Why It's Better

[joe greiner]

Why it's better to finish turn the outside and the inside in a single session.:-

I could see and feel the wobble as soon as I re-mounted it for hollowing. But I thought I might be able to sand away the minor irregularity, or leave it alone. And, I suppose I could have stopped to increase the depth of void-filling epoxy and coffee grounds, from the inside where the cavities were exposed. But I didn't. No, I just plowed gently into the intact parts until I heard a noise.:oo:

I cut off what was left of the undercut rim, and collected most of the fragments for the wall of shame. I numbered each subsequent crack and taped everything more or less together. Wasting some CA didn't seem superior to the masking tape, in a quick and dirty value analysis. The top wall of the funnel/doughnut is closer to 4mm.

There's still enough of the blank to make a shallower bowl, or a dish if necessary. Cedar, about 10" (250mm) diameter.

Cheers anyway,

It did get rather thin Joe... just on 1 mm. I guess it gives you a chance to develop your "recovery" skills.

I tend to err on the side of having it a bit thick.... but my walnut plate almost ended up like your bowl chasing a bit of tearout. Then there was the cypress tumbler that the bottom fell out of :doh:(luckily, it was only a small practice piece)

You certainly would not want that to happen to a $100 timber blank:oo:

'Twas free wood, so no heartache there. And plenty of it left for some new blanks.:)

I was probably pushing my luck with my third or fourth undercut rim, as the "first" project of the new year - intended to be a give back for the timber donor; maybe, maybe something else.

Can't win 'em all Joe:no:

Life goes on!:2tsup:

Your first statement is true, Joe. Turn to finish, and let the wood have it's way. :D

[Chipman]

I always try to turn to finish as well.... only problem is if you are turning green wood. You have to remount it when it is dry to complete it. I have some redgum drying at the moment...it is too wet to even sand with 80 grit. It will be interesting to see ho much it has moved by the time I remount it. I have a small dish turned from some crutch timber and it has moved so much, you could never remount it. But the grain is pretty and it makes a nice discussion piece. gives a bit of character:D

Nice bangle, the new jigsaw bangle is all the rage among the fashion conscious :D

Been there done that except I'm usually so p***** off with myself it goes straight in the bin

[mobjack68]

The "snap" is usually followed by...Oooohhhh S**T....and the adrenal gland signals you to DUCK....and quickly. When the subconscious gives up and reality comes into focus the next action is to try to get to the OFF switch. Mine is close to the floor so I can crawl in safety to turn off the wobbling lathe. Good to know you only lost the lip off of your blank. Good friend of mine "exploded" a rather large piece of something. BROKE the turning tool (the metal part) and knocked him out cold. 3 stitches to his chin and scratches on his noggin. We cleaned up that mess for almot 4 hours while his wife, once again, escorted him the the emergency room. Sorry for inconvenience and that's usually the way I discover my limitations.....keep turning!!

Well Joe you now truly belong to th ranks of the "Midnight Gamblers".:D:D

That's 'cos you haven't done it properly. If the lathe's dancing about the floor in an unbalanced state, you've only converted half the material into a UFO. When correctly done, there are only three questions you ask:

1. "What was that?" as you hear a buzz past the ear.
2. "Hey, where did my wood go?" as you go to take another cut and meet no resistance.
3. "Am I bleeding?" as you pat yourself down.

And sometimes there's a fourth, asked when you start prising the UFOs from their landing sites in the ceiling, cat, etc. "And I do this for fun?" :rolleyes:

[Chipman]

You ar right Skew.... if it lets go, you don't get time to duck if it is going to hit you.... just "tomato sauce" on your hands when you rub where it hit.

If you are lucky, it just goes at a million miles an hour across the floor.

One thing I discovered this afternoon. NEVER SWEEP THE FLOOR.... why you might ask:? Well it makes a great way to save your bowl if it flies out of a jamb chuck:oo:. I think it must be time to invest in "cole jaws"



Wear your face sheild... getting hit in the head is just not worth it!:D

Skew..man that is funny!! I try to do most things "properly", and yes, I have been on the receiving end of total destruction...makes you kinda wanna just sit for a minute and remember to breathe.....
