I was impressed with that company and employee's. I would estimate when I teach a class inside a large employer like them one of the students will ask me "How much does someone on the outside get paid to do this?" Not one of my 10 students asked me that. The newest hire in my class had been there 3 years. One had been there 44 years, his partner tech had been their 42. They were going to retire in 2 years they said. They had been scraping and rebuilding "headers" for for years and had 3 BIAX scrapers, 1 flaker, many masters and 2 Square Masters. They had never used the longer 150 series blades or sharpened the blades to 60 mm radius. They used the blades as they came in and scratched the living heck out of the out of the ways.
I see that a lot all over, they buy either a Sanvik, Anderson or Biax blade and assume it can be used as is. They are mistaken. That is why BIAX and Anderson sell radius gages. A few years ago after someone in here told the group Sanvik blades that are damn near flat have to be used that way. I contacted Sanvik and they said, they have no idea what people will be scraping. Barnacles of ships, paint off of steel beams, way scraping, etc. So they grind them flat and expect the customer to sharpen them they way they want them.
CCI had 2 Glendo Accu-Finish 2's but only bought 260 grit wheels. Luckily I brought along a 600 and 1200 grit wheel and we used them until new ones came in that they ordered on day one after I showed them how much sharper the finer wheels worked. They only did circles and X's. Never got more then 5 PPI, they stoned the living crap out of the ways too. hey said they assumed more percentage was better. One told me the machines got scores after about 2 years. The install new lube systems too on their rebuilds. Now they should be good. Just a week of training and that's all it took. Damn proud of them and how fast they figured it out. 10 more Kid's and 10 more brothers of you Stu!.. LOL
