Radius Maker For the Lathe
I show you how easy it is to make a Radius Maker by your own.
When you understand the drawing here below, you can make it.
Oke , it’s not a beauty but it works very well.
So, let’s start.
Place a square piece of material in a 4 chuck.
Drill a hole in the middle.And make it, in my case, 20 mm.
and make a chamber for a ball-bearing
Make a flat cylinder. The cam in the middle is for the ball-bearing. The thickness of the edge is the same thickness of what left on the plate.
Place the cylinder in the 3 chuck of a milling machine.
Make a slot in it.
place it in a bench-clamp and make sure that the slot is horizontal. Make with a flat cutter 3 holes in it. After this, drill 3 M8 screw holes till the slot.
Drills a hole for a long bolt. Do it not at the same side as the 3 holes.
Make a L shape of steel with the thickness of the slot in the cylinder.
Put all 3 parts together and place it on the lathe and mark the height of the L-shape.
Make with a milling machine the height .
drill 2 holes for the cutter.
Place the L-shape in a clamp and rotate the clamp for 30 degrees
make a rhomb shape.
clamp the pieces together with a countersink bolt.
Now you are ready to use
