Grinder build finished
Here is the grinder that I have been working on, with the exception of paint its finished!!
I would like to thank the people here on this forum that took the time to answer my questions regarding the build. The pulley arrangement on this grinder probably has some of you wondering, well it ended up that way because not knowing any better I purchased a 3450 RPM motor thinking that I would run a VFD. After the motor arrived I found that a VFD was not affordable on my budget. So to make lemon-aid out of lemons I build a ?jack-shaft? to achieve my desired belt speeds. I was not sure how this would turn out but it is working better than I expected, if I were to do it over again (and still could not afford a VFD) I would not change a thing. My estimations on the belt speeds are as follows (RPM) 1.75? motor pulley 2.5motor pulley 725 1035 1030 1480 2030 2900 2900 4152 One advantage to this system is I only have to change the pulley on the motor ($3.00) and now have eight speeds. This still is not as convenient as a VFD but it is quick and easy to do (just remove one set screw) and is the next best thing to a newbie on a shoestring budget. To change the belt speed you just move the red handle toward the aft of the machine and the jackshaft moves 1? closer to the drive shaft giving ample belt slack to move the belt to the desired location and the motor ?lifts? on its hinge, then move the handle to the front position and it ?locks? in place. Now if you guys can stop laughing at the monstrosity I created, your input both positive and negative as well as ideas for improvement would be much appreciated.

Hey! Nice Work!
Nothing wrong with a lil monstrosity now and then, even more impressive with all them spinnin parts! Check EBAY for a VFD if you still want to run one, I got mine for $25 I think. Its DC, but there are a lot of them on there. |
