Thread: Newbie - Just got a Nova OT

wow! i want one NOW! looks cool, is it a whole machine by itself or in the pics in looks like its attaches to a standard lathe ?

looks like it would be easier than finding or building a rose engine..

Check out the website John.

It's an attachment .... some limitations on what it'll attach to though.

I'd love to have one, but that'll probably never happen.

Which is why I'm building my own rose engine. At the current rate of progress, I reckon I'll have it finished in time to start decorating my coffin...

(Maybe I should look at investing my pennies in this Teknatool toy instead. )

The 'darksiders' talk about a coffin smoother; make your own analogy ;-}

yes i checked the manual

http://www.teknatool.com/products/Sp...tal_manual.pdf

very funky piece of kit, its handles the M30 thread for Oz, very kind of them..looks like it's kinda designed to fit a Nova3000 lathe (funny that)

This version is designed to be used with our Nova 3000 Woodlathe. It is not designed to fit,
nor should it be used on any other lathe type or brand.

ho hum...

Can't remember where I read it in the welter of guff John, but they did say the screw-on cutter was only available in one and a quarter by 8. Perhaps this is only for the US market; don't know.

Funky it sure is. Not my cuppa char tho.

1.25x8 seems to be more or less standard for their chucks, as that'd be the largest needed. They have adapter inserts to fit almost all smaller headstocks. Unfortunately, they have no adapters going the other way, which is what you'd need to mount existing chucks on the contraption. Can't much blame them for peddling their chucks, I guess.

No reason I can think of that would prevent a machinist making a reverse adapter: 1.25x8 inside, your thread outside. For most, this would be a longish necked-down affair; although it'd increase the cantilever to your chuck itself, side loading probably isn't severe enough for concern, as long as feed rate is kept low.

the manual says its supports M30, i guess when they ship specific units down this way..

SPECIFICATIONS
Spindle Thread: M30 x 3.5 pitch RH (Australia, NZ, Europe))
1 1/4" 8TPI RH (USA, Canada)
Spindle Height Above Bed: 200mm
Index Plate: 24, 72, 96 Divisions
Cross Slide Travel: 165mm
Top Slide Travel: 165mm
Circular Cutting Frame Diameters: 0 - 55mm

I checked the Teknatool lathes on Crarrols supplies and is says they only come with the 1 1/4 8TPI but like Joe says an adapter should not be hard to come by..

the FAQ on the site says that both OT use on alternate lathes and various spindle threads are supported

Australia and America have different spindle threads on the Technatool lathes I think.

Metric in Oz, Imperial in US.

that is correct for the older lathes but because of pressure from the yanks all the new lathes come with the 1 1/4" x 8tpi thread.

It was one way for the kiwis to cut production costs by having only one thread spindle to make.

Jim, does that mean I would need to run the Teknatool chucks or get an adapter if I wanted to run my M30 insert chucks like the Vicmarc ones or get a 1 1/4 insert for my other chucks or change inserts if I wanted to change to sawp chucked work form one lathe to another ?

Am planning to buy a mid sized lathe later in the year and cos of the OT attachment have just changed my mind from a Vicmarc to a Nova DVR 3000...tho it may change again before purchase ;-)

Thanks Jim.

It seems Wivamac also has an OT atachment similar to the Teknatool one http://www.toolpost.co.uk/pages/Wiva...l_turning.html looks pretty solid but may be more expensive than the NOva one..

I been reading this through. Reading about the different threads. So does this mean the thread on the nova will be different to that of the ornamental turner? Jim do you need to buy attachments or should it fit onto the nova 16-24

thanks Toni
