Tegheim - Home made 4 rotor Wolvo 142

Tegheim · 11-30-2013, 11:12 AM

The build continues.
Bought standard lock rings, but couldn't let them be standard.
Grinded them from 2.5 and 3mm with friendly tolerance to 2.00mm

The it was time for the grooves. Did them +0.03 to +0.05mm in height to get the right feeling. They are easy to install, and sits solid when released.

Have modified an old front bearing for test.

A keyway as well.

First of all I'm very proud to annouce this link

Back on topic.
Builded some new benches to work on, and then started to assembly the dummy again to put back in the car for some measurements.

Tonight I was out on the highway and meet a friendly truckdriver from Czech Republic. He had brought a 20B flexplate from hIGGI on the Rx7Club-forum. Thanks alot for that hIGGi!

Also got some V-band-clamps today. Perfect size. Small and tight, just like we want them.

Bought some Ø10.0mm Chromemoly 4340-bars.
Cut them in correct lenght and cnc-turned M10x1 thread in both ends.
I use Grade 10-nuts and harderned washers to hold the engine in place.

Todays work was the peripheralport-sleeves.
Cut some Ø80mm alu and threaded them M65x2.

Next step is to machine the rotorhousings.

Yesterday I continued with my Peripheral-inserts.
Because they are threaded into the housings there is imported to get the D-shape in the right angle to align with the pre-machined D-shape in the housings.
The D-shape closest to the housing are bigger than the round hole and the runners, so therefore I need to machine this with the inserts on the side.

I could have done a round hole in the center, and port the sleeves by hand. But I'm really not a "handyman"

And CNC-port are in my opinion the coolest.

It worked out pretty well! I was really nervous when I mounted the first insert...

I very satisfied.

Next is to deside how to couple the inserts with the runners, and also how my runners will look like, size and lenght. Butterfly-throttles or slides.
