Building the Worden Grinder – the unexpurgated version

[Oompa LumpaParticipant @oompalumpa34302]

I thought perhaps my next comments should be in a new, seperate thread but I will let you guys decide:

Is there any good reason you could not take a variable speed lathe, cut most of the bed off it and use the crosslide, saddle and compound slide to manouvre the position of the cutter – which you could mount in an adjustable toolholder – and mount a grinding wheel to the spindle instead of a chuck?

Would this work as a tool and cutter grinder?

Hi Graham,

Your main problems (aside from and excess of rigidity at the expense of flexibility) could be:

• No facility to tilt the angle of the tool in the vertical plane.
• Some sort of indexed facility to rotate the tool.
• Allowing the part of the tool to be ground to be kept at the right level on the wheel when tilted (tilting raises or lowers the tool tip a surprising amount, probably more than any adjustable tool holder would compensate for).

That said you could address any or all of these with ingenuity.

Thank you for that Neil. I have just recently aquired a small lathe with a badly damaged bed but everything at the head end intact so I am looking to turn it into something useful
