I’ve got two of those title turbines ordered too. A company called baca bearing makes orsupplies lots of model bearings. I’ve dealt with them in the past. With success.those turbines have pretty small shafts. I had tre finding couplers. I may ha to mak bushings to use the couplers I do have. Thy are model boat things but I don’t realy think they will hold up to the speed these little things make. I’m considering a gear box so I can make my own couplers. Maybe a spring cooler or rubber tube might be betttrr. M actually planing on using these ss oil separators. To strip oil out of the ar. Then have it go to a filter dryer. Something I can test out. The order says at lease three weeks so it may be spring weather by then.LOL.
