they are threaded, the would be a right hand thread, so that with the direction of the shaft turning it would only tighten. this is also so that you can take one side off to change out rollers or what not. also if it does not work i figure ill just drill a 1/32 hole through an pin it in place at an off center....remember all mine is a concept right now.. but... i am trying different things...
for my materials i did what the local stock house had in.. not what they could order, because i did not want to wait, this is why most of my materials are standard 6061 aluminum 1018, and 304 SS with a 8 percent student discount it still cost me 42 with materials, mainly the SS cost me 28 dollars of the total cost for 13 x 1 - 1/2 round
too answer the questions about mine, they are 6" long, i based my design on the barley crusher and monster roller... (this one might be redundant) i am treading the ends in the end of my "cam" in because i figure that since its a right hand thread it would only be under tightening torque, so there would be only very little chance that would allow it to untighten. these would also use lockite to secure the thread in place. i figure if this does not work ill drill a hole in the cam and pin it (my original design had pins in this and no threads)
yes i planned on placing my cam end on after the roller is placed on... again this might be a problem.. but for me i made that rod 1/2 inch so that it would not flex and could take a 1/4 thread and load of what it would take to crush barley. as well as, if i feel the need to change out the bushings to bearings later, and/or need to replace them, i could with ease of just removing the housing and then the end of the "cam"
right now i have the bushing pressed into the roller, they are concentric to a couple tho.
note these might be redundant because im abit drunk on HB
... thanks superbowl!
mrfurlly ill be sending you design tomorrow when i can work programs correctly ( hope all this make sense of why i did it that way)
