    For aluminium, try metholated spirits (or rubbing alcohol, as we call it where I live) as a cutting fluid. It prevents edge build-up, evaporates quickly, and leaves no waxy residue like WD40. I've never used kerosene, but it does make sense that it would work. From using it for other things, though, I'd think it would leave some sort of residue. But if it slows or prevents rust, so much the better. I enjoy your channel, by the way. Thank you for sharing.

    • @ballbous
      @ballbous ปีที่แล้ว

      Methylated spirits are usually denatured ethanol, whereas rubbing alcohol is usually just isopropyl alcohol(potentially scented in some places). Will work just the same, Methylated spirits typically smell horrible in places where they're consumed as alcohol.

    I don't know if you watch Rustinox, but he recently turned me on to glue bottles? I had not heard of them. It's an oil can with a brush built in to the end. When you squeeze the trigger, oil does not shoot out. Instead it flows right onto the bristles. Very clean setup, one-handed oiling.

    Have you considered using an old poison spray pack to put coolant on the part. Just need to be able to pump it up between jobs and you should be able to get a fine mist right where you need it. I personally have not tried this yet but I have been thinking it is a cheap way to use minimal coolant without resorting to compressor and commercial kits.

      I doubt it. Transparent ABS (Strickly speaking MABS) is something of a specialized material and fairly expensive. Judging by what the plastic was salvaged from I'd say its more likely to be polycarbonate or polystyrene. I've been in the plastic industry for 32 years the last 15 or so as a process engineer. Transparent ABS is something that just doesn't come up hardly ever from a production and design standpoint. At least in the portion of the industry I work in.

      With the fixed speed motor I have and the belt pulleys, I can't drop the rpm low enough to cut threads under power.

The sherline I have has a pretty similar method to this.

    now that you have both, which one would you buy first: lathe or mill ?
    I will be mostly drilling the 23 mm hole in the rectangular aluminium block, and a few smaller holes in the corners, which I can handle with my drill press. but that large 23 mm hole is a tough one to make in batches, and I don;t feel safe doing it on the drill press either. I clamped it as hard as you can imagine, and the drill press is still vibrating like mad, and the table is bending slightly downwards from the force, and that also makes the hole slightly out of perfectly parallel to the block's walls.
    unfortunately I can't afford 2 machines, and I need to wait maybe a year to buy another machine.
    your advice would be greatly appreciated
