Refurbishing the Boley Leinen lever tailstock (I)

September 4, 2016 in projects

The tailstock Some time ago I bought an old series Boley Leinen lever tailstock to be fitted to my lathe. This is the tailstock: It is of the old type because it uses a split casting to lock the barrel as you can see in the picture. Leinen buid two flavors of this tailstock: one with a barrel that takes 363E collets (the 25mm collets) and other that takes the 323E collets (15mm collets).

Boley Leinen LZ4SB lubrication

August 15, 2016

The lubricants to be used After translating the oil tables that appear in the Boley Leinen datasheets to ISO grades, and according to my oil dealer, I ended using these oils: Spindle oil: Renolin MR 1 (ISO VG 5) Gearbox oil: Renolin MR 20 (ISO VG 68) Grease: Krafft Lithium grease NLGI 2 I want to add some notes about lubrication: Renolin MR is a detergent oil. This helped to clean the gearboxes from the old sludge.

Klaiber WS2 collets

January 17, 2016

Which are the collets that uses the Klaiber WS2 tool grinder? I found the answer few days ago while looking at ebay.de. A seller was offering a Klaiber grinder. In the machine pictures there was this one: It is a 6mm collet for the klaiber. The picture has the answer!! Klaiber collets are of type 317E. It was a non usual collet size. I have not found any provider offering it.

Boley Leinen LZ4SB and MLZ4SB manual

September 13, 2015 in library

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.

Klaiber WS2 universal cutter grinder

September 2, 2015

A new guest The garage has a new guest. It is a small universal tool grinder. A Klaiber WS2 maybe of the last models built by Lechler. Below, there are some pictures. As you can see the overall state is good. Finishing is original. I only appreciated a very slight wear in the table lineal bearings. You guess it: the table of this machine is supported by lineal bearings. I think this is not very usual on Klaiber machines.

Looking for these beautiful Leinen tailstocks

August 31, 2015 in tools

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.
