welcome back. as i said in my previous video, i'm goingto turn a bowl using my lathe equipped with an adjustable chuck, as well as the tablesaw. for that i will use these pieces of olivewood obtained from mediterranean olive trees, which are pruned yearly.
woodworking router lathe, first i'll glue the wood like this. once it's dry, i'll cut it with the tablesaw to obtain the desired thickness and end grain, which gives it a more ornate look. i apply glue again making sure the cut linesin the wood blocks don't line up.
now i'll mark the outer diameter to cut withthe band saw. using the same center, i will mark the diameterof the faceplate to place it in the center. i screw it in and put it in the lathe to startthe machining process. since the bowl is quite wide, i will use theslowest lathe speed and a roughing gouge. olive wood is less than ideal for turning. it is quite hard and its grain swirls, andsince we're turning against the end grain, this is made even more difficult. still, little by little i turn the bowl intoshape. i'll mark the center with a small protrusionthat i will later use to hold the bowl on the table saw.
i'll also take the chance to sand the bowl'sexterior. before removing it, i'll mark the center ofthe bowl on the bottom with the tailstock. i've marked a square on my table saw to help me place the bowl and i've prepared this template to machine the interior. we must make sure the center is marked properlyso that the disc doesn't cut through the bowl at any point. it could be dangerous if that happens. i move the disc up gradually, in 3mm increments,making each cycle slowly. every so often i will detach the templateto see if it looks good and wipe off the sawdust. using a good chuck, we could machine the bowl on the lathe.
i thought about making one, but i believeit's too complex to make. besides, it would be very dangerous if itcame loose. that's why i've decided to buy a chuck which i'm going to adapt to my lathe's shaft. now i'll attach the adjustable chuck on the lathe and put the bowl on it. to center it, i'll put the tailstock in thecenter of the bowl again. i tighten the silent blocks gradually andmake sure the bowl is firmly held. i finish machining the bottom part of thebowl, making a little rebate to avoid unsteadiness when putting it on a table. i will also fill in the cracks on the exteriorwith a little red epoxy and take advantage
of the rotation to do a little more sanding. i'll fill the cracks on the inside with blackepoxy i also apply a little mineral oil here. the end grain on olive wood never ceases toamaze me. it's hard to work with, but the result morethan makes up for it!
