Just a Question. Does it matter if the coil condenser is a firm fit in the column (actually touching the sides) or should it have some clearance. To me a firm fit would help make it stay central in the column. Cheers

To my way of thinking, the more places for the vapor to flow through and contact the condenser coil the better. No tight fit. What's the point in cooling the walls of the tube that the coil sits inside of (the upper column walls)?

Make it with clearance and if you then need or desire a tight fit, stuff some SS Scrubbie around it. If it is tight to the sides, it can cool the column and the take off port.

2 ways to look at this. If it touches the wall that section of wall becomes another cold surface and becomes part of the condenser. However, as has been mentioned if that is too close to your take off point this can have a negative impact. It depends on the configuration of the column and condenser.

Thanks Myles How close to the take off point is too close Cheers
