Some days ago appeared in ebay a great Leinen MLZ4SB lathe to sell. The pictures in ebay also showed a manual for the lathe. This model is close to the type of my lathe. Thus, I decided to talk with the seller and to ask him if it is possible to send me a copy of the manual. People at der-gebrauchtwarenhandel, the Ebay seller, where really kind and they sent me a scan of the manual.
I was obsessed with those beautiful optional tailstocks built by Leinen that appear in the lathe parts catalog. An intense surveillance in ebay has given some partial results. The first attempt achieved this nice capstan-handle tailstock that admits the 25 mm 363E collets:
However, although the tailstock is in pretty good condition (just cosmetic issues) it is not appropiate to the Leinen LZ4SB dimensions. It shares the 130mm center height but the bed dimensions are not the same.
I bought in german ebay a four jaws independent chuck with DIN 55022 number 4 fitting. This was not the kind of independent chuck I prefer for the Leinen lathe. I would prefered those kind of “old” chucks which are lighter than the modern ones. Having found no provider for these lighter chucks, finally I went for this one.
The chuck can be seen in this picture:
The chuck was in pretty good condition.
An old Waldmann WD 306 luminaire is added to the Boley Leinen lathe. The luminaire is nowadays old but it is still a very good design. Can be found at a reasonable price and, after servicing it, make a very good value for money.
Some days ago Sam Kowalski, a happy owner of a Boley-Leinen lathe asked me for the dimensions of the collet’s drawbar. He is posting some nice pictures of his lathe restoration in the Old Wood Working Machines forum. Sam, here you have a handmade sketch of the drawbar ;-). Don’t hesitate to ask for more details if needed.
Beware that last informations about Boley Leinen collets for LZ4xx lathes tell that the threading is not M23x1 but a specific thread, say Z23x1, the profile of which is 55º instead of 60º of metric standard.
