Are they used on different 'era' machines ? What is the difference

Early 102 trays had feet ( lugs )so that the tray didn't rotate , to this end the motor board had two studs to stop the tray from spinning later machines without the studs had trays with no feet , during the war trays were discontinued due to metal shortages
The first machines only had the automatic brake which I guess may have disengaged when carrying ?poodling around wrote:Thank you soundgen.soundgen wrote:poodling around wrote:I think that some HMV 102 record trays have what are called 'lugs' and some don't.

So, were the feet no longer required because of some gramophone design change or did those later ones without feet just spin around when the gramophone was transported ?
Yes the later ones did just "spin around" when the machine was carried, but because the two curved "upstands" were heavier, the whole thing only spun to a vertical position within the case. The carrier couldn't fall off, because the lid almost touched the sides of it. When we say "spin", that doesn't mean the turntable was going round, the brakes stayed engaged in all cases. It simply means the carrier moving rotating on the centre spindle.poodling around wrote:So, were the feet no longer required because of some gramophone design change or did those later ones without feet just spin around when the gramophone was transported ?

To stop the carrier full of records spinning on the centre spindle, and marking the lid!soundgen wrote: So what was the point of the legs and studs ?
