Rear Tool Post

• The ability of the rear toolpost to better support a parting tool to resist deflection whilst cutting, and hence reduce the incidence of the dreaded ‘dig in’, is well known. It is able to do this partly because the top-slide is not used (removing one de-stabilising slideway from the equation), and partly because the tool is cutting on the reverse side where the forces tend to ‘lift’ the cross-slide.

• The effect of the latter is to push the surfaces of the slides into closer contact with each other. Both of these components exist when cutting tools other than a parting tool is being used (an exception being a boring tool set to cut on the near-side of the work).

• The advantage of the system is that all the attachments are rapidly interchangeable, and once set correctly centre height is automatically maintained. Of course I also use standard 4-tool turrets on the top-slide for other work.

• The rear toolpost is a common addition to the amateur’s lathe, yet probably the advantages it offers in terms of stability and cutting tool stiffness are not fully utilised.

• This is a standard pattern base unit, to a design adapted from an illustration in the book ‘The Amateur’s Workshop’ by Ian Bradley. Many other designs have been described in Model Engineer over the years but all serve a similar function.

• It is fabricated from standard mild steel sections and fixed to the boring table by two bolts placed immediately below the cutting tool. The action of tightening the clamping handle locks the attachment to the body using a long T-bolt which passes through the centre of the base column, and is thus also locked to the boring table.

  PRODUCT DESCRIPTION:
