I apprenticed for 4 years with a master machinist, Klaus Wirbelauer
WOW ! That's a name from the past. I visited with Klaus on many an occasion, back in the day. He was very kind and generous until you (I) asked a really stupid question.
*that* is wonderful! Tell me more about it - are you in the Burlington, NC area? Did you meet Andy, who had been the repair technician before me?
...more than once, I disappointed Klaus by doing numb-nuts mistakes after he had just told me what to do but, I'm the machinist I am today due to his influence and passion for machining! He's had a few health concerns in the last year and I'm planning on going to see him within the month. Carolina Biological discontinued the microscope repair machine shop (after 45 years) but Klaus still does work in the "kitting" dept and his wife is head of customer service at CBS!
