Dont know a thing about rotarys. This video does an amazing job building and showing how complex/ simple these little motors are!! 10/10 great freaking job man!!!
Having been a Machinist since 1970: 1) your running that reamer 1.5-2 times as fast as it should for that operation. 2) Never ream without either water based or oil based lubricant if you want a true sized hole. Less lube needed with a carbide reamer, but still needed. You probably should have put that bench-top vertical mill in back gear for reaming to slow it down, remember to reverse directions while in back gear.
Thank you for Tip . I am cnc Machinist I love advice🙏🔥
I’ve never been into rotaries until my brother bought a FC3S. Now i’m obsessed and love them! Still don’t know everything about them but i’m continuing to learn! Loved this vid.
My son has RX-8 and we watch your videos all the time. The knowledge you share with people unbelievable my son and I truly appreciate it. Thanks
I’m a third generation holden mechanic by trade, and I’ve never been into rotaries until now, but I’m thinking I wanna build one.
Would you recommend always putting Vaseline on your shaft before you put it in the hole ? Ha ha ha great video Thanks very much
I love when people share their skills. Much appreciated man 👍. I'd totally have u work on my engine, but I'm in the states 😡
Well done Broomy. Awesome build mate.
Hey guys. I am a Toolmaker and I do lots of those type of machining. I see when you tap and ream you use slow movements to not over heat your tool which is right, but may I suggest you use tapping paste when you use reamers and taps and dies. It will totally help with the overheating and helps you not to seize your tool or minimize the risk of breaking the tool in the job. Love your video’s keep it up
Rikus Stipp I use this stuff when I’m cutting reaming drilling and tapping on the mill or lathe www.lenoxtools.com.au/Pages/Product_LenoxProtoolLube.aspx
It'd be great to see how you do the diy stud kit machining process, the m10 threaded stud heads are genius. Getting cnc studs done costs about half as much as a decent china milling machine. There's a thread on Aus rotary about using the centre plate as the template for the rest of the holes but the housings seem to be the hard part due to misalignment of bolt holes. Do u just drill through the centre plate into the housings, not worry about the drill bit walking and let the reamer take care of truing it up?
this really help with little tips and tricks 👍
i really love and obsessed with rotary even i don't have any rotary on my own, and i'm zero about how its work and assemble before. this is amazing video, it make more obsesses with it. feel like want to be your guys to learn and work on it. it my dream to work on rotary. full respect from me in malaysia.
Good job guys. I'm not a Rotor guy, but it was interesting to see how it all works.
Fantastic video
Thanks for this! I would never attempt it myself but it's good to see that there are still people who can... excellent work!
This is a fantastic video. Awesome build.
Thank you very much for the build video I have rebuilt many piston engines never a rotary one but now I have a RX8 I am going to have a go at one got the manual got the engine its have a go time Thanks again Kevin from the UK
Great vid. The details make all the difference.
That’s a really good and easy to follow video, guys!
Wow amazing stuff, thanks for the video!👌
Awesome vid mate... with my limited knowledge of the rotary If I had the time, money and facilities I would have a crack at a a rebuild... excellent video mate well done 🤙🤙🤙🍻
what a beautiful process
finished my s4 about a week ago, should have it running tuesday !!
What set up are you running?
Awesome tutorial! Thank you
I'm surprised you don't machine the combustion faces of the rotors, you would be surprised just how different each combustion chamber is from factory. Also do you ever bother to check the apex springs for resistance, there are many times you will find a certain apex spring is slack/lacks resistance. Just a few tips..👍👍
Nice work.
Very very nice. We are looking
You might find it a bit uncomfortable but it is best to keep your party pack chilled.
All right now seriously you are pulling the case studs up tighter than 48 pound feet/65nm, you did say that you were tightening up to 1/2" unf?
I would also suggest you invest in a center finder or a clock to clock the counter bores of the end iron. A whole lot easier and more accurate.
nice one Broomy !
Did you guys balance the rotors/rotating assembly after the clearincing proces? If not whats the rpm limit of this setup?
very well done
Nice & clean job
Awesome
E&j stuff that my buddy
I've always been told never use vaseline on rubber o-rings because it's petroleum based and slowly eats rubber. Your seals probably aren't rubber though, eh?
Thanks for the vid, I've got a semi-pp (built by someone else). Not planning on building a motor anytime soon... but I've got your vid bookmarked just in case. :)
awsome video!!!!!!!!
Hello sir, i'm enjoying your videos a lot.
I'm curious as how the rotor housing gets resurfaced or honed, well because surely the equipment for honing piston engines cylinder won't do.
Nice,👍
How much material did you remove from the sides of the rotar's
Friction systems should be dealt with in the engine housings... of its pressure, timing, and containment of the combustion system.. and not on the rotary.
Swing, spring, pressure, and timing to contain the forces and energy within the engine housing... which will relieve the pressure that friction is giving on the rotary...
They say a rotary has only 3 moving parts, well all those seals are moving! And there is a lot of them.
Just want to ask why did you go over to fueltech management.. from the microtech??
I didn't see how to put the smaller apex spring in.
Where do you buy those studs? Or is there another company making them like that? I cant find these on Power seals site.
Can you send me the link for the tdc check fixture
Nice video, learned alot. Any way you can do a 20b one day
We will be doing one shortly.
I have a question why did you have like a. Nudge in the housing for the bridge port ?
would a lighter rotor increase the performace?
Internal and external micrometer
You can also just use an old water seal doubled up and slipped around the rotor to keep the apex seals in place. 👍
Fuk yeah
A Peripheral/bridge port engine??
