Two-wheel grinders

Hehe, my neighbours back yard is 3 meters away from my workshop, and all the chickens were busy with easter supllyes. :D
I wonder if the spring is too strong for the belt tention. What you think?
 
Yes I noticed that you had to really lean into it to get it to move. Hard to tell until it is mounted. Can you change the spring after it is complete?
 
I can trim it with a few cm. I put a bolt to limit the tention arm motion. I will see after I run the motor.
 
I am still laughing at the chickens. the grinders look ok , how many chickens you got .kellyw
 
So when do we get to see it in action, and does it always make that clucking sound? That might get a little annoying, course fried chicken always goes good with a grinder!
 
After I finish the grinders I am planing to build a large grill in my yard. My neighbours won't be happy when they see the chickens grilled. :rolleyes: I can only work on weekends on my workshop. I am working in another town from monday to friday. I will update the thread next week.
 
Can't wait to see an update to this thread! :thumbup:
After watching your clip on the belt tracking experiment you may want to add a handle out front to make it a little easier to overcome the tensioner, while changing belts. You know the power of leverage kind of thing!
Really cool design!
 
It is just clamped to the table for experiment -thats why it shakes so much. I will weld everything together, and tighten every bolt. It will be welded next weekend to a heavy steel construction, where the motor will rest. I will make a handle, that will be screwed to the tention arm for pushing down. There are many details to finish. :) Thanks for looking.
 
Looks pretty useful to me.

I can just imagine what the chickens and stuff are like, no pigs? Lot of pigs in your region too :) Hope things are well in Sofia, this is my favorite time of the year in that region..... as a Kosovar poet/journalist remarked to me over coffee, "the butterflies are coming out of the cocoons." :D
 
Looking very servicable to me!
I'd add a ball to the belt change lever, so you don't accidentally put a dent in your forehead. Looks like it's close to your head.
I'd add a jam nut to the bolt you have all the lock washers on, so it will never loosen up.
And a nice paint job, and it will look better, too.
 
Thanks, guys. I will remove this lever, and make a new lever, twisted to the left and down. My head allmost got a dent while doing testing. :D It is half of the speed on the clip - about 700 RPM. On 1400 it eats steel very fast. :jerkit: . Realy cool to work on such beast.
I made a flat platen adjustment with hardened stainless steel plate 1.4116 up to 58 rockwell. I hope it is enough hard to flat grind to begin. I mount the plate with BISON dual component epoxy. I weld an edge in the down end of a platen base, so it will keep the harden plate from falling off just in case.
