The Antoni Pujantell AP lathe I have been a proud owner of an AP lathe (AP being the initials of the maker: Antoni Pujantell). This lathe is the first machine tool that arrived at home and, after many years of service, I sold it some days ago. It arrived from a scrap dealer in a bad condition: some parts broken, absolutly rusty, geometry worn out because of the use. My father and myself together spend many hours to recover it.

The milling machine Cincinnati-Chomienne FP30 This entry describes the milling machine Cincinnati-Chomienne model FP30. It has served me a number of years but now it’s on sale. Literature on this machine is scarce. I found only manuals for similar Cincinnati-Chomienne machines and a brochure for this machine that shows its main dimensions. The milling machine is built in France in the late 60’s (acording to the plate the april of 1968).

Some time ago I bougth an Isoma centering microscope with ans SK40 adaptor. However I have no SK40 machine at all.

It is a M15x0.75 threaded end with two main features: A 16mm bushing guide that assures concentricity, and A mating ring that assures perpendicularity.

Thus, I decided to build a particular square that fits in the head nose and offers a reference plane to test with the indicator or the protractor, for instance.

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).

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.
