Nova G3 adapter (Nova PN 'ISNS')

bobgroh · Post by **bobgroh** » Mon Dec 31, 2012 12:52 am

Going to upgrade to the new PowerPro head and would like to upgrade my Nova G3 lathe chuck adapter from the originally supplied 'IFNS' part to the new adapter 'ISNS' (which apparently has a longer hub and a bigger setscrew).

But I kind of have a 'good news - bad news' situation. The good news - the new part is available (from SS) - the bad news is that the price is a bit steep (almost 3x the price of a regular Nova adapter). Ouch.

Now I like to support SS and I like to buy from them and have done so to the tune of over $2K this year alone (PowerPro update plus lots of miscellaneous parts). But this is a bit much - at least for this retired guy. Does anybody know of any other place that has these adapters?? I've tried all the one's I could find but no joy so far.

I am probably being unreasonable and a bit petty here. SS probably had to have these custom made for them and the price is probably high as a result. But right now ..... well, I'm a bit miffed.

I think Teknatool was selling replacement adapters for around $20.
The ISNS adapter was specially to allow a 5/32" set screw to sit flat
on then angle of the shopsmith spindle.

I believe if you do a search around Arpil, there is a long threat on the adapter and what people did to get the ISNS. Teknatool came out with a letter and to my knowledge sent people the ISNS adapter instead of the IFNS that was included by mistake with the adapter included in the kit.

I bought my Nova G3 from Shopsmith but I don;t know exactly how much I paid. I think it was in the vicinity of $150.00. Mine came from Shopsmith with the adapter that caused so much excitement here on the forum. In fact, I contributed to that "discussion".

I contacted Teknatool and their CS gentleman told me there had been some sort of mix up in marking and then he sent me an "appropriate adapter".

The big difference is the set screw that secures the adapter to the headstock shaft. It is set at an angle to match the taper on the Mark V shaft and uses the standard Shopsmith allen wrench.

NO BIG DEAL. If you have the "wrong" adapter, you have to use a different allen wrench. Yes, the set screw meets with the drive shaft at a different angle but does that cause any real issue. I don't think so

In a machine shop - maybe. On a wood lathe, I have serious doubts.

If you get a good deal on the Nova G3, my recommendation would be go for and when it comes check to see what you got. Be careful though. There are a lot of different "packages" out there all called the Nova G3. The contents do vary (along with the price).

$300 - no way! Ypu can get two for that.

You might want to contact Teknatool. They sell reconditioned units.

Bob, what was the Shopsmith price on that adapter? They're about $20.00 at Woodcraft and other places.

Another reminder, I have a G3 from shopsmith (from some years back) that has the same # adapter as the "bad" one but it has the correct set screw and the correct angle. So you need to look at the size allen head in the set screw and then check to see if the set screw is at an angle (mind you it is only a couple of degrees off). You should not assume just because you have the old number that it is wrong.

Can you really purchase a "Shopsmith" adapter at Woodcraft?.

then search for Nova

The one sold by Woodcraft is the "F" version and costs $22.99. All the others are $19.99. See: http://www.woodcraft.com/product/200519 ... nsert.aspx --

This "F" version looks different than mine in that the hex section is wider. Perhaps that's to accommodate the Shopsmith set screw drilled at an angle.

Thank's for the conversation - here are a few more 'factoids' to thrown into the mix.

#1: I already have my G3 and have been using it happily for over a year now. Happy as a clam and the Nova adapter (PN IFNS) works fine. So far.

#2: Shopsmith wants $51 for the new adapter (PN ISNS). The rational part of my brain says this is not unreasonable - it is undoubtedly a special part and probably there is tooling charges, etc. But the SS customer me (you know, the guy who loves his SS, rooted for the company during it's troubles and who spend a bunch of money over the last couple of years) is just a bit miffed that my loyalty is not matched by their loyalty.

#3: The changes to the adapter are more than just the setscrew size and angle - the height of the 'head' of the adapter (the part you see after the adapter is threaded into the body of the chuck) was increased - probably to accommodate the larger setscrew and angle it to give it a bit more bite. The need for the change is probably because of the increased torque of the PowerPro setup and the 'pulsating' nature of that torque.

I do have a new PowerPro head and I would like the increased margin of the new adapter. And reality says I will probably have to eat the extra cost. But the customer me is still not happy (that factoid and $3 will get a coffee someplace!!)

Where do you find this factoid? Are you certain that this is the price for just the adapter?

The answer is 'Yes'. I did get a reply from Shopsmith customer support with the Shopsmith part number (FYI - the Shopsmith pn is 522470) along with the price. As I said, a bit steep but probably (#1) not unreasonable and (#2) probably the best I can do.

Bummer.
