Extreme Screwcutting - Hughes Precision Engineering

[GeneralG1810]

Ah just get a tap and put a shifter on the end of it LOLz

[gaizka1140]

That,s what I do all the TIME . And it is not an extreme enginnering , it is somethihg normal in a workshop. It is bronze material , it is a metric thread , and well You,re not working correctly . It has vibrations and I am sure a bad finish in the thread . Hi from Monterrey , Mexico

[cocksparrows]

rather you than me pal, good job anyway

[spam1712]

suddenly i have the urge to stick my dick in it

[ydna2]

Interesting, I've never backed a cutter out like that before, did you not have enough clearance for the holder?

[moreebloke]

@ydna2 Can't disengage the leadscrew on that machine when cutting imperial thread. Quite sure it's a chinese made metric machine.

[iiikeman111]

Very impressive. Thanks for posting

[madaboutpix]

wow that is some expensive tooling! Great work love the video!

[simpleinseattle]

Great video. How much did that boring bar weigh? Wow!

[jkamping1]

I would have used a steady myself. U got lucky that it didnt drab or shift while cutting.

[cosast54]

nice work !

[capnjacksparrow1]

difficult in a lathe without a steady, although a few years ago i pulled off a 4 start trapezoidal on a horizontal borer think it was .750 deep and 2.5 inch pitch(for ease of mounting) in cast chromium for the sub sea industry

[dh5830]

You have found that during the casting process the bronze had case hardened. Hence the HSS tool wouldn't cut. Great work by the way!

[jacksonhammy]

fuck oath that would cost a shit tonne

[shadysean1]

never disengage the half nut just keep switching from forward to reverse

[R1K4RD05]

what's the diameter of the hole?

[Mrpsychotehpyro]

Whoah.....this is scary !

My mind produces the vivid images of all the crashes possible...ouch

[nder12345]

where was this filmed

[1braincellleft]

You should have cut a 60 degree angle on the ID before threading, it would have been nicer on the threading bit the first few passes. Just my opinion.

[BigAgitator]

Good luck hiding that in the scrap bucket~

Ie; you better not get crossthreaded on that sucker lmao

[YoungJim409]

Any idea what the part is for?

[mervn1969]

@YoungJim409 , it's a jacking screw nut for lifting train bogeys

[joleenmorganjohn]

Oops, I ment to say (spell) alloy.

[joleenmorganjohn]

Reclocking a thread is a pain. Especialy with an internal thread. Hope you were able to pull a good buck from that job. I never thought HSS would give trouble in bronze. Is it a speical allow?

[mervn1969]

HSS would not even touch it, had to make a solid carbide tool for the job. Material is cast manganese bronze. Thanks for your comments!

[loadervid]

Nice work mervn1969. Sounded pretty sweet too. Looks like bronze, right? I was getting deja vu watching your vid. I used to do some similar looking stuff. Who was the customer, if you're allowed to say?

[mervn1969]

@loadervid Thanks, yep it was cast bronze and tough as nails, I initially tried a tool made from hss but it wouldn't touch it at all. Ended up making a solid carbide tool which did the trick. I have another video of an even bigger thread which will post soon! Sorry, can't divulge customer. Thanks for your comments!

[joleenmorganjohn]

neat job! I would feel safer with a steady rest supporting the end of that peice. Looks like there would be just enough room for one.

[mervn1969]

@joleenmorganjohn Yeah Mate, I ended up running a steady on the end, worst part about the job was having to test the thread and then clock back up again (had to do this about half a dozen times).
