Hello,
I have discovered about 0.030 axial play in the arbor cradle. My research shows that there are actually shims made just for this. My question is which is the best type. The arbor cradle is cast-iron and the elevation rotating pin is steel. The mating surfaces where the shims go are each cast-iron.

It appears the shim options are brass, aluminum, stainless steel, and steel. Also the types of shims are stackable and laminated. What would you recommend?

Thank you.

I’d go brass if the parts move or stainless if they don’t.

The only movement that happens is rising and lowering the arbor through an arch to raise the blade up and then back down.

I tend to like brass as well because it is soft but I am afraid it will lose its thickness.

I’d be more worried about replacing permanent parts than shims if you use stainless. If the shims are shaped like donuts I wouldn’t worry about it.

Then it sounds like it will be brass the. You bring up a very good consideration. Worry more about permanent parts version disposable parts.

I am glad I asked. Thanks for your input Fridge.