Ghost Port?
Do you have another video of this monster being turned over?
The engine was in our Project Redline.

I've seen on another video that the corner seals actually have to go in the right way up.. one side is machined.. have u guys heard this ?
Andrew Gaulton some brands like Atkins have an up side
@@BackyardMechanics cheers.. thought so.. it's not talked about much
whats up with the breakaway corners on the apex seal??????????????? is that standard or an opstion???????????????
They are like that to make it easier to assemble.
They come from factory like this.

Nice semi PP rotary engine tho
I did NOT know a rotor was hollow like that. 👀
"these are expensive pieces of machinery" *has Pepsi can and plate on said machinery*
A race ready 20b guide now 😂
I think it's pretty much similar, you just add one more rotor and rotor housing.
Is the same process done in 20b just extra rod and plate?
more or less yes.
*_I thought there was no timing in rotor engines?_*
I saw a guy who has a rotor engine and it had a chain, he said something about screw piston engines and there is no timing with the rotor engines._*
I would have asked him how the spark plugs know when to ignite the mixture?
3:24 I am not even a mechanic but shouldn't a higher clearance mean less oil pressure?
It depends entirely on the design goal for the motor and the part choice. Pretend I want to use straight 30 weight instead of a 5-30, and I use a stronger oil pump (more liters or gallons per minute flow rate) to handle the stress of racing.
Using arbitrary numbers: The stock motor has 45PSI on 5 thousandths clearance but I am getting 70 PSI at 5 thousandths with the race-ready upgrade. Because the oil pump can flow more liquid, and the oil is a thicker kind, the pressure is going to increase beyond what the motor was designed for. I may need to increase clearance to 8 thousandths to get oil pressure to the right level. Conversely on a very badly worn out motor the clearances may have increased from 3 to 8 thousandths, and I may want to use a step heavier oil to have oil PSI in spec. It's all relative to how the engine was meant to run and the changes you make to it.
@@TykeMison_ so as in you example, higher clearances will decrease the pressere
@@Runmeerkat Exactly!
Yes but bigger clearances mean more flow better cooling.
So you run high oil pressure regulator to make up the pressure at race rpms
Hay
love fullboost videos....just not a fan of rotary engines ...
Little cold?
No, it's a Semi-PP
!
eczema always think "vaseline"
Noice
Jeez...you could grease up Bronson with that lot! Quicker.....quicker....quicker.... lol
Semi pp
25:58, learnt from last time. ruclips.net/video/sjiYSDZukwQ/видео.html 15:26 I wonder how long that engine lasted? Might look like I'm digging, however I do really want to know. Did you hear about it again?
MV60 learnt from last time ? Do you think the other video was the first I’ve built, and this video is the second ? 😂😂 other engine is still running.
@@BackyardMechanics Pretty obvious it had a seal out on that other build. No need to get snarky, I would really enjoy building one of these under your guidance. Pity we're in different cities. I'm trying to be joking as well as genuine.
As explained 500 times already It was just an oversight in the editing suite using the wrong clip. Obviously if it were left like that the engine would have been toast...
@@fullboost Thanks man. What would have actually happened? I like how you use those stronger apex seals too, really restores faith in that you can have a reliable rotary when you set out with better parts.
Semi PP hahaaaaaa
knows a lot but the dirtiest build, get a washing and oven station those rotors were dirty as dirty pamper
Was this rotary from a mint, 10,000km rx8? Yup, time for a rebuild!
I didnt know that rotary is hallow inside lol
“Tighten that down to ugh-ugh” - that’s exactly how I torque things
I tighten them down till my worn out old elbow clicks.
Please start the dam thing and show us what you got
wonder how far through this video ill get before i just say fuck it, rip out my mild ported 13b and start the process of probably fucking it completely going for a wicked sound and terrible driveability at all the rev ranges it normally gets driven at.....
While some people do use an engine like this on the street, we wouldn't recommend it :)
@@fullboost And i very much dont recommend myself picking a mild port when an extend was right there available to me. live and learn kids.... live and learn.
Forget getting cnc precision with a drill press 😉
White Jennifer Wilson Christopher Lopez David
Get a cat......😉
Wrong
Waaaaaayyyyy to complicated.
A normal engine is just as complex when you really get into it.
@@nismofreak33 Yep, have to deal with timing and cams on a piston engine.
For me piston is allot easier because i have been into it for long.
But rotary is still wonderfull. Unfortunatly we dont have any rotary gurus in my country 😭😭😭
Just do electric. Lol
To avoid all this and the issues that come with it just get yourself a BARRA
It would weigh more than the car :P
@@fullboost Weight means nothing when you have enough torque ;) same goes for revs, don't need 10,000rpm when you got the torque as early as 2000rpm ;) btw you know i love you guys haha
@@fullboost Acts like a weight plate. No lift.
i tried fitting a barra into one of these 626s, the thing hangs over the front bumper when its bashing against the firewall
@@logical_volcel Wow man. There's a yellow rx7 getting around here with a 2j in it. It's really tall in that vehicle. Amazing it fits length wise ok. Quite a fascinating build.
Amazing .....
Would you do an experiment like in this picture for your next project?
8ttps://images4.imagebam.com/9e/b1/2e/MEKFJ3L_o.jpg
I have a heated debated with my friend,
he said without "Gear", the rotor will wobble randomly and erraticly.
I think No, because the rotor is holding by its housing or casing and eccentric shaft firmly/tightly.
I can't prove it, but logically my idea is right, isn't it?
So if you interested in this concept, I would be very appreciate.
Have a nice day
