Guys, I'm relatively new to wood turning as I've been doing it for about 5 years now as a hobby. I have a Jet 1221 and a few Nova G3 chucks. I've been mostly turning bowls but I have a few pieces of oak from our property that is about 4.5 - 5" in diameter that I turn into 5-6" high vases with some bark left on it. Some of the wood has a bad center, ie soft wood in some areas which makes it impossible to use a wormwood screw on it like I normally do. I've downloaded Teknatool's Chuck Accessory Jaw Travel Table from their website a while ago. According to this table, the largest jaw set I can use on a G3 is a 100mm jaw set that has a maximum contracting spigot of 3.898". The 130mm jaw set on the Supernova 2 has a maximum contracting spigot of 5.039". However, the table says the 130mm jaws are "Not Recommended" for the G3. My understanding is the 130mm will fit the G3 and I plan on turning the speed down to about 500 rpm. Is the G3 just not beefy enough for the 130? Too much mass? What are the risks of using a set of 130mmm jaws on a G3? TIA!
