    That was probably a B&S 558 cylinder square. Not made anymore but very handy if you can find one in decent shape on Ebay etc. It took me over a year to find one in the condition and price I was...

    I looked for a thread with a South Bend head Marty, did you mean the one with the Criterion head? I suppose there could be other causes, maybe poor storage or trying to remove the shank from the head...

    With what I have tied up in machines and tooling over the last 40 plus years that are hardly ever used for actual gunsmithing and never on any gun I don't already own. You'd have to have a hell of a...

    Very cool engine and I'd agree with most here. Not a scale model of any particular engine, those out of scale bolts indicate it was built to do fairly hard work and stay together while doing so. Just...

    You don't necessarily need an actual cross and/or top slide for taper cuts, but it depends of course on what your attempting to do and the accuracy required. It's not uncommon to use what are known...

    Newtons third law, "For every action there's an equal and opposite reaction". For machine tools you'd subtract that reaction from the machines own mass, rigidity and resistance to those forces. Once...

    No those small horizontal / vertical Hardinge mills weren't gear heads, Emco made a 6 spd gear head round column to name just one. But again $600-$700 isn't going to touch one of those unless it's...
