Clock wheel cutter

Looks like your cutter is blunt or you've got the wrong cutting angles, you should use a high speed, the type of material will definatly make a diference, but a darn good try I've learnt something watching.

The teeth looked pushed out rather than cut?

I know you wanted to make the cutting tool, but it might be a good idea to buy one to start with.
Would eliminate one possible problem and allow you to master the actual setup and process.

OK - I totally agree, the teeth gaps look pushed out rather than cut out. I think I`ve made a huge error as I aligned the cutter and wheel on the x-axis and then fed the wheel straight into the cutter on the Y-axis. Consequently, is this not simply pusing out the groove rather than using the cutting angle and cutting it out or have I done it right? I appreciate the tool may not be to correct size for module .8 cutter but in terms of the cutting angles and rake, the tool looks fine and is sharp. Have I been cutting with it incorrectly? In my mind, thinking about it now, I`ve been "hitting" into the face of the brass with the face of the cutter rather than using the cuting edges, no?
