How do I mount conical pins? I want to have a couple of defined positions for my top-slide and thought I could use conical pins to do this. I have got the pins and the corresponding reamer. But how exactly do I do this? Do I drill a hole down to the desired depth with a drill of the same diameter as the narrow point of the pin? Do I step drill with some thicker drills afterwards? Second question: I would prefer that the top of my top-slide does not look like Swiss cheese. Is there a way to use the hole in the top part together with several different holes in the bottom part? Thanks Goran Canary Islands |

--- Quote ---Do I step drill with some thicker drills afterwards? --- End quote --- Each taper pin requires a number (two or three usually) of specific size drills at varying depths: see: http://www.icscuttingtools.com/pdfs/tpr-charts.pdf Using one pin and top hole for a number of bottom holes could prove tricky the taper hole depths will have to match very accurately. I wonder if you'd be better of using a parallel pin ? Bill |

Martin Cleeve put a pin in his Myford ML7 top slide etc to do No2 MT tapers whilst GHThomas did another variant- described in ME Workshop Manual. Worth digging out? I tried to put all this on the net- and hit threats of legal action. Ah, well, buy the book. At least , my old friend manage to get that bit done. Norm |

Norm, I am looking through the ME Workshop manual by G.H. Thomas but I have not been able to find the information. Any reference to chapter or page? Is the Cleeve pin documented somewhere? Bill, The reamer I have is specified as 3/16. The pins are 3.70 mm narrow end, 4.7 mm thick end. Depth 22 mm so, if I understand the tables right I should be able to get away with only one drill size. It will be a blind hole as I want to use the lathe side mounted mill for the drilling, to get everything nice and square. Thanks Goran |
