When you've used up all the turnable wood in the shed and the chainsaw needs a new chain you resort to this...https://uploads.tapatalk-cdn.com/20190330/e486f045a1f34dd935e94ba6b002ba28.jpg

After you have made it round, 2 or 3 wraps of masking or other tape around the edge will give some peace of mind. Leave it on and just slice it off when finishing the upper outside and rim. This may be overly cautious, but I would rather that than bowl halves flying around the shed.

Once it’s painted no will know that it was Radiata!!
Just kidding! :U

PS aren’t most modern wood glues stronger than the wood they glue?

Well, funny thing happened...

Turning away, glue holding just nicely, outside finished with a couple of coats of shellawax, looking quite attractive I think with all those tiger stripes. Turn it over into the chuck, hmm, just a little bit of a wobble, check the mounting, looks good, it's only a tiny bit of a shimmy, these things happen, I'll just flatten it off and keep going...

Hollowing out, going well, got the lip shaped up, roughing it out is going well. Hey, I might be getting the hang of this stuff! There's a bit of vibration but nothing out of the ordinary for my old lathe.

That shimmy turns into a shake and the wood really isn't happy. Stop for a look and you can see what I'm getting in my cut, rough as the proverbial. That's not good. Check the mounting, it feels the tiniest bit loose so I tighten it up but no, it still feels a bit off. Time to take it off for a closer look.

Have a close look at the third image, the eagle eyed among you will spot the problem.

Ohhh, well, better luck next time. https://uploads.tapatalk-cdn.com/20190331/e43bf15e40ef1b1c06af0d606f54787a.jpghttps://uploads.tapatalk-cdn.com/20190331/b35df4435dbe8b443c0e3cd24f64e701.jpghttps://uploads.tapatalk-cdn.com/20190331/f823fdcf0784640513551ddf72b610b8.jpg

I was never really worried about the glue holding, just my projects have been problematic of late. Obviously with the softer woods I should use a bigger chuck to spread the load a bit, stop compressing the fibres so much. The little two inch jobbie has served me well up until now but in much harder words.

Time for an upgrade I think.

Skew ChiDAMN!!

The compression shouldn't cause too much problem, although it's certainly not desirable... to me it looks like the spigot is actually a shade too large a radius, so it is the ends of the jaws that are compressing.

But, possibly of more concern... are those cracks in the spigot I see in the 3rd pic? You certainly do NOT want the spigot to sheer away from the blank... :no:

Yeah, that crack is the main problem I think, and the reason the piece is now sitting on the bench at home. Sometime this week I'm planning to put a chisel into that little crack and see how far it goes.

I'll put the piece between centres on the weekend, perhaps a bit of judicious trimming might let me get something out of it. I'm certainly not going to stand right in front of it though.

Have you thought of cutting the spigot off and gluing on a hardwood block instead? That is if you really want to try and rescue it?
