Why do you need a lathe you say?
I bought a 14" Delta Model 28-276 band saw a long time ago, it spent the first 5 years in the box in the garage, finally got a round to putting it together about 5 years ago, there was no room in the workshop so it stayed in the garage and was only used when the the smaller band saw wasn't up to the task. It made a lot of noise and racket and I always assumed it was because it was never mounted properly.
Well today I mounted it in the shop and now the noise and vibration are much worse. The solid mounting is now magnifying the vibration. Removed the blade and it was better, still making some vibration however. Figure the problem is with the top wheel. Removed the wheel and discovered the bearing were stiff, order new ones online, 6202 bearings be here in few days. Damaged the seals pushing the old bearing out so I wasn't sure if in fact they were the problem. Thought I'd check the balance or the top wheel, got out the oversized prop balancer I found at flee market sometime time ago. The shaft for balancer is 5/8" diameter, so I set up the balancer wheels and put the 5/8"shaft through the 35 mm bearing bore on the top wheel, it was very clear there was a balance problem here. Got do this right, so now what. Push the bearings back in and all I need is a 15 mm shaft, that's why you need a lathe! Turned a piece of 5/8 stock down and when to work. The first shows the factory balance, the 2 - 3/8" diameter drills at 2 o'clock. I pocked through with a 1/2" drill at 3 o'clock. Second photo is the flip side where I used a 1/2" on the heavy spot. Balanced just like prop so it doesn't stop in the same stop.
Decided it was wise to check the bottom wheel. OK remove the bottom wheel, it has a 20 mm bore. Why do you need a lathe you ask? To make a 20 mm x 5/8" bushing. The effort to balance the bottom wheel is shown in the third photo. With the wheel mounted the vibration is improved. In both wheels the factory balance holes and mine are in the same spot, it appears they just didn't go far enough. Hopefully all works out when the new bearings arrive, I will let you know.

9 spoke precision balanced wheels. One thing for sure, they are 9 spoke!
