Jones and Shipman 540P Rebuild (Round 2)

[dephill]

Really interesting thread, I only wish I had enough space and time for a machine of this calibre.
This process sounds particularly fun:

Once these are removed a genital tapping on the end of the shaft where the dial has been removed will push out the system.

Thank you to the creator and all subsequent contributors to this thread. Its been a really excellent read, by far the best on the 540.

I have been stripping cleaning and repairing a 540 for a couple of years now and very enjoyable its been too. But now I'm down to the last and heavy bits, and could do with a little more guidance if any one can help?

Must the wheelhead carrier be removed vertically from the column, before removing the column from the machine, OR, can I remove the column assembly from the machine, lie it on its back and then lift out the carrier from the upward/open side ?

I think Kaiten said earlier he lifted the carrier out vertically, without a crane. Just wondering if you could say a little more about how you did this ?

If any one knows the weights of the carrier and column that might be useful information too.

Might be a bit late to add to this thread but many thanks to deema for his detailed info, helped me immensely as I progress down the same road..!

Progress so far..

SimonP - looks like we are running in parallel!

I keep researching how to scrape the ways back to ‘factory fresh. Mine are OK, but not perfect. The problem I can’t get my head around is how to reference the ways to get them parallel and level. Would really appreciate advice of how to do it from anyone experience.

Same here, where does one start..?

Nice.. you're a way ahead of me though..!

Regarding the ways.... mine actually looked pretty good, so decided to finish rebuilding the machine then do some machining accuracy checks. If then I don't like what I find, I will think about the correction, and how to do it. Taking it apart a second time will be a piece of cake now that its clean and I know where all the 'secret' bolts are!
