    does that mill come with an assortment of collet's. and what is the taper. M8 is probably the most common for small mills. ez to find used stuff for the M8. like was said already it's the accessaries to make it do what you want that rack up the dough.

    It's a slippery slope you've embarked on. First it's a mill/lathe then the accessories then you start looking at a used Bridgeport and a WWll era lathe with ALL the attachments.
    Then you catch yourself watching youtube videos of peoples one-car space machine shops.

    Yeah, if he had a mill his bike probably would have gone 400 mph.

    I've been a home machinist as a hobby for quite a while. A couple of other tools to keep close by is a digital caliper and a bench grinder and of course a PC with an internet connection to search for help when questions arise. That last one really helped me when learning how to properly cut threads and make/sharpen custom cutters like internal thread cutters.

    1st thing I do with every new machine is completely disassemble it and clean off all the packing grease and oil the parts and apply good lithium grease where needed. Not only does that help get you very familiar with the machine's design and how it operates it allows you to ensure that all parts are properly tightened and aligned and working properly.

    After that get scrap stock material and practice. Best way to learn how to use this machine after you read up on some techniques is to just get your hands on it.

    ***** I CANNOT STRESS THIS ENOUGH!!! ALWAYS! ALWAYS!!! ALWAYS!!!!!!!!! WEAR SAFETY GLASSES WITH THIS MACHINE AND BENCH GRINDERS!!! ******

    The cuttings that fly out are hot. Also be advised that some cuttings come off in long strips and are as sharp as razor wire. I've made so much 'razor wire' like steel wool it's not funny.

    For your own safety and to protect your valuables always remove rings, necklaces, tie back long hair and stuff down the back of your shirt, wear safety glasses, use a fan to blow smoke from cutting oil away. Rings can also cause damage to what you're working on in the lathe.

    As others mentioned use proper cutting speeds for the material you are working with. and make practice parts with cheaper material if working with expensive material. I worked with stainless steel which is expensive yet regular steel is cheap. I like to make my mistakes on the cheap stuff and adjust my techniques before I make the real thing.

    Once you get the hang of using your lathe and mill to make your own parts and tools (yes you can even make your own taps and dies with drill rods and save a ton of money) you'll be in 7th heaven and the envy of your neighbors too.

    My shop is, well was Carol's garage. Don't think a car has seen the inside of it for a year. Started out with "But I ride that bike every day and it needs to be in there" then a small work bench. Then a larger work bench, now 3 walls, a welding table engines, bikes and tools.

    Man I love MBs. Always some thing to learn, do or try.

    Ergh! Just typed a wall of text and as soon as I hit enter, got bumped off line.

    Nope, it was there, lol

    Does not come with any other tools that I know of.

    Dan Greg here, I have used both a lathe and milling machine for over 30 years at work. You will be able to make what ever you can dream up! don't forget as was posted earlier glasses and ear plugs are a must. I wish I had worn the ear plugs more.

    Was getting a physical to ship out on a tanker. (New job) Nurse who was putting me in this box told me that the old guys all did better then us young guys. (was a very long time ago) I asked why? Some of the guys were WW2 vets who sailed very large ships with very large guns who were being shot up with very large shells.

    With out looking up, she said "you guys play your music to loud" Cracked me up at the time but am noticing it now.

    First (prolly dumb) question. I want to make a part that enlarges the predators drive shaft Dia. 5/8 to 3/4. Also lengthen it by drilling out a 3/4 round stock with a 5/8 bit then milling a slit in for the keys. One on the drive shaft and one for the keyway on the sleeve/part.

    How do I go about drilling it out? In researching this tool, turns out (big time bummer), it cant do threads? I thought I could add a chuck to drive a shaft in to drill it out. (Told ya might be a dumb question) Or am I resigned to using the drill and try and center it?

    Dan the slide device with the center punch comes out on most and a chuck goes in, can't tell if this machine has that feature.
    Went back and looked again, looks like the anvil has a mic. on it so if the center pin comes out you can drill the shaft.

    To drill it out, I would use drill bit in a chuck mounted on the tailstock, with the shaft in a 4 jaw chuck, dialed in for greatest accuracy. 3 jaw will do but will prolly be a few thousands off center.

    When you spin the shaft against a stationary drill, the drill automaticly follows dead center.

    I would drill it undersize and use a boring tool sneak up on the desired diameter.

    I would make a sleeve that is a slip fit, then cut a slot for a key, and use a wide keystock to traverse all the keyways.

    You could prolly make one from bushing stock tubing, from Aircraft Spruce.

    I also think that I have seen such bushings for sale somewhere, like Graingers or McMasters

    Kool and thanks again. Always a way.
    Kinda panicking. Lots of money, dang thing is 2ce as big as I thought and was worried it would not do the one thing I bought it for. Just buyer's remorse I guess.

    Really am grateful for you guys, thanks !!!
