SolidWorks is an hard program to learn...

Spaghetti maker?

:lol:

No more rise in my japanese engine :)


Tonight I made a little keyway in the crank, which corresponds to the ones I did in the eccentric.

A male cutter, one must have ...

Important to buckle without moving it!

Finished setup.

That did it! The track is 5.01 mm wide and 43.5 mm long.
Easy to forget compensation for the shaft shall be grinded then when you set the depth.

Thats cool.

I love this thread. I bought a cheap mill and lathe a while back and taught myself in hopes of doing something like this one day. It's good to see how it really gets done though.

Just for fun... :)

so when can we see a 26b kit from you ;)

In this speed, about 2025? :)

Crusher of dreams :lol:

One dream at time :)
First my dream, then yours :)

Today I made a decision... and ordered some material... :)

typical me... :S

Wait, what.

What what? :) Wacka wacka?!

What material did you order?

Tegheim if you don't finish this project (I don't care if it's 5-10yrs from now) i will hunt you down.

I like where this is going.

Got an big piece yesterday...

Are you friggin milling your own rotors??

Holy shit!

Wow! :bowdown:

how much will they weigh?

I aim at less than 3800-3900grams complete with bearing and gear. It's maybe not very light, but it's my own, and I could easy do some changes and do one more if somethings goes bad.

Aluminium would be very nice, but I know to little about it, and don't wanna take the chance :)

well heavier rotors may give you more torque. right?

That's actually pretty light.

S4 are ~4500
S5 are ~4300

They would take more power and time to spin up though, so any torque gains would be lost.
Ryan

I would say its very light! But FWIW shouldn´t we talk about moment of inertia? Surely its big difference when the weight is in the middle or on the periphery of rotor? Maybe its not applicable in this example:blush5:

No, not even remotely. If anything than it would be less torque.

Its just combustion pressure, rotor face area and effective distance covered during expansion what creates torque minus mechanical losses.

Today the E-shaft was left to it first grinding-session. Feels strange :)

I should add that I am not entirely alone in this with billet rotors.
My friend Gustav and I often get yelled at for talking more with each other, then our partner's when we are sitting with headsets and drawing SolidWorks at night:)
We have our visions. I want my 4rotor, and Gustav wants his "tired" 770hk 13B will go a bit better:)

Ok, now I have seen it all.

You are basically building your own, from scratch, 4 rotor engine.

Next time my parents go to Sweden to visit family, I'm going with them to come check out all this madness.

I you going to use a oil pan or are you going to go dry sump?

this project is far more hardcore than i.

It's gonna be a dry-sump. I'm about to design my own dry-sump-cover at the moment. Will try to do as Mazda did and keep the pump into the front cover instead of havin a external pump with belts. More about that later on :)

Added the primary-port. If you don't want to PP...

Can't wait for updates Tegheim!

A little useless update :)

This is the start of my 4 billet-rotors :)

http://i815.photobucket.com/albums/z...d/IMAG0857.jpg

That is Awesome!

RE: Image of center iron

Is that going to be a multi-piece iron?

Yes, the plates/irons are multi-piece-design. More info will come later :)

Whutttttttttttttttttttt....

In this thread there is no such thing as uselss updates.
