Default Re: what did you do to your motorized bicycle today?

I guess technically this is working on the bike... I didn't do anything to the actual bike today, but I'm still learning my new CNC and I cut my first successful copper exhaust gasket earlier today... You can see the difference between the first and second one I cut as it's pretty obvious... I had to reduce the feed speed and use a different type of end mill and then the second one I cut came out the way I wanted it to. I'll cut more of them when I get up in the morning now that I got the cut settings where they need to be... These are .030" thick, but the ones I'll be installing and selling will be .120" thick so they'll conform better to the mating surfaces...

You can see in this picture I made this one a little bigger so I won't have to trim it after I'm done porting this jug... The final product will be closer to the exact size, but with enough room to remove about 1mm from each side of the port and the same added clearance top and bottom.
