Russ, thanks for showing that. I've heard lots about converting to belt drive, but had no idea it was such an involved process. I figured you'd just swap motors, take off the gears connecting it to the top of the spindle and replace them with a pulley and belt. Looking forward to seeing the rest of the job. -- Mike
Just when you think you'll never use the Quill........you need the quill...........like making a hole for a bearing for instance............lolol...........Z
Thanks for sharing all this russ. I ordered hole kit from ebay i did not have life to do it all by my self(still lot of work to do on lathe and mill). it was like 150$.
That's a good price. I still don't have this thing put back together 100% and it's turned into a huge nightmare. I'll be sharing my mistakes in the next part of the series so hopefully someone won't do the same.
russtuff i got suprised that belt drive i got have a spindle pulley that screw onto same holes where tachometer peace is standing. I have some doubts that those 2 small holes and screws can hold all the torqe from 3hp motor. Is yours the same?
russtuff good to know. I am at stage to make a bracket for same motor you got(but 3hp). I will go with similar aproach to what hoss did with aluminum cylinder as this thing can shake a lot. Thank you again for all this videos they are great help.
How do u like this mill now that u have had it for a while & would u recommend this model for someones first cnc . Was looking at this mill for a good table top mill & possibly converting it to cnc. Seeing those plastic gears kinda has me thinking twice about these shall mills .
I do think this is a good mill for beginners, because there is so much support in the DIY CNC community. That said, if I were doing this again I would go with an RX45 (or one of the clones). The number one thing that this mill lacks, is rigidity. As long as you realize you should stick with 3/8" end mills and under, you're fine.
Hello, very nice work ! My mill has enbedded quill+spindle also and want to convert it to belt drive, You said that an alternative conversion which you can use quill also, i searched a bit but didnt find any example, could you advice somewhere to me? Is the main idea free z movement to spindle pulley? Thanks
Yes that's right. The only real difference (as I understand it) is how you drive the spindle. In one of my videos I detail how my pulley drives the splined shaft, but if you drive the quill itself then the splined shift is free to drop through the quill for the drawbar to work. I can make a short video if you would like to see the difference.
Hello! Yes, do not think you would need to remove any of the gear assembly to get the quill out. Basically you would just drop the spindle and then hammer or press out the quill. I would very much recommend you remove the entire head and push the quill assembly out with a hydraulic press. If you hammer the quill out (and back in) you could damage the plastic gears that the quill mesh with.
***** Yes, but I've been to busy the last few weeks to get the videos rolled out. I'm making some changes at work in the next few weeks that will free up a lot of my time, so hopefully I'll be able to crank out some videos soon.
the format of this mill is great but its flimsy dick construction is not a selling point. I think they planned its obsolescence from the start so they can sell V1, V2, V3 motors and parts, V4 etc.
You're probably on to something. I really didn't expect to grow out of this mill for a long time so it's hard to say that it was a bad purchase. BUT since I have already outgrown it, messing around with problems like this is beyond aggravating.
Just found your channel and subscribed. Very nice work
Must. Have. MOAR :) Just got my G0704 and absolutely love the videos that you produce. Thanks!
Was trying to get my head around that coverpipe that where springloaded and you saved the day. Thank you!
Thanks for watching!
Great video, thanks for showing this detail, as I am upgrading my motor to belt drive, as soon as it arrives from New Zealand. Thanks, Gary

Thanks for watching. I'm still piecing it together and it's turning out to be harder than I thought too :)
Sweet. Will be looking for your vids on this. I have a G0704 too. It needs more power.
Nice! Very exciting!
Thanks ry :)

I'm not using those screws but I know others have. I wouldn't be surprised if it holds just fine.

No problem. I really need to get my videos done and get my conversion posted. Busy busy.
Wonder if this would apply for mine 6889 grizzly to change from a Morse taper to r8 spindle have a enco version of ronfu
You wouldn't happen to know if the head for your mill is the same as the G0758. Except for a couple of cosmetic differences, they look the same.
No, I do not know.
I see that manual draw bar head now. That's awful. Seems worth it to have a custom unit made so you can use a bigger wrench.

Can you let us know where you got the plans for your cnc conversion? Thank You
Hi! I used Hoss plans, which you can find on his web site www.g0704.com

russtuff Yes i'd like to see that, thanks mate !
Russ, I need to replace the quill bearings... is it possible to remove the quill drive without removing the rest of the gears? Thanks.

Yes, do not think you would need to remove any of the gear assembly to get the quill out. Basically you would just drop the spindle and then hammer or press out the quill.
I would very much recommend you remove the entire head and push the quill assembly out with a hydraulic press. If you hammer the quill out (and back in) you could damage the plastic gears that the quill mesh with.
where did you purchase the upgraded motor from?
+Blackie9900 I got it on ebay, for under $100 including shipping. Do a search for something like 2.8 treadmill motor.
if you want to drill 1 hole
is there g cod to used for that
Yes, G81 to drill, or G83 to peck drill. See: linuxcnc.org/docs/html/gcode.html
thank you
any progress?
