The metal lathe is the first tool purchased by communal funds at the Artifactory. Members are responsible for providing tooling and safety equipment for use with the lathe, there is currently a small selection of tooling with the lathe including some cemented carbide tools and HSS blanks which were bought with funds leftover from the initial fundraising, if you use these tools please make a contribution to the wear & tear box and if you break them, you bought them.
The lathe is a very dangerous tool and is not to be used until you have had a safety induction and basic training by someone on the lathe trainers list below. As with all of the heavy tools, you should not use the lathe alone or while tired. Long hair must be tied back and no loose clothing should be worn whilst using this machine.
But seriously you need to be trained and know what you are doing to use the lathe is can cause serious injuries.

The lathe takes 12mm tools.
The cemented carbide bits we have are 1/4 inch and seem to be quite variable in their dimensions and tip quality.
Most of these tools are actually 12.5mm to 13.5mm and cannot be used until they are machined down to spec.
Many of the tool tips simply don't cut at all and need some work with a diamond lap.
Some of the tools have now been machined and require shims, these tools are tested ready to go.
There are some advanced tools available for the lathe that are not for general use. If you need to use these tools contact atrophy or Brett Downing. All use of the advanced tooling must be supervised by a trainer.
