I built this feeder using an electric engraving unit . A piece of lay flat hose was used between the hopper and the feeder . The hopper was made to be removable . It cannot be seen on the photos but there was an adjustable plate on the feeder to control the rate of flow . There was also control on the electric needle , for the flow rate .
I no longer have this unit .
You can get a good vibrator for less than $100 . Look under concreters supplies .
