    Default Turning a walnut bowl - FAIL!

    I had just completed turning a bowl this morning which turned out pretty good, so I decided to setup the camera to film the next one. For what appeared to be a pretty plain jane piece of walnut was actually nicely figured with plenty of chatoyance. God did a good job of growing that tree. I did a bad job of turning it into sawdust....

    It seems that drilling a 8mm hole for the worm screw deep enough to also act as my bowl depth guide is a bad idea.

    "What if I remove 10mm off the bottom to steer clear of a defect???".
    Well the answer to that question may seem obvious to the time served pros. But I am not one of those..but at least now I know the answer.

    Next time I will just drill deep enough for the worm screw and then drill it deeper on the lathe once I know how much material is left over after turning the bottom.

    It can be saved make a plug in a contrasting colour to fill the mortice and make a feature out of it. You certainly are not the first and will not be the last I did one like that a couple of weeks ago

    Yes, I am going to glue a piece of Maple onto the bottom. The sides of the bowl are still about 10-11mm thick so it can be salvaged.

    Change the title from 'fail' to 'opportunity to create unique piece'

    I think if I just stick a piece of maple to the bottom it will look funny. So I will have to stick maple to the bottom and the top and that will be balanced, if I can find enough timber to do it. Though doing that makes it more work to get it mounted back in the lathe with the 10mm thick walnut section running true so I don't end up with 1/8" walls. I'll see how I go, but I'd be giving odds on that it will just be another fail.

    Kuffy,
    There's nothing wrong with it.
    You are the problem it's a design feature.
    You need to see past the hole to see the space.
    Bring it along to a Melbourne gtg and we can all tell you how unreal it is.
    Or take it to Gabs place this Saturday.

    Cheers Matt

    Kuffy, it's very hard to respond to this one without appearing a PITA.

    The lesson is to always measure. I can say that I've had teachers all the way through such that I've never been through the bottom of anything. Close though!

    As the guys have mentioned, there are a range of fixes. The tricky part is hiding them so that no-one knows the difference. Once, I gave a mate a pre-prepared blank of a Vic Wood off-centre rectangular box and he went straight through the bum.

    At home, I made an almost flawless under-cut plus and guess what? Col went through the bum again!\

    It was a waste of good bird's eye redgum but an instructive exercise. So don't be too hard on yourself. Mistakes? All of mine have disappeared into the fire.

    LA LA LA LA, I'm not listening

    It was broken, so I fixed it! It's a pity I don't do the same thing with my car...

    170mm diameter x 70mm high. Myrtle and Walnut. Shellawax finish.

    I received a few comments on facebook and a phone call about certain things I was doing.
    - adjusting the tool rest while the lathe is spinning. It's bad. I know, the gloves I am wearing were brand new yesterday, now they will get into heaven because they are very holy.
    - presenting the gouge with a fully closed face rather than rolling it open to 45degrees. I noticed this myself after watching the footage. It's good to have video of your own processes.

    Good save, Kuffy. It's tough to toss good looking wood when it looks like you should, but this case wasn't so. You had an opportunity for a design change, and it worked out. Again, good save......

    One thing I would have done differently is I would have kept the tailstock engaged until I had the ID of the recess established, then remove it to clean up the nub. Other than that, it looks like you know what you're doing, and will be turning for a long time. Have you busted your knuckles on those nubs on the jaws yet? ............ Jerry (in Tucson)

    I was pretty careful when sanding the bottom with the cole jaws. Always sanded with my fingers pointing away from me so they dont get snapped in half. I kept the gouge well away from the nubs as well, ill hit it one day and put a hole in the ceiling or my jaw

    Very nice save on this bowl.

    My thoughts were on the line of just adding a plug. Would not have done anything for the top of the bowl but you have managed to make this a very unusual piece.
