I had SN2 chucks but found issues with the limited jaw opening compared to the Strong hold. I normally turn tennons to hold the bowl blank with the chuck. I found during the drying process the tennons shrink so much that by the time you true up the tennon, the SN can’t grip it to final turn. There is a lot more travel with the Stronghold. I have since finished those bowls with the Stronghold Chuck. It might not seem like a big deal but I turn a lot of burl.
I am sure there was a better fix for my problem but the Stronghlod works for me.
