advice for a noobie chainsaw user

damn, thats a long bar . your gonna cut the planet in half with one slip

 

are you 100% sure it is made from tool steel, there are other steels (like silver steel) that can be machined first and then heat treated to harden and temper.

 

best way to find out is to try to file it (not a diamond flie), if a flie cuts it, it can be drilled, if the file skips across and does not cut then its too hard to drill.

I tried drilling it, it ate my drill bits, a diamond dremel bit and a few other drilling tools

I would be surprised if it were D2 - that is an air hardening tool steel like M2. Grinding on it is not any fun. Most bars are 4100 series steels. That bar might have been made with 5100 series, which adds vanadium; a common practice since the 60's on lorrie leaf springs. It would make it significantly harder than 4100, but not raise the costs considerably. 4100 can get to an HRc of 55 at most, usually in the 40's. 5160 can see up to 60 RC on that scale. I have a made a few bowie knives with 5160(and some folks wonder why I feel comfortable contouring pop up pistons by hand).

 

 

Forgot to add - I do have a knife made of D2 with a 5" blade. I have to use a W2 file to contour it before I sharpen it.

It's what the engineer trying to drill it said

yer.. its hradened then...whatever its made from is debatable, but it dont get the holes in does it..

 

i would just get it cut out professionaly, spark errode or cnc plasma cut..

Like I said Spark it will take 10 mins on that thickness . Problem would be finding a tank big enough ( for the dilectric fluid ) to take the bar !

It's being plasma cut, he doesn't have a spark eroder I don't think

no one local to you have a cnc plasma cutter?

that would do it too.

edit doh... done it again lols

Even better !

I was told he couldn't do the oil holes though, they apparently need drilling with some special bits?
