Description

Thread milling with the HOPE easy threading jig.

Thread milling on your lathe has never been easier than with this tool. The cutter goes into the spindle and your workpiece including the chuck is placed in the jig. By turning the spindle of the attachment, your workpiece slowly rotates along the cutter and a thread is milled. As standard this attachment is available for tool rest holders (banjo) with a 1 inch and 30 mm mounting. If you have a different shaft thickness on your tool rest, let me know.

About the thread attachment

You put together the Simon Hope screw thread jig yourself. You have to choose from a number of things;

Thread. what is the thread of the four-jaw you are using? you can choose in the drop down menu from M33 x 3.5 mm and 1 inch x 8 TPI.
Tool rest. What is the thickness of the chisel rest mount? you can choose 1 inch (25.4 mm) or 30 mm in the drop-down menu.
Pitch. What is the thread you want to mill? You can choose 3.5 mm, 16 tpi or 10 tpi in the drop-down menu. (You only choose the pitch, after all you determine the diameter yourself. So you can make M33 x 3.5 but also M41.5 x 3.5)

Easy

This attachment is called the Easy-set threading jig. That is because adjusting the attachment is very easy to set up. Adjust the attachment exactly parallel to the bed ways, so that the cutter in the spindle of your lathe exactly touches the wall of your workpiece. You mill the depth of the thread in a number of passes. And adjust the depth of the cutter in steps with the step wheel.

Video

Of course I can explain it completely, but a video is always easier. Simon explains it himself in the video below.
