    Scraping? I'd be happy if the guy that made it got around to cutting the bolts a little shorter so I didn't have to use the Vee side of the magbase to clear them

    I did get some Stainless steel bar to make my layflat hose winder pretty. I hope 316 wasn't a mistake.

    Maybe you could buy another mill as a project to cnc, doesn't necessary have to be the same size, as you know with CNC you can just let it take it's time and do it's own thing.

    That's a good idea but honestly don't have the space. I do want to fit in a surface grinder though.

    Default B series Multifix tooling

    Hi Gang,
    I am constantly on the hunt for B series Multifix tooling. Friday I came across a tool post and 4 holders that I secured for $240. Very happy, not original Suisse and not sure of the brand as the identification sticker has gone. Not a big problem as even the clones are rock solid, you couldn't put a dent in one with an Elephant gun.
    So now I have 9 holders, 2 are for boring bars i.e. Have a V in the bottom where the tool goes, 1 large V and 1 small V so all good there. Leaves me with 7 to load with the most used tooling.
    I do need to stop doubling or say x4 on tool posts as I now have 2 original Suisse tool posts and 2 generic. Will have to move some on as I only have 1 lathe.
    Cheers Bruce

    Nooo!

    1. Get another lathe, put it back-to-back with the current one,
    and build a large tool holder hanger/rotisserie between them?

    2. Modify your slide to accept a post for a rear toolholder?

    3. Build a dual-toolholder swing lever, with tools feeding in from opposite sides, for faster roughing or parting off?

    4. Build a new tailstock, with a capstan to rotate between tools?

    I'm sure that warning is entirely justified.

    I have a CNC'd BF20LV running LinuxCNC and I only manufacture one-off components for my home/hobby workshop.
    For one-off's I run most movements by MDI command or for quick/short paths by turning the encoder hand wheel. The real benefit of CNC on a small home mill is the ability to cut holes, mill angles, radius and all sorts of other tasks which require coordinated and precise movement of multiple axis.

    A CNC conversion of a home mill does not turn it into a CNC machining centre, far from it. I'm thinking of my CNC mill as a Semi-Automatic machine which preforms complex parts of my machining tasks automatically but still requires a lot of hands-of tasks to produce a part.

    It is particularly handy for people using programs such Fusion360 which caters well for exporting a CNC program directly from your design to mill a [more or less] complex feature which would otherwise be difficult or impossible to manufacture on a manually controlled mill.

    Default yes, but

    I agree that trying to use a CNC for a strictly one-off job is a debatable proposition, but there are plenty of exceptions.

    On a manual lathe I can machine happily to 0.1 mm, in one direction. The leadscrews and dovetails are a bit limiting. On my CNC, with linear bearings and ball screws, I happily machine to 0.01 mm: 10x the accuracy and resolution. In fact, the resolution on my CNC is 0.8 microns.

    If what I am making is a complex part needing high precision and of real value, then using the CNC may well be justified (see above). Sure, I might run off a plastic prototype or two (or 3), but if the job has high value, so be it. And of course, if something goes wrong with the part later on, I have the means now of replacing it exactly.

    Yes, I could use the MDI screen, but the potential for typos that way is ... high. A written program can be reviewed and cycles of air-cutting can be checked.

    Cheers
    Roger

    Thanks for the replies.
    Yeah I'd like it rather than getting out a rotary table or using the DRO functions etc,
    One day I'll get around to it, then I'll either be why didn't I do this sooner, or jobs will be a pain, lol
    The screws and double n are well kept wrapped in plastic, well oiled and in a sealed pvc tube with end caps.

    I understand it can still be used manually, but still like winding handles for a quick job

    Default Surface grinder

    From my factory neighbour's yard, an old thing that used to make things flat:

    IMG_1275.jpg IMG_1276.jpg IMG_1277.jpg IMG_1278.jpg



    Sadly, the middle of the long travel is worn/inaccurate, and I don't have the appetite for regrinding the table underside of a surface grinder, so off the scrap it went.



    ...

    but I did keep the motor. Nice compact 3Ø, 2.2HP from a quality Italian manufacturer?

    What a pity. It’s a tool and cutter grinder - for most jobs a bit of wear in the middle wouldn’t have been an issue.

    Aah. I thought it was a surface grinder.

    Sadly, don't have space for it, and it has sat outside for 2.5 years, and the owner had to move it in a hurry

    Yesterday I got four Sutton Thread Repair Kits in M6, M8, M12, and MF14 for a grand total of $60. Also got a Impact Driver Set, a Smart Bit for drilling and countersinking and a P & N 5/32 - 1" Step Drill. Total for everything was $140. All brand new.
