I'm no photographer so you'll have to just deal with the pics..:). The pics
should give you a good idea of what I did. I will briefly explain a few
things again as you now have the pics to look at.
Steel shaft mod..2" long 1/4" thread hex bolt JB welded(epoxied) into a 1/4"
drive 7/16" socket. Let that sit per epoxy destructions. Once cured, I
used a 1/4" drive 1/2" socket turned upside down over the bolt. This socket
is used as a centering device so the whole shaft doesn't wobble while
turning. I then slipped on a normal size 1/4" flat washer so it sits on the
socket. I then put on the stirring arm I made(more on that later). I then
cut two slots in a 1" wide 1/4" hole 'fender washer' and bent the washer
slots over and around the stirring arm. This holds the stirring arm in
place so it doesn't turn as the motor turns the beans. I then put on a 1/4"
nut(duh!) and cranked it down nice and snug. I then did the slotted copper
Couple things...for the bottom socket to fit thru the SC and on the motor
shaft a few simple things need to be done. First, you have to drill out the
bottom hole on the base of the SC(The black plastic base part of the SC, NOT
the metal pan where the beans go!). I followed the web directions and used
a 1/2" bit at an angle to make sure the socket would fit. I would say if
you have a 9/16" bit try that, maybe even a 5/8" bit. It's a little messy
using the drill at an angle with the 1/2" bit and if your not careful it
will tear up the plastic. If all you have is a 1/2" bit make sure you take
your time and that the drill is fully engaged before you touch it to the
plastic. If the bit is touching the plastic base as you pull the trigger it
will likely gouge(sp?)out the base.
Secondly...I sliced off the pointed tip of the motors plastic shaft so the
socket would slip on a little better. Remember, you now have a hex bolt
welded inside the socket acting as a stop. By shaving just a bit off the
point it will let the socket drop down to where it should be.
STIRRING ARM...I made mine exactly how the old one was. It took me a couple
hours of tweaking to get it just right. In the pics you will see how close
the tolerances are to the SC pan. You really want to make sure that the
arms are just a 'hair' above the base. Even if they are rubbing(especially
where the 'bump' is on the pan)ever so lightly it should be fine. If the
arms are to far above the pan you will trap beans and cause the motor to run
back and forth, as I'm sure many of you know.....this would result in a
somewhat uneven roast I think...
I just want to say I did not come up with any of these mods, I just tweaked
them to my preference. The following are the web pages I used, and also my
pics of my tweaks.
I'd also like to say to those that are going to do this make sure and take
your time. Make sure the parts you have fit your setup. Where I used a
certain size socket you may need a different size to get better tolerances.
Just double check everything you do so you don't have to do it twice.
Oh yes, I disables the heating element on the SC also...http://www.bish.ws/coffee/TurboCrazy.htmlGood luck all, any question let me know!">http://pg.photos.yahoo.com/ph/ronf27/album?.dir=f3a0&.src=ph&store=&prodid=&.done=http%3a//pg.photos.yahoo.com/ph/ronf27/my_photoshttp://biobug.org/coffee/turbo-crazy/http://www.bish.ws/coffee/TurboCrazy.htmlGood luck all, any question let me know!
