This is going to be interesting. There was an article in 'Model Engineer' No 4432 15th June 2012 that told the story of using an EDM machine to cut a cylinder block for a 4"scale traction engine model. |

Hi Andrew I thought that it was kind of quiet on your corner of the island lately. I guess that is because you were working behind closed doors bringing yet another machine back to life. You will have a good following on this I am sure. :D :D Cheers :beer: Don |

I gather from your description that this machine operates with the wire through the workpiece cutting a bit like a bandsaw?

So where to start :scratch: Realistically I need to remove the entire lower arm assembly to be able not only to assess what is there, but also to be able to do whatever machining is needed to mount the contact and re-locate the guide pulley. This is what we are dealing with: |

Now the arm is mounted onto the body of the machine using four largish cap screws - unless I can undo those then probably the whole exercise is a waste of time. So I tentatively loosened then re-tightened each one - surprisingly they shifted quite easily. At this stage I presumed that there would be alignment dowels to accurately locate the arm. |
