I was wondering what kind of torque would be lacking with all those kits. This makes more sense to me. How is milling operations on this set up though rather than drilling? I have 2 drill presses, No need for another glorified one and want to keep milling operation optimal. Nice job
Hey Richard, good video and valuable information. I want to do a belt drive conversion on my G0704, but like you, most of what I use my mill for is low RPM work. Any chance you can post the part numbers or links to the parts you used?

I think I got a 15.5" belt
Tim, did you find the parts? I am having trouble with the links. I am starting to wonder if I couldn't just make the pulleys on my Lathe? Is the belt a timing belt or V belt?
Tim, I ordered a replacement for my chewed up gear, but I may examine a diy belt/pulley system. I do want to retain the quill so I think that complicates things?
SureMotion timing pulley, steel, 3/8in L pitch, 32 tooth, 3.8in pitch diameter, 1/2in bore, hub with flanges. For use with 1/2in wide belt www.automationdirect.com/adc/shopping/catalog/power_transmission_(mechanical)/synchronous_drives_(timing_belts_-a-_pulleys)/timing_pulleys_(sprockets)/l_(0.375_inch_pitch)_timing_pulleys/apb10l050bf-375
I still dont understand why. Gear drive is better than a belt drive any day of the month. Belts stretch, gears do not. Never seen a race car go from a gear drive to a chain roller ever. I agree with the rpm statement. High speed tools are designed for HS operations. Increasing the speed of a cheap overseas machine by 3 or 4 times is idiotic. It will grenade eventually, it is just a matter of time. I pulled the headstock and am replacing all the bearings. The cone and race will be changed to angular, the other bearings will receive an upgrade. There will be way less resistance so the motor will spin easier and cuts should improve dramatically. Make chips that dont need dips!
The reason for the switch is the factory gears are plastic and are not as strong as the belt. If they were bigger or made from stronger material then they would be better then the belt option for sure.

@@RVJimD - No, I have not been able to find the parts. I've been considering making them too.

spinning that 5/8 bit a bit too fast brother
yeah I agree. The motor still lacks low end torque. I still have to run my large bits on the fast side so it doesn't fall on it's face.
This mill has plastic gears???
The 2 tiny screws in the spindle arbor is enough for all that torque?
so far it still holding up. :/
