POTD- PROJECT OF THE DAY: What Did You Make In Your Shop Today?

[rwm]

Hi, I've never seen this nor do I understand what or why this method is used.

It's cheaper than buying and arbor press and Dumont broach set? I think that's the only reason. Well, that was my reason.

Was referring to the angle that seems it weakens the rod.

I made a keyway broach, to cut a slot in an aluminum pulley I machined for my lathe.
3/8" 1018 round bar and a 3/8" locking collar.

Yes, very interesting. Is the printout your notes or do you have a link to the source?

Thanks, Charlie

Got it. I suppose it is to get clearance for the cutter. Yes, you could grind in a clearance angle and have the tool straight but you would have to grind down a long section of the cutter. As long as the keyway actually.

Is this is where we remind everyone of the biggest idiot on the internet who broke the crap out of his mill doing an idiot thing because he was an idiot? Not exactly broaching, but the shoe fits:

I did it on the lathe using light cuts. Worked perfectly.

Trying to decide if I should use my mill or the tailstock on my lathe.
