The boka that i have (one of the alcoengine reflux stills) I often think of as 2" because I sit it on top of a 2" ss spool, but its actually 1.5". I have several extra spools, including a couple 12" sections and im considering turning one of these into a boka head. Will the increased speed be worth the effort of making a new head and condenser?
I have a few reasons for wanting to do this-
1. the alcoengine isnt a slant plate style, it has a 90deg elbow (fairly small, too) facing upwards inside, and i suspect that a lot of the reflux misses the target. Even with the valve wide open on a stripping run the abv seems higher than it should be, and takeoff slower. (This first issue has been obviated by getting a potstill, which im waiting to arrive, but its illustrative of the idea that i think the design isnt optimal)
2. faster would be nice
3. If I had a newer, bigger, better boka, i could send this one to my brother who has expressed interest in distilling but needs a bit of a push to get going.
4. My boiler is 2400w, which seems overpowered for a 1.5", but more suited to a 2".
How much increase in takeoff could i expect? Ive read somewhere around 56%, which would be substantial. One of the parent site calcs seems to confirm that. Does it really work out to be that much in practice?
Worth the effort?
