Boley 4LV
RotarySMP:
That really was a special order spindle wasn't it. Din 3? Is it the short taper from Camlock, but clamped up with nuts on the rotating kidney slotted disc? I thought that was DIN 55021 Type B? Nice to have for sure. You really got lucky with this lathe.
Concerning the retracting tool holder, I would suggest you join the Boley subgroup in the CNCEcke.DE Forum, and ask there.

Mine came with the Boley 4 way tool post, but I use a Phase II AXA on it.
I have the original Klopfer 110mm three jaw, which is great with the outside jaws, but someone turned a step on the inside jaws. Good for thin parts, but hopeless of small diameter stuff now. I bought a replacement Klopfer 110mm marked "Weiler" hoping the jaws would be interchangeable, but they aren't, and the second chuck has more wear. Also picked up a low mileage Bison thin lightweight 125mm four jaw independent. Nice chuck. Unfortunately I currently only have one backing plate, so it is about time I get stuck in and make a dummy spindle nose gage with the M40x3.5 x 55° nose thread, and then make some more backing plates, face plate, catch plate etc.

Made a little more progress on scraping in the compounds flat ways.
There was a hollow in there which has taken a fair bit of work to get done to.

Some pictures of head stock and chuck
The scroll only moves just under 1/3 turn and then the jaws can be withdrawn , There is a detent to hold each jaw is place for location purposes
The jaws can be fitted to different places in relation to each other .
Each jaw can be independently reversed
There is a small button on the front of the chuck that comes out to indicate when the scroll is fully withdrawn and the jaws can be withdrawn
Forkardt still make this chuck and when I have a few pennies I will buy a new set of jaws as at the moment I only have soft jaws but at £365 a set it will have to wait
The chuck is rated at 4000 rpm
A new chuck is eye wateringly expensive

Hi Mike. Tasty chuck!
I hate to think what that lathe would have sold for new. A standard 5LZ in 1970 had a list price of 70 000DM, which wasn't far of the price of an average house. Your special order spindle would have pushed that up a fair bit. does it have metric or imperial leadscrews? That would be a wonderful machine to restore.
Edit [Deleted the bit about the spindle]
Might be a good idea for posterity, and future 5LZ owners searching for info, to post all your photos on your 5LZ thread and I'll post the 4LV stuff in this one. There is not much info on either on the net, so it might be helpful to keep it sorted.
Yesterday I cleaned all the compound slide components. They are in very good condition with little wear. The lead screw and nut look as new. The castellated nuts haven't been mangled with a drift like all the other ones on this machine. Photos are still in the camera sorry.

I finished the flat ways of the compound. According to Conelly it should have 10-15 ppi, and I count 14, so I hope it's good enough.
The tool post mount surface is a bit sloped. I'll need to take 0.2-0.3mm off it to get rid of the impact marks.
The cross slide also has a bit of wear. I'll have to do scrape down carefully, as the compound mount boss is pretty good.
