Hopefully this is rare, but I know it is not unknown.

Most forum users want to get along with others, even if we disagree at times.

Thread: Mini traction engine and baker fan
10/03/2021 13:50:35

Some years back at a steam rally I saw a sream engine connected to a large drum which in turn had a brake band around it which could be adjusted to alter the load, I never noticed if there was any sort of metering device.

Unfortunately I can't see the photo I assume is in your second post, but the Baker Fan is an interesting and unusual adjunct to the engine.

Baker had not been all that original though, even if the application was novel.

A fan as a test-load uses the principle of the Fly, developed by the earliest clock-makers to control the rate of the striking train. The world's oldest working clock, displayed in Salisbury Cathedral I think, is so fitted. (Clocks of that era had no dials, and were mainly for announcing the times of church services.). In later centuries the Fly, driven by a reversed worm, became used as the speed regulator in musical-box movements.

A common alternative for testing engines was the Rope-Brake Dynamometer, which uses a spring-balance or calibrated weights to measures the torque while applying the load. A subsequent development was a hydraulic version - a torque-convertor with its output connected to a spring balance.

Nice work David but if it was mine I would have to change the fasteners for hex head think they would improve the look of what is a very nice boiler a little more yes

Thread: You think you have trouble starting your car on a cold morning?

I remember back in the 60s still living with my parents in Brum being woken up every morning by a builder trying to start his Ford Cortina estate, it just churned over and over for what seemed eternity. From that day on I have always contended that Ford were pioneers in long life batteries.

Bill D.

I had same problem went out house at 5 a.m when on 6-2 so didn't like waking neighbours so I fitted a 6 volt HT coil and a resistor but when starting the coil was fed with 12 volts this cured the cold start problem.

Thread: Using a vfd for two machines
20/02/2021 15:28:54

A pair of electrically/mechanically interlocked contactors comes to mind other ways could be a rotorary switch, vfd feeds a 4pin socket into which you could plug machines into as and when. If it was me I would go with the contactors and interlock these with the vfd to make sure the load could not be disconnected whilst running.
