Look what I made: A quick release from scratch.

Hi there!
I wanted to share a little project of mine, that I am quite a bit proud of.

I am very interested in machining lately. I bought myself a small lathe. And now I am watching abom79, oxtools and Stefan Gotteswinter (whom I met actually in person) on youtube, lusting after their knowledge and equipment.

But to return to the scope of this forum, I am also restoring a very sad looking Klein Pinnacale. It was very much abused, when I got it. Dings and scratches all over the place, badly drilled holes for a Magura brake and no paint left on it!

This is how it looked like, when I got it.



All the parts are scrap, basically. I'll be rescuing the RS1 fork thou.

And I've been reading a lot about the early inventors of the mountainbike scene lately. FTW, Cameron, WTB and the likes. I somewhat got inspired by their way to fabricate their own stuff. Parts, frames, everything. And that fell in line with me trying to learn fabrication and machining. I thought, I might take that battered old Klein in that direction and make it a "Cameron-style self-fabricobbled-together" kind of bike.

With my limited abilities and machinery I picked a part that seemed easy enough and that I wanted to put on the bike. An American Classic quick release. I have one on another bike. A good pattern to look at. And I took some scrap metal I had collected from work and from the scrap metal place nearby.
I spent two (or was it three? :roll: ) afternoons in my basement, measuring, thinking, trying and having a whole lot of fun, actually.
And this is what came out:







This is the "original":


As you may notice, it has a bigger diameter than my version and looks a bit clunkier on that kind of frame.

What do you think?

:D
 
Nice work. A lathe's a great tool, I love mine.

For the lever, I assume you turned it, including its eccentric, and then bent it? Heated and bent, or just bent cold?

How much eccentric, by the way?

@ tufty: On my first attempt of the lever I heated it before bending but it gave me a very ugly rainbow-like coloration on the metal. And I was not able to wirepad it out. So on my second attempt I just cold bent it and it came out well. I have to say, the rod is bored out. I guess that helped.

The excentric part is 0.5mm off centre witch results in 1mm of "movement".

@ Minifreak: Yes, absolutely.
 
Re:

Very nice, If I had more time I could definitely get into doing something similar.
Quick question for all you machinists, I have a set of kingsberry Qr which are pretty much identical to the American classic design pictured above, but the groove where the circlip sits in is worn so that it pings off in use. How would I go about making it good again, presumably to take a smaller circlip, without any specialist tools?
