I recently bought the NOVA SuperNOVA2 23055 chuck. But it does fit my lathe, the thread on my lathe is m33. And that is why I am looking for an adaptor. Does anyone know where to buy one?
Thanks for you help!

I don’t believe Nova makes an insert/adapter for the 33mm.
You would have to buy a spindle adapter and then the appropriate Nova insert.
The 30mm seems to be the largest.

You would need a spindle adapter like this and then the insert for the chuck to fit the adapter.

Paul you bought the wrong chuck, you do need the Supernova 2 chuck 23062.
That one is direct threaded for 33X3.5mm

The only place that makes an adapter that you can use is Best Wood Tools, they have 33mm X 3.5mm to a couple of other sizes, here is the link.

Ik weet niet welke draad je nu in jouw hebt, dat zul je dus zelf uit moeten zoeken, zoals bv AD-402 is voor 33mm naar 1”X 8tpi.

The PennState in my post is 33mm to 1X8” for $20 rather $70 at bestwood tools.
That said, if you can swap the chuck for the one Leo mentioned you will not need a spindle adapter or chuck insert.

I would not recommend pen state adapters, even if they are much cheaper, just not what I would buy myself either.

Leo and Lee, thanks a lot for your answers. Bestwoodtools looks promising and I will contact them.

@Leo: leuk je hier ook aan te treffen. Ik kan je bijdragen aan het Nederlandse forum altijd erg waarderen. Zal eens kijken hoe ik achter de draad van de chuck kan komen. Op de verpakking en manual staat er niets over.

The Supernova 23055 female fitting is 1-1/2×8TPI UNC so according to this I need the AD-404 adapter.

That may work Paul but I suspect not.
With Nova insert style chucks the transfer of power is from the end of the insert to the interior body of the chuck and from the headstock to the hex section of the insert.
Your new spindle adapter may thread into the chuck but it also must mate exactly with the interior of the chuck. I think it would be very unlikely that the spindle will allow the mating of the chuck against the headstock and against the interior.

Maybe where you are 1.5” spindles are common but most newer ones here are either 1X8 or 1.25X8. By changing your spindle to 1.5X8 you must also have available (if you need) other chucks, faceplates, and attachments.
Whether you go with the less or more expensive spindle adapter you may consider going to a 1.25 rather than 1.5”. Of course, if you go with a 1.25 you will also need the Nova insert for your chuck.

Lee I assume ( I know never assume) that the OP is referring to the internal thread in the chuck.

As for common thread spindles, anything other than the 33mm is Not common, that would be the reason he is looking for the adaptor probably.

Some new turners do buy stuff out of England and not knowing get stuck with inch sizes, especially when buying used equipment from there, as pretty well al new and even imported from the far east has the 33mm size spindles.

I grew up in the Netherlands, and in that time both metric and inch sizes where being used, especially in the metal industry, I have thus learned both and I can readily go from one to the other,

Though now it is all metric, and overall it is a much easier system to use IMO.

Lee and Leo, thanks a lot for your advice and comments. I contacted the supplier of the chuck and I can return it.
I guess this is the best solution after all.
