Roberts Patent Posthole Lifter.


An essential tool for the safe lifting of an old posthole so it may be recycled for further use.

Roberts Patent Vacuum Posthole Resizer.


An essential device for any posthole mining operation. Postholes in their raw and unrefined state must be precisely sized and cleaned before they are of any use to the prospective customer. Unlike earlier devices the Roberts Patent Resizer is able to recondition used postholes to precise Board of Trade specifications so that it is impossible to tell them apart from newly refined and unused postholes.
It is this improvement in design that has earned the Roberts Patent Resizer the Society of Aetheric Research's gold medal for the innovative and sustainable reuse of a finite resource.

On closer examination of the Stackton Tressel Light Railway we have discovered a series of holes by the old loop line. Is there any way of identifying where these holes my have been mined or their age?

The company clerk is currently searching the railways records to establish where these hole may have been mined & purchased.

If it turns out that the holes are unique, then the company may apply for heritage status on the holes and explore the possibilities of moving them to the local museum at Stackton.
