Re: 1/2 hex shaft coupling
I would recommend investing in a hex broach in both 3/8 and 1/2 inch sizes. You will not believe how much they will get used. We needed similar couplings last year and could not find any so we made them by broaching 1/2 inch round shaft couplings

Re: 1/2 hex shaft coupling
We are using these this year, from Team 221 systems. They seem to be working out alright.
http://www.team221.com/viewproduct.php?id=137 The problem with buying a hex broach is you have to buy an arbor press big enough to use it. I know we don't have the space for that until next year when we get our new shop. |

Re: 1/2 hex shaft coupling
I prefer not to use set screws, generally. The only ones I've had decent luck with are the ones with knurled points to help prevent backing out.
If I were connecting two shafts together I would use a few spring pins, dowel pins, or cotter pins. Also consider axial shaft retainers. A little fancier, but they can work quite well. |

Re: 1/2 hex shaft coupling
Buy a 1/2 inch deep well socket and cut the square end off.
Easy and cheap. |

Re: 1/2 hex shaft coupling
Well why didn't I think of that last year. Good suggestion.

Re: 1/2 hex shaft coupling
Thanks but I think BJT actually beat me to it.
