Last week I decided to do a little work with the Picador Pup. The motor is installed, the drive belt free, and the bearing all oiled up.
Note for younger readers: bearings in modern tools are sealed at the factory with unimaginably sophisticated lubricants that last for decades and never need replacement. I am starting to think this applies to a lot of motor cars too, but that is another matter.
Old workshop machines need constant lubricant replenishment. You need to check before you work and after a certain time to top up the reservoir – this is because the tolerances between the moving parts may be very loose. If you do not there is an almighty squealing and all movement stops. That is why they make beer in stubbies. I believe it may be the same with the actual machine tools as well…
Working away I started to hear this irregular screeching noise. It got louder and louder and I wondered if smoke would pour out of the Pup and everything jam. Then the screeching got quieter, and went away. It was only when the Tail End Charlie – the last in the flock of White Cockatoos flew past the open door ( Squawk, squawk, squawk! ) that I realised I had been given the bird.
At least they are just an intermittent thing – some of the other wildlife in the workshop visits all too often. The underside of the workbench is a big open space that venomous red-back spiders seem to find attractive. As my bare legs also fit under the bench top it is a good idea to evict them periodically. I use a can of insect spray rather than a flamethrower.
The other hazard is just the fact that in Australia, summer is practised upon a professional basis. If you do not get your work done by noon, you won’t get a chance to do it again until 8:00 PM – the rise of temperature inside the closed space renders all efforts impossible. I find it is good management to arrange gluing and painting between 9:00 AM and noon because the heat of the afternoon will set things perfectly. As long as you can ensure no currents of air or dust in this period, you get a baked-on finish with most acrylics and enamels.
