Interesting thread. I just wonder if you would be able to use a TIG welding rod, of 3/32" diameter. Unless the Eheim shafts are actually designed to contact the impeller, I would think they might work. With Fluval/AC impellers, the shaft doesn't contact the impeller. There is supposed to be a layer of water between shaft and impeller, that acts as a lubricant and coolant.

The 3/32" would be too thin I think. The rod in the eheim does have some space for water lubrication and but is "tight" enough to keep the magnet from wobbling too much and touching the sides of the impeller hole housing. Plus then you would not be able to use the existing rubber bushings as the holes would be too big....too much wobbling all around.

If TIG SS rods come in 3mm, then we're in business!
