Question about Cutting a crank or cam shaft.

[Reebz]

I pulled a camshaft and crank from a scrap pile of a repair shop. It most be to to some big *** diesel motor its like 4' long and thick. I want to use them to make a tv stand.
The question is are cams, cranks a super hardened steel?
Is an ordinary bandsaw blade what I should use?
I put the cam on my Elis 1600 and it cut extremely slow. I did not leave it on very long because I don't want to screw up a fairly fresh bandsaw blade.
Thanks Have a Great Thanksgiving

You should not have a problem cutting a crankshaft with a bimetal bandsaw blade. It is most likely 1045. If you really are that concerned you can always use a cut disc.

There is a possibility that the bearing journals on the crank and cam are induction hardened. Depending on the engine manufacturer. Cam lobes too.

Thanks guys. I did not give the saw much time to work. It just seemed "different".

Start a groove with a grinder, then use your bandsaw.

i wouldnt put it in a saw. id take a $3 zip wheel, use a 3rd of it in 1 minute, and ur finished and it cost u $1. a abrasive cutoff wheel hardly notices anything hard , it just cuts it. a saw blade cost many times more than a zip wheel. i dont like putting oddball shaped stuff in saws, or something that makes little surface contact in jaws, cuz it might come loose/spin, i screwed up enough blades doing it. a tv, naw, there bad foir u, better for a potted plant or somthin

I've had stuff spin in the saw. Sucks.

I know that a brand new Bi-metal sawzall blade was no match for a 2 stroke Suzuki outboard crankshaft.

I just needed the splined end off the crankshaft from an old seized (badly enough that I couldn't remove the crank via normal methods) parts motor so the machine shop could have a test piece to verify the spline he was cutting on a gearcase mod fit properly. Couldn't fit a cut off wheel in more than 1/3 of the depth, sawzall was only thing that would fit. Ended up having to use a diamond blade made for cutting cast iron.

If that's the case with your crank, the damage is probably already done to the blade. Doesn't take long. Cut off wheel is the only way to go for that sort of thing.
