Line Boring FAQs

Yes. The rig is fully mobile and self-contained. We set up in your workshop, your yard, or out in the field, anywhere in Victoria and beyond.

Can you remove a seized or stuck pin?
Yes. We extract seized pins and bearings with hydraulic and thermal methods, and oxygen lance pins that will not press out, without damaging the parent bore.
Are you really available 24/7?
