Before I left home for work, I did tighten it up and the misalignment is apparent. I'll just declare it good for the time being to carry on with the project. May make the replace part(s) if there is a need to. Regards, Wong |

This session stopped prematurely when I cut my right thumb while tapping the arbor. Blood was dripping on the floor and table when I rushed to wash the wound under running water. The pain was terrible when in contact with water. Thank God it was just a cut. Though a little deeper than what I normally get, it was nothing serious. My wife, of course, nagged a little while putting on the plaster for me. The blood started dripping off my thumb when the latex glove was removed. Back to the making of the 1/2 centre. The 60-degree point was completed this session, after struggling to make the arbor. While parting off the workpiece, the HSS parting blade snapped. It was cutting after a while and snapped when I tried pushing it further. Another view. Swapping in the Proxxon part off tool. It completed the job without much trouble. After facing the end flat, I centre drill and drill about 12mm deep for the 5/16 BSF. Tapping the hole to hold the 1/2 centre. This was when I cut myself. Notice how close the tool was to the tapping handle? My hand slipped and my thumb went on to the cutting edge of the tool. There was still wobble when I mounted the 1/2 centre to the arbor. I pushed on this time, facing and turning it. The 60-degree point was completed. Notice that the centre is now tightly screwed onto the arbor as if they're one piece of steel. After running a smooth file on the face and sanding it down with fine grit sandpaper. I fastened it down to the mill vise to prepare to drill the tommy screw hole. I stopped work at this point as the wound has started bleeding again. I will try to complete this part of the work tomorrow morning before church. Will also attempt to harden it by using my little Proxxon Micro Torch and quenching it in water. |

Wong, Nicely shown and posted, looks good, nicely made. :thumbup: :clap: Sorry about your cut thumb, - try to make sure all the sharp bits are out of harms way. That goes for the dead centre in the tailstock as well because that can also cut you. Don't forget you don't always have to part things off, it is quite acceptable to use a hacksaw and face it on the lathe afterwards. :thumbup: It is really coming along very well :bow: :beer: DaveH |

Hi Norman, A little flesh, blood, and sting indeed. Not the part on pride as I've yet to reach that stage. The proper tools you spoke about are the tailstock tape & die holder? I plan to make them. When I was using the tailstock, I always find the top slide in the way. Do you normally remove your tool post when using the tailstock for, say, drilling or tapping? Also, I saw some YouTube videos showing tapping in the lathe under power. Is it advisable? Anything to look out for if it is. Thanks. Regards, Wong |

Dave, Thank you. 3 more parts left to make; 2 adjustment screws (I'm thinking of just buying them than to make them) and the 2MT arbor. Regards, Wong |
