Randy you already have bearings, so using flange-mounted bearings to hold a shaft makes no sense and is expensive ($30+ each) and complicated.? For free and i less than 5 minutes I make this demonstration of keeping it simple.? Bottom shaft holder is bored an inch deep to hold shaft, top is bored through, and you just drop the shaft through.? Make the mounting holes on the top block slightly larger diameter than the screws that mount it (and use a washer) and then you have a little wiggle room to adjust side to side to get it aligned properly. |
