| The Sequel - Oh Blimey I bought a CNC Lathe (Beaver TC 20) |

I'm beginning to see why every good home should have a cnc plasma cutter. :clap: |

Oh yes, those upper pivots would be a right pain to do by hand, whereas they took about 45 minutes including drawing up in Autocad and steaming up the machine. (cutting time maybe 2 minutes !) |

An old friend, now deceased, bought me some labels for my machines, with EGHSO engraved thereon. "So what's Eggerso?", I asked. "Every Good Home Should Have One", he replied. :D |

I was wrong - that weight is only 20 kg not 56 lbs - but close! I added a second, and although the winch has no problem lifting the 40 kg (which is close enough to the 47 kg of the chuck for test purpose) it is of course still chewing it's gears. The worm is a two start one, and at 6 o'clock and 12 o'clock on the handle you can feel the starts of the worm hobbing the gear to shape :bugeye: I cut a pair of angle fillets for the main mast fore and aft (Z axis) reinforcement but there's not much room to add anything more to the abeam (X axis) direction. I think I'll weld together what I have and see how much flexing that I get, as I'm concerned that the whole thing is getting pretty heavy. Make it too heavy and it defeats the object of having it ! To stop the base twisting I have both 3" and 4" box profile that I could weld on underneath, but it's the weight issue. If the twisting is too great I 'could' add a detachable outrigger resting on the floor :med: No welding today - I have a fencer working and it's amazing how often he needs words. I've already straightened his Eastwing hammer on the 60 ton press :clap: ) |

Andrew, How smooth is the worm? That's what's going to determine how long it lasts! Cheers, Matthew |
