A friend of mine dropped off a failed magnolia core (funnel) he had in his shop from a while back when he was learning to use his coring tool. He asked if I could fit an insert into the center and make something out of it. I want to give it a shot. It's 15" OD so too big for my longworth chuck. The top face and outer rim have been trued up and are still true. He can't remember exactly how he mounted it to accomplish that but likely some combination of jam chucks. The trick I face now is to true up the center opening and enlarge it to a point that the thickness is sufficient to glue in a different wood insert and then proceed to turn to complete. It's very thin near the edge of the center opening. The bottom is not trued up or flat. I could try and mount and turn down to just small enough to fit in the longworth chuck but want to keep that as a last option. Would still need to get creative on a jam chuck setup to do that. I've considered hot gluing the top of the rim to a large thin blank and taking it very easy and slow on the center opening. Looking for ideas on options. I currently have a 3/4" piece of plywood centered and mounted to my faceplate that I can use to hot glue it to. Just uneasy about the hot glue holding it I guess.
