View Full Version : Mango - is this normal?

G'day - I managed to pick up a few pieces of Mango on a recent trip to the coast and have finally got round to having a go at it.

Started roughing the outside of this 19" piece, to find what appears to be some dark heartwood.
Does mango have contrasting heartwood/sapwood (not from what I've seen before) or is this purely as a result of the spalting?
Was pleasantly surprised to find this as I had expected it to be rather plain.

The pictures/lighting doesn't really do it credit - looks much better in the real.

Look forward to finishing it and getting some oil on it.

Aside from knowing nothing (nada, zero, blank) about mango, I'd expect heartwood of any species to have more even boundaries. Also, the pattern doesn't seem consistent with my perceived centre of the log. More likely spalting.

Pictures look pretty good by themselves. I guess I had an optical delusion with the foot; first thought it had a big gap in the ring on one side - the crosswise streak is curious.

Hmm seen a fair bit of mango, must be africa...dunno:? But it looks darn good heart wood or whatever. Most defintetly post the finished pics


But Cliff is the best for the final verdict, I will defer to his knowledge and experience.

Great piece Andy. A real find.

Only bit of mango I had was affected by a dark fungal stain and looked crappy.

Andy, that's comin' toward a beautiful turning! Scored some awesome timber, there. Don't know anything about Mango, either, but I'd think it's the spalting rather than heartwood.
With Hughie on this'n... I'd like to see the finished piece.

I've seen some mango with varying colours, but not like that. The only spalting that goes on in the mango I've used is just blue mould all over - yuk :((

Looks like a darn nice piece Caveman

I agree. :2tsup:

And again. :2tsup:

I have messed around with a lot of mango & I hate the blotchy mould that it gets if you don't treat it the right way.
I wash it heaps to get rid of the sap, then rough turn it & wash it again.
I have also messed around with microwave & freezing.
The trick is to dry it as quickly as possible without letting dust or mould spores settle on it

That is a very nice piece, I'd be very happy if anything I had developed mould that looked like that.
You can see that it isn't heartwood colour 'cos it doesn't follow the grain.

I'm wondering if maybe it was caused by damage to the tree while it was still alive 'cos I haven't seen anything like that develope in the stuff I have collected from healthy trees. :think:

I have seen these patterns in mango, and other species, before. It is caused by a fungal attack, which is the beginning of a breaking down process and usually stops as the timber dries out.

Caveman,

I'd say spaulting. I've turned some pretty speccic pieces in darwin, see attached. These were from some logs left out for a few NT wet seasons.

Nice piece Pete, maybe I should try getting a log & leaving it in the rain forest for a while. :think:

Just from our recent advanture, i can tell you that mango can have some quite hard bits in the middle when it gets some size.

The stuff we cut is still vey green so who knows what colout the hard bits will be.


cheers

Nice piece Pete, maybe I should try getting a log & leaving it in the rain forest for a while. :think:I reckon you'll just end up with an overly rotten chunk of blue mouldy wood :shrug: Will wait anxiously for the results of your experiment Cliff :U (now that you've committed yourself!) :;

PS: pretty spekky bits of wood Pete and Caveman - too nice to be Mango though :C

Thanks for the comments guy's.

Finished and oiled the platter with BLO. Will buff it at some stage once the oil has dried fully.
The oil kind of evens out the lighter/darker wood not leaving so much contrast - still nice tho.
My largest finished piece to date (in terms of diameter anyway).

Have some much larger lumps in the woodstore, but need a bigger lathe to take care of them!

Came up well Andy. Lovely piece.

So now you're hanging out for the Stubby ...

Looks really superb, Caveman. Isn't it an absolute joy after all the cutting and sanding to put the finish on and be presented with that grain!:2tsup: Great job!

Hmmm, If thats mango............my neighbour better watch out :U :U


That has turned to be something rather special, well done! :2tsup:


Look forward to the rest when they are done.

Skew ChiDAMN!!

The problem with a piece like that is that all the descriptions that pop to mind are either hyperbole or will sound like I'm preparing to ask a BIG favour.

Except, perhaps, to say that if I had turned that, for the next week SWMBO would be making pointed remarks about swollen heads. :rolleyes:

Excellent bowl, like the simple lines that allow the timber to be shown to its full effect. Nicely turned and well finished, congratulations.

Thanks guy's for all the compliments. Sure was fun to make.

Yup - can't wait - looks like they're gotta to make the boat to ship it out here with too - waiting, waiting - getting really itchy fingers.
I quess it's worth the wait though.

A bit of finish and it becomes something else altogether :o! Extraordinary bit of wood Caveman - beautiful :2tsup::U

Do I gather you're joining the Stubby ranks then??:;

Thanks Vern - yep, placed an order a month or so back - it's mostly built and put together now - looks like they are waiting for the right tide to ship it though!
Seriously looking forward to having something big and solid that should be able to handle anything I can put on it.

My +-20year old record lathe has put up with a lot and has amazingly come through pretty much unscathed, though I can feel the bearings are at the end of their tether. I have some large lumps of wood sitting around that I can't put on the record coronet as they are too large and too heavy and I would hate to have to trim them to size to fit - wouldn't be doing justice to the lovely tree they came from.

That piece of mango is about the limit in terms of diameter of what I can do now.
