If you have a mill & boring head you could use the method I used, since I didn't have large enough material for buttons. http://bbs.homeshopmachinist.net/showthread.php?t=45649 |

Hi Peter, excellent work on cutting the gear. I`ve used a single point cutter in the past on a clock wheel and I didn`t find it great. You have obviously done a good job but I like the idea of profiling the cutter in one shot, using this tool John describes. I fancy giving it a go but clearly single point cutters can be used with success. I`m just making a little boring bar setting device at present, then I`m going to jump to gear cutting. I`ll let you know how it goes. |

Chris, I just finished cutting two bevel gears to repair a friend's radial arm saw. Pictures of the tools and gear attached. Cheers, Adrian |

Fantastic !!! :mmr: :mmr: That is mighty helpful! I`ll hopefully make it in the next couple of weeks. I have done on the calculations based on John Stevensons tables and the only thing that confuses me is the infeed. I know in Ivan`s Workshop Practice series gear cutting book, his numbers are different but my understanding is that Ivan touches the centre of the front leading edge of the profiling tool on the front edge of the cutter blank, moves to the side and then infeeds. So a lot of the start of the feed is a blank cut in air. Am I correct that when using the this method. The centre of the profiling tool is centered with the middle of the cutter blank, moved in until either edge of the buttons are just touching both sides of the cutter blank and the "feed" is measured from that position? Once again, thanks for the pictures. Very much appreciated. Chris |

Chris, Your description of the operation is correct. The in-feed tables in Ivan's book assume that the feed is measured from the most forward edge of the cutting buttons. As you described, I touch the leading edge of one of the buttons to the end of the tool blank, reposition the tool blank between the buttons and proceed with the cut. Drawings of the 16DP #6 cutter used to cut the bevel gear attached. Cheers, Adrian |
