How to quarter a brake rotor?

[GromitInWA]

I have a couple of brake rotors that I took off my car and would like to make something like this bookend.

What do you guys recommend for neatly quartering the rotor?

A plasma cutter would probably a good choice. perhaps a metal cutting bandsaw.

I would not use a used rotor. Besides the mess aspect, rotors develop hard spots which makes them hard to machine.

A new rotor could easily be cut into quarters with a band saw.

Thanks. Just saw a YouTube video of someone using a plasma cutter to cut one in half, so looks like that's the way to go.

Interesting. Thanks for the advice!

Cut off wheel in a 9" right angle grinder, or if you can figure out a way to clamp it in an abrasive chop saw

Band saw is the eaiest and cleanest. I've done it both ways. Band saw runs right thru them. On the side note, trying to clean them up with a grinding wheel does not work very good. Best thing is to get a clean cut with the band saw and not have to spend 2 hours trying to make them nice and neat with a grinder.

It all depends on what you have access to. As long as you have a steady hand you can go with any of the above-mentioned methods.

Personally, I like plasma cutters but if you are free handing it then there is more room for errors. the cutoff wheel (larger the better) is more accurate but will take longer.

i have a brand new cross drilled and slotted rotor from a toyota tundra i can set you up with. i only have one

 

[APEowner]

A band saw goes right through them. If your patient I bet you could even cut them with a hacksaw.

Wire edm. Stack them and do both at the same time.

Hey Pmech, is there anything you don't
know ?

I'm lazy. I would take it to the water jet place and have it done for 20 bucks in 5 min.

Bandsaw, I've done it before for someone that was making furniture. They cut surprisingly easy for what they are. Touch up the edges on a the belt sander.

As AP Mech mentioned, best to use new parts for industrial art, especially when the component in question is a cheap brake rotor. Otherwise a good long soak in the parts washer is in order.

Bandsaw or EDM would be the best ways.

No band saw, no plasma...........sawsall with a quality metal cutting blade clean up with a disk.

 

[Techie1961]

Cast iron will dull a bandsaw blade really quick, especially a used rotor, and they aren't cheap to replace. A few hack saw blades are cheap and it won't take much time. Zip wheel on an angle grinder would be my go to tool or like Showkey says, a sawsall. Sawsall blades ain't cheap either though.

Take the vise off of a 14" chop saw and use it. Quick, and a nice clean cut. Mike

I would use this:

Doesn't everyone have one of these?????
