Re: [papercreters] Re: Spacesman's version of McCain Scissor mixer & Foam Grinder

Do you have any idea how much torque and brute power is required to chop even 50 gallons of paper pulp? A wooden pulley would be no match for Spaceman's creation. I'm thinking the reason Mike McCain moved on from this design to big batch truck mounted mixers is because of the amount of effort and engineering required to make this design work. I notice that no one has posted any pictures and or descriptions of a working model. The reason tow mixers or stationary mixers using a car differential work so well is that the differential is very sturdy and can hold up to the stress of the mixing. --- On Mon, 10/29/12, JayH <slurryguy@yahoo.com> wrote: From: JayH <slurryguy@yahoo.com> Subject: [papercreters] Re: Spacesman's version of McCain Scissor mixer & Foam Grinder To: papercreters@yahoogroups.com Date: Monday, October 29, 2012, 4:35 AM   It is a rather simple task to make your own V-Belt pulley out of wood. Yes, Wood. You have a table saw right? Check out this website. One of the best websites out there. http://woodgears.ca/cider/motorizing.html Matthias Wandel is what we called as I was growing up, "A Dude..... A righteous smaaaaart DUUUUUUDE!!!" If you paint your wooden pulley with a waterproof sealer, it should be able to withstand the wet environment. If you ever attempt to use that thing to grind up styrofoam, better put a lid on it. Those little bits of foam will pick up static electricity, stick to everything, and you'll soon be walking around looking like the abominable snowman. On second thought... go ahead and grind styrofoam without a lid, but make absolutely sure you post photos. heh heh heh Spaceman wrote:------------------------ Yesterday I did a second test with water and paper, and found that the pulley on the dryer motor just won't get enough grip on the V belt to make it spin with a load. I had other things to do and again today, so maybe tomorrow I'll dig around and find a suitable pulley. I didn't really want to go larger because I like the speed and torque ratio, but I'm pretty sure I don't have a V belt pulley that small. I definitely don't have a larger pulley for the blade shaft and calling around to stores didn't turn one up. It is the wrong season for cooler parts.
