[The Red Wonder]

What do you guys think...total machine time was about 8 hours for both sets, not too bad. I am super happy with the end result.

Here are the results of the shop day:

Step 1 -

Step 2-

Step 3-

Step 4-

Step 5-

Step 6-

Step 7-

Step 8-

Step 9-

So happy with the results!

DRO for the win!

The levers...ran out of day

The goal:

The brass toe piece was a last minute addition and I think that its sweet!

SUUUPER nice surface finish

One of the knurling wheels wasn't engaged on the second toe piece so it only cut with one, leaving it a swirl pattern which I kind of like a lot, it seems a little more unique than a typical knurl.

Peg -> Brass insert/ lever arm -> bolt on shifter arm -> spacer -> bolt
The spacer presses up against the face of the peg and has a small step the same OD as the bearing surface on the peg so that the shifter can float around nice and free ;D

Super pleased! Thanks for looking!

God, I am so jealous of the skill, the tools & end product. Nicely done dude.

that is definitely one of the main things im looking forward to having access to in college!

just wow...

one day, ill be able to do that. THEN ill wake up upset, that it was only a dream

 

[dcmspikes]

these are far too nice for those bolts.

 

[ohiocaferacer]

NICE!!

Those are gonna look good on a bike.

this is awesome work! couple suggestions based on my own experience, the brass or bronze bushing on the aluminum shaft will be okay as long as it's very clean, which is hard to keep on a bike. try stacking either felt or ptfe (teflon) washers on the sides of it so it's basically sealed, and add a spring washer to the stack to maintain pressure as the sealing washers wear, mcmaster has all that stuff and it should keep those rolling smooth for years

+1 to that
Throw on some 12 sided ferry cap bolts or some socket head bolts. Other than that, absolutely beautiful. Good work, keep it up.

 

[djelliott]

I could do that.........If I wanted too.


All joking aside, very nicely done. It was cool seeing the pictures go from concept to finished project.

Find the shop owner, become his best friend, work for him, learn everything he has to tell you! I probably learned more useful things from these two old guys than a lot of my classes!

Haha, you can do it! Practice practice practice!

NICE!!

Thanks man, I think so too!

Good idea, although there is only about .050" of float from side to side for the lever arm, so not too much room for anything extra but I could probably squeeze some PTFE washers in there. Thanks for the compliment!

Lol...it was what was in the shop's "Ace Hardware" section...definitely not final, just used to hold everything in place. I'll have to find something shiny to match for sure...maybe some brass headed bolts to match the toe pieces.

Thanks! I have gotten in to a habit of drawing "EVERYTHING" out before I make it. It makes it much easier for me to visualize, then make the drawings, then think about how to actually machine the parts, then make them. It doesn't add too much to the overall time, but time that I think is well worth it.
