    Re: Thread cutting in chinese ballscrew

    So if you are following the usual dimensions you will find the a M10x1.5 does not pass over the 8mm section. We typically use M10x1.0 as it also allows you to get a finer adjustment on the locking...

    Machining the castings is somewhat irreversible since the parts are hand finished to fit. You can just buy a saddle but you will need to get it reground and fitted which, unless you have all the...

    Re: double sided fsw and isf

    NEW MEMBER: Re: New member, Lagun Mill

    Tripping an RCD means you have leakage current to ground. This could potentially be fatal so disconnect the machine and test which of the power or signal wires are shorting to the chassis. On my KRV...

  14. Re: Bridgeport rebuild, Turcite or Marlon anti friction material

    The latter. Brian is a very helpful guy and can get you machine in tip top shape for a very very good price.

    Distilled water is deionised water using heat. Normal deinoised water for batteries and such is virtually the same thing but made using reverse osmosis and thus cheaper.
