Topic: Pin Failure on RK (4 msgs / 93 lines)
1) From: Jamie Dolan
Hi;
I had a (twice during one roast) failure of the pin to hold the door
shut on my RK.  I know I read in the past that someone here said that
the door on their RK was so sticky that they did not even need to use
the pin.  However, that is not the case for me.  I lost over half a
pound of sanani to the grill tonight, on the plus side, I was watching
pretty closely, and realized what happened before the whole drum
dumped.
This was using the old 4 RPM motor.  I am upgrading to the 50 RPM
motor, I have it on order.  If I was was using a 50 RPM motor, I am
sure I would have lost the whole batch.  It was kind of a mess as the
beans that dumped caught fire, while I was still trying to finish the
roast with the beans I had left in the drum.
I am sure I can come up with some way to secure the pin, I was just
wondering if anyone else has had this , um, experiance, and what kind
of solution you came up with.
I've done about 40 roasts this year in this drum and never had the pin
fall out before.
Thanks for listening, I had to vent, just after I cleaned up the
entire grill and dedicated it to roasting, I dumped beans all over the
fire box and set them ablaze!!!
Tomorrow will be drinking, San'ani with about 10% robusta, mixed
between City and French (maybe some of it is French+, thats a nice way
to say I am picking out burnt beans) because I had to stop the drum
while I fixed the pin.  I normally would allow 5 days rest, but have
been really busy and am down to my last ounce or so of roasted beans.

I replaced the stock pin with the same type from Ace hardware, but half the 
thickness and gave it an extra bend to keep it in place.  I found the stock 
pin too thick for my liking as I wanted to be able to pull the pin out 
easily and quickly with one (ove gloved) finger using the chain.  The extra 
bend has kept in place for, it seems like, a couple years now averaging 
about 6 pounds a week.
Respectfully,
Rich Adams

Jamie,
Sorry to hear about that.  I have one of the 'sticky-door' drums; however, the linchpin is getting weak.  I've crimped it a bit with pliers and it still holds.  You are right about needing to fix this before you start with the 50rpm motor.  However, I think you'll appreciate the greater level of evenness attainable with the faster motor.  I know I do!
Cheers,
Paul

I'm replacing the pin with a stainless latch. There'll be no episode of the
red waffle pattern on my forearms when dumping the roast!
I'm no metallurgist, I hope the 450 F max roasting temperature won't ann=
