Then look on pages 68-9 for a description of the construction a Kyrides stirrer, which is even usable down to 10 mm of vacuum    There's a design with pictures on Rhodium's page, at:

my stirrer shaft is not long enough to accomodate that (it's 45 cm, and this is for a 3-necked 12L RBF). the stirrer pretty much has to be in the center neck (due to stirrer paddle being for a 12L RBF) and the condenser is on one of the side necks.

You obviously have inappropriate/incompatible equipment and should do some shopping, rather than trying to reinvent the wheel. Such a mentality usually leads to reaction failures and/or glassware breakage.

thx for the input, y'all, but swim has succeeded with the stirrer (for now), despite the poorly chosen equipment. the improvised stirrer in

https://www.thevespiary.org/rhodium/Rhodium/chemistry/equipment/overhead.html

provided me w/ some inspiration (thx lugh) that got me through the stirring i needed to do.

on a more novel note, due to swim's friend not taking into consideration that the stirrer should be made of PTFE or glass (conc. HCl + stainless steel + hrs. of reflux -> corrosion), the stirrer paddle broke free during the reflux. swim suspected this would happen, and has decided to continue the reflux (w/out stirrer) to completion to see what comes out. swim has only another 14 hrs. to completion    (yawn!).

hopefully the clemmenson (spelling?) reduction will come out dandy (not in the British sense) irrespective of the stirring, but swim will try to UTFSE to determine that.

big money, no whammies, stop!
