It’s not a good idea to balance the wheel as it is…on it’s 25 mm shaft. Bearings of this size have far to much friction so what I do is temporarily mount the wheel onto a smaller set of bearings (10mm) that have a much lower (relative) friction.
Above: I don’t have any small bearing left so we had to ‘borrow’ the pair of thrust bearing from the lower blade guide assembly.
Back in the shop and had a tidy up, here is video to show the results of my efforts to minimize wheel wobble. Before I put the wheel back onto the saw I will need to balance it again so that’s the next task.
The main challenge when mounting bearing flanges onto either side of a wheel is to minimize wheel wobble. Run out is not an issue here, that can be taken care of later. The purpose of the 4 holes in the wheel is to allow clamps to be passed through to hold the flange bearing during the gluing stage.
The wheel needs to be mounted on the workbench so I removed the lower shaft from the saw and made a temporary mount for it which is clamped to the workbench.
