    Took the words right out of my "hind sight". The other poster did not invent the slander no, but it serves no purpose to propagate it here.

    Of course it was about Islam, which has nothing to do with this thread. I'm not going to explain how racism works, look it up if you must, but it extends to cultures, ethnicities etc. Islam, being a...

    What an uplifting thread, filled with colourful anecdotes and humane responses to an original post that is completely relatable.

    Did you leave a turning tool a touch far out of the tool block and have it bugger up the rear way when you called T5 or some such event? Why the tirade against turrets? Has no one else thought of...

    Awesome idea. Gravity would allow for the entire mass of the bar to be accelerated by 9.8m/s^2 and then impulsed back to 0 when it hit something rigid. You don't need a hard stop if you simply...

    I'd do as thermite suggests and skip the mill altogether. It doesn't make a whole lot of economical sense to use a mill for this job.

    Your holes are about 3" apart, so just hand crank it if you...

    Run a poll if you want numbers, but I vote to ban grizzly and jet entirely. There needs to be a line drawn in the sand; if I want to peruse HSM I will (or the SB forum...)

    The King mills are exactly the same as any other generic import bridgeport, which makes them not great but decent. I've used both a generic King import and an actual bridgeport in the same shop, and...
