A bit of back story is needed, I think. Shortly after I got my mill, I managed to break one of the plastic gears inside the mill head (my own fault), which led me to doing the belt drive upgrade. The problem was, the rather weak stock motor sometimes wasn't up to the task at hand, there just wasn't enough torque at low rpms being run direct.
The plastic gear will eventually go. Believe me.. almost every G0704 owner has "been there done that". If nothing else, order a couple extra of the plastic 37 tooth gears that drive the secondary drive off the brass motor gear. Bet better yet, look as Hoss's belt drive info and make the upgrade.
Lots of people do a belt drive conversion, and there are plans available for that. There are a lot of users on the CNC Zone discussion board, under the "Benchtop Machines" …
I suppose an indusus person could calculate the rpm based on the original gear train ratio compared to the new belt ratio - I used a 25 tooth motor pulley with a 36 tooth spindle pulley. I had seen one on the net done with two 32 tooth pulleys but that one indicated that the bearings would not take the extra RPM, so I opted to gear it down ...

Moreover, most parts of the Grizzly G0704 are straightforward, allowing for seamless conversion. The Grizzly G0704 is also a popular contender for CNC conversion because it has a large work area and square vertical column, making it simple to integrate new hardware. A Grizzly G0704 comes with three axes to cut metal: x, y, and z.
Just the upgrades in the drive system and column more than make up the slight difference you will have to pay for a DRO system. I bought a DRO-PRO 3-axis glass scale (GS30 scales...good size for a PM25/G0704) for $800. Very good DRO. The only commercially available pulley upgrade for the G0704 will set you back hundreds of dollars.

Grizzly G0704 belt drive kit. I bought this belt drive kit from Home Machine Shop. It's a nice kit easy to install and works great. I have used it for 6 months or so. belt is still in good shape never crashed or stalled where the belt slipped. I have all the fasteners to install. I was able to achieve about 5000 RPM with this set up.
I do not know why but I think the stock motor (or the controller) on my G0704 is on the fritz. It loses torque for no reason and even when it's at full torque it will only spin at very high speed, which means you can't drill steel with it (work hardening). I'm really considering replacing it with the D80C motor, but so few information are out there for it, and I emailed Benchtop …

New to the site and just in the middle of my own belt drive conversion albeit on an Optimum BF20. I had been wondering how to fix the Drive pulley onto the spindle carrier and see now how its done on the G0704. The 5mm flange that sticks up has no screw holes in it on the Optimum as the RPM's are measured with a sensor and magnets.
Anxiously awaiting arrival of the new Grizzly G0704. ETA, Monday 3/24. The plan is to convert this mill to CNC per Hoss - Phase II and also belt drive, simple manual ATC, extended Y- travel, rear mounted Y-axis stepper and possibly a larger motor. I have very little experience operating a mill, but I understand basic lathe operation and own a 9x20.
The mill is almost identicle to the G0704. The belt drive on the PM machine is great. Very quiet, and no gears to worry about breaking. If you go with the 704 plan on doing the belt upgrade, you will be very happy. Matt has a shipment of PM-25MV's coming at the end of the month. He may have some that are not spoken for.
On my previous upgrade to the G0704, I designed a moderately complicated spindle belt drive and pneumatic drawbar assembly. This took advantage of a 1.8kW, 5000 RPM, 4.2 Nm continuous torque, 11.1 Nm peak torque, 90mm frame AC servo I had access to. ... my belt drive design left it easy to modify and replace the pulleys as needed to achieve ...
