And powder coat first : or cut then. Powder coat and powder coat clear ?? Guess powder coat heads cut then powder coat clear bake look awesome

How to prevent cuts from rusting?

[@ThrashTestDummies]

The fins are aluminum and won't rust.

[@justinlong977]

I found the heads on a 96ci are softer aluminum than the cylinders. Once my bit got to the fins below the head it does cut into it as easy. fun project though

[@ThrashTestDummies]

The Harley heads are a different type of aluminum than the cylinders, so that is why one was easier. But as long as you take your time it is certainly doable. Thanks for watching! I'd love to see some pics of your final result!

Good Video........Subscribed

[@larry1861]

How come you didn't back cut the diamond cut , the other guy says you supposed to back cut them is that correct ,?

[@ThrashTestDummies]

I'm not sure what other guy you mean. When I made this video I couldn't find another video on it. But you certainly could if you wanted. You could use round or cylinder bits, stagger the cuts, space the cuts, double cut, back cut, etc.. I plan to make an updated version of this to show other ways to do it. I just didn't get too far into it on this one because I didn't expect it to get so many views. Lol

[@lologuzman1919]

What's the name of the bit you used? And size? And thanks for the video nice work.

[@ThrashTestDummies]

Thanks for watching! Glad you enjoyed my content! As for the bit, you can use a round or straight bur bit of at least 1/8 diameter for the best results. They are just standard dremel bits.

[@michaelbrinks8089]

I heard doing this to cylinder fins & head fins will actually help with cooling...It's supposed to create more surface area & air flow turbulence... Anybody know if this is a fact? I could see it possibly helping when riding but not sitting still.

[@ThrashTestDummies]

I've heard the same thing. I think it's more of a selling point for the companies to do it though. It does create more surface area but I can't see it substantially changing the engine temperature. I could be wrong though. But I would like to see the data after testing.

[@michaelbrinks8089]

@@ThrashTestDummies Just had an idea, to do this to the fins on an aluminum heat sink on a computer CPU and see if it runs any cooler....If it made a noticeable difference in cooling then it'd probably do the same on a engine...I'll never get around to it though. I have a little cheap 2 stroke motorized bike engine. I might dremel the stock head for practice & see if I notice any difference.

What kind of paint you used? I’m wanting to diamond cut my motorcycle frame then have it chrome

[@ThrashTestDummies]

In this video I just used vht low gloss black. But you can do it over powder coat or any other coating that will show a contrast between the color and the cut metal.

[@alstone5257]

Nice, looks good

[@robertkarigan9686]

What size bit did you use for diamond cutting?

[@ThrashTestDummies]

I believe this one is 1/8 inch

where i m can buying the bits an drill

It is not a drill. It is a dremel. You can get them at any hardware store, walmart, online, etc..

[@danamuloin8582]

What about rust

[@ThrashTestDummies]

It's aluminum...

[@danamuloin8582]

@@ThrashTestDummies Your right my mistake,but what about oxidation and how can you clean that up

[@ThrashTestDummies]

@@danamuloin8582 generally speaking it wont really oxidize if you clean it regularly. However, It is one of those things where it is more of form over function. So it will dull out sooner or later. I do plan on doing a review on various products that take oxidation off of aluminum parts that cannot be polished soon though. Not just for content but also because I am genuinely curious.

[@azarelthecreator7098]

The real diamond cuts are done on 2 angles which creates the diamond spackle.

[@ThrashTestDummies]

That's cool. This is another way to do it. For guys at home who don't have access to $20k equipment.
