Green Oak Burr

[Random Orbital Bob]

Last of todays questions for you turners out there.

Today I had a bit of luck and chainsaw'd a few oak burrs from a downed friends ancient oak tree. I've never had to store burr'd oak before and given its premium value for turning....dont want to cock it up!

Is there any special consideration one should give to oak burr to prevent shakes, cracks etc. Naturally I want to keep of much in turn-able condition as possible. I literally saw'd it off the down'd stumps this very morning...bark n all.

Many thanks

Haven't been lucky enough to get hold of any decent burrs Bob but would think that if you leave the bark on the outside and seal the cut face with endseal/pva/gloss (not emulsion) paint, then leave in a cool place under cover, you should have the best chance of keeping it usable.

Cheers, Paul

I'll bring a piece up for you on Sunday Paul

Might be able to find something to swap Bob, bit overrun with some new supplies at the moment courtesy of a friendly neighbour

Cheers, Paul

If it a good tight burr it's is great to turn straight away. You can get a wonderful leathery texture on the finished piece with the way the burr dries.

I've found with burrs they dry pretty good with few shakes and cracks because of the conflicting stresses and tensions in the grain from the formation of the burr. However it does depend on how tight and dense the burr is together with how much straight grain is present.

I was rather hoping someone might say that. I had thought along similar lines ie the complex grain direction would alter the tension "certainty". I've turned two bowls so far and it turns very nicely green (as you'd expect). It will be interesting to see how they move/twist.

Its lovely stuff though...check this out...not complicated and not all burr as this piece was right at the edge of the burr'd bit. Another pic shows one that just missed my head as it flew off the lathe!!!

Stunning in more ways than one !!

mmm burr's are delightful but not so much when airborn!

Thanks folks....yes, perhaps a new olympic sport.....speed bowl turning while being bombarded with broken fragments!

A quick post script to this....Paulm very kindly invited me to test out hollowing tools as he lives close to me. I just wanted to publicly thank him for his kindness...also the inspiration I derived from such a marvellous workshop and a man clearly dedicated to his craft. Thanks again Paul, it was a pleasure meeting you.

 

[paulm]

You're welcome Bob

Hope it helped with deciding on your eventual choice of hollowing weapons :lol:

Welcome any time.

Cheers, Paul

 

[Random Orbital Bob]

Its certainly helped focus the right search now...also apparently I'm now going to be searching for a chainsaw milling attachment

 

[paulm]

Have a look here, it's where I got mine from http://www.alaskanmill.co.uk/ Lots of vids on utube too, you know you need one :lol:

Cheers, Paul

Brilliant Paul....gotta get one
