Thanks guys! I will try to keep the pace now when I feel the flow.
Some days, I just wanna blow the whole shit up in the air :)

Tegheim 07-05-2012 02:33 PM

Today I did a mockup to see that the coilover-lenght could ba about right, and that the angles looks good in the car.
I also got som used rear tires, also to mockup and make sure the fit later.
225/45-17" Front
255/40-17" Rear

I think we all feel that way with a project sometimes. Take a week or so off, have a beer, or two, or three, or.... with guys that are tracking their cars. Run a few laps of Gran Turismo, etc. Bam! good to go, ready for more work. :auto:

I see that you say "four rotor" build. how about some images of the motor build?

Look at the whole thread.

Tegheim 07-06-2012 12:06 AM

You got to have a car to put the engine in. There's alot of time there!

Mazdabater 07-06-2012 12:15 AM

Looking gorgeous as always buddy, do you have the shaft back yet?

Raksj04 07-06-2012 12:31 AM

So how much of this car will you still be able to call a Volvo?

Mazdabater 07-06-2012 12:42 AM

I'm going to assume the badge. Lol

Tegheim 07-06-2012 07:13 AM

On the outside the car will look original, but rather low, about 150mm lower than stock :)
But Volvo have thought about this idea a looong time. This Badge the had on the P1800-model. I think they wanted to say something :)

I recieved a rod yesterday, Delrin, for bushings. My wife is happy with me as I am :) Coming to these using a stainless steel sleeve model 16x2mm.

http://i815.photobucket.com/albums/z...2/IMAG1560.jpg

This is what it would look like, as common.

Then today I got to work hard because I do not have access to laser-cutter. Began to mill as deep as I dared, without them to come off, and the plate begins to vibrate and break the cutter. Then there has been much handwork! Good for me, to practice a bit. Continued on these!

Came up with an new idea about the Camber-adjustment. Simple to adjust with only one tool, and no need for deassembly anything around it.

http://i815.photobucket.com/albums/z...011280x720.jpg

4pc Ø30mm steel.
Did not have the possibility to use the CNC-lathe tonight, so it has been some therapy in the manual lathe.
M20x1.5 thread for streanght and good adjustments.

You are a bad boy holding black steel in the three jaw!!!!

Tegheim 07-18-2012 05:00 PM

Why not? What else could I've done?

Raksj04 07-18-2012 06:03 PM

Could you put something next to those so we can get an idea of how big they are?

Mitchocalypse 07-18-2012 07:30 PM

words cannot describe how impatient i am about this :willy_nilly:

Ofcourse, later :)
They are 90mm long, and the thread is 65mm.
The thread is Ø20mm with 1.5mm pitch (M20x1.5mm)

When I was an apprentice in fitting and turning if I did not use a 4 jaw chuck on anything but "bright" (ground or machined) bar stock I was kicked in the ass :)

NOTE: If it not my machine, and I am in a hurry I too like you abuse a 3 jaw on black steel lol.....

Tegheim 07-19-2012 06:47 AM

Then I'm going out on a limb and say it's bullshit :)
We use 3 jaw in our CNC-lathe, and all of the other manual lathes.
The only reason you want to use an 4jaw, is when to centre something that isn't at centre by it self if you know what I mean. But then we are talking 4jaw invidual.

I have worked in workshop for 10years, and have never heard of that you're saying:)
My "mentor" in lathe, have 25 years of experience, and have never done otherwise either.

You may have right, but they who learn you that, must have ment something else? For what reason?

Tegheim 07-19-2012 11:26 AM

Step1 done, someone asked how big they were, so... Pepsi :)

RICE RACING 07-19-2012 04:25 PM

Cause the parts are not round perfectly and the three jaws tighten on a common scroll/worm what happens is it stresses these, its basic theory, this is why on black steel you never use a three jaw chuck. Every workshop I have ever been in has been the same.

I agree with you and your boss though :) I basically never myself use anything but a 3 jaw :001_005: regardless of it being black or bright bar :icon_tup:

Tegheim 07-20-2012 08:49 AM

Thats maybe what you are going to fabricate. When we have low tolerance on the roundness, we turn the chuck with 3-jaw first, then clamp our parts.
Almost any CNC-lathe I've seen have only 3-jaw-chuck.

Tegheim 07-20-2012 11:43 AM

Have started to modify the A-arms I had for the old setup.

Weld-nuts! Easy made in a manual lathe!

could you make a double wish bone converison kit for the 2nd gen RX-7 please?

Since you can adjust the bolts one at a time, couldn't make some intresting adjustments.

Tegheim 07-22-2012 03:30 AM

A double wishbone on a FC3S isn't easy.
I have bought me an FC this week that will be an Renesis in. Hopefully some things for the track also pop up :)

Tegheim 07-22-2012 08:50 AM

The last piece done.
Just welding the shells on to the wishbone, and som painting.

2 weeks of car-vacation.
Worked out pretty good, 2 sorts to choose between also.
The only thing that doesn't work is my mobile camera :)

afgmoto1978 08-03-2012 09:41 PM

That is a really slick idea.

This weekend I made some of my brackets for suspension. It dropped suddenly and has gone very well. Starting to agree with the TIG-welder, and begin to realize that TIG is for us who can not MIG / MAG :)
It is slow and calm :)

http://i815.photobucket.com/albums/z...2/IMAG1671.jpg

Then weld all as much as possible before it is installed in the car to where also welded into the frame.
The sole purpose of avoiding weld so much in uncomfortable positions :)
http://i815.photobucket.com/albums/z...2/IMAG1672.jpg

Then the most important today :)
I was to pick my crank! Finally!
Now it's just for me to continue with splines etc.. Let the pictures speak for themselves :)

I find it absolutly incredible that you are making most of these componets yourself. In my opinion its people like you who are mostly responsible for keeping the rotary community both alive, and progressing. Thank you sir for your passion.

Tegheim 08-26-2012 07:08 AM

Have some thoughts.
Do not know exactly how to setup my 4 rotor.

I can build a full throttle PP, much power on high rev.
Or perhaps a Semi-PP little more driveability, longer curves?
Or, finally, a complete side-port setup?
Sideport-setup takes som heavy mods on the FD-plates, but nothing is impossible.

I would rather not overcharge, but it might be a possibility together with the side port and low boost.

This first setup will not be a power-setup, it would be a road-legal-version if it's possible.

What do you think?
