Being shut in with the cold recently, I made an online belt speed calculator. http://dcknives.com/public/belt_speed.php If you want to build up a grinder and understand what speeds are possible with different ratios, motors and so on, then give it a whirl. Kindly let me know if you have any issues or would like to see something else added to it. Continuous improvement. Dan
Dan, that's amazing. Knife-maker, engineer, programmer, beer maker (brewer i guess), musician and on.. a true renaissance man. You are the Leonardo DaVinci of the knife-making world... (I almost wrote DiCaprio... that would've made no sense..)
Hey, since when do you have a bevel calculator on your site? I've been missing that all this time? I could never find the other one i use when i needed it.
Dan, I think I scored when I bought on kijiji a baldor pressure washer with a 3 HP Baldor 220 volt motor in excellent working condition for $100.00. I have 220 in my shop and want to power a kmg 2X72 grinder with the motor. After I hauled it to the shop...really heavy it looks so big I'm thinking it may be way too much. What do you think? Will it work?
Yes, sure it will work. Three horse is probably a 145 frame and will have a big 7/8" shaft, so finding drive wheel won't be as easy as a 5/8" or 3/4" bore wheel. And you'll likely need 30 A double pole breaker and 30 A NEMA 6 receptacle, but you certainly won't lack power. Dan
Running a 2 Hp 3 phase 220V motor on my sander with VFD, 7/8" shaft means I get custom wheels or order from industrial suppliers in the States. Not sure what it will take to stall the belt and pretty sure I don't want to know.
How many horsepower John? I have a 2 hp running with a VFD running on a 20 A double pole breaker. I stalled it once (a piece got jammed down between the work rest and platen) and it tripped the circuit breaker. I had to reset the VFD as well as it alarmed on over current. That was scary. I cannot imagine stalling it intentionally. Dan
