The drilling press was modified by a previous owner. As it can be seen in the picture below, someone added an intermediate pulley in the driving train to reduce the rotation speeds. What was the motor pulley became the intermediate pulley and a new single step pulley was fitted to the motor shaft. I have some doubts about the origin of this variation: would it be made at the Wörner factory after a specific requirement by a client?

Some of the parts of the Wörner B13 were originally blackened. Rust have ruined most of those finishings. Thus I was faced to polish them to clear metal or try to recover original black coating. I found interesting to experiment with those cold blackening solutions and give them a try. What follows is the resulting experience. The parts to be processed were: The screw plug of the quill retention. The handle and bearing support of the belt tensioning pinion.

One of the jobs done this summer is a special square intended to facilitate the alignment of the grinder axis. I own a Klaiber WSII tool grinder. This grinder has a head with several degrees of freedom and aligning it to the table is not easy given the poor quality of the head scales. 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 work on the power hacksaw is slowly moving forward. The saw was completely disassembled and cleaned. It was really dirty, full of chips and old grease. Just to show the state, look at the cutting fluid tank absolutely full of chips. The last owner shouldn’t be very proud of it… An extremly dirty cutting fluid tank of the hacksaw After disassembling, the general state observed is good enough for a maybe 50 or 60 years old saw.

The Leinen lathe comes with a two speed 1:1/1:8 reduction gearbox that can be operated while the machine is running. It works by using a multiple disks oil bath clutch. We disassembled the gearbox to check its condition. The reduction has a very thick deposit of oil after years without maintenance. Disks are in good condition and shaft seals are a bit worn. The following image shows the reduction set of parts after unassembling it.

After being adjusted, the compound rest shows two issues: The motion screw exhibits a play that cannot be decreased. Provably the adjustable nut is severely worn. The crank has a fixed friction point when turning. No hints about the causes. The compound rest has been dismantled and thoughtfully cleaned. First it was necessary to make a special socket wrench for the adjusting nuts of the compound gib. Next picture shows the wrench.
