this was in the States, out in the Country. We had a '63 Ford Galaxie, color Light Blue, which developed a strange Problem in 1968. Sometimes, not always, it would burn "Oil" and leave a blue Cloud behind it like a war-time Smoke Bomb. Us Kids thought it was fantastic - naturally we named it the "Blue Streak". It was odd that it was an intermittent Phenomena. Even more odd, there was no detectible loss of Engine Oil Level. It dawned on me one Day to check the Automatic Transmission Fluid. It was quite low, so it went to the Ford Shop. I remember the Repair Cost was surprisingly low. They had replaced something the Guy called a "Vacuum Diaphragm" which he said was in the Vacuum Line between the Carburetor and the Automatic Transmission. Today I doubt it was a true Diaphragm but rather some sort of Oil Limiting/Collecting Surface. Bruce, Oh yes it was Oddly the Ford cruise-o-matic box normally only used 2nd and top, 1st was only engaged when you flood the loud pedal. |

Vacuum capsules, put your foot down hard, the inlet vacuum drops so the box drops a gear |

You can of course use an old carbon arc torch with SIFbronze if like me you still have one from the 70's. |

Dry firebox is not new. Bullied Leader for one. It wasn't a great success to put it mildly, but the die hard steam enthusiasts won't accept that as a reason not claim that with a little more effort they can save the world. Perhaps it's new because it's half dry and half wet firebox if the side stays are anything to go by. And why is releasing 20 years of locked up carbon a green idea Edited By Dave Halford on 26/05/2023 17:39:49 |

Is the Clarke CMD300 more equivalent to Sieg SXP1 or SXP2? Wayne, The answer lies in the specs tab for each machine. It is more SXP2 table wise. The Clarke is more expensive (you still need all the bits Arc bundle in) and I don't think the Clarke is a Seig and when Clarke cease to sell that model spares become unavailable. You need to be very careful when comparing the power in Watts. Some UK suppliers will list the output watts which is a mechanical figure, others will quote the input electrical power which will be a larger figure. |

Wayne, If you have a grand spare the Arc Seig mill bundle will start you off. Anything cheaper is a toy and will disappoint. Less spendy are the secondhand belt drive round column type mentioned by Clive that look similar to the current Warco Major WM50. They were made in 3 sizes back in the day when Warco sold all three, they called them Economy (1/2hp), Minor (1hp) and Major (2hp). The Major was and still is enormous for a bench mill needing 1sqM of space and has been sold under various names. This is an Axminster version The Minor is probably the best size, your problem will be fetching it yourself and making sure it has all the handwheels intact. |

Why is it that when one buys a power tool that comes with a new box that you cannot get the cable back in the box when you put it away?

How did all the riders of Japanese bikes and the British bikes just before discs came out cope with twin leading shoe brakes on hill stops? Edited By old mart on 13/05/2023 19:53:59 My 1974 CB175 twin leading front was much better the discs of the day and worked fine on steep hills. Caravan brakes don't work backwards these days and you no longer have to lock the brake actuator manually to reverse it. |

13/05/2023 16:21:32 |
Something with a bit of 'give' underfoot is much easier on the feet and legs. Thats one of the reasons old machine shops had duck boards to stand on at each machine. Why not lift the walking floor level to match the garage, but leave the machines on the concrete. |

From my armchair and Lathes.co. ML7: Speed Range: Has anyone killed an ML7 by over revving? Possibly, but then no one would admit to abuse. Myford would not have put together a kit to upgrade the bearings if there hadn't been a demand. Even the slow speed overheat issue depends largely on the motor insulation type and wether it's rated for intermittent or continous use. The former may suffer from low speeds. Most VFD's are designed to be controlled via a pendant, which is why some VFD have exposed live terminating screws similar to chocolate blocks .
