There is a lot of info on the G0602 on the ProjectsInMetal(dot)com forum. I don't have the specifics myself, but perhaps Jim will see your comment and reply. On his G0602 he used a DC motor, but he said would use a VFD if he had it to do over. Several people have talked about their VFD conversions on the forum.
I was thinking about changing out the gutless AC motor on my old lathe with a 2HP DC motor I salvaged off a treadmill also. After seeing it in action it is on my to do list for sure now. Great mods on your lathe all the way around!
would love to see how you made the reverse feed what gear? and how it is all done i can make what i need other than the gear, what gear are you using to do this? a complete video on how to do this tell me where to find this if you have already done so thanks Eddie
My G9972z doesn't have power cross-feed but my G4003 does have it, as well as reverse-feed for threading left-hand. Not always a good idea to reverse and cut heavy with screw-on chucks of the smaller machines. Some chuck bores on these are smaller than spindle bore. For example, the 3-jaw on my G9972Z had to be opened up with a boring bar to get closer to spindle bore size. I'm using treadmill motors to re-power some tools. Adding a jackshaft, a HFT metal blade, and DC motor to my 14" 'wood-cutting' bandsaw was a cheap conversion for cutting metal too. Speed control is via HFT router speed controller and a 50a-200PIV diode bridge rectifier to convert AC to DC. Cinci #2 T&C grinder sports similar motor conversion (vs OEM 440v 3-Ph), and I just plug in the one speed control to run each DC machine in turn. Motor torque is reduced even with the speed control's PWM method, but slight variations below WFO are often enough to just reduce chatter. G9972Z is next to be converted to variable. :-) btw, G0619 has 3-PH spindle motor and incorporated VFD. When is sits for a long spell, it's important to run for a while at low speed with no load to reform capacitors within the variable drive's electronics. I run a short version of 'break-in' procedure to do that.
Hi I would like to know since this lathe does not have auto cross feed...are you happy with it being this way or do you miss the auto cross power feed??? I have the itch to buy a 11x26 hopefully I dont miss the ten inches from 12x36 I am used to but that cross power feed keeps stopping me. I think the price is pretty good but cannot make up my mind. Can you please let me know what you think. Thanks Manny
I myself don't think reverse tumbler is "rarely used" For 1 thing: handy for threading AWAY from the Chuck 2. Boring from left to right, away from chuck. Both operations come in pretty handy.
As far as I know, you can thread away from the chuck by just running the chuck in reverse but you need to put the tool upside down on the far side of the chuck.
I'm missing the part of the reverse idler gear. Is that big lower gear movable? It is in different spots in the video. I do not own one of these yet, so excuse my question if it dumb.
The large gear on the bare metal swing arm with the curved slot and lock stud is the reversing gear. The larger gear on the bottom left is mounted on a slotted swingarm for adjustment. The bottom right large gear is the changebox input shaft gear which is changeable for size but not position adjustable.
Good Idea to convert your lathe to variable speed motor. You state that you bought the DC 2 HP variable speed at Home Depot,but when I went to this store in Columbus,Ohio I was told that they did not sell electric motors.Did you purchase your motor online? Where did you buy the speed control switch dial?Should the motor fit without any modification?
these machines are machines not only for pastime l m looking for profesional machine l m trying to find ZMM Bulgaria or not and Nardini brazil and l m only find Chinese machines on the market
Jim has freaking awesome automation and fabrication skills. Respect!!
Really nice well-thought-out mods. Excellent. Jim has some skills.
Nice job. I have the same lathe and it rattles like crazy. I need to take it apart and redo the gibs etc.
thanks Jim ,for sharing.very nice informative video.
Glad you liked it!
Excellent inspiration for my lathe improvements. Thank you!

Very good film,its given me some ideas for my own lathe.
Thanks for the video. I would like to learn more about the DRO AND THE CAM LOC.
JIM
Awsome, Jim seems like a really nice guy.
Nice job! I'm looking to buy one of these this spring.
would love to see how you made the reverse feed what gear? and how it is all done i can make what i need other than the gear, what gear are you using to do this? a complete video on how to do this tell me where to find this if you have already done so thanks Eddie
like the indexwheel idea
good stuff, thanks for posting
dro is a must for a lathe... love it great video
Dial indicator
Your website is down :( been moving for a while it seems.
When will the website be back up?
do you have a video of how you made the cam lock on the tail stock
молодец Отец !мне очень понравилось как ты все оборудывал .Класс!
Супер!!!!
love your lathe i really want power crossfeed g9972z i think is the smallest griz offers

i need to do the reversing gear set up on my G0752 also!!
rudd have you heard back from him on this i want to do it not quite sure what gears and what he has done?
how did you make the cam lock for tail stock i need to do this?

Hi Jim! In it's original condition were you able to do threading was the torque ok ? Stay healthy my friend.

He bought the paint there said the motor was from a treadmill. Not sure what you heard..
I still don't understand the index wheel. What does it help you do?
Can you tell me about the variable freq motor that was recommended. What size and what application is used on this motor?
Go to Clough42 youtube site. He has complete series on how to do it. I did mine using his guidance.
Why is this channel dead
Hi Jim, I would like to know wich tools post you are using on your lathe a AXA or BXA. Thanks
BXA is generally for 12" and larger lathes
