    Hi Acacia2
    If that is Hardekool, ( Leadwood, Combretum Imberbe), it doesn't finish very well. It has a dull flat finish. However if you get C. Apiculatum , Rooibos then the finish comes up beautifully. Have a look at the two woods in the book Properties and uses of Southern African Woods.

    I have found that when you turn the hardwoods such as Hardekool, African Blackwood etc then you need to grind your chisel in the region of 60/70 degrees, ie almost scraping . And have the grindstone next to the lathe as you will need to touch up constantly.

    will do. One of the problems is that the locals use the same name for both trees. Umbondwe-omnyama. The bark is different and the flowers as well. Apiculatum is a smaller tree, I have got my pieces of C Apiculatum from firewood / braai piles in Swaziland. Its hard and turns well.
    haven't been up to the Lebombo Mts for a number of years, We were Honorary Officers at Tembe for a number of years , but fortunately they Hluhluwe/Sordwana /KoziBay road was finished so didn't have to do the trek over the Lebombo Mtns at Jozini

    Here are a couple of pages from the book "Guide to Properties and Uses of Southern African Wood" It is a book well worthwhile getting hold of as it covers some 150 local timbers.

    Look at the bark, the bark is shown on the edge of the pages I copied, and there is a marked difference between the two species, and smaller leaves
    I have also found the Apic is "redder" in the lots I have got. Are you up at the Hospital there (Bethesda)?

    220 grit the FINEST??? at work we sand down seal coats with 320 as standard these are available at most hardwares as a disk as well as finer' 2000 grit and finer you might have to find a supplier to car finishers and I have heard of 4000 grit for getting scratches out of things like aircraft windows. By the way keep 60 grit far away from it -might as well use railway ballast - would take you forever to get THOSE scratches out.

    Ebony isn't an easy timber to turn unless you have good turning skills. Those groves could be sanded out in a soft timber but not in ebony. However with good turning technique they wouldn't be there in softwood or ebony, so shouldn't need to be sanded out.

    I'm sure others will agree and may give you some tips. The best tip I can give you to fix the problem is to get some lessons from a skilled turner. Maybe have a look on line and see if you can pick up some insight into turning goblets with clean smooth cuts.

    Doesn't help with what you have right now unless you can re chuck and turn the inside again but might be of help for future goblets and other hollow objects.

    Cheers - Neil
    Good advice and I agree. Once you get things sorted you will find these rings will be a rarity. Ebony will develop sanding cracks if your too aggressive much like most really pieces of hardwood.
