Hi Guys, I posted this as part of another thread but since I seem to be making fly cutters lately I thought I'd post it/them here. The first one is a simple 1/2" inch thick disc, in this instance stainless steel, with a 2.5" inch length of 16mm silver steel rod for a shaft, turned down on one end to be a press fit into a 1/2" inch hole drilled in the centre and an 8mm hole drilled near the edge to hold a 6mm square toolbit secured with a 2Ba grub screw. There are a couple of pictures of the toolbit cutting edge. |

Hi Guys, This is the second fly cutter. Similar to the first one but intended for a different job. Here I used a cast iron disc 3" inches in diameter with a milled a slot to hold a 6mm toolbit horizontally the tool bit is held in place by two M4 grub screws. Also I used a M10 threaded spindle cut from a short length of 1/2" silver steel rod so that I could use the spindle for another job. I think that I cut the threaded part a bit small since the threads have a flat top on them. |

Still need to make one of these. Mine does not perform as well as it could. |

Hi Rick, They are pretty easy to make. Both these were made with scrap bits culled from various places. The second one using a cast iron disc is more complex but still not difficult. As you can see from the pictures I made a small error in the diameter when turning down for the M10 thread but it fastens securely and buts up to the flange dead square. I'll take some more photos of the second one showing the toolbit and fastening screws. |

I was thinking of making a head I can attach to my Taig slitting arbor. Then I just have to make the disc. I should start a list of what to make, so I quit forgetting what I need when I get in the shop. |
