    Sorry but I forgot what a DH is... is that slang for a rotary table?

    I found a set of reverse jaws on Aliexpress for around 25 dollars. The dimensions appear to be consistent.

    How does soft...

    Replacement 3 jaw chuck jaws

    I bought a Vertex 6" Rotary Table that came with a 5" 3 jaw chuck.

    Unfortunately it didn't come with any reverse jaws which is a bummer because I need to grab bigger stuff (for making bolt hole...

    power feed for large mills...

    It seems almost all power feeds on the market is intended for Bridgeport Series 1 machines.

    Do they make power feed for larger machines, like Lagun FTV-4 sized machines or larger?

    I just added...

    Yea, the guy seems not very good at manual machining at all. He doesn't even know how to grind drill bits by hand (I do it for him quite often because he would throw them out once they're dull, or...

    You guys are tough on newcomers for sure... I guess you want to discourage people from wanting to machine for a living.

    On the other hand some of you said don't waste your time grinding HSS flats,...

    It's not that I can't operate a lathe but I guess the guy had to be somewhere and didn't want me taking all day to do it. But the way he's really doing it is pushing the machine, and you have to know...

    I'll be honest with you though, the guy did some stuff on the lathe that makes me scared.

    For example, he would face the cut (before the shaft) by REALLY PRESSING INTO THE WORK with the flat of...

    I guess that explains why nobody sells fly cutters in Taiwan. All cutter stores in Taiwan caters to professionals (they wouldn't be in business otherwise), and almost nobody machines for a hobby in...

    So I borrowed a friend's lathe, because I really don't have one, and I need to make a fly cutter since I can't find one in NT40 (in fact I had no way to buy a fly cutter at all in Taiwan, nobody...

    I just bought a Dahlih manual mill (their website does not list any, these are made in the 80s)

    I'm only asking because my Taiwanese mill does not have a quill power feed and I can't think of any way to add it. However it's not hard to add power feed to the knee but I'm just concerned about the...

    Schaublin mill question

    I was watching the youtube videos from This Old Tony and he mentioned his Schaublin mill has no quill at all, every control is done with the knee and table. So I was wondering, how does one use...

    Most likely, if necessary I may end up resharpening with a diamond wheel on a bench grinder or a dremel diamond wheel.

    It's obviously not the way to go, but this is a used end mill that was bought...

    I don't know who the manufacturer of this end mill is, it has no markings on the end mill itself.

    Truthfully I bought this end mill cheap (sold at 100 dollars per kg) at a used cutter shop. The...
