I have just made this and it works a treat, air bubbles as per pic are now much finer. I only have a single speed drill so I had to trigger on and off to prevent the wine from swirling out the fv. I will now leave a further 24 hours before bottling to ensure any sediment that may have travelled through the siphon tube has a chance to settle again.:whistle:
Glad it worked, here is my version -
