Repton RT1 Radius Turning Tool

Repton's RT1 revolutionises the process for turning concave or convex radii for the manual lathe market.

The RT1 is unique in the way that it is mounted to the tool holder of the lathe and unlike most ball turners does not need the removal of the tool holder to mount.

It is possible to swap in between the RT1 and other turning tools in seconds.

Not only does the RT1 allow you to create balls unto 60mm in diameter but it will also turn concave radii unto 60mm.

The applications for concave turnings are almost endless from pulleys to dies it will save you much time and expense.

Repton RT1 Videos - Seeing is believing!

Easy Tool Alignment

The Repton RT1 has been designed to make the difficult task of creating radii as easy as possible.

This can be seen in how easy it is to locate the tool on the workpiece, where other radius turners need precise measurements to accurately locate the tools the RT1 just needs one minute of simple steps.

The cutting tool is securely held in place by four mounting bolts.

The mount has been designed to ensure that the cutting tool can not move as movement is one of the main reasons for tool chatter.

Turning a 60mm Diameter Ball

In this video we turn a 60mm ball from a piece of scrap aluminium.

The aluminium billet has been drilled and tapped to mount on to a threaded shaft that is gripped in the chuck.

The ball is then polished to a mirror finish and then removed from the shaft.

The Repton RT1 eliminates the need for CNC machinery to create an accurate radius. The small workshop machinist has never had such a cost effective way of creating repeatable internal or external radii.

Turning a 60mm Concave

This video demonstrates the RT1's ability to easily turn accurate concave forms.

We have used the RT1 to create replacement pulleys and dies for tube bending equipment.

The Repton RT1 can be used on a huge variety of materials.

The included carbide bit can be used with most ferrous and non ferrous metals and various plastics too!

Turning a Radius on a Bar End

Demonstrating the RT1's ability to achieve great results on substandard materials.

This bar was from the scrap bin but had previously proven to be not very machinable as you can see there are no tendencies for the tool to chatter.

This is because of the unique double bearing construction that has been designed to reduce both axial and radial play.

Will The Tool Fit my Lathe?

With lathes there are very few standards, tool fitment can vary depending on modifications such as the cross slide, or tool post.

The Repton RT1 needs certain clearances to work properly.

The important clearances that you will need in order for the tool to work with your lathe are as follows;

From the bottom face in the tool mount, the face that the tool sits on, you need 68mm of clearance above the ways.

The second important clearance you need is the tool tip sits 10mm higher than the previously mentioned face.

Providing you have these clearances then the tool will work perfectly!

We have used the tool on mini lathes such as the Clarke CL300M up to a Colchester Triumph VS 2500!
