Because of reasons, I needed to cross drill some shafts with some weird diameters. I own an old imperial Reglus drilling jig but I didn’t have the required bushings. I decided to make some of them. This post shows how drilling bushings where made.
A look inside the drive train of this vintage Wörner drill press reveals a massive modification by a previous owner. To drastically reduce the rotation speeds, an extra intermediate pulley was spliced into the system, forcing a new single-step pulley onto the motor shaft. While it’s possible this was a custom factory job by Wörner, it’s far more likely a clever aftermarket hack. Either way, it’s coming off to make room for a more traditional setup.
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…
After disassembling, the general state observed is good enough for a maybe 50 or 60 years old saw. Most of sliding parts are well fitted.
The Leinen lathe features a two-speed (1:1 and 1:8) reduction gearbox that can be operated while the machine is running, utilizing a multi-disk oil-bath clutch.
