Was for a class project, btw...Do bike companies hire industrial engineers with machining experience?

 

[ThePriceSeliger]

I would bet they would hire someone with your history, it sounds like you know what your doing, because I don't know any of that!

 

[GravityFreakTJ]

I don't know any of that!

To many jokes...can't decide...which one......

I don't know anything!

Good work

 

[Denny]

Nice work! From what I hear it's tough to get a job in the industry. But it's all about who you know...

By the way, anybody need a stiffer fork brace for an old Z1?

What program did you use to draw that? Looks good!

Alex,
Interesting portfolio. I went to OSU too. I also do a lot of similar projects at my job. However, finding a job in the bike industry is overrated and under paid.
Just curious, on some of your projects, it seems like you used a wire EDM when you could have simply milled the part. Specifically, the weld jig and the die.

But wire EDM is sooo cool!

Why wouldnt you, if you could?!

Welding jig: needed 0.0002 tolerance...not that easy with the mill, plus needed a good way to cut the two halves apart
Press die: the material was tool steel and quite thick (2+inches If I remember) there would have been way too much tool flex if I used one with a small enough diameter for the corners yet long enough to get to the bottom.

nice job. so does that have all the measurements. could i make my own. if i had all the machining tools and such?

EDM is cool, but it's slow and expensive if you have to send it out. Most places won't have one.
We use lots of tiny tools here at my job. You'd be surprised what you can make a .035 endmill do at 12000 rpm.

I know it, thankfully we have our own. Using tiny endmills is always a fun adventure, but if cutting something harder than aluminum...tools of that size don't last that long, so instead of worrying about replacing a dull/broken tool, I choose the EDM

You could, although not all the data is availible from the drawing picture, you really need the model file.

another IE, eh?

p.s. stay the hell away from my job prospects with that list of skills.
