« Part 2: Open form in oak, day 1 Part 3 of Projects, the backstories series Part 4: Cane in mystery red wood »

I didn’t want the first entry to be too long, it was War and Peace just for day 1.

So, here’s the rest of day 1 followed by day 2.
It’s really just hollowing mostly…hollowing, hollowing, and more hollowing.
I stopped the first entry at 9:06 p.m. at about 2 inches depth.
9:14 p.m. It’s not brain surgery…a long handled, a study tool rest, wood hitting the cutter head, me hanging on the back of the handle.

Down to 4 inches in 8 minutes. The Sovereign can really chew some wood.

And fyi the blank is 13 inches deep.
9:24 p.m. another 10 minutes, deeper in but now the Sorby isn’t able to track along the inner wall. The tool is working fine but I don’t have the articulated link in, so the edge of the cutter can’t get to the wood.

So I put the articulating link back in and put a slight left angle into the tool.

9:44 p.m. Working the angle on the tool between straight and left I got a lot more chewed out.

Down to 6 1/2 inches.

9:55 p.m. Finishing up day 1, a lot of wood on the shop floor, and cabinets, and shelves, and me. A good portion of the blank to a reasonable thickness ~1 inch for drying.

General outside form. Will turn the top more narrow as warpage allows.

9:57 p.m. The scene of the crime. I hung a sheet on behind me to keep shavings from the outer turning from drenching the workbench and stuff on it. Shavings about 3-6 inches thick on the floor. A nice light smell of oak sap in the shop.

10:01 p.m. Trash bag wrapped around blank to stop uneven drying overnight. Turning the lights off.

DAY 2

I don’t seem to get into the shop before the afternoon most days. Reading email and forum posts. Surfing up ideas, tips, and tricks, playing a couple of games, then lunch.

So about 2 p.m. I was back in the shop. Side note. I use my Samsung Note II phone for most of my photographs right now. It’s always in a pouch on my left hip. And it takes pretty good pictures. And I try to take a picture at the start of a project, and when I stop/finish/switch to another so I have an idea how much time I spend on each phase and each project.
Wouldn’t you know it, I was so eager to get started that I forgot to get a start time picture.
2:44 p.m. Hollowing continues. I’m at 8 or 9 inches by now and the Sorby is really starting to bounce. The tool rest is right next to the top of the form, but the cutter is WAY past that. I’ve got the end of the tool handle under my armpit. At least it’s not really catching, just the changes in wood texture and density make it seem that way. I’m getting bruised under the arm I think.

Finally deep enough to put the bowl rest in. MUCH less vibration, very smooth cutting again, and much faster.
2:48 p.m. Tremendous progress with the bowl rest in.

Hollow hollow hollow, stop, blow out shavings, repeat.
5:45 p.m. took a break somewhere in there for supper. Hollowed out as far as I wanted before drying.
Entire form is about 1 inch thick.

A nice thick cushion of shavings on the shop floor.

6:34 p.m. Dismounted, found a box to pack it in.
Stuck it in the back of the shop. Will weigh it later and then start tracking weight loss until it stabilizes. Then will see what warping and cracking have occurred and will see what I can do to finish it up.

This will be a very good activity to watch seasoning wise.

That’s some bowl you have made there !

Joke: You could paint it grey and sell it to the Navy as a radome!!

It might have been a good idea Pete to pack roughed bowl in the shavings to slow down the moisture loss to reduce wood movement and cracking.

Lol Mike,
I actually had that discussion before we packed the piece up for drying.
I did a little surfing around and came up with sawdust and paper bags as options for a poor man.
Since this is a practice piece I thought I’d try the closed cardboard box as another alternative.
My thought process was…
Since the box is almost completely closed it creates a homogenous environment. The air gaps around the wood will maintain a consistent humidity because it is a contained air mass.
The relatively small air mass will quickly reach 100 percent relative humidity and maintain that as long as the wood is above ambient humidity.
The low permeability of the cardboard with greatly reduce the loss of moisture from the inner air mass thus providing for a slow and controlled loss of moisture. The cardboard box is a U-Haul moving box that has very little printed area on the outside. I had a bigger box but it was covered in paper decals that looked like they would greatly restrict movement of moisture through the walls.
If it does crack I’ll try some type of recovery method (crushed stone, sawdust, metal filings) to fill the crack, or just leave it as is.
And if it stays wet too long and starts growing things I’ll just call it a spalted oak!
