Use a hex collet block in the mill vice. Set yer depth for one side of the nut. Cut, turn block, repeat. If you dont have a hex block, you can use a rotary table and mill a flat ever 60 degrees. Hope this helps

It all depends on the material you are cutting. If you are doing a lot with stainless steels, tool steel, or other hard materials, then you might wanna think about dropping some money on some carbide. BUT, if you are cutting everything else, stick with HSS. GRIND every time, and hone the cutting...

Gettin pressed about getting an arbor press? Well as far as broaching goes, that all depends on the throat size of the press vs. the length of broach, broach horn, and part being broached. So think of the largest thing you would possibly broach, look up the broach sizes (key seat cutting I think...

Dave, Thanks for the info!! I'm gonna work on sanding till my fingers are nubs! :) Looking forward to the rest of the build!!!

Beautiful work.....your finishes are amazing....how do you get such a fresh clean finish on all your parts? whats yer secret??

Hello All!! Just thinkin the other day after drilling some small thru holes in a slot that is recessed on both sides. Well like we all know when you drill thru, you get a burr on exit side of the hole. Since these are .050" holes in a slot that is only .100" wide, how do you deburr the drilled...

I'm with Dave!

Chipped tooth? If its an old die, is the lead worn? Other wise got me!! Lemme know how it goes :)

Thats super slick....one ups the sliding valve design in simplicity!

Well looking at the video, I agree with the other guys, but you need to seperate the chuck from its mating plate and indicate off a machined surface....for example, the bore of the plate and the machined face of the plate. You are indicating off of what looks like a cast or rough machined chuck...

It all depends on how hard it is. I cut hardened material all the time at work with carbide and ceramic inserts. Do you know what the Rc is on the gear? Also go slow and feel out the material....when in doubt slow it down!

Awesome!! :)

Awesome!!! Thanks for all the info guys! Time to put it to some use :)

So... maybe you guys can clear this up for me. Why does the piece have to spin (lathe) or broach spin(mill) in order for the rotary broach to work? Ive broached at work with a standard hex broach before, but that was just in a press and that defiantly wasn't spinning. Couldn't you just press in...

Great minds think alike! I came up with something similar....and works like a charm!!! Except yer drawings are sweet and mine were on a bar napkin ;)
