Help using angle grinder/chop saw?

[Bowen Shaner]

Is anyone with metal working knowledge going to be in the lab this week during open hours? If so would you be willing to help me cut eight slices (10 cuts) out of a bicycle with an angle grinder/chop saw? I am a novice so I am unsure which is the better tool for the job. The pieces would come out of the top and down tubes of a steel (though possibly CRMO) bicycle. Any help would be greatly appreciated.

I am a first-time, guest heatsync user and a senior in high school. My project (in brief) is to make a collapsible bike by slicing these pieces out, inserting rubber plugs (with holes at the center), and using a ratcheting strap to pull everything back together. The bike could then be tensioned or slackened by adjusting the strap. It is inspired by this design project that I believe died in 2010:

Hey Bowen!

I just met you as you came in. Sorry I couldnt help at that moment, I was kind of busy. If you come back some other time I can help you out, or clear you on a cutting wheel. I'll be in the lab tomorrow (saturday).

Fantastic, I will drop by in about an hour (2ish). Thanks!

Wait! I am not at the lab yet. Can you come by later than 2?

Sorry, that was my bad. I forgot I had the times in the first post and misunderstood. What time would be best? I am free the rest of the day.

How about 5? Does that work?

Also, do you know what kind of metal your bike is?

5 should be great. I am fairly sure it is steel or a steel alloy.

I'd avoid the 4" grinders, 4-1/2" has become the standard, so the 4" wheels are a little harder to find.  I've got a 4" Makita that I like a lot, but when (if) it ever dies, I'm replacing it with a 4-1/2"

cheers,

You'll find angle grinders anywhere power tools are sold. Larger grinders are available, but the popular 4-in. and 4-1/2 in. grinders are the right size for most tasks. You can buy very inexpensive angle grinders, but for frequent use or for demanding jobs like cutting stucco or cement, I’d recommend spending a little more for a grinder with a more powerful motor.
