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.
Hi Jorge, 1. At this time we do not have the kit available for BF20; but we will be offering it eventually; 2. I'm not aware of that detail; my understanding is that the only parts that are different for the BF20 are the sensor and the pulleys; thus, "I …

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 …

Originally I had been considering a G0704 with the dovetail column but seeing the size difference for equal price made me wonder if I wouldn't be far better off with the much more hefty (size wise) G0705. What are the practical benefits of the dovetail vs. round column mill drills? What are the practical benefits of a gear drive vs. a belt drive?
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.

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.

I did a DIY belt drive on my G0704. First of all, I would question your bearing seating and preload. Second, the upper bearing tube from the original G0704 gear head system had nearly 0.030" runout on the inside bore (a non critical surface). I know this part is replaced in your kit, but verify the new tube is running true.

Nothing bad about the other variants, and some of the vendors out there are superb (PM Matthews), but the G0704 is for me, the best blank canvas for modifications. Eventually, I will CNC it, and add a larger motor and belt drive (3 phase with a VFD, that I already have).
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 ...

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, …

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.
