 Post subject: Shaved the drive face

I used my tst variator face
I was in a rush so I didnt do a before weight
but I did an after weight 3.8 oz


I was going to do my stock face but it has much larger fins, and the tst has smaller fins
so it was less for me to remove

I used a small bolt cutter it snapped the fins off fast

Then I used my bench grinder to do the rest of the work
Image
I also used my angle grinder with grinding wheel to get the majority of the broken fins off, while its spinning on my bench grinder

this is a cool look, this was after using the angle grinder with grinder wheel
Image



then I switched to a flap wheel on my angle grinder to get in closer, smoother
I used a hand file, and forced it against the face to remove the rest of the fins that were still showing
and went back and forth between the flap wheel on the angle grinder and the hand file

as you can see I revealed a pin hole from the casting
you could keep sanding until it goes away, but my luck I would just discover more
Image



Lastly I used couple different grits of sand paper, one was torn off a belt sander
as its thicker will last longer, another was some emory cloth
that also had some thickness

and 500 grit wet dry paper since thats the thinnest it gets hot very quick

Took more time doing the final sanding then it did to remove the fins, I wanted to go slow and take my time

sometimes I would attempt to polish it with polishing compound but since its cast aluminum you could see tiny micro cracks on the surface
I suppose those could be wet sanded out but I only had 1 grit to choose from

In the end I did a raw finish blends in better

bike is turned off
looks like its spinning in the photo

You do have the chance to add any groove lines for looks if you chose to do so
I just wanted flat and smooth

since its out in the open, really dont need fins on there adding weight and drag

its for the look , since you can see it exposed

you dont want to do this if its sealed up inside the cover
