I just ordered a dvr xp from woodcraft and it comes with this
http://www.woodcraft.com/Assets/Rebates/TeknatoolSN2ChuckMIR-Feb2016.pdf

I currently have a nova comet II lathe and I have a barracuda II chuck system and a nova G3 chuck for it. my question is, can I use those 2 chucks on my dvr xp if I get this
http://www.amazon.com/gp/product/B000KIADBS?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00&tag=vglnkc7237-20

If not can I use the G3 chuck at all with the dvr xp? If so do I need to get the ILNS 1 1/4×8 nova threaded insert?

What would I need to use my barracuda II chuck system with my dvr xp?

I have been searching for hours for the answers but no dice so I would really appreciate if anyone can give me answers that knows for sure! I want to be able to start turning with it as soon as the dvr xp gets here!
Thanks
Chris

I would get the Nova threaded insert for the G3. The reason being that the DVR can run in reverse and you want any chuck you use in reverse to have the locking screw on it to prevent the chuck from coming off in reverse. The adapter will work with the barracuda II as well as the G3 but for reasons mentioned above I’d be very careful that I didn’t run it in reverse while using that adapter. Congrats on the DVR. You will love it.

I am not familiar with the PSI chuck but your link should work.

You have the correct insert listed for your G3. IF, IF your G3 is the insert type. Nova also makes a direct threaded G3 which an insert will not work with (such as the G3-D Delta, and the G3-Comet). If direct threaded you may be able to use the PSI adapter. If you get a “Nova” insert get a real one, not a knockoff sold by Woodcraft …I had one, almost 4X the amount of runout it is so poorly made. A real Nova will come in a red Teknatool box. The insert they show in the picture is a real oem Nova.

You can use your existing chucks if you go with the PSI spindle adaptor … just be advised that the PSI adaptor does not have set screws, so it is unsafe to run your lathe in reverse with it in place.

I have the adaptor you linked to, and mine runs pretty true, but I have heard/read that other users experience some pretty bad run-out with spindle adaptors.

Chris,if you know anyone who is a machinist, take your G3 to them and ask to have the threads increased to the size of your new lathe spindle. It’s a piece of cake to do for a machinist. And a beer or two should get it done without paying regular machine shop rates.

Also, if you look closely at the ILNS inset by Teknatool, you can see thread remnants near the inside opening. If you can remove those remnants, the insert will screw onto your spindle much easier. A .010” cut should be all that is required to remove the remnants, and you’ll be a lot happier.

Another tidbit, when locating a point on the spindle for the set screw to screw onto, with several inserts, none are going to sit at the same place as the next one. If your spindle is designed to accept the set screw, no problem. If your spindle is threaded all the way, then the set screw can damage the threads that will eventually cause the inset to gall either the spindle or insert, not allowing it to be removed when needed.

What I did to solve that issue was to screw in one insert, set the set screw until it bottomed on the spindle, then backed it off. I made a mark on the spindle where the set screw marked it, and proceeded to file a flat on the spindle. After that was done, I got another insert, and screwed it on until it bottomed out. Of course, the set screw didn’t line up with the flat, so I marked the insert with the mark I made on the spindle. I then used my drill press to drill a #3 hole in the insert, and tapped it to 1/4-28 because I have a lot of that size set screw. I have another insert that I’ll do the same to when I get another chuck. Unless you have metric drill bits and taps, toss the metric set screws and go with the fractions.

I have a G3D chuck that if I sell my older lathe without selling the chuck, I’ll direct thread it to 1 1/4-8 to fit the Powermatic spindle. ............ Jerry (in Tucson)

cdaniels: I sold my Rikon and bought a DVR XP – wonderful machine! I had some older threaded 1×8 Nova chucks that went with the Rikon, except for one midi-chuck. I bought a 1-1×4 to 1×8 adapter from PSI so I could use the midi-chuck, tapped for a set screw so it would run in reverse, which I use it as a “permanent” fixture for the cole jaws. The PSI adapter is heavy duty, so there is no problem with run-out.

FYI: When you swivel the head on the XP make sure you realign it by inserting the dead enter in the headstock and the live center in the tail stock, slide the tail stock up so the centers are almost touching, then “nudge” the head so they are in-line and tighten the head down.

thanks for all the help guys, I got the 1 1/4 nova insert for my g3 and I got the one that comes with 2 extra grub screws but the extras are bevel head and not a normal set screw so wtf???it turns out the g3 is a G3 comet II chuck which was made specifically for that lathe and doesn’t take the normal insert. I’m going to do what nubs and stubs said and get the G3 direct threaded to fit my dvr xp spindle which gets here tomorrow!!!.
I also got the PSI adapter which my g3 fits onto as well as my barracuda 2 so i’m ok with that except now I need to drill and tap a hole in the adapter for a set screw so I can use all the chucks in reverse while using the adapter. I should be able to do that myself, I have a tap and die set for metric and one for standard. I think i’m going to tap it to the same size as the set screw the nova chuck takes to make it easier to have replacement parts on hand.
i’m building a new tool cabinet for my tools and chucks now so i’ll post before and after pics once it’s all said and done. thanks again

Sounds like you have things under control … happy turning!

Here’s what I did for a tool cabinet:
