We had a request for a status update on the Squeezebox project this morning. I have been making steady advances over the last month, but have not been diligent about posting them… The good news is I know how to thread-mill tapered threads in a blind hole now (ugh!). I will just paste my reply to the email here.
“Hi xxx,The last mechanical part is done… finally. We have made a jig for modifying the stock tool boxes and are waiting for a cutting bit to arrive (today). I have been unhappy with the control system as very occasionally it will lock up and not exhaust properly. It seems to be a random problem found only when repetitively cycle testing the units, unfortunately just under half of them do it eventually. We have a customer who is an engineer specializing in ‘controls’ looking at it and he thinks it will need another valve. I am sending him additional parts today to try.Thanks for your interest and patience,Mike”
