casting rig sand muller finished
Posted: Wed Dec 15, 2010 1:04 am
hi guys,
as some of you know i started a sand casting project a while back.
the idea was to repop parts i need in large quantities cheaply.
as with everything i do progress is very slow.
watching grass grow could be more exiciting i suppose.
anyway a major component of the casting rig is a sand muller.
it's basically a giant mix-o-matic that conditions the sand and clay or petro bond into a usable mix.
i copied one i found on the net.
see youtube video below:

as i'm not about pretty mine is kinda ugly.
since it's a low buck job i had to do the welds so they aren't pretty either.
it took a bit of extra unexpected work too because my cement mixer ran clockwise.
since the copied one runs counter clock wise when i first started my machine it ran backwards.
rather than start over i went back to the net and figured out how to reverse the motor even though it wasn't reversable.
basically i switched where the power goes in and out of the windings.
then the gear bearings failed so i had to take everything apart again and replace the bearings.
the air around my shop has been pretty blue lately with my language.
but as with everything if you keep going eventually the gremlins give up and go home.
it works fine but i can't post a video as the gremilins have found a new place to bugger the works.
next i need to build an osilating riddle.
ALL THIS BECAUSE NEED MORE PARTS THAN I CAN AFFORD TO BUY.
these dang karts are fun but man the work you gotta do!!!
