 As well as several locomotive builds and redesigns so I can go and build them. I am refurbishing a MK 1 Super 7. The photo shows parts resting on our existing lathe. Poor thing sat in a leaking workshop for about 30 years until August where I loaded it into the car past a waiting skip. The Griptrue chuck came with the MK 1 as well which thankfully saved the spindle thread but the chuck was solid in rust. The only way was to dismantle after a month of soaking and hammer the jaws out. The other set of jaws are missing but I do have other chucks. There are myths, legends and story's of machines got for free... Yes this happened and reflected in its condition before many hours of getting a superb finish. Cellulose sprayed on a hot afternoon on top of a pile of concrete blocks sat on polythene. David and Lily. |

 This is what we started with straight back from the Leaking workshop. A nightly spray with various penetrating oils and eventually things began coming off. The dial on the feed-screw for the cross-slide had to be turned off. I dreamed of someone spraying it with used engine oil from one of the abandoned first and second and third cars left within the 6 acres of mostly woodland. The 2 Brothers moved in 70 years ago. Dad built the wooden house and Workshop and kept adding sheds and sheds and never threw anything away. His favorite car still waiting 30 years later in the Garage. He was deeply involved in The Reading track 50 years ago. The property is now for sale. Hence the bunging out of machinery. David and Lily. |

Wow! I wouldn't have believed it was the same machine! And done so quickly too!

I genuinely would have thought that far too gone. I love salvaging equipment. There is a common hobby of people taking nice old equipment and adding a filament bulb sticking out at an odd angle and calling it a lamp. I recently saw many hundreds of pounds worth of dallmeyer lens scrapped because it looked like it would make a nice lamp... the person salvaging it had no idea of its value. This is to me the opposite, taking something that looks only fit for the scrap heap and giving it life again. Perfect.

The chuck surprised me as this cleaned up very nicely. In fact having put it on my other Super 7 to take the photo, have been using it to clean up and blend in turning marks on a new set of buffers. New to me he adds!
As for the bed... I expected the worst but this is amazingly good. There is one place where it got nibbled by water building up against the rear of the saddle. Judging by the drive belt not used much. Plus the MK 1 Clutch needs dismantling to change belts.
I of course have one problem with the new finish that if you look at the Super 7 it is on, the BRUSH Painted sticks out somewhat.
All painting on the Forum has of course a new Bench Mark of 1501.
David and Lily.

 Yes the bed surprised me as well. Just the minimum amount of work applied. All the work was getting grub screws free and the gib strips off. Every part cared for lovingly after a quick add up of the prices new. The saddle could have gone 2 ways. Lack of oil under and it is rust welded to the bed. Yes the garage now resembles a second hand Lathe sales area. Bits of Raglans sneaking into the picture. Now I have Tamed the Picture site. Honestly the first Photo took hours as they do not seem to have a step by step guide. It was trial and (THAT'S TOO SMALL) and re edit error. Then you discover Drag and Crop!! He jokes. I have about 4, Four jaw by 6 inch chucks for Myfords and one came with this lathe sat under the cross slide in the photo. Very ceased and I can't take the back off to bang out the jaws like I did on the other one. Solid with rust it has been abandoned twice. It is a Burnerd. David and Lily. |

Hi David.
That's a great job you are doing!! To free up the 4-jaw rust, if you can soak it in WD-40 for about a couple of weeks, normally that would ease it enough to dismantle. I would suggest wrapping Duck tape around the body to seal the adjusting screws and make a trough to hold the WD-40.

 Lucky as the back came off and I could gently bang the jaws out. No such luck with the 4 jaw. I have one twisting and a gentle bang and back to soaking. A Raglan Tailstock is still stuck from late January. More heat needed and a space for the Heavy mob!!! David and Lily. In early due to the clocks. |

Hi David, you must love restoring old machinery, it looks like most of it will be successful. What is the part of the 4 jaw chuck called as I need new ones for mine. Brian.  4 jaw chuck by Brian Leach, on Flickr |

Hi David, you must love restoring old machinery, it looks like most of it will be successful. What is the part of the 4 jaw chuck called as I need new ones for mine. Brian. I had an old, smaller, 4-jaw chuck and found that the adjuster screws could be made from large allen head grub screws, and just needed a groove turned in them where the jaw engages. Whether or not you can find suitable threaded grub screws these days is more problematic! |

No, all the ones I have come across are right hand thread, all you need to do is find out what the thread is!

Being in steel it may be possible to do a weld up!!
I may post up a 4 jaw progress.
One jaw moved out 1/4" over the last 2 days.
Back to soaking in stuff!
David and Lily.

Brian I don't know what make and size your chuck is, but for whet its worth my 4" Burnerd chuck uses 1/2" x 12 TPI BSW thread form for the jaw screws. |
