My first concern is for the machinist. Not only for his health, which is paramount, but also for his feelings, which can actually impact his health. The thing is, it is hard to know if the remaining work looms over him as worrisome unfinished business of which he would gladly be free, or if taking the work elsewhere would make him feel he had failed, lending itself to depressed feelings. For myself, I would probably tend more toward the latter. With that in mind, I would be hesitant to suggest he give up the work - and of course there is no question he should be paid more than fairly for his time. I am not in a tearing hurry at this point, although if this drags out more than another 60 days or so, I might say we would have to ask him to give in to pragmatism. Until then, I would be willing to wait for him to recover and even then not press him for output. On the other hand, if he feels he would rather not have to worry with the project right now, then I am not unwilling to face a reasonable premium to have the work done elsewhere. Either way, I would like to make it clear to him this is not something he needs to fret at this time.
