might have a job of 50 or so 2 1/2-3" spheres to make and my big home built sucker for my 5" skittle balls is just too big and the cutters won't reach.
what is the best one out there and is this one by vermec any good???

That Vermec Jig looks pretty solid, I like the pedestal design. There are a couple of points worth mentioning thought. The cutter shaft is rather slim and due to the short adjuster you can’t get the cutter very near the post for maximum support. The cutter is 8mm dia and having used a flat 9mm and cupped 6mm in my sphere jig I think they would have been better served by using a 6mm. There is no handle for swinging the cutter round. Rather expensive.
Not tried the type but there’s this one on the auction site.

I have a ball turning jog for sale fits a 30mm banjo. photo attached £30 plus postage which I estimate about £10.
Cheers Martin.
-
The handle on that is filthy Martin! ;D
-
just how well do those things off Ebay work then?????
to my eyes they are rubbish but then i've never used one.
do they actually work well?
Martin i have a 1" post so can't use that one thanks.
-
I bought it for a commission and it did the job well as with all of these jogs small cuts is the way to go. I added the price of the jog into my quote so winner winner chicken dinner.
ps It took ages to add the dust to prove I had used it.
Cheers Martin.

I use mine a lot when doing resin hybrid spheres, rough out by eye then finish with the jig - wouldnt be without it - fast and repeatable.
-
whom's is it???
-
This is my home made one. I just made it up as I went along from materials I had to hand. If it was money no object it may have been a bit different.

think i'll plump for that one then as i can always resell it once the job is done.
easy to use is it?

There are a couple of jigs on the market, one made here in the UK and one made in America that are very similar. They’re both made of Aluminium Alloy and don’t look to be very rigid. You almost always see them turning relatively soft woods and between centres in the videos. With a more substantial jig you should be able to turn virtually any timber just held by the chuck giving you access around more of the workpiece and without the tailstock getting in the way. Although my own jig has a steel base and column I don’t claim it to be any better but I do turn spheres with it without tailstock support. Admittedly this is lime as in the video but you get the idea. I’ve turned Oak, Ash, Maple and Yew like this.
-
Just to add, although I made some observations of it, the Vermec jig linked in the OP looks far more solid made almost entirely of steel by the look of it.
-
it looks a cracker i'm just not sure i want to pay 400 AU dollars and delivery for something that i'll eventually sell and not get most of my money back for.
might think about keeping it though.
-
If you have a lathe with a modest centre height one of those jigs with the tall, relatively thin posts may be fine, on larger lathes though I’m not convinced by the design. I hasten to add though that the only jig I’ve used is mine and I’m happy with the design given it was made with what I had to hand. Some jigs though can be quite expensive, a German one I saw was over €600 and looked a bit fussy in design. Given the low cost I might be tempted by the eBay version. My problem is I like making tools!
-
i want the tool to have resale value if i decide to sell it. not confident on that ebay one. there must be a reason as to why no one raves about the design???
my lathe is a Jet 3520B and if Lazarus can use one of his VB then it should be fine on mine.
i'd use mine i made if only it would do balls that small.
you can see mine in operation here.

Can’t you just make a new cutter that will enable you to make smaller spheres? Your home made one looks pretty solid, I can’t help thinking you’d be disappointed in the commercial one you’re thinking of. If you do buy one though and find it works well it may be worth a quick review as it may help others. ;)

I have seen this method shown at a demonstration and also a sharpened scaffold tube also used the latter just being hand held.

i can not get hold of more of the steel to replace my cutter that easily.
the replacement i did find was not good enough.
i'll do a review of it if i do end up buying the gadget...

The eBay one works in the same way as this one. Although the one in this video is more sophisticated the principle remains albeit cutting metal in this case.
