Does anyone in the group have plans for a diffusion pump. I have seen photo of a glass one which was made by copying a metal unit and I understand it had even better performance than the original unit. I would also be interested in hearing how these pumps work, one thing thats not readily apparent from looking at drawings is how the oil is recirculated in the unit. Any help would be greatly appreciated.
