Great progress and a minor setback.

Wednesday, November 3rd, 2010

We picked up all of the parts of the roaster today, except the combustion chamber, and dropped them off at the roastery. We had to pick up a few other parts, so we didn’t get as far as we wanted. We have ten full days left though, and are doing really well so it should be installed and working far before then. Today being the first day of the actual assembly, we did have at least a minor problem with the roast chamber. When we dropped off the roast chamber we noticed that the gap between the sides of the perforated plate and the roast chamber walls was too large. The gap is large enough to let smaller beans through (I included pictures of the gaps along with the pictures of the move for reference). I went back to the drawings to see what was specified and it very clearly specifies that the perforated plate should extend the length of the roast chamber. Having said that it is also my responsibility as project manager to ensure that the parts are built as specified. Unfortunately in this case, once it was built there was nothing that could be done. It was specified in the drawing and discussed with the sheet metal company several times, beyond that there was not much that could have been done in terms of preventative measures. So now what is done is done and all that is left to do is to decide what steps should be taken to solve the problem. In this case the only solution is to replace the parts. The gaps in the sides are small and will only allow the smallest of beans to fall through, but this is a major problem, the beans that are allowed to fall through will burn and contaminate the current roast and any subsequent roasts.
