As an experienced machinest, i can attest to the nightmare of learning how to set up everything correctly for rigid tapping. My first time was absolutely brutal, but you learn what needs to be done after a while. Here are crucial tips. The biggest thing you NEED to watch out for when tapping a blind hole is tap selection. Never use a spiral point, or even a straight tap when doing this. And if you do use them, make sure to drill almost half an inch deeper so the chips dont build up and break the tap. But the correct choice when tapping a blind hole is ALWAYS a machine tap. The flutes are designed to pull the chips out of the hole. Secondly use as much coolant as possible. Taps simply just break without the lubrication and cooling of good coolant. Third. Always check and make sure that your drill and tap are spinning perfectly true. Ive had it be off a bit because i was using a busted tool holder. Fourth. When programing the code. Always put the M03 Sxxx, in the line immediately above the G84 line. Some machines simply wont understand that what you are trying to do is rigid tapping.

I'm just taking my first CNC course so you obviously have more experience, but when going over rigid tapping on a Haas mill we were told specifically not to put the M03 code in with the speed because it will override the change in spindle rotation that is automatically in the G84 code? Would the exact rigid tapping parameters be specific to particular makes/models of machine? Otherwise thanks for the good tips, I'll be rigid tapping a part next week and I'm definitely a bit nervous about breaking the tool off, especially because it's on the smaller side (1/4-20).

Tip for the future dowel hole machining: You may want to opt for a smaller diameter endmill, with a less flutes and higher rake for chip clearance. Pre-drill with a twist drill (%50 final dia) for more chip clearance (peck drill) to reduce face milling with the tool and tool % engagement Use the smaller endmill to then helical plunge rough cut to within .025-.050 the final diameter Follow with a semi-finishing pass (dia -.010) on the same endmill or one with more flutes (more rigid) Reamer plunge cut to final diameter. Other misc: possibly modify the circular interpolation to get rid of some of the "faceting" you see on the larger complex curves. This may/may not affect seals, but could change how a bushing wears because of stress points. Looks good!

@adrianfinkler6913 9 ай бұрын

Well, maybe i'm thinking too much about machining speed, but i'd get a modular or indexable drill, because it's way faster and usually very straight and reliable, also with the precision. Of course, they are expensive and it depends on a lot of parameters, but if he really want's to produce a lot of them, then they would certainly be worth it.

A 5-axis mill could make a complete iron in 2 setups no problem (less finishing operations like the tungsten spray). A 4th axis in the current mill might do it if all the oil passages are parallel and at an angle that’s also compatible with finishing the ports.

For a blind hole, machine taps are far better. Spiral taps push the chip into the hole. Machine taps pull them out of it.

@michaelfust9520 9 ай бұрын

As you build these, you will continue to improve processes. My old timer recommendation is to finish as much of the insignificant items as possible first. That way all the precision machining doesn't get scrapped for something menial. Easy to hard not hard to easy. Better to scrap a pice with minimal hours than one with maximum hours. Separate programs. Center bearing AND locating dowels need to be separate options to allow for proper sizing of each individually. You can rough everything in one shot.

@M_Gargantua 9 ай бұрын

For the blind holes into the fixture plate, for v2 you can make a thicker fixture plate with chip evacuation channels and a hose attachment to flood coolant into it from underneeth, so once the hole is punched into the fixture channel the flooding coolant carries them away. Reduces the risk of ruining the hole due to a failure to evacuate chips. Only worth setting up if you're going to do a bunch, as it requires a lot of refixturing to drill the coolant spray holes and manifold for the hose to feed into.

Its awesome what you have done and are doing to keep the rotary alive. Its always been my favorite engine and was the very first car engine I rebuilt on my own when I was a kid lol.

Awesome to see rob, im halfway through my apprenticeship in cnc machinist and this is the type of stuff i dream of! Also….you dont have enough water in your coolant, check your mixtures as too much oil in the coolant will give you problems 😊

Kenametal makes a great tap for your application. I work in a CNC shop, something I noticed was your speed when tapping. Slow that bad boy down brother! Keep up the good work

It’s unbelievable how far you’ve come Rob. So unbelievably proud of you brother

I'd recommend using roll taps. They form the threads by pushing the material instead of cutting the thread in This results in a stronger thread as the grain on the metal ain't cut, it's just reformed. If you do end up roll tapping just remember that your drill size = diameter of the tap - 1/2 of the pitch ( instead of subtracting the full pitch when thread cutting)

Y’all are an incredible team. Very talented. This group reminds me a lot of the B is for Build team. A mad scientist and a great fabricator put their minds together. And also the work ethic is crazy. Y’all dont seem to stop🤘

Man, if you had told me way back when you and Jaret were making weird skits in the garage in Michigan, or videos about how games get guns wrong, that you would be CNC machining your own engine one day a few years later I would have bet you everything I had that it would never happen. It's amazing how far you've come and I can't wait until the day this thing fires up and screams to life for the first time.

I've always ALWAYS wanted to do this... I've got a pretty massive CNC... and it cuts aluminum no prob, but I want to actually take the aluminum from soda cans my family drinks recycle it, alloy it in my smelter, and then pour it and cut it into shape. Really happy for you, cutting engine parts is a huge milestone. 😊

I want to see Rob build a half size version of the 12 rotor. Imagine a transverse 6 rotor mounted in the back of a car it would be sick. This 4 rotor is going to be great I can't wait to see what's next

have you ever seen rob smile soo much in 1 video other than when the engine first started and when it did its first proper drift

It's so awesome to have watched your full journey. From your 3rotor, to all aspects of the 4rotor and corvette. Well both corsets and the indy can and everything in between. Your killin it bro.

When are we gonna see the 12-rotor content, will it be called a 78b or something different because of the rotor layout?

I watch this work and it fills be with happiness, that the engine lives on. Hopefully one day there will be more affordable options for housing and plate replacement for our engines, especially since the price of the Mazda keg has doubled.

@Jared45513 9 ай бұрын

So cool man. After watching this whole time seeing all you do with the rotary, ive learned a lot. I bet a lot of people would buy an engine from you. I machined for a few years, any time i ever rigid tapped allum. I slowed the speed /feed down at least 40% of what you were running and used the largest possible drill size to get the thread engagement you need. Also used the cnc to start blind tapped holes, only maby .300, then its perfect square and then the rest is finished by hand in deburr. The spring loaded holders were easier, they give up and down play so when the tap gets a hard spot or hung up slightly the machine cant break it.

so excited to see where this goes. been waiting for you to make the leap into producing your own stuff. designing all your improvements into your own billet stuff. weird being proud of strangers lol

@raturn0 9 ай бұрын

so beefy oil cooler and pump to keep oil flow high and overall engine temps low enough to keep the alloy from delaminating?

@Hippida 9 ай бұрын

WHen you actually have the resources you have, not to mention the enthusiasm, I find it so fitting you use that know how to further expand on how you can make this engine, perhaps, even better. Best of luck for this project. Can't wait to see where you end up with this

Came such a long way Rob, gonna be watching the development of the new rotary build/Dahm built Engine process. Such a crazy time we are living in and I’m all in for it! Wondering how far you can take it, rotary swaps are going to be the new Ls swap, mark my word!!

@Mr.Bearded.Mechanic 9 ай бұрын

For blind holes, it is good to use a drill with inner cooling chambers that can push out the chips from the hole. There are multiple types of it, simple twist type, changeable tip type, and changeable insert type. The insert types you do not even have to pull out after every certain depth cut.
