View Full Version : bowl in the cave

I actually finnished the bowl in record time. Its not the fanciest in the world but it is finished to a highish standard. It is the first time I have done an under cut.

So from the begining 2:43:42pm I have a blank. That is a piece that has been prepared by being cut round

Next I mount it. It is screwed from behind with the base out and turn the outside and base first this is now 3:43:10 pm So in just under an hour I am at this point. I had a few set backs so in production mode this should have been able to be nocked back to say 35 - 45 minutes

Oh I did stop and check my email at some point and also went on my forum. The kids were playing in the saw dust and I went inside for something soomewhere along the way.

Next to flip it and hollow it out. Now I was trying a new chisel, a swan neck. This has a curve and thought would be good to get under the rim. Wowzers ... be careful with that one!!!! I decided to go to the straight one .... must say it worked rather well

These are the chisels in question. Pencil helps scale size of blade.

And here is the bowl almost finished but still mounted at 4:38:45 pm

Now inside and done ... ok I dropped it and put a dent in the bottom but shhh sont tell anyone.
Finally, 4:39:30pm, it has made it finished onto the work bench.

1 hour, 53 minutes and 48 seconds later .... from the time it landed by the tape to the time it was done. Im happy with that for what is only my 5th bowl or so.

Ubeaut ... thanks Neil, was able to finish on the lathe thanks to EEE and Shellawax. Think I should have worked the outside a little more.

Thanks Mick ... the timing was not deliberate, a benifit of info stored on photos.

I like the curve on this bowl. I have a Camphor Laurel blank which looks almost exactly the same size + shape, and this kind of bowl shape might be an option for it !
What is it about the swan neck which makes you say to be careful, lots of catches ? I am thinking of adding to my small tool collection at the Brisbane working with wood show and this kind of tool is under consideration for me.

Yeah the swan neck really grabbed, mind you so did the straight one the first time.

I think it is just the angle of aproach and getting used to using them. I am not particularly into carbide cutters but must say this one worked rather well.

In the pic the swan neck looks straightish but if you look at its shadow you can see some of the bend (just the angle of the pic)

I must say I am rather pleased with this shape, very simple but I like it. I left a 2 - 3 mm foot just to lift it slightly off the ground. I am happy with that too.

Looks good Dave, and done pretty quickly. :2tsup:
(I won't mention Brendan's 10min bowl. :D)

The angle of attack with carbide tools isn't as critical as with a gouge, but still important. Although horizontal and in line with the centre is recommended, I find that mine cut best with the handle raised very slightly. (That might just be my cutters, and not relevant to other brands.) Also, I've found that when working with hard hardwoods, it's not a bad idea to sharpen them at the end of each day. Nothing like starting the day with freshly-sharpened cutters.

That swan-neck tool looks interesting. In the photo, it looks like the cutter is at 45 degrees to the curve, like it's set up for shear scraping.

What brand are your carbide tools, ('Easy' maybe?), and what diameter are the round cutters?
I'm using a Sorby Turnmaster, and find the round cutter a bit big for some things. Your's look better for small radius curves.

This time next year I may try and compete with the 10 minute bowl :)

I found these cutters work better as a shear scraper.

Not sure what cutter they are. They must have a radius of no more the 10 mm. Worked a charm. Not sure how many bowls I could get from one cutter.

These are home made by a guy in the States. You are right. It seems the swan neck is made to shear scrape. The other one I used straight across the bottom and in shear under the rim.

Thanks, Dave. Now that you mention it, I vaguely remember seeing some similar cutters on eBay a while ago.
Do you by chance have a link to the supplier?

I've heard you can get up to 40 bowls from a cutter, but I reckon that's if the wood is softwood or green. Mine are noticeably blunt after a couple of hours on well-seasoned old hardwood. A touch-up with a diamond hone helps tremendously. I spin the cutter and hold the hone against it, (a DMT 600G Dia-Sharp credit-card hone).

I will have a look around. I did have some links to various suppliers at one stage. It dues work very nicely. Getting a flat bottom was a breeze.

Any deeper and I would probably have angled the rest into the bowl.

Yeah the swan neck really grabbed, mind

When using an offset tool with a swans neck, it is important to over have tool rest back far enough so that the contact of the tool on the rest is only on the straight part of the shank.

Any attempt to use the tool with the curved part of the shaft in contact with the rest will result in the tool wanting to rotate into the wood and will lead to a dig in.

Hope of use to some.

Cheers

Tim:)

Thanks Tim

Had my woodturning club meeting last night and someone else also suggested that could have been a factor. Likely it was. I will pay more attention to overhang and what is resting on the rest next time.

I'd press like but don't have that option on tapatalk

Hi dave,
That, s a nice looking bowl mate,
did you just want to try out the new swan neck
as you could have done the inside with a gouge
or even a scaper, either way it looks good:cool:
(I see you have given up on the spirals)...:o
Well done on the bowl looks good
Cheers smiife:2tsup:

DaveTTC
26th April 2014, 08:49 PM
Thanks Smiife,

the spirals will be back!!!

Yeah I have never done a hollow form and thought it would give me some practice while I can still see what I am doing.

Oh I have no decent scrapers to speak of

Nicely done on the bowl. :2tsup: Keep up on making them and you will get faster.



....(I won't mention Brendan's 10min bowl. :D).......

Now to be fair it was a smaller size bowl. :U I watched the video and it was interesting to see how quickly one can be made. It gives me a perspective on what to aim for.

Yeah, I was just having a dig. Dave's doing very well, and much better than my 10 hour (and 10 day) bowls.

You are not turning enough.

You're right about that, I've caught the segmenting bug - 90% prep, 10% turning.

DaveTTC

Have not done my own segmenting yet ... did one from a recycled chopping block but that was not my own segmenting. Was a cheap blank at $1, got a platter and a shallow bowl from it

You should give it a shot sometime Dave. A heck of a lot of preparation, but very satisfying and the results can be pretty impressive. (Not necessarily my results. :D)

I'm just about to finish the bottom of my second, might post it when done, and in the midst of making the rings for my third, at one ring per day. (The 10-day mission.)

I have been toying around with the idea for a while. Even Brendan would not turn one of these in 10 minutes if he went to the trouble of segmenting
