I received a Vermec Sphere Jig for my recent birthday. I have turned spheres by hand from 50mm to 150mm diameter in the past and the jig interest me.

I totally bodged the first attempt, I did not have the jam chucks sorted and produced a lemon. No there is no pic, it is almost as ugly as my mug, so in the interest of public safety . . . :;

I got the jam chucks sorted and revisited Guilio and Brendan's vids on the jig, saw where I had made errors and corrected my technique.430758 My second effort, NSW Rosewood, 80mm diameter

Today, I challenged myself to turn a Spherical Turned box. I had this offcut of Red Ash (I think) about the dimensions I wanted to play with, 73mm diameter.430750

I turned how Brendan did and still had some minor issues, but was able to correct them. Tool control to reduce spigots 50+mm over the tool rest is interesting. I got the magic spiral :;430751

Luckily, there was enough meat to remove that and still end up with sphere.430752

I removed the majority of the spigot with a hand saw, then a 12mm skew in scraping mode. 430753

Of course the bottom cracked when some ham fisted oaf rechucked it.:doh: 430754

But I managed to save it . . . 430755 430756 430757


I am happy with the jig.

Why are the vids we watch always make the activity look so easy to duplicate????. Pat your perseverance was worth while, it looks good from here. I have thought of making the apparatus but that is as far as I have got....thought. Its still a bit hot to do anything in the shed even with evaporative cooling.

Rod, as a tool maker, I am good at turning mallets. Anything more complex, then I'll pay for someone's expertise.

I s'pect it would be very easy to start out with something the size of a bowling ball and end up with a marble. :doh: Glad I'm not a turner!

The box is very attractive. Nice work. :2tsup:

They do not show the balls that look like misshaped goose eggs, or video the ball sailing majestically into the neither regions of the shed after a massive catch.

It reminds me of that old story about a brother who wanted to make something for another brother's birthday. When unwrapping the parcel a tooth pick was the gift. Then the brother admitted...."Well, I started off making a coffee table but I ran into a bit of trouble then I started to make....well in the end the only material I had left was enough to make this tooth pick"

I think we have all been there if we are honest

Very nice Pat. The rosewood one looks particularly good.
For inspiration, check out Frank Howarths videos on the 8 ball and the death star.

David Springett is also worth a look for the aspiring sphere turner:U https://www.youtube.com/results?search_query=david+springett+woodturning+wizardry

Latest in the saga, some ham fisted yokel managed to have a "significant" catch.

Let's just say, after hollowing out with a bowl gouge, I set up the jig to make the final cuts and the stuff up fairy caught up with me.431263

A very late in the day email to Vermec and thanks to Nadine and Enzo for supplying a solution. Off to the post office tomorrow morning.

Lesson learnt, Sydney Blue Gum requires very gentle cuts, you great big yokel!

Enzo thinks he can fix it and I'll go with his judgement.

I can fix a lot of issues with tooling and machinery, but this is a little out of my league.
