Spent some time on the sugar maple mexican pot today. I reverse chucked the turning onto a vacuum chuck and turned the tenon off of the bottom.
The piece was then sanded all the way through 320 grit and then removed from the vaccum chuck. I build my own vacuum chucks using PVC pipe and attaching closed cell foam to the end of the pipe. I turn a plug from Trex wood deck material, drill it and then use a threader to create threads to fit my lathe. The plug is glued into the headstock end of the PVC pipe. I have a variety of sizes and lengths of these homemade chucks and if needed can custom make a vacuum chuck.
The piece is now ready to be closely inspected for any minor flaws and hand sanded as needed.
I will use a mixture of 1/3 high gloss poly – 1/3 high gloss tung oil – 1/3 mineral spirits as my finish for this piece. Will go with at least 6 coats, let it dry for a couple of days and then buff it out. Will post photos of the finishing process. I will now start on the next piece to be turned from the big stuff sugar maple turning project.
