Clausing 5914 -- removal of 5C collet holder
I finally got the 5C collet holder out of the 5914 spindle. The
approach was a combination of using the aluminum spindle nose protector to put pressure on the holder and a piece of 1" black iron pipe from the back, hit with a big steel hammer. What gives on the nose protector is the threads, I think. The first few threads on mine are broken off, and have been that way for some time. The holder was caught by a wooden dowel held in the tailstock chuck, with a rag tied around the dowel, thus protecting the ways and the holder. Joe Gwinn |

I've never had problems removing mine with just the nose piece, maybe its time to rethink methods before mine looses threads.

Joe Gwinn Is your collet holder a 4 1/2 MT - 5C adaptor? If you could, would you post a few views of the nose protector? I'm going to need to make one as soon as I get my lathe going. I'm assuming you have a L00 spindle. I have a 6903 that I'm currently rebuilding the vari drive sheaves to get the original system working. Sadly, I've not made a lot of progress recently but I'm going to get right on in again soon. http://wess.freeshell.org/clausing/Clausing.html Wes |

Joe Gwinn Is your collet holder a 4 1/2 MT - 5C adaptor? I have no idea. How would one tell? It is a simple steel sleeve that accepts 5C collets and sits in the female taper of the spindle, and has no involvement with the L00 taper. Is that female spindle taper MT 4.5? I guess that's the implication. If you could, would you post a few views of the nose protector? I'm going to need to make one as soon as I get my lathe going. I'm assuming you have a L00 spindle. I can photograph it, probably this weekend. I don't think that the dimensions are critical, except for the part that mates to the L00 taper and thread ring. It might be useful to make the threaded part longer, to aid with removal of the collet holder. I think too much stress ends up on too few threads with the current design. Maybe make it of steel too. I do have a L00 spindle. I have a 6903 that I'm currently rebuilding the vari drive sheaves to get the original system working. Sadly, I've not made a lot of progress recently but I'm going to get right on in again soon. http://wess.freeshell.org/clausing/Clausing.html This might be a good candidate for reworking the lathe for direct drive from a VFD-controlled motor, as described by Paul. His photos are in the dropbox, at 5904_vfd.txt et seq. It could be less total trouble than repairing the assembly (which costs $800 from Clausing). Joe Gwinn |

I already have bushings, moglice, and other stuff to fix it so I'm going to continue on my current path. Thanks, Wes |
